When I am using $category->getChildren(); and I am getting empty array? I have children categories defined and I can see them via Admin Panel. Where should I look for the clue? thanks

  • Have you tried getChildrenCategories()? getChildren() should return a string with coma seperated ids, not an array at all.

  • the source code of 1.9.1.0 says that getChildren() returns array but indeed official document from magento says it is string.... anyway it is empty and getChildrenCategories() also returns empty array....

  • Well, at this point I would try and output the $category->getData() via print_r or var_dump and see what's in there for children

  • @user3154108 I am getting following after print_r($category->getData()): Array ( [entity_id] => 30 [entity_type_id] => 3 [attribute_set_id] => 3 [parent_id] => 2 ........ )

ok found the solution.

my $category is of Varien_Data_Tree_Node type and
$category->getChildren() is Varien_Data_Tree_Node_Collection the problem was that in the Magento Config, Maximal Depth was set to 1. That is why I was getting empty collection (Varien_Data_Tree_Node_Collection) for each category and children_count was OK. Changing Maximal Depth variable to 2 solved the problem.

Thanks!
