Learning php and I am losing my mind trying to solve this for days now. Please help.
This is a code which goes thought a table COUPON, take data with a condition met, and download it afterwards. In this table COUPON I have USER_ID as number but I want to have a user name also, which is kept in another table USER.
How can I go to another table (USER) and take names (REALNAME) by this USER_ID which is the same in both tables?
if ( $_POST ) {
$team_id = abs(intval($_POST['team_id']));
$consume = $_POST['consume'];
if (!$team_id || !$consume) die('-ERR ERR_NO_DATA');
$condition = array(
'team_id' => $team_id,
'consume' => $consume,
);
$coupons = DB::LimitQuery('coupon', array(
'condition' => $condition,
));
if (!$coupons) die('-ERR ERR_NO_DATA');
$team = Table::Fetch('team', $team_id);
$name = 'coupon_'.date('Ymd');
$kn = array(
'id' => 'ID',
'secret' => 'Password',
'date' => 'Valid',
'consume' => 'Status',
);
$consume = array(
'Y' => 'Used',
'N' => 'Unused',
);
$ecoupons = array();
foreach( $coupons AS $one ) {
$one['id'] = "#{$one['id']}";
$one['consume'] = $consume[$one['consume']];
$one['date'] = date('Y-m-d', $one['expire_time']);
$ecoupons[] = $one;
}
down_xls($ecoupons, $kn, $name);
After this, I want to try to do the same thing using only SQL queries.
You would need to JOIN the tables in the SQL query
SELECT something FROM coupons as coupons JOIN user as user ON coupons.id=user.id
You should use join when you want to retrieve details from two tables.
Join table COUPON and table USER based on user_id . This should yield results you want.

I'm using LIKE query but when specialist_id's order change it say no records found,
if specialist_id array have [1,2,3] in it then all the users with three specialties should be in results regardless of sequence, sequence array may have [3,2,1] or [2,1,3] but the users with these three specialties should be in results, here is my code with LIKE query:
$field = $this->User->find(
'all', array(
'conditions'=>array(
'User.specialist_id LIKE' =>'%'.$value.'%',
'User.role'=>'careproviderRole',
'User.gender'=>$this->request->data['gender'])
)
);
foreach ($field as $key => $value)
{
$field[$key]['Specialist'] = $user;
}
I have also tried with FIND_IN_SET:
$field = $this->User->find(
'all', array(
'conditions' => array(
'User.role' => 'careproviderRole',
'FIND_IN_SET(\''.$this->request->data['specialist_id'].'\', User.specialist_id)')
)
);
When you use LIKE with mask '%some%', it find all results with substring 'some'.
If you need to get some specific set of ids from table (1, 2 or 3), then use sql operator IN.
Example:
SELECT `specialist_id` FROM `User` WHERE `specialist_id` IN (1,2,3);
In your code it will be:
$field = $this->User->find(
'all', array(
'conditions'=>array(
'User.specialist_id' => $arrayOfSpecialistIds,
'User.role'=>'careproviderRole',
'User.gender'=>$this->request->data['gender'])
)
I'm working on a project for PHPBB. I have a problem that I get some $row types. And they have some "id"s from MySQL, But I want theese "id"s by one by.
It's SQL query ;
$sql = $db->sql_build_query('SELECT', array(
'SELECT' => 'u.*, z.friend, z.foe, p.*',
'FROM' => array(
USERS_TABLE => 'u',
POSTS_TABLE => 'p',
),
'LEFT_JOIN' => array(
array(
'FROM' => array(ZEBRA_TABLE => 'z'),
'ON' => 'z.user_id = ' . $user->data['user_id'] . ' AND z.zebra_id = p.poster_id'
)
),
'WHERE' => $db->sql_in_set('p.post_id', $post_list) . '
AND u.user_id = p.poster_id'
));
$result = $db->sql_query($sql);
And then for user_id's
$rowset[$row['post_id']] = array(
'hide_post' => ($row['foe'] && ($view != 'show' || $post_id != $row['post_id'])) ? true : false,
'user_id' => $row['user_id'],
.
.
I logged $row[user_id] for in a topic and it return ;
97777
97778
97779
97783
But I want just first id i mean -> "97777" . So how can i pass just "97777" to a variable?
Dont suggest about sql level because I can't change any SQL command.
Dont suggest about sql level because I can't change any SQL command.
This is the problem though, your PHP is clearly selecting all 9 rows;
Using WHERE user_id = '97777' you will only select the record you want.
Why can you not edit the SQL? aren't you familiar with SQL or is the code your are using your own?
Without any code it is hard to say what you want to do:
reset($row);
$first_key = key($row);
or
reset($rows);
$first_key = key($rows);
Hard to guess without seeing any code.
You can limit your records using LIMIT clause.
SELECT column_name FROM table_name LIMIT 1;
It will return the first record of that table.
I am working on a ecommerce with platform cakephp and using google charts for reports.My requirement is to get all records as per all 12 months, so I have used following code for a single month
Query
SELECT COUNT(*) AS count FROM orderproductmasters AS Orderproductmaster
LEFT JOIN ordermasters AS Ordermaster ON
(Orderproductmaster.ordermaster_id = Ordermaster.id) LEFT JOIN productmasters AS Productmaster ON
(Orderproductmaster.productmaster_id = Productmaster.id)
WHERE Ordermaster.orderstatusmaster_id = 1 AND Month(Orderproductmaster.created) = 8
Code
$this->Orderproductmaster->find('count',
array('conditions'=>array('Ordermaster.orderstatusmaster_id'=>1,'
Month(Orderproductmaster.created)'=>8)));
Since, I need records as per Jan, feb,march and all 12 months...,so for 12 months I am using following code
for($i=1;$i<13;$i++)
{
$orderproductmasters[$i] = $this->Orderproductmaster->find('count',
array('conditions'=>array('Ordermaster.orderstatusmaster_id'=>1,
'Month(Orderproductmaster.created)'=>$i)));
}
So question might be silly, but is it possible to get all months record without using for loop i.e, within a single query.
Thanks in advance
I think , your need can be fulfilled by using cursors in stored procedure. And then using stored procedure to cake-php.
Example on db side is here
$options = array();
$options['fields'] = array('COUNT(Orderproductmaster.id)');
$options['conditions'] = array('Ordermaster.orderstatusmaster_id = 1',
'Month(Orderproductmaster.created) BETWEEN 1 AND 12');
$options['joins'] = array(
array(
'table' => 'ordermasters',
'alias' => 'Ordermaster',
'type' => 'left',
'conditions' => array(
'Orderproductmaster.ordermaster_id = Ordermaster.id'
)
),
array(
'table' => 'productmasters',
'alias' => 'Productmaster',
'type' => 'left',
'conditions' => array(
'Orderproductmaster.productmaster_id = Productmaster.id'
)
)
);
$options['group'] => array('Month(Orderproductmaster.created)');
$this->Orderproductmaster->find('all',$options);
What About something like:
$this->Orderproductmaster->find('count',
array(
'fields'=>'DISTINCT(Month(Orderproductmaster.created)),
'conditions'=>array('Ordermaster.orderstatusmaster_id'=>1,'
Month(Orderproductmaster.created)'=>8)));
I am using codeigniter to produce a left join of two tables, but need to remove the brackets that active record applies to the table name. you know SELECT blah FROM ('some table') I really need these brackets to disappear.
here is my input array:
$retrieve_arr = array(
'table' => 'entries',
'select' => array('entries.entry_id', 'entries.score', 'sc_users.name', 'clients.name'),
'joins' => array(
'clients' => 'entries.client_id = clients.client_id',
'sc_users' => 'entries.sc_user_id = sc_users.sc_user_id'
),
'joinType' => 'left',
'where' => 'null'
);
here is my model:
$retrieve = new Data();
if($get_arr['select'] != 'null')
{
$query = $retrieve->db->select($get_arr['select']);
}
foreach($get_arr['joins'] as $additional => $value)
{
$retrieve->db->join($additional, $value, $get_arr['joinType']);
}
if($get_arr['where'] != 'null')
{
foreach ($get_arr['where'] as $name => $value)
{
$retrieve->db->where($name, $value);
}
}
$query = $retrieve->db->get($get_arr['table']);
$queryData = $query->result_array();
return $queryData;
and here is what my query string:
SELECT `entries`.`entry_id`, `entries`.`score`, `sc_users`.`name`, `clients`.`name` FROM (`entries`) LEFT JOIN `sc_users` ON `entries`.`sc_user_id` = `sc_users`.`sc_user_id` LEFT JOIN `clients` ON `sc_users`.`client_id` = `clients`.`client_id`Array
I have been looking for this for a while so your help is very much appreciated.
If you are referring to the ` backticks, in the Select() portion, use a FALSE as the second parameter (refer to the Users Guide for more info)
I have two tables, User and Company. I have joining them like this:
$table = $this->getDbTable();
$select = $table->select();
$select->setIntegrityCheck( false );
$select->from( array('User'), array( 'id' => 'id',
'name' => 'User.name',
'gender' => 'User.gender',
'Company_id' => 'User.Company_id'
));
$select->join( 'Company', 'Company.id = User.Company_id',
array( 'Company_name' => 'Company.name' ,
'Company_address' => 'Company.address'
));
$rows = $table->fetchAll( $select );
It is working and giving me accurate result. Problem is that I have to mentions column names in above codes. I want to get all columns without mentioning them in above piece of code.
For example I want something like this that get all columns(But it is not providing all column values):
$table = $this->getDbTable();
$select = $table->select();
$select->setIntegrityCheck( false );
$select->from( array('User') );
$select->join( 'Company', 'Company.id = User.Company_id' );
$rows = $table->fetchAll( $select );
Thanks
Leaving away the second parameter to the from call should work: http://framework.zend.com/manual/en/zend.db.select.html#zend.db.select.building.columns
