Hi, I am not sure this is what you want or some else... You can design the table like this so it will be faster to search. And make the subcategory as linked to category. Means the foreign key. +--------------------+------------------+------+-----+------------------ ---+----------------+ | Field | Type | Null | Key | Default | Extra | +--------------------+------------------+------+-----+------------------ ---+----------------+ | categoryid | int(11) | NO | PRI | NULL | auto_increment | | categoryname | varchar(50) | NO | UNI | NULL | | +-----------------+-------------+------+-----+---------------------+---- ------------+ | Field | Type | Null | Key | Default | Extra | +-----------------+-------------+------+-----+---------------------+---- ------------+ | subcategoryid | int(11) | NO | PRI | NULL | auto_increment | | categoryid | int(11) | NO | MUL | NULL | | | subcategoryname | varchar(50) | NO | | NULL | | Then while search you can make a query with join and search the things efficiently. ____________ 10x, | Ankur Dave | http://ullu.wordpress.com -----Original Message----- From: Tamkhane, Pravin [mailto:ptamkhane@xxxxxxxxx] Sent: Tuesday, November 07, 2006 7:38 PM To: php-db@xxxxxxxxxxxxx Subject: category management using MySQL and PHP Hi All, I am working on small web project based on PHP & MySQL where user is looking for items in certain categories and he specifies the category in search box, the search result should return all items from that category & sub-categories of it. I thought of defining a unique identifier to each category and use them in search but it may work well only for base categories, for hierarchical/sub categories I doubt it will make it simple. Any hints on how can I solve this? Any pointers would be greatly helpful.
