Custom Query Pagination Cakephp - mysql

Question

I have a custom query in my controller and I would like to implement the custom query pagination I found on cakephp.org but their example is not similar to mine. Can someone please help me paginate this result in my view:
$cars = $this->Car->query(" select Car.id, Car.make, Car.model, Car.year, Car.description, CarImage.thumbnail
from cars Car
inner join car_images CarImage on Car.default_image_id = CarImage.id
where Car.make like '" . $category . "'
order by Car.created DESC
limit 10");
$this->set('cars', $cars);

Answer 1

Implement paginate and paginateCount in your model:
function paginate($conditions, $fields, $order, $limit, $page, $recursive, $extra)
{
return $this->query('SELECT ...');
}
function paginateCount($conditions, $recursive, $extra)
{
return $this->query('SELECT COUNT(.....');
}
Also check out the paginate function in: cake/libs/controller/controller.php

Answer 2

This looks like it should be able to be done without resorting to using custom pagination.
You should set in the following relationships in your models:
Car hasMany (or hasOne) CarImage CarImage belongsTo Car
Then you should be able to get this exact data using the following:
<?php
class CarsController extends AppController {
var $paginate = array('limit'=>'10',
'order'=>'Car.created',
'fields'=>array('Car.model','Car.year','Car.description',
'CarImage.thumbnail'));
function test() {
// not sure where you are getting the where clause, if its from some form
// you'll want to check look in $this->data
$category = "somevalue";
// set the LIKE condition
$conditions = array('Car.make LIKE' => '%'.$category.'%');
// apply the custom conditions to the pagination
$this->set('cars', $this->paginate($conditions);
}
}
?>
For more information on complex find conditions (which can be applied to paginate by passing in an array like I did in the above example): http://book.cakephp.org/view/74/Complex-Find-Conditions

Answer 3

In Cake 3 you can use de the deafult paginator with function find() .
Follow the example:
$query = $this->Car->find()
->select(['Car.id', 'Car.make','Car.model','Car.year','Car.description','CarImage.thumbnail'])
->join([
'table' => 'CarImage',
'alias' => 'CarImage',
'type' => 'INNER',
'conditions' => 'CarImage.id = Car.default_image_id,
])
->where(['Car.make LIKE' => '%$category%'])
->order(['Car.created' => 'DESC'])
->limit(50)
$cars = $this->paginate($query);
$this->set(compact('cars'));
$this->set('_serialize', ['cars']);

mysql limit clause support volume and offset, so 10 results per page....
select * from table limit 0, 10
page 1
select * from table limit 10, 10
page 2
select * from table limit 20, 10
page 3
select * from table limit ($page-1)*$perPage, $perPage
