cakePHP WHERE IN CLAUSE : Array to String convertion

Question

Hello I want to get all the data from a table that are in the range of those arrays below : //A data sent from AJAX to PHP

$authors = $_POST['authors'];
$articles= $_POST['articles'];

The following cakePHP query is giving me the following errors :

Query:

$this->Mymodel->find('all', array('conditions' => array('Mymodel.name' => array($authors ,$articles)),'order'=>'Mymodel.id DESC'));

Error:

Notice (8): Array to string conversion [CORE/Cake/Model/Datasource/DboSource.php, line 2591]
Database Error

Error: SQLSTATE[42601]: Syntax error: 7 ERROR: syntax error at or near "," LINE 1: ...Mymodel" WHERE "Mymodel"."name" IN (Array, Array) ... ^

What am I doing wrong? I know that if I had an arry as $authors = array('sss','rrr'); it will work so why it does not in my case? Thank you in advance.

I believe your $authors and $articles variables are arrays already.

$this->Mymodel->find('all', array(
  'conditions' => array(
      'Mymodel.name' => array_merge($authors, $articles)
   ),
  'order'=>'Mymodel.id DESC')
);
