I want to remove the right column in all category pages: tutorial didn't work for me

I am sorry if this has been answered, but I couldn't find my situation in the forums.

I want to remove the right column in all category pages, so I followed the tutorial in the faq section, here is the url to that:

https://www.zen-cart.com/tutorials/index.php?article=233

This is the code I put in the proper place in the file:

if (in_array($cPath,explode(",",'3,8')) ) {
$flag_disable_right = true;
$flag_disable_left = false;
}

Because I am following a guide to create a custom template I am using my 'magic' template and uploaded the file to:

/includes/templates/magic/common

Nothing happened on the category pages. Is the file in the wrong place, or the wrong code?

Please help, I know its some simple stupid oversight.

I think I have a better question:

In the code above I am mainly confused about the following yellow section:

if (in_array($cPath,explode(",",'3,8')) ) {
$flag_disable_right = true;
$flag_disable_left = true;
}

This is the portion which tells zen cart where to turn off the flags(which really means columns, right?) but why is this saying '3,8' and not category or something like that. Please let me know if there is a guide or thread that refers to these codes which allow easy reference for what things are called.

Thanks

The 3 and 8 reference your category id's, you need to change these to the id numbers next to your categories in **admin - Catalog - Categories/Products
**

Hi

I am using seo urls and have added the category to the file however the right hand column still displays, i've cross checked the category id and it is correct but is still showing, any ideas (the right colum doesnt show on the product info pages so i know this file is working as it should)

if (in_array($current_page_base,explode(",",'product_info,7')) ) {
$flag_disable_right = true;

Any ideas? I feel that displaying the same columns on every page is poor for SEO due to duplicate content.

Thanks!!

$cPath is not related to $current_page_base - you need a double if test in this case:```php
if (in_array($current_page_base,explode(",",'product_info')) or in_array($cPath,explode(",",'7')) ) {
$flag_disable_right = true;
}

Thank you Glen, you are a star that worked a treat.
