Question

How can I use Zend’s Zend_Db_Table with many to many relationships with a junction table? Is there any built in method providing this fictionality or have to write simple SQL?

Answer 1

It’s in the documentation: Fetching a Rowset via a Many-to-many Relationship

To fetch a row:

$row->findManyToManyRowset($table,
                           $intersectionTable,
                           [$rule1,
                               [$rule2,
                                   [Zend_Db_Table_Select $select]
                               ]
                           ]);
// Example
$productsRowset = $bug1234->findManyToManyRowset('Products',
                                                 'BugsProducts');
// Here, BugsProducts is the junction table

But, as for a one-to-many relationship, you need to also define the relation in the classes: Defining relationships.
