Wordpress: Is_Child Function

Published in General on April 1st, 2007 8:12 am by Nicholas Roussos

Here’s a handy WordPress function I put together today. It tells you if the current page is a child of another page. I’m using it to show a sub-navigation on a page and its children.

function is_child ($parent) {
global $wp_query;
if ($wp_query->post->post_parent == $parent) {
$return = true;
}
else {
$return = false;
}
return $return;
}

    Could this be used in an if statement to not display child pages?

    ex:

    if(is_child(’parentpageidhere’))

    I’m looking for something that will not display child pages if you are currently on a child page of a specific parent page.

    if you didn’t want to display child pages, you could simply say:

    if (!is_child(’parentpageid’)) {
    //code here
    }

    The key thing is ! (not) tells you to only do the code when is_child returns false.

    No problem Mike. I just realized that this function will only detect direct children and not grandchildren (if that makes sense). Basically, you can have a page that’s a child of a child of a child. Anyway,I might fix that in the future, but it will only complicate it. The function would probably need to be recursive or something …
