Cakephp custom query pagination - php

Question

I'm trying to use custom query in Cake then paginate the results with the code below:
$query = $this->Petition->query($sql);
I tried:
$petitions = $this->paginate($query);
and it doesn't work. Is there a way we can do this?
OK I wasn't clear enough: I need to use variable array fetched from custom query on pagination so I can use this for pagination in the view. Is there an easy way of doing this?
Below is my code:
function index() {
if ($this->Session->read('Auth.User.group_id') != 1) {
$commune_id = $this->Session->read('Auth.User.commune_id');
$commune_id = $this->Petition->Commune->findbyId($commune_id);
$commune_id = $this->Petition->Commune->find('all',array('conditions' => array('group' => $commune_id['Commune']['group'])));
$count = count($commune_id);
$i=1;
$sql = "SELECT * FROM `petitions` WHERE `commune_id` = ";
foreach($commune_id as $commune_ids){
if($i==1){
$sql .= $commune_ids['Commune']['id'];
}else{
$sql .= " OR `commune_id` = ".$commune_ids['Commune']['id'];
}
/*if($i != $count){
$this->paginate = array(
'or' => array(
array('Petition.commune_id LIKE' => $commune_ids['Commune']['id'] . ","),
//array('Petition.commune_id LIKE' => "," . $commune_ids['Commune']['id'] . ",")
),
'limit' => 10
);
}*/
$i++;
}
$query = $this->Petition->query($sql);
}
$this->Petition->recursive = 0;
$petitions = $this->paginate();
$this->set('petitions', $petitions);
}

Answer 1

you seriously need to read the pagination part in the cake book:
function index() {
$conditions = array();
if ($this->Auth->user('group_id') != 1) {
$commune_id = $this->Petition->Commune->findById($this->Auth->user('commune_id'));
$conditions['Petition.id'] = $this->Petition->Commune->find('list',array(
'fields'=>array('id','id')
'conditions' => array('group' => $commune_id['Commune']['group'])
));
}
$this->Petition->recursive = 0;
$petitions = $this->paginate('Petition',$conditions);
$this->set('petitions', $petitions);
}
something like that.

Answer 2

this is not how pagination works
you need to fill $this->validate with your conditions etc
and then use $this->paginate() plainly
see
http://book.cakephp.org/view/1232/Controller-Setup
also note the chapter about the custom query part if it is really(!) necessary.
