Doctrine & Regular Expression

Question

I have tried to get a products recordset from MySQL with the Doctrine ORM. I have to select a group of records using a regexp where the category field value can contain these values:

categories

12/43/45/101/109

OR

categories

1/12/43/45/101/109

OR

categories

43/45/101/109/12

This is my doctrine code:

$id = 12
$dq = Doctrine_Query::create ()
          -> from ( 'Products p' )
          -> leftJoin("p.ProductsData pd WITH pd.language_id = $locale")
          -> leftJoin("p.ProductsAttributesGroups pag")
          -> where('p.enabled = ?', 1)
          -> andWhere ( "(categories REGEXP \"^$id[\\\]*\" OR " .
                        "categories REGEXP \"^[\\\]$id*\" OR " .
                        "categories REGEXP \"^[\\\]$id[\\\]*)\")" )
          -> orderBy('position asc');

I have the $id variable and I need to select all the records where this $CATID is present. I cannot use a MySQL relationship and/or joins.

Answer 1

The simple solution in my case was this one:

// Get the category selected in the products table where the categories have been written in this way: \\12\\224\\85\\53

$reg1 = "categories like '".$id."/%'";
$reg2 = "categories like '%/".$id."'";
$reg3 = "categories like '%/".$id."/%'";
$dq->andWhere ( "($reg1 OR $reg2 OR $reg3)");
