How to get all cases linke to Opportunity?

Question

I try to get all cases, linke to an opportunity (for example). 
 I need the information in a LogicHook because i want to link the same cases to another type (in this specific case to a document). 
 I&acute;ve tried a lot, but always unable to fetch the linked Cases. 
 $cases1 = $opportunity->get_linked_beans('opportunities_cases_1', 'aCase');

 $cases2 = $opportunity->get_linked_beans('opportunities_cases', 'aCase');

 if ($opportunity->load_relationship('cases')){
 $caseBeans = $opportunity->cases->getBeans();
 } 
 In this example - $case1 and $case2 is "0" and $caseBeans never reached. 
 What&acute;s the best or correct way to determine all attached/linke cases to a bean? 
 Appreciate any help. Thanks a lot.

Hi, In your example you load the cases from the opportunities_cases relationship but I think, but don't know for sure, that the code on line 5 does the same thing. In any case: I think it is easiest to use the load_relationship methods to retrieve the cases from the 'opportunities_cases_1' and 'opportunities_cases' relationship. (I assume they are no relate fields) I've created a little helper class that helps me with this: load_relationship($relationship)) { $child_beans = $bean->{$relationship}->getBeans(); } return $child_beans; } } with this in mind you can easily to the following:
