I have a function that gets the number of unpublished records from a table (which works fine). However now I want to get the total number of unpublished occurances in multiple tables. I figure I can do a foreach loop using the $tables = array('projects', 'testimonials') .etc. then add together their respective results to get total number and return that? However I am not sure how to do this, this kindof loop is a bit outside my abilities.
function publishCount($table) {
$sql = mysql_query("SELECT COUNT(*) AS nb FROM ".$table." WHERE published='0' OR published=''") or die(mysql_error());
$result = mysql_result($sql, 0);
if (!$result == 0) { echo 'Awaiting to be published <span class="badge badge-important">'.$result.'</span>'; }
else { echo 'Awaiting to be published <span class="badge badge-inverse">'.$result.'</span>'; }
}
You should edit your function this way:
function publishCount($table) {
$sql = mysql_query("SELECT COUNT(*) AS nb FROM ".$table." WHERE published='0' OR published=''") or die(mysql_error());
$result = mysql_result($sql, 0);
return $result;
}
So you can then do a loop through your $tables list:
$tables = array('projects', 'testimonials', [...]);
$nbResults = 0;
foreach($tables as $table) {
$nbResults += publishCount($table);
}
if($nbResults == 0) {
// ...
} else {
// ...
}

I have a question
Let say we have this 2 tables in our database
first table : category_lists
second table: data_category
so if list_data_id is equal to 1 meaning that it has 2 data if you look at data_category table which is 6 and 7
Now what I want is to query from category_list table so that 6 and 7 will echo Car Wreckers and Cash For Cars.
This is what my code looks like:
below is my controller:
public function index($listing_name)
{
$this->load->view('layouts/head_layout_seo');
$this->load->view('layouts/head_layout');
$data['main_view'] = 'listings/main_view';
$data['listing_data'] = $this->Listing_model->get_detail_listing($listing_name);
$list_id = $data['listing_data']->list_data_id; // this is what I get list_data_id is equal to 1
$data['category_ads'] = $this->Ads_model->get_ads($list_id); // this is what you need to look
$this->load->view('layouts/main', $data);
$this->load->view('layouts/footer_layout');
}
below is my model:
public function get_ads($list_id)
{
$this->db->where('list_data_id', $list_id);
$query = $this->db->get('data_category');
$query = $query->result();
//return $query;
if (count($query) > 0) {
for ($i=0; $i < count($query); $i++) {
foreach ($query as $value) {
$this->db->where('category_lists_id', $value->category_lists_id);
$querys = $this->db->get('category_lists');
//print_r($query);
return $querys->result();
}
}
}
}
below is my view:
foreach ($category_ads as $value) {
<p><?php echo $value->categories; ?></p> }
with the code above I get only 1 data which is Car Wreckers as you can see from the table, it supposes to show 2 data Car Wreckers and Cash For Cars
Can anyone help me with this?
Thank You
Try this, in your model so no need to call DB two times and no need to loop
public function get_ads($list_id)
{
$this->db->select('cl.category_lists_id,cl.categories');
$this->db->from('category_lists cl');
$this->db->join('data_category dc','cl.category_lists_id = dc.category_lists_id');
$this->db->where('dc.list_data_id',$list_id);
$query = $this->db->get();
if($query->num_rows() > 0){
return $query->result();
}else{
return array();
}
}
I have two lists of check boxes. I am checking which check box is selected and based on that I am trying to get an array.
Let's say the two lists are size which have small, medium, large boxes checked and the other one is color which have red, green, blue boxes checked. The array should look something like:
array[['small', 'medium', 'large']['red', 'green', 'blue']]
But I am getting this:
array[["small"],["medium"],["large"]] [["red"],["green"],["blue"]]
This is the code:
$counter = 0;
$attributes_list = [];
foreach($features_cuts_list as $k => $features_cut) {
$inner_counter = 0;
if ($features_cut["selectedid"] != "") {
$attributes_list[$counter] = [];
$title_to_get = $features_cut["features_cuts_id"];
/* Gets the name of the box that is checked */
$query = "SELECT title FROM features_cuts_translations WHERE lang = '$lang' AND features_cuts_id = '$title_to_get' LIMIT 1;";
$result = mysql_query($query) or die("Cannot query");
$attribute_name = mysql_fetch_row($result);
foreach ($attribute_name as $q) {
array_push($attributes_list[$counter], $q);
}
$counter++;
} else {
}
}
EDIT:
This is the deceleration process for $features_cuts_list:
function getListValuesSql($sql){
global $link; //Database connection
$data=array();
$subData{0}=array();
$res=mysql_query($sql,$link);
if(mysql_num_rows($res)>0){
$i=0;
while($row=mysql_fetch_array($res)){
for($j=0;$j<mysql_num_fields($res);$j++){
$field=mysql_field_name($res, $j);
$subData{$i}[$field]=$row[$field];
}
$data[$i]=$subData{$i};
$i++;
}
return $data;
}else{
return 0;
}
}
$feature_id = $feature["features_id"];
$features_cuts_list = $data->getListValuesSql("
SELECT DISTINCT fct.*, fc.sort, fc.inner_id, fc.price,
fcp.features_cuts_id AS selectedid, IFNULL(fcpv.price,fc.price)
AS price, fcpv.sku
FROM `features_cuts` as fc
JOIN `features_cuts_translations` as fct ON fct.features_cuts_id=fc.id
LEFT JOIN `features_cuts_product_values` as fcpv ON fc.id=fcpv.features_cuts_id AND fcpv.product_id='$pageid'
LEFT JOIN `features_cuts_products` as fcp ON fc.id=fcp.features_cuts_id AND fcp.product_id='$pageid'
WHERE fc.features_id='$feature_id' AND fct.lang='$lang'
Order by fc.sort
");
Hopes this is helpful
From reading your code I think you have unnecessarily provided the $counter variable.Try this modified code:
$attributes_list = [];
foreach($features_cuts_list as $k => $features_cut) {
$inner_counter = 0;
if ($features_cut["selectedid"] != "") {
$title_to_get = $features_cut["features_cuts_id"];
/* Gets the name of the box that is checked */
$query = "SELECT title FROM features_cuts_translations WHERE lang = '$lang' AND features_cuts_id = '$title_to_get' LIMIT 1;";
$result = mysql_query($query) or die("Cannot query");
$attribute_name = mysql_fetch_row($result);
foreach ($attribute_name as $q) {
array_push($attributes_list, $q);
}
$counter++;
} else {
}
}
If not completely, it will mostly solve your issue.
Let me know what the result are , after running this piece of code.
Below is my PHP code. I'm tying to retrieve values from a database and round them to the nearest 10 (upwards only). All the values in the database in this column are integers.
<?PHP
#$Teach_ID = $_POST['txtteachID'];
#$Class_ID = $_POST['txtclass'];
#$BookingDate = $_POST['txtbookingdate'];
#$BookingPeriod = $_POST['txtperiod'];
require_once('../BookingSystem/DBconnect.php');
$capacity = 'SELECT ClassSize FROM classes WHERE ClassID = 1';
$result = $dbh->query($capacity);
$result = (int)$result;
function ceiling($number, $significance = 1)
{
return ( is_numeric($number) && is_numeric($significance) ) ? (ceil($number/$significance)*$significance) : false;
}
}
if ($result->num_rows > 0) {
echo ceiling($result, 10);
}
?>
Error Description
Am I missing something obvious?
You need to loop through your $result variable, which is a mysqli_result object, to get its different entries.
Use mysqli_fetch_assoc to get the values, which will end in something like this :
$capacity = 'SELECT ClassSize FROM classes WHERE ClassID = 1';
$result = $dbh->query($capacity);
function ceiling($number, $significance = 1)
{
return ( is_numeric($number) && is_numeric($significance) ) ? (ceil($number/$significance)*$significance) : false;
}
}
while ($row = $result->fetch_assoc()) {
// if ($result->num_rows > 0) { /* I think this condition is not needed anymore */
$value = intval($row['ClassSize'], 10); // will convert the string from database to an int in base 10
echo ceiling($value, 10); /* I suppose you wanted to use the ClassSize key since it's the one you query */
// }
}
You can't do this $result = (int)$result;. You have to irritate over each row and then extract the data.
One of my sites frequently has more than 1000 concurrent visitors and just for consistency I want to add a thousands separator to the display so it shows like 1,000.
My initial thought was just to add number_format before the variable holding the guest count but this stops the counter working for some reason.
The function in helper.php counting the guests looks like this:
// show online count
static function getOnlineCount() {
$db = JFactory::getDbo();
// calculate number of guests and users
$result = array();
$user_array = 0;
$guest_array = 0;
$query = $db->getQuery(true);
$query->select('guest, usertype, client_id');
$query->from('#__session');
$query->where('client_id = 0');
$db->setQuery($query);
$sessions = (array) $db->loadObjectList();
if (count($sessions)) {
foreach ($sessions as $session) {
// if guest increase guest count by 1
if ($session->guest == 1 && !$session->usertype) {
$guest_array ++;
}
// if member increase member count by 1
if ($session->guest == 0) {
$user_array ++;
}
}
}
$result['user'] = $user_array;
$result['guest'] = $guest_array;
return $result;
}
And in the template the data is displayed using the following:
<?php if ($showmode == 0 || $showmode == 2) : ?>
<?php $guest = JText::plural('MOD_WHOSONLINE_GUESTS', $count['guest']); ?>
<?php $member = JText::plural('MOD_WHOSONLINE_MEMBERS', $count['user']); ?>
<p><?php echo JText::sprintf('MOD_WHOSONLINE_WE_HAVE', $guest, $member); ?></p>
Where do I put the number_format so the separator is added please?
does this not work?
$guest = JText::plural('MOD_WHOSONLINE_GUESTS',number_format($count['guest'],0,'.',','));
Let's say I have these two database tables:
blog comments
------- ----------
blog_id comment_id
title blog_id
content comment
Now I'd like to run through the 3 latest blog entries and display the title, content and the number of comments made on that entry.
For that, I created a Blog_model:
function get_entries($n)
{
if ($n < 1) {$n = 1;}
$this->db->order_by("blog_id", "desc");
$q = $this->db->get('blog', $n);
if($q->num_rows() > 0)
{
foreach ($q->result() as $row)
{
$data[] = $row;
}
return $data;
}
}
The model is loaded in the controller and passed on to the view:
$this->load->model('Blog_model');
$data['blog_rows'] = $this->Blog_model->get_entries(3);
$this->load->view('blog_view');
That gives me the three latest blog entries. I can now loop through the rows and display the content in the view like this:
<?php foreach ($blog_rows as $row): ?>
<h2><?=$row->title;?></h2>
12>
<p><?=$row->content;?></p>
<?php endforeach; ?>
So far so good. But now the tricky part:
I'd like to display the number of comments associated with the displayed blog entry. How would I accomplish that, adhering to the CodeIgniter practices?
Here are two proposals for the model method: the first does a query for each blod row, while the second does an unique query wich is faster. the second query is not tested.
Model 1
function get_entries($n)
{
if ($n < 1) {$n = 1;}
$this->db->order_by("blog_id", "desc");
$q = $this->db->get('blog', $n);
if($q->num_rows() > 0)
{
foreach ($q->result() as $row)
{
$data[] = $row;
}
return $data;
}
foreach($data AS &$blog_e)
{
$q = "SELECT COUNT(*) AS count FROM comments WHERE blog_id = ?";
$query = $this->db->query($q,array($blog_e->blog_id);
$ncomments = $query->result_array();
$blog_e->n_comments = $ncomments[0]['count'];
}
}
Model 2
function get_entries($n)
{
if ($n < 1) {$n = 1;}
$q = "SELECT blog.blog_id,title,content,COUNT(comment_id) AS n_comments
FROM blog JOIN comments ON blog.blog_id = comments.blog_id
GROUP BY blog.blog_id,title,content
ORDER BY blog.blog_id DESC
LIMIT 0,?"
$query = $this->db->query($q,array($n));
if($query->num_rows() > 0)
{
foreach ($q->result() as $row)
{
$data[] = $row;
}
return $data;
}
}
View
<?php foreach ($blog_rows as $row): ?>
<h2><?=$row->title;?></h2>
<?=$row->n_comments?>>
<p><?=$row->content;?></p>
<?php endforeach; ?>
