Wordpress Redirection - Functions.php - Exclude Directory-CodePudding

I have the following code inside my functions.php file, to provide a temporary redirect on my entire site (all URLs redirect to the homepage), but exclude the wordpress admin area...

add_action( 'template_redirect', 'wa_redirect_site', 5 );
function wa_redirect_site(){    
    $url = 'https://' . $_SERVER[ 'HTTPS_HOST' ] . $_SERVER[ 'REQUEST_URI' ];
    $current_post_id = url_to_postid( $url );
    if ( ! is_page(  )) { // Excludes page with this ID, and also the WordPress backend
        $id = get_the_ID();
        wp_redirect( 'https://wa-leicester.org.uk/', 302 ); // You can change 301 to 302 if the redirect is temporary
        exit;
    } 
}

So far, so good, BUT, I'm using a page builder called Bricks Builder, from within the Wordpress admin area, and the trouble is, when I create a template and try to then edit that template, it redirects to the homepage.

When editing a template, the URL it tried to access is: .../template/115/?bricks=run

Which gives me an ID, but I think I need to find a way to exclude the whole /template/ directory.

The code contains a way to exclude page IDs is_page( )) so I have tried to add the directory to that, and I've also tried to see if something exists that replaces that such as: is_directory but I cant seem to find anything about it.

Any help would be massively appreciated!!

You can use is_admin() to determines whether the current request is for an administrative interface page. The default WordPress customiser isn't considered an admin page.

Additionally a lot of plugins are using Ajax requests (@see AJAX in Plugins), so would want to filter that out.

By default, wp_redirect (cross-site) or wp_safe_redirect (locally) are returning a 302.

<?php

add_action( 'template_redirect', function () {  

    /**
     * Determines whether the current request is NOT for an administrative interface page NOR a WordPress Ajax request.
     * Determines whether the query is NOT for the blog homepage NOR for the front page of the site.
     * 
     * is_admin() returns true for Ajax requests, since wp-admin/admin-ajax.php defines the WP_ADMIN constant as true.
     * @see https://developer.wordpress.org/reference/functions/is_admin/#comment-5755
     */
    if ( ! is_admin() && ! wp_doing_ajax() && ! is_home() && ! is_front_page() && ! is_user_logged_in() ) {

        /**
         * Performs a safe (local) redirect, using wp_redirect().
         * 
         * By default the status code is set to 302.
         * @see https://developer.wordpress.org/reference/functions/wp_safe_redirect/#parameters
         */
        wp_safe_redirect( home_url() );

        exit;

    };

} );
