Select row where field contains certain values was created by Jan van de Laar

Hi All

I've built a component with two tables, one of them is named 'categorie'. I can select more than one. In the database there is a field "categorie" and it contains " 1, 3 ". So this row matches with categories 1 and 3.
Now I want to select the proper rows in my frontend view and I want to use this where clause:

$query->where($db->quoteName('categorie') . ' = 1 ');

But this only works with value 1, when I try value 3 there are no database results. I tried using LIKE but that doen't work either. Can someone please help me with this?

Just found the solution:

// Construct the search term by escaping the user-supplied string and, if required, adding the % wildcard characters manually.

$cat = '%' . $db->escape( $cat, true ) . '%' ;

// Construct the SQL query

$query = 'SELECT * FROM #__table WHERE `categorie` LIKE ' . $db->quote( $db->escape( $cat ), false );
