Can I disable right sidebar when on a cat page which has subcats?

I would like my right hand side bar to NOT show up when you are on a category page which lists sub categories.

I currently am able to hide the sidebox on the index page using:

 if ($this_is_home_page == true) { 
$flag_disable_right = true;
$flag_disable_left = false;
}

I have been trying to hide subcats using this code:

// the following IF statement can be duplicated/modified as needed to set additional flags
if ($current_page_base == 'cPath=175') {
     $flag_disable_right = true;
  }

But it's not hiding them.

Any help would be greatly appreciated!

The test code you show will never work. $current_page_base will never be a cPath, and tests for a cPath need to use the numeric part (possibly including underscores) without cPath=.

You can use ($current_page_base == 'index' and $cPath == '175') which will apply only to a listing of category 175. This will not be based on whether it holds categories or products, though.

Do you want to affect only certain categories, or just all categories that have or will have subcats?
Unfortunately subcategory listings and product listings are both 'index' pages.

I would be happy manually setting them for each category page I wish to hide.

Then you can use

if ($current_page_base == 'index' and in_array($cPath, explode(',', '175,189,213,345_7788,666,501'))) {

listing all the cPaths separated by commas, with no spaces.

This is the code I've entered:

if ($current_page_base == 'index' and in_array($cPath, explode(',', '175,174'))) {
     $flag_disable_right = true;
  }

and I have put this code into my tpl_index_default.php in my overrides folder, however the sideboxes are still showing up on the 2 categories I entered (174, and 175)

If I'd like to hide the right column from all, except home page, ezpages and say one category (id 7)
How would I code that?
Thanks

if ($this_is_home_page or ($current_page_base == 'page') or ($current_page_base == 'index' and $cPath == '7')) {
  //show right col
} else {
   $flag_disable_right = true;
}

Terrific thanks :D
