I need your help. I'd be very thankfull if write me this script.I
need a script that displays a list of categories and subcategories
like this:
<select name="category" >
<option value="1">Main</option>
<option value="2">Main > Computers</option>
<option value="4">Main > Computers > Hardware </option>
<option value="8">Main > Computers > Hardware > PC</option>
<option value="7">Main > Computers > Hardware > Mac</option>
<option value="9">Main > Computers > Hardware > Atari</option>
<option value="11">Main > Computers > Hardware > PC > History of
Pc</option>
<option value="">etc... </option>
</select>
The categories and subcategories details are stored in these two
tables in a MySQL database.
-categories : the categories names and ids.
-cat_relations : the relations between categories.It shows which
subcategory belongs to which category.
The belongings between categories can go very deep and the number of
categories is unlimited. This script will create the two tables and
fill them with sample data. All you need to do is to change the four
variables below. You can send me the script back to this email :
yasbergy@yahoo. com and thank you in advance.

to fit your settings
