Question

I have a Doctrine_Collection object that was created with code that looks something like.

$collection = Doctrine_Query::create()
->from('FooBazBar')
->where('widget_id = ?',$some_var)
->execute();

Short of writing it down somewhere, is it possible to to retrieve the where clause that was used to create the collection?

That is, I want to be able to so something like

$collection->getWhereClauses(); //fake method

And get back the where clause in some form.

A definitive “no, this isn’t exposed via the API” with an explanation is a perfectly reasonable answer here.

Answer 1

No, this isn’t exposed via the API.

More seriously, you can’t retrieve the query that generated the Doctrine_Collection. The easy way to do this is to create a method in your table, like :

//FooTable.php
public function findByWidgetQuery()
{
return $this->createQuery('foo')
  ->where('foo.baz = ?', 'bar');
}

And then you can use getDqlPart() like this :

$where = Doctrine_Core::getTable('Foo')
->findByWidgetQuery()
->getDqlPart('where');

That should give you an array like this one :

array(2) { [0] => string(8) 'widget = ?' [1] => string(10) 'widget = ?' }

Note that it doesn’t return the actual value passed to the where() clause. To do this you need to use Doctrine_Query::getParams() or Doctrine_Query::getFlattenedParams()

You can find everything in the Doctrine API.
