Applying code in Wordpress functions.php to only one category

Question

Is there a way to limit the following code that I've added to my functions.php file so that it only applies to a single wordpress category?

<?php remove_filter('the_content', 'wpautop'); ?>

I tried this, but it didn't seem to work:

<?php if (in_category('work')) { remove_filter('the_content', 'wpautop'); } ?>

I should also add that I solved this problem by placing the code directly in the specific category template, but I'd prefer to keep the filter in my functions file.

Thanks!

I believe you will want to hook into the pre_get_posts action. It fires right after the query string is parsed. Some but not all of the conditionals are set up. You can test if in_category() is one of them, but I don't think it matters. Why? Glad you asked.

The hook is going to pass you the query object, which has the property category_name. All you have to do is check if it has your category and if so fire your filter. Something like this:

function ns_function_name($wpq){
    if($wpq->category_name == 'work'){
        remove_filter('the_content', 'wpautop');
    }
}
add_action( 'pre_get_posts', 'ns_function_name' );

This is totally untested. But since you seem to know what you are doing, it should be enough to put you on the right path.
