Add a Class to my Body Tag using the Forum Title

  • Rackmire



    I’m trying to build a theme for my BBpress site and I would like to add a class to my body tag that changes depending on where the user is within the forum but only for within a forum area.

    For instance… On my BBpress installation, if I have these forums:

    • Green
    • Red
    • Blue
    • Yellow

    If the user view topics within the ‘Green’ forum/sub-forum it add the classname ‘green’ to the body tag i.e “<body class=”green”>” I would like it to use the Forum’s title that is set. Can somebody help?

    Preferably the code to be in functions.php or header.php / bbpress theme files. I don’t want to hack the bbpress core files.

    I want to do this so I can change the way it looks i.e background colour etc.

    And the Homepage stays the same: <body> (with no classname unelss set within the header.php of the theme file.

    This is what you will need to use to actually add a class to the body class. You could look at getting the post by the get_queried_object(); function in WordPress and then getting the title of that object. After that you could then use the sanitize_title_with_dashes($forum_title); to get a safe class name.

    Please note I haven’t fully tested the code below and i’m not sure the $forum_object->post_title; will work but it get’s you moving in the right direction 🙂

    $forum_object = get_queried_object();
    $forum_title = $forum_object->post_title;
    $forum_class = sanitize_title_with_dashes($forum_title);
    <body <?php body_class($forum_class); ?>>

    Good luck!



    Hi Thanks for your support and fast reply. Much appreciated,

    Do I just paste this code in my header.php file?

    Sorry, this functions seems to return the topic title, not the forum title. I have ‘googled’ around and got this:

    $forum_object = get_queried_object();
    $forum_id = $forum_object->forum_id; // get the forum id, is it right?
    $forum_title = get_forum_name( $topic->forum_id ); // get forum title by id
    $forum_class = sanitize_title_with_dashes($forum_title); //sanitize

    Not working since get_forum_name doesn’t work outside bbpress (inside WordPress header). Any other idea on how get the forum title (not the topic) and use as body class on WordPress? Thank you.

    Edit: sorry, i’ve noticed my mistake since use the title was what Rackmire wanted. I need the inverse: use the parent forum title as class. I’m using a custom page template (forum.php).
