I hope somebody can help, this is driving me crazy!
I have a simply recursive PHP function for getting all parents to any given parent for a list of categories. You simply pass it the parent category ID for any given category and it will recursively get all the parents further up the tree.
function getParentCategoriesById($parent_category_id,array $parents = []){
if(empty($parent_category_id)) {
return [];
}
$parents[] = $parent_category_id;
$parent_category = DB::builder()->table('product_categories')->find($parent_category_id);
if(!empty($parent_category->parent)) {
getParentCategoriesById($parent_category->parent,$parents);
}
return $parents;}
Let's say category id=100 has 2 parents (33->37), if I dump the $parents array just before the return, the results are:
Array
(
[0] => 33
[1] => 37
)
Array
(
[0] => 33
)
The first array returned is the correct result, but I don't understand how the function is re-running and then instead returning only the first parent.
