Cakephp Multiple Table search in container behaviour - mysql

Question

hello I want to get results from multiple tables using the keyword which user has typed. The problem I am having is I don't know how can I do search on that table which is getting through contain
Here's my query
public function getGigPostBasedOnSearch($keyword){
$this->Behaviors->attach('Containable');
return $this->find('all', array(
'contain' => array(
'User','UserInfo', 'GigPostAndCategory.Category','Location','GigPostAndCalender'
),
'conditions' => array(
'AND' => array(
'GigPost.active' => 1,
'OR' => array(
array('GigPost.title LIKE' => '%'.$keyword.'%'),
array('GigPost.description LIKE' => '%'.$keyword.'%'),
array('Location.location_string LIKE' => '%'.$keyword.'%'),
)
)
//'OrderGigPost.request' => 0
),
'order' => 'GigPost.gig_post_id DESC',
'recursive' => 0
));
}
This query works fine. I want to search keyword in category table also.I want to do something like this
array('Category.cat_name LIKE' => '%'.$keyword.'%')
Please help me how can I search in Category table as well
Thank you
Model GigPost.php
<?php
class GigPost extends AppModel
{
public $useTable = 'gig_post';
public $primaryKey = 'gig_post_id';
public $hasAndBelongsToMany = array(
'Category' =>
array(
'className' => 'Category',
'joinTable' => 'gigpost_category',
'foreignKey' => 'gig_post_id',
'associationForeignKey' => 'cat_id',
'unique' => true,
)
);
public $hasOne = array(
'Location' => array(
'className' => 'Location',
'foreignKey' => 'gig_post_id',
'conditions' => array('GigPost.gig_post_id = Location.gig_post_id')
));
public $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id',
'fields' => array('User.user_id','User.email','User.active')
),
'UserInfo' => array(
'className' => 'UserInfo',
'foreignKey' => 'user_id',
)
);
public function getGigPostBasedOnSearch($keyword){
$this->Behaviors->attach('Containable');
return $this->find('all', array(
'contain' => array(
'User','UserInfo', 'GigPostAndCategory.Category'=>array(
'conditions'=>array(
'OR' => array(
array('Category.cat_name' => '%'.$keyword.'%'),
),
)
),'Location','GigPostAndCalender'
),
'conditions' => array(
'AND' => array(
'GigPost.active' => 1,
'OR' => array(
array('GigPost.title LIKE' => '%'.$keyword.'%'),
array('GigPost.description LIKE' => '%'.$keyword.'%'),
array('Location.location_string LIKE' => '%'.$keyword.'%'),
// array('Category.cat_name LIKE' => '%'.$keyword.'%'),
)
)
//'OrderGigPost.request' => 0
),
'order' => 'GigPost.gig_post_id DESC',
'recursive' => 0
));
}
}

Your issue is that the relationship between GigPost and Category is HABTM, so when you use contain Cake has to do a separate query to retrieve the related categories as there is not a one-on-one association. To get round this you need to manually perform a join rather than contain the categories:-
$this->find('all', array(
'contain' => array(
'User', 'UserInfo', 'GigPostAndCategory.Category', 'Location', 'GigPostAndCalender'
),
'joins' => array(
array(
'table' => 'gigpost_category',
'alias' => 'GigPostCategory',
'type' => 'INNER',
'conditions' => 'GigPost.id = GigPostCategory.gig_post_id'
),
array(
'table' => 'categories',
'alias' => 'Category',
'type' => 'INNER',
'conditions' => 'Category.id = GigPostCategory.cat_id'
)
),
'conditions' => array(
'AND' => array(
'GigPost.active' => 1,
'OR' => array(
array('GigPost.title LIKE' => '%'.$keyword.'%'),
array('GigPost.description LIKE' => '%'.$keyword.'%'),
array('Location.location_string LIKE' => '%'.$keyword.'%'),
array('Category.cat_name LIKE' => '%'.$keyword.'%'),
)
)
),
'order' => 'GigPost.gig_post_id DESC',
'group' => 'GigPost.id',
'recursive' => 0
));
This ensures that the categories will be included with the data returned by the primary query.
You will probably need to modify the joins array a bit as you don't appear to be using Cake naming conventions for your table so I am not sure what you have named things. However, this should put you on the right track.
