Redirect from the dashboard to edit.php if wp_is_mobile() is true

Question

Looking for a way to redirect the user from the dashboard straight to edit.php if wp_is_mobile() is true.

This is what I've tried:

function redirect_if_mobile() {
    $screen = get_current_screen();
    if($screen->base == 'dashboard') {
        if ( wp_is_mobile() ) {
            $url = admin_url( 'edit.php' );
            wp_redirect( $url );
        }
    }
}
add_action( 'admin_menu', 'redirect_if_mobile');

The problem is that get_current_screen() isn't defined in either admin_init or admin_menu (if you hook onto admin_head instead it's too late and headers have already been sent).

Ideas?

Answer 1

The action you're looking for is auth_redirect, which is before the headers but still recognizes $pagenow to tell which page you're on:

add_action('auth_redirect', 'the_mobile_boot');
function the_mobile_boot() {
    global $pagenow;

    if ( $pagenow == 'index.php' && wp_is_mobile() ) {
        header( 'Location: ' . get_admin_url(null, 'edit.php') );
        exit;
    }

}

Alright, found one solution, although not that elegant.

function load_if_mobile() {
    if ( wp_is_mobile() ) {?>
    <script>
        window.location = '/wp-admin/edit.php';
    </script><?php
    }
}
add_action('admin_head-index.php', 'load_if_mobile');
