am trying to get all the categories on my wordpress as a heirarchial multidimensional array of objects of type category. There are 2 functions in wordpress that kind of do what I want, but not exactly :
1) get_categories() - This one does return an array of category objects, which is great, but then the array is a flat one, where there is no differentiation between which category is a parent or which one is a child.
2) wp_list_categories() - which can return the categories with the herarchy intact, but problem is that the return value is html, and I need the categories to still be objects.
For example, if I had the following 3 trees as my parent-less categories :
/*
tree_stump
tree1
branch1
tree2
branch2
twig2
leaves2
flowers2
fruits2
*/
I am trying to get a return value which could be something like:
$cat_tree=array( 1=>$tree_stump,2=>array(1=>$tree1,2=>$branch1),3=>array(1=>$tree2,2=>array(1=>$branch2,2=>array($twig2,$leaves2,$flowers2,$fruits2 ) ) ) );
where each member of the multi dim array is still an object, and in all the child arrays, the first one is the parent of the rest of the members. I guess this would need some kinda recursive stuff - the stuff that gives me jitters !
Not sure if I made sense, please do let me know if I need to be more clear.. Thanks for reading.
