Can anyone help me modify the tree form so that it shows a count() of the
items in the directories as part of the actual tree menu?
I have a std db' named , Classifieds tree, in php4+mysql db, I have grabbed
the produced code below to show that all is basically std, but itisnt set to
use custom code in the project.
In my Project this tree form is linked in CC to an "ads_categories" mysql
table, my classifieds are in an "ads_listings" table
How do i introduce a mysql count for how many I would think i need something
like this
"select count(*) from ads_listings where ad_id=$category_id" ?
Thanks
Steven

Hi Steven,
I used the following bit of code in an ASP app I did.
I put this in the Custom Show event of the Tree form:
SetVar "Category", GetValueHTML(rs,"name") & " (" & dlookup("ads",
"count(*)","category_id = " & GetValue(rs,"category_id")) & " ads)"
Let me know if you want some help translating it to PHP.
Cheers.
Chris
