I want my plugin to recognize post's categories before post is loaded. i wrote this code but it works in category page not in post's page with the category is specified from me.

function checkUser() {
    if(is_category('programming')){//it doesn't work when post with "programming" category is being displayed
            echo "Bingo!";
        include_once ('TEMPLATEPATH/get-messages.php');
        exit();
    }
} 
add_action('template_redirect', 'checkUser');

is_single() is intend to work with post types, not categories.

To check for category you should use is_category('programming').

Note that is_category works on category archives, not on single view.

So, if you want to check in the current is a single view and has the category 'programming' you need the has_term tag:

if( is_single() && has_term('programming', 'category', get_queried_object()) ) {
  include_once ('TEMPLATEPATH/get-messages.php');
  exit();
}

See is_single, is_category and has_term on Codex.

Also have a look on how conditional tags works in WP.

  • Oh sorry I've forgotten I wrote is_category('programming') but it works when i click on programming category not in post with 'programming' catgory. (let me edit my question) – user1695063 Sep 7 '13 at 6:14
  • for example I've a 'Qt' post with 'programming'category and with this code it will be displayed when you click on it – user1695063 Sep 7 '13 at 6:18
