Iterate Doctrine Collection ordered by some field

Question

I need something like this:

        $products = Products::getTable()->find(274);
        foreach ($products->Categories->orderBy(\'title\') as $category         


        

Answer 1

You might add a sort function to Colletion.php :

public function sortBy( $sortFunction )
{
    usort($this->data, $sortFunction);
}  

Sorting a Doctrine_Collection of users by their age would look like this:

class ExampleClass
{

    public static function sortByAge( $a , $b )
    {
         $age_a = $a->age;
         $age_b = $b->age;

         return $age_a == $age_b ? 0 : $age_a > $age_b ? 1 : - 1;
    }    

    public function sortExample()
    {
         $users = User::getTable()->findAll();
         $users ->sortBy('ExampleClass::sortByAge');

         echo "Oldest User:";
         var_dump ( $users->end() );
    }

}
