Drupal 6 How to override theme function defined in module?

Question

I'm using Taxonomy Browser Module and I'm trying to override the following theme function theme_taxonomy_browser_page which is in taxonomy_browser.module. So I wrote the following function in template.php:

function mytheme_taxonomy_browser_page($form) {
    return "Inside";
}

However, it isn't replacing anything with "Inside" on the page. What could I be doing wrong?

I have cleared cache. Please help me.

Answer 1

Which cache have you cleared?

Theme cache is a bit separated, try to submit the theme selections form at /admin/build/themes.

Answer 2

Might be a silly point but it helpss me make sure my code is being called... try using

drupal_set_message('inside');

It often helps me track down typos or misunderstanding of what is going on in my own admittedly limited Drupal development.

Answer 3

Just an observation in case somebody has the same issue as I had: If the theme you're going to override is going to be used for an administration menu you might be in for a surprise to discover that you have an additional template.php file. I had a sub-theme of Zen as the site theme, but I was using Garland for the administration menu which comes with it's own template.php file. Needless to say I tried for hours to override in the Zen sub-theme template.php file with no success.
