Question

As in the question is there any way in find() method to use a MySQL

WHERE...IN 

condition. Eg.:

SELECT * FROM `table` WHERE `id` IN (1,2,3);

Answer 1

Yes, just use conditions => array (field => array(values) ) like this

$conditions = array ( 'Model.field' => array (1,2,3,4) );

$this->Model->find('all', array('conditions' =>$conditions) );

This will do a WHERE condition like this

SELECT ....
FROM ...
WHERE "Model".field IN (1,2,3,4);
