I am using WordPress, and I need to create a function to check for typos in a custom table, by comparing the single values with a comparison table. The values to be checked are animal species names, and they stored as follows in table A
id | qualifying_species
----------------------
1 | Dugong dugon, Delphinus delphis
2 | Balaneoptera physalus, Tursiops truncatus, Stenella coeruleoalba
etc.
These values must be checked for typos by matching them with table B which contains a simple list of species name as a reference
id | species_name
----------------------
1 | Dugong dugon
2 | Delphinus delphis
3 | Balaneoptera physalus
4 | Tursiops truncatus
5 | Stenella coeruleoalba
Here's the code I prepared
function test(){
global $wpdb;
$query_species = $wpdb->get_results("SELECT qualifying_species FROM A", ARRAY_A);
foreach($query_species as $row_species)
{
$string = implode (";", $row_species);
$qualifying_species = explode(";", $string);
//echo '<pre>';
//print_r($qualifying_species);
//echo '</pre>';
foreach ($qualifying_species as $key => $value) {
//I get here the single species name
echo $value . '<br>';
//I compare the single name with the species list table
$wpdb->get_results("SELECT COUNT(species_name) as num_rows FROM B WHERE species_name = '$value'");
//if the species is written correctly, it will be counted as 1 with num_rows
//if the species is written wrongly, no match will be found and num_rows = 0
echo $wpdb->num_rows . '<br>';
}
}
}
The echo was to check the results of the function. The Mysql query works when I do it on PHPMyAdmin, but it seems that something is wrong with the PHP loop that I wrote. For each $value echoed I have a result of 1 echoed with $wpdb->num_rows even if $value presents typos or doesn't exist in table B
What am I doing wrong?
Possible solutoin for MySQL 5.7.
Create a procedure (must be performed only once):
CREATE PROCEDURE check_table_data ()
BEGIN
DECLARE sp_name VARCHAR(255);
DECLARE done INT DEFAULT FALSE;
DECLARE cur CURSOR FOR SELECT species_name FROM tableB;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done := TRUE;
OPEN cur;
CREATE TEMPORARY TABLE t_tableA SELECT * FROM tableA;
FETCH cur INTO sp_name;
REPEAT
UPDATE t_tableA SET qualifying_species = REPLACE(qualifying_species, sp_name, '');
FETCH cur INTO sp_name;
UNTIL done END REPEAT;
CLOSE cur;
SELECT id, qualifying_species wrong_species FROM t_tableA WHERE REPLACE(qualifying_species, ',', '') != '';
DROP TABLE t_tableA;
END
Now, when you need to check your data for unknown species and misprintings you simply execute one tiny query
CALL check_table_data;
which will return id for a row which have a species value not found in tableB, and this species itself.
fiddle
The code assumes that there is no species_name value which is a substring of another species_name value.
The procedure do the next: it makes the data copy then removes existent species from the values. If some species is wrong (is absent, contains misprint) it won't be removed. After all species processed the procedure selects all rows which are not empty (contain non-removed species).
You maybe could do this in the same query :
SELECT *
FROM table_a
INNER JOIN table_b ON FIND_IN_SET(species_name,replace(qualifying_species,';',','))
if you want to find non-existent values, use something like this:
SELECT *
FROM table_b
LEFT OUTER JOIN table_a ON FIND_IN_SET(species_name,replace(qualifying_species,';',','))
WHERE table_a.id IS null
I wanted to implement a notification system for our school, it's a php/mysql webapp that is not opened for public, so it doesn't receive much traffic. "daily 500-1000 visitor".
1. My initial approach was using MYSQL triggers:
I used a Mysql AFTER INSERT trigger to add records to a table named notifications. Something like.
'CREATE TRIGGER `notify_new_homwork` AFTER INSERT ON `homeworks`
FOR EACH ROW INSERT INTO `notifications`
( `from_id`, `note`, `class_id`)
VALUES
(new.user_id,
concat('A New homework Titled: "',left(new.title,'50'),
'".. was added' )
,new.subject_id , 11);'
This kind of black magic worked very well, yet i couldn't keep track of if this notification is new "to show count of new notifications for user".
so i added a page named notifications.
Notifications are retrieved with something like
SELECT n.* from notifications n
JOIN user_class on user_class.class_id = n.class_id where user_class.user_id = X;
Note: table user_class link user to class "user_id,class_id,subject_id" -subject is null unless user is a teacher'
Now my next challenges are.
how to keep track of new vs old notifications per user?
how can i aggregate notifications that are similar to user into one row ?
example if 2 user commented on something, then do not insert a new row, just update the old one with something like 'userx and 1 other commented on hw'.
Thanks alot
Edit
As per answer below, to set a read/unread flag on row, i will need to have a row for each student not just a row for the whole class.. which means editing the trigger to something like
insert into notifications (from_id,note,student_id,isread)
select new.user_id,new.note,user_id,'0' from user_class where user_class.class_id = new.class_id group by user_class.user_id
Well this question is 9 months old so i'm not sure if OP is still in the need of an answer but due the many views and the tasty bounty I would like to also add my mustard (German saying..).
In this post I will try to make a simple explained example on how to start building a notification system.
Edit: Well ok this turned out way, way, way longer than I expected it to be. I got really tired in the end, i'm sorry.
WTLDR;
Question 1: have a flag on every notification.
Question 2: Still store every notification as a single record inside your database and group them when they are requested.
Structure
I assume that the notifications will look something like:
+---------------------------------------------+
| ▣ James has uploaded new Homework: Math 1+1 |
+---------------------------------------------+
| ▣ Jane and John liked your comment: Im s... |
+---------------------------------------------+
| ▢ The School is closed on independence day. |
+---------------------------------------------+
Behind the curtains this could look something like this:
+--------+-----------+--------+-----------------+-------------------------------------------+
| unread | recipient | sender | type | reference |
+--------+-----------+--------+-----------------+-------------------------------------------+
| true | me | James | homework.create | Math 1 + 1 |
+--------+-----------+--------+-----------------+-------------------------------------------+
| true | me | Jane | comment.like | Im sick of school |
+--------+-----------+--------+-----------------+-------------------------------------------+
| true | me | John | comment.like | Im sick of school |
+--------+-----------+--------+-----------------+-------------------------------------------+
| false | me | system | message | The School is closed on independence day. |
+--------+-----------+--------+-----------------+-------------------------------------------+
Note: I don't recommend to group the notifications inside the database, do that on runtime this keeps things a lot more flexible.
Unread
Every notification should have a flag to indicate if the recipient has already opened the notification.
Recipient
Defines who receives the notification.
Sender
Defines who triggered the notification.
Type
Instead of having every Message in plain text inside your database create types. This way you can create special handlers for different notification types inside your backend. Will reduce the amount of data stored inside your database and gives your even more flexibility, enabled easy translating of notification, changes of past messages etc..
Reference
Most notifications will have a Reference to a record on your database or your application.
Every system I have been working on had a simple 1 to 1 reference relationship on a notification, you might have an 1 to n keep in mind that I will continue my example with 1:1. This also means that I don't need a field defining what type of object is referenced because this is defined by the notification type.
SQL Table
Now when defining a real table structure for SQL we come to a few decisions in terms of the database design. I will go with simplest solution which will look something like this:
+--------------+--------+---------------------------------------------------------+
| column | type | description |
+--------------+--------+---------------------------------------------------------+
| id | int | Primary key |
+--------------+--------+---------------------------------------------------------+
| recipient_id | int | The receivers user id. |
+--------------+--------+---------------------------------------------------------+
| sender_id | int | The sender's user id. |
+--------------+--------+---------------------------------------------------------+
| unread | bool | Flag if the recipient has already read the notification |
+--------------+--------+---------------------------------------------------------+
| type | string | The notification type. |
+--------------+--------+---------------------------------------------------------+
| parameters | array | Additional data to render different notification types. |
+--------------+--------+---------------------------------------------------------+
| reference_id | int | The primary key of the referencing object. |
+--------------+--------+---------------------------------------------------------+
| created_at | int | Timestamp of the notification creation date. |
+--------------+--------+---------------------------------------------------------+
Or for the lazy folks the SQL create table command for this example:
CREATE TABLE `notifications` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`recipient_id` int(11) NOT NULL,
`sender_id` int(11) NOT NULL,
`unread` tinyint(1) NOT NULL DEFAULT '1',
`type` varchar(255) NOT NULL DEFAULT '',
`parameters` text NOT NULL,
`reference_id` int(11) NOT NULL,
`created_at` int(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
PHP Service
This implementation depends completely on the needs of your application, Note: This is an example not the golden standard on how to build an notification system in PHP.
Notification model
This is an example base model of the notification itself, nothing fancy just the needed properties and the abstract methods messageForNotification and messageForNotifications we expected being implemented in the different notification types.
abstract class Notification
{
protected $recipient;
protected $sender;
protected $unread;
protected $type;
protected $parameters;
protected $referenceId;
protected $createdAt;
/**
* Message generators that have to be defined in subclasses
*/
public function messageForNotification(Notification $notification) : string;
public function messageForNotifications(array $notifications) : string;
/**
* Generate message of the current notification.
*/
public function message() : string
{
return $this->messageForNotification($this);
}
}
You will have to add a constructor, getters, setters and that kind of stuff by yourself in your own style, i'm not going to provide a ready to use Notification system.
Notification Types
Now you can create a new Notification subclass for every type. This following example would handle the like action of a comment:
Ray has liked your comment. (1 notification)
John and Jane liked your comment. (2 notifications)
Jane, Johnny, James and Jenny liked your comment. (4 notifications)
Jonny, James and 12 others liked your comment. (14 notifications)
Example implementation:
namespace Notification\Comment;
class CommentLikedNotification extends \Notification
{
/**
* Generate a message for a single notification
*
* #param Notification $notification
* #return string
*/
public function messageForNotification(Notification $notification) : string
{
return $this->sender->getName() . 'has liked your comment: ' . substr($this->reference->text, 0, 10) . '...';
}
/**
* Generate a message for a multiple notifications
*
* #param array $notifications
* #return string
*/
public function messageForNotifications(array $notifications, int $realCount = 0) : string
{
if ($realCount === 0) {
$realCount = count($notifications);
}
// when there are two
if ($realCount === 2) {
$names = $this->messageForTwoNotifications($notifications);
}
// less than five
elseif ($realCount < 5) {
$names = $this->messageForManyNotifications($notifications);
}
// to many
else {
$names = $this->messageForManyManyNotifications($notifications, $realCount);
}
return $names . ' liked your comment: ' . substr($this->reference->text, 0, 10) . '...';
}
/**
* Generate a message for two notifications
*
* John and Jane has liked your comment.
*
* #param array $notifications
* #return string
*/
protected function messageForTwoNotifications(array $notifications) : string
{
list($first, $second) = $notifications;
return $first->getName() . ' and ' . $second->getName(); // John and Jane
}
/**
* Generate a message many notifications
*
* Jane, Johnny, James and Jenny has liked your comment.
*
* #param array $notifications
* #return string
*/
protected function messageForManyNotifications(array $notifications) : string
{
$last = array_pop($notifications);
foreach($notifications as $notification) {
$names .= $notification->getName() . ', ';
}
return substr($names, 0, -2) . ' and ' . $last->getName(); // Jane, Johnny, James and Jenny
}
/**
* Generate a message for many many notifications
*
* Jonny, James and 12 other have liked your comment.
*
* #param array $notifications
* #return string
*/
protected function messageForManyManyNotifications(array $notifications, int $realCount) : string
{
list($first, $second) = array_slice($notifications, 0, 2);
return $first->getName() . ', ' . $second->getName() . ' and ' . $realCount . ' others'; // Jonny, James and 12 other
}
}
Notification manager
To work with your notifications inside your application create something like a notification manager:
class NotificationManager
{
protected $notificationAdapter;
public function add(Notification $notification);
public function markRead(array $notifications);
public function get(User $user, $limit = 20, $offset = 0) : array;
}
The notificationAdapter property should contain the logic in direct communication with your data backend in the case of this example mysql.
Creating notifications
Using mysql triggers is not wrong, because there is no wrong solution. What works, works.. But I strongly recommend to not let the database handle application logic.
So inside the notification manager you might want to do something like this:
public function add(Notification $notification)
{
// only save the notification if no possible duplicate is found.
if (!$this->notificationAdapter->isDoublicate($notification))
{
$this->notificationAdapter->add([
'recipient_id' => $notification->recipient->getId(),
'sender_id' => $notification->sender->getId()
'unread' => 1,
'type' => $notification->type,
'parameters' => $notification->parameters,
'reference_id' => $notification->reference->getId(),
'created_at' => time(),
]);
}
}
Behind the add method of the notificationAdapter can be a raw mysql insert command. Using this adapter abstraction enables you to switch easily from mysql to a document based database like mongodb which would make sense for a Notification system.
The isDoublicate method on the notificationAdapter should simply check if there is already a notification with the same recipient, sender, type and reference.
I cannot point out enough that this is only a example. (Also I really have to shorten the next steps this post is getting ridiculously long -.-)
So assuming you have some kind of controller with an action when a teacher uploads homework:
function uploadHomeworkAction(Request $request)
{
// handle the homework and have it stored in the var $homework.
// how you handle your services is up to you...
$notificationManager = new NotificationManager;
foreach($homework->teacher->students as $student)
{
$notification = new Notification\Homework\HomeworkUploadedNotification;
$notification->sender = $homework->teacher;
$notification->recipient = $student;
$notification->reference = $homework;
// send the notification
$notificationManager->add($notification);
}
}
Will create a notification for every teacher's student when he uploads a new homework.
Reading the notifications
Now comes the hard part. The problem with grouping on the PHP side is that you will have to load all notifications of the current user to group them correctly. This would be bad, well if you have only a few users it would probably still be no problem, but that doesn't make it good.
The easy solution is to simply limit the number of notifications requested and only grouping these. This will work fine when there are not many similar notifications (like 3-4 per 20). But lets say the post of a user / student gets about a hundred likes and you only select the last 20 notifications. The user will then only see that 20 people liked his post also that would be his only notification.
A "correct" solution would be grouping the notifications already on the database and selecting only some samples per notification group. Than you would just have to inject the real count into your notification messages.
You probably didn't read the text below so let me continue with a snippet:
select *, count(*) as count from notifications
where recipient_id = 1
group by `type`, `reference_id`
order by created_at desc, unread desc
limit 20
Now you know what notifications should be around for the given user and how many notifications the group contains.
And now the shitty part. I still could not find out a better way to select a limited number of notifications for each group without doing a query for every group. All suggestions here are very welcome.
So I do something like:
$notifcationGroups = [];
foreach($results as $notification)
{
$notifcationGroup = ['count' => $notification['count']];
// when the group only contains one item we don't
// have to select it's children
if ($notification['count'] == 1)
{
$notifcationGroup['items'] = [$notification];
}
else
{
// example with query builder
$notifcationGroup['items'] = $this->select('notifications')
->where('recipient_id', $recipient_id)
->andWehere('type', $notification['type'])
->andWhere('reference_id', $notification['reference_id'])
->limit(5);
}
$notifcationGroups[] = $notifcationGroup;
}
I will now continue assuming that the notificationAdapters get method implements this grouping and returns an array like this:
[
{
count: 12,
items: [Note1, Note2, Note3, Note4, Note5]
},
{
count: 1,
items: [Note1]
},
{
count: 3,
items: [Note1, Note2, Note3]
}
]
Because we always have at least one notification in our group and our ordering prefers Unread and New notifications we can just use the first notification as a sample for rendering.
So to be able to work with these grouped notifications we need a new object:
class NotificationGroup
{
protected $notifications;
protected $realCount;
public function __construct(array $notifications, int $count)
{
$this->notifications = $notifications;
$this->realCount = $count;
}
public function message()
{
return $this->notifications[0]->messageForNotifications($this->notifications, $this->realCount);
}
// forward all other calls to the first notification
public function __call($method, $arguments)
{
return call_user_func_array([$this->notifications[0], $method], $arguments);
}
}
And finally we can actually put most of the stuff together. This is how the get function on the NotificationManager might look like:
public function get(User $user, $limit = 20, $offset = 0) : array
{
$groups = [];
foreach($this->notificationAdapter->get($user->getId(), $limit, $offset) as $group)
{
$groups[] = new NotificationGroup($group['notifications'], $group['count']);
}
return $gorups;
}
And really finally inside a possible controller action:
public function viewNotificationsAction(Request $request)
{
$notificationManager = new NotificationManager;
foreach($notifications = $notificationManager->get($this->getUser()) as $group)
{
echo $group->unread . ' | ' . $group->message() . ' - ' . $group->createdAt() . "\n";
}
// mark them as read
$notificationManager->markRead($notifications);
}
Answer:
Introduce a read/unread variable on the notification. You can then pull only unread notifications by doing ... WHERE status = 'UNREAD' in your sql.
You can't really... you will want to push that notification. What you can do is still aggregate them though by using GROUP BY. You would likely want to group on something unique like a new homework so it might be something like ... GROUP BY homework.id
You can solve the issue with making a NotificationsRead table, containing the ID of the user and the ID of the notification the user wanted to mark as read.
(This way you can keep each students and the teacher separated.)
Then you can join that table to your notification's table and you will know if it should be considered old or new.
geggleto's answer was right about the second part, you can grab the notifications with SELECT *, COUNT(*) AS counter WHERE ... GROUP BY 'type' then you will know how many of the same type you have there and you can prepare the 'userx and 1 other commented on hw' on view.
I'd also suggest you not to store the whole text you want to display, store the required information instead, like: from_id, class_id, type, name and so - this way you can change mechanisms easier later if you need to, and you have to store less.
For those who are looking for a way to not use an app, you can use vanilla PHP and MySQL without using an application. Upon adding a piece of homework, you can add a notification. (yes I know this is open to SQL injection but I'm using regular MySQL for simplicity sake)
SQL for when someone adds homework:
$noti_homework = "INSERT INTO homework(unread, username, recipient, topic) VALUES(true, user_who_added_hw, user_who_receives_notification, homework_name);
Then you can check whether the notification is unread:
$noti_select = "SELECT FROM homework WHERE recipient='".$_SESSION['username']."' AND unread='true'";
$noti_s_result = $conn->query($noti_select);
$noti_s_row = $noti_s_result = $noti_s_result->fetch_assoc();
if ($noti_s_row['unread'] == true) {
}
Finally, you can echo the notification if it's true.
if ($noti_s_row['unread'] == true) {
echo $noti_s_row['username'] . " has sent out the homework " . $noti_s_row['homework'] . ".";
}
The method for liking a comment is pretty similar and in fact a lot easier.
$noti_like = "INSERT INTO notification_like(unread, username, recepient), VALUES(true, user_who_followed, user_who_recieves_notification);
You then just follow the same pattern of echoing the rows like so:
$noti_like = "INSERT INTO notification_like(unread, username, recipient), VALUES(true, user_who_followed, user_who_receives_notification);
$noti_like_select = "SELECT FROM notification_like WHERE recipient='".$_SESSION['username']."' AND unread='true'";
$noti_l_result = $conn->query($noti_like_select);
$noti_l_row = $noti_s_result = $noti_l_result->fetch_assoc();
if ($noti_l_row['unread'] == true) {
echo $noti_l_row['username'] . " has liked your topic!";
}
Then for getting amount of notifications:
$count_like = "SELECT COUNT(*) FROM notification_like WHERE recipient='".$_SESSION['username']."' AND unread='true'";
$num_count = $count_like->fetch_row();
$count_hw = "SELECT COUNT(*) FROM homework WHERE recipient='".$_SESSION['username']."' AND unread='true'";
$num_count_hw = $count_hw->fetch_row();
Using PHP you can echo the two variables, $num_count and $num_count_hw.
$num_count_real = $num_count[0];
$num_count_hw_real = $num_count_hw[0];
echo $num_count_real + $num_count_hw_real;
None of this code is tested FYI. Hope this helped :)
I have one table named as user
USER(Table)
user_id name status_privilege(0=child,1=parent) added_user_id
2 abc 1
13 child_1 0 2
14 child_2 0 2
I want display user_id = 2(parent's) data in all user_id = 14,15 (all child's login). And also I want to display user_id = 14 , 15's data in user_id = 2's data. (Viceversa)
So for that what to do ?
I tried this query.
SELECT *,child.user_id as child_user_id,parent.user_id as parent_user_id
FROM user as parent
INNER JOIN user as child ON parent.user_id = child.user_added_id
WHERE child.user_id = '14'
so I got child_user_id = 14 & parent_user_id = 2
But I want that when I put below query it give me blank result. (changed child.user_id = '2')
SELECT *,child.user_id as child_user_id,parent.user_id as parent_user_id
FROM user as parent
INNER JOIN user as child ON parent.user_id = child.user_added_id
WHERE child.user_id = '2'
So I want is that when I fire query single query then if user is parent than also I want it's child's all data in user_id ='2' means data of 14 & 15 user's. And 2nd user_id's data in all childs.
Note : All the data in other tables are from user_id so is it possible ?
It's a requirement of existing project so I can not change database structure otherwise I can follow MySQL hierarchical of parent child structure.
the answer is based on what i understand from the question is:
you want the full array of child user ids if parent user logged in and only one parent id if child user logged in.
so in php you can derived that via
<?php
$user=array(); // this array will contains the user info
$res=$db->query("select * from user where user_id='$id'"); //$id the user id with which you want to check whether it is parent or child.
if($res->num_rows > 0)
{
$row=$res->fetch_assoc();
if($row['status_privilege']==0)
{
$res_main=$db->query("SELECT *,child.user_id as child_user_id,parent.user_id as parent_user_id FROM user as parent INNER JOIN user as child ON parent.user_id = child.user_added_id WHERE child.user_id = '".$row['user_id']."'");
$user=$res_main->fetch_assoc();
}
else
{
$res_main=$db->query("SELECT * from user where added_user_id='".$row['user_id']."'");
$user=$row;
$user["child_array"]=array();
while($row_child=$res_main->fetch_assoc())
{
array_push($user['child_array'],$row_child['user_id']);
}
}
}
//you can further check that if user is parent or child by using this condition.
if($user['status_privilege']==1)
{
//parent login it also contain the all child user ids
}
else
{
//child login it also contain the parent id as you have done it before.
}
?>
I've tried to query using laravel eloquent where user is following a specific brand.
The problem: How to query listing of brand and let me know if current login user is following the brand?
got 3 tables:
Brand:
Id | name | logo
User:
Id | name | email | password
Followers:
brand_id | user_id
Now i tried to query all brand and inside of the collection i want to add
is_follow = 1 or is_follow = 0
if the user already follow or 0 if not exists.
I'm using fractal so maybe it can be easier to query. but i don't really get it how to query it out with check the user_id first.
Thanks
*Update
I manage to solve it. But i think its a bad practice.
$user_id = Request::get('user_id');
foreach($brands->followers as $value){
$array[] = $value->user_id;
}
if(in_array($user_id, $array)){
$is_follow = 1;
}
You can check if the authenticated User follows a specific Brand with:
$user = Auth::user();
$exists = $user->brands->contains($brand_id);
You can also do it with a raw query which will be better in terms of performance:
$exists = DB::table('user_brand')
->whereBrandId($brand_id)
->whereUserId(Auth::user()->id)
->count() > 0;
I've got various solution from SO to create my first MLM project, but now I got stuck in total down-line count (via recursive function), as I've no prior Idea on this, please anyone help me.
My Database Table structure is as below (table name member):
`member_id | member_name | node_left | node_right
where member's relation is as:
member_id (Id 101)
/\
/ \
node_left(Id 102) node_right(Id 103)
/\ /\
/ \ blank / \blank
(again) blank node_right (104)
...... and so on. The above is just an example
`
Now I need to count total downline of any member. eg: suppose of above example, I want to know total downline of member_id 101
How to create the recursive function to do this which ends in finite loop ?
please give me any Idea..
I'm not sure if you've tried to implement the nested set model here, but the implementation doesn't look right..
With a nested set, the left/right values representing your tree structure would look like this:
member 101 (root): left=1, right=8
member 102: left=2, right=5
member 103: left=3, right=4
member 104: left=6, right=7
Then, counting the childs of member #101 would be as simple as:
SELECT COUNT(*) FROM member WHERE node_left > 1 AND node_right < 8
you can use/create your own customize function from the below code, Just check it out and try to implement for your case.
function Recursive_getsubcategory($parent_id,$cat_group,$intLevel)
{
global $intLevel;
$sql = "select *,".$intLevel." as level from tbl_name where parent_id = '".$parent_id."' ";
$result = mysql_query($sql);
$cat_name = $result->fetch_array_multiple();
if(count($cat_name) > 0)
{
