Category Tabs with Subs

Hi Guys,

 

I am using the Category Tabs with Subs contribution and am having problems with it.

 

My site has 2 levels of categories, main and sub.

 

I noticed if the main category ID is only 1 digit long the sub catgory strip displays the sub categories. However I noticed on some main categories that I clicked on (that DO have subcategories) didn't display the sub categories. I then looked further (head banging) to see if I could find out why SOME main categories displayed the sub categories while others didn't.

 

First I looked in the admin to double check the categories and yes ALL main categories have sub-categories (only 1 level deep) and all sub-catgeories have products (no main categories do BTW).

 

I then looked at the categories_tab.php file to see if I could debug it. I think I have foudbn the pub but don't know how to solve it.

 

Firstly the oub is with main categories that have an ID greater than 1 digit in length (ie.21, 25 etc), these are the problem main categories. Categies with an ID of 1 digit length work OK!

 

Looking at the code I could see that somehow a 2 digit ID (for teh main categories) was being referenced as ONLY by the first digit of the id (ie.25 was being referenced as 2). This problem occurs where the code on line 230 (see below) calls 

$id[0][0

.

 

When doing an echo of the value for the $id[0][0] for 1 digit length categories ids it is fine, but for 2 digit length categories ids it is only returning the first digit of the category ID.

 

The complete (unmodified) code for the category sub with tabs can be seen below. Can any of you out there spot where or why in teh below code the 2 digit categoy IDs are getting trimmed to 1 digit? (I added a comment next to the line that is returning the wrong category id for 2+ digit length category IDs).

Any help with this would be appreciated. :D

Ohh yeah of the code supplied in my last post, only the code below the :

<!-- subcategories //-->

..is probably of interest.

 

Again thanks, hope someone can help.
