This don’t work: if( $page->parents() ) { echo 'This is echoed even if there are no parents'; } Any other idea how to check if there are parents?

[image] jenstornell: if( $page->parents() ) { echo ‘This is echoed even if there are no parents’; } What about: if( $page->parents()->count() > 0 ) { echo 'This is echoed even if there are no parents'; }

You could check if the page is in the $pages collection, which is only first level pages (i.e. no parents).

Thanks! I found out a solution: if( $page->parents()->toArray() ) { } …but what do we expect when we write: if( $page->parents() ) { } That it should check if there are parents. The same way to check if a page exists. Maybe I should turn this topic into a suggestion?

It returns a collection of all parents. I agree though that it should return false if there are no parents.

An object can return different things when echo or compare it as a string than using print_r or var_dump. Some kind of magic php I guess. In this case I think that the string output could be improved.

That’s unfortunately not going to work as an object is always considered as “truthy”. I think the best solution is the one proposed by Sonja above. It’s easier to understand and more explicit than checking if the returned array is truthy.

Alright. I don’t fully understand. Is there a difference between these two? Couldn’t they work the same way? if( $page ) { echo 'Page exists. (works)'; } if( $page->parents() ) { echo 'Parents exists. (doesn't work today)'; }

That depends on how you got $page. If via the page() helper: It returns false if the page does not exist. Returning false for empty collections however would break code that expects a collection object.

Yes, that was already suggested above and is probably the best option. As a page method: <?php page::$methods['hasParents'] = function($page) { return $page->parents()->count(); }; Edit: I don’t know why @jenstornell suggests using the toArray() method in his secrets. I’d stick with count(), no…
