Having problems with message search?
But that means for each level I have to do a select query, and I
don’t know how many levels are there, it should be unlimited so how do I do
that ??

Hi,
Top most element don't have parent so it's partent_id is 0. Your first query is
Select * from hosp_categories where parent_id = '0'
This will give you the top elements which you can loop and shows in <select.
Once the user select any of the element in Top <select you have to pass it's
id in query string and run the following query to load the child,
select * from hosp_categories where parent_id = '$ID FROM QUERY STRING'
This will give you the list of child of selected which you can easily show in
<select. Same procedure is follow for next level of category. You can go
till n level with this approach.
Thanks
