WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I found this code on this site by AshFrame which I added to my functions PHP file and works perfectly to stop one category being displayed on my blog (I have a custom menu so have the category displayed separately)...

add_action('pre_get_posts', 'block_cat_query' );

function block_cat_query() {
    global $wp_query;   
    if( is_home() ) {
        $wp_query->query_vars['cat'] = '-98';
    }
}

My question is how do I format this code to include a second category (in my case -92)? I tried duplicating the code but it generates a PHP error because you can only run the function once I think.

cat takes a comma deliminated list, so '-98,-92'

Thank you Simon - that was straight forward (if you know what you are doing with Wordpress) ... ;-) ... really appreciate your help. Works great. –  Paul Sep 5 '12 at 9:59
    
Pleasure. The codex is always my first port of call.. If I'm using a parameter I take the time to learn about the parameter fully so I can use it moot efficiently.. I only started doing this recently but found that its not actually that time consuming to have a little learning aside while working on a client project (obviously I don't bill them for that 30 seconds ha ha) –  Simon Forster Sep 5 '12 at 10:03
