How can you check if you are in a particular page in the WP Admin section? For example how can I check if I am in the Users > Your Profile page?

Question

I'm building a plugin and I want to add bits of javascript in the admin head but only for certain admin pages. I don't mean pages as in a WordPress page that you create yourself but rather existing admin section pages like 'Your Profile', 'Users', etc. Is there a wp function specifically for this task? I've been looking and I can only find the boolean function is_admin and action hooks but not a boolean function that just checks.

Answer 1

The way to do this is to use the 'admin_enqueue_scripts' hook to en-queue the files you need. This hook will get passed a $hook_suffix that relates to the current page that is loaded:

function my_admin_enqueue($hook_suffix) {
    if($hook_suffix == 'appearance_page_theme-options') {
        wp_enqueue_script('my-theme-settings', get_template_directory_uri() . '/js/theme-settings.js', array('jquery'));
        wp_enqueue_style('my-theme-settings', get_template_directory_uri() . '/styles/theme-settings.css');
        ?>
        <script type="text/javascript">
        //<![CDATA[
        var template_directory = '<?php echo get_template_directory_uri() ?>';
        //]]>
        </script>
        <?php
    }
}
add_action('admin_enqueue_scripts', 'my_admin_enqueue');

Answer 2

There is a global variable in wp-admin called $pagenow which holds name of the current page, ie edit.php, post.php, etc.

You can also check the $_GET request to narrow your location down further, for example:

global $pagenow;
if (( $pagenow == 'post.php' ) && ($_GET['post_type'] == 'page')) {

    // editing a page

    }

if ($pagenow == 'users.php') {

    // user listing page

    }

if ($pagenow == 'profile.php') {

    // editing user profile page

    }

Answer 3

To offer another method.

// When it's the users list, or your editting another users profile
add_action( 'admin_print_scripts-users.php', 'your_enqueue_callback' );

// When you're editting your own profile
add_action( 'admin_print_scripts-profile.php', 'your_enqueue_callback' );

function your_enqueue_callback() {
    wp_enqueue_script( .. YOUR ENQUEUE ARGS .. );
}
