How to use block_editor_no_javascript_message filter in WordPress

Let’s dive into the fascinating world of WordPress hooks, specifically the block_editor_no_javascript_message filter. This hook is all about customizing the message shown in the block editor when JavaScript is turned off in the browser. Integrating this into your WordPress site is straightforward, and I’ll show you how!

First things first, to use this filter, register it using add_filter. You can place this code in the functions.php of your active theme or in a custom WordPress plugin. We at WePlugins, always suggest creating a custom WordPress plugin for hooks. This way, your modifications stay intact during theme updates.

In the following examples, I’ll demonstrate how to implement this filter.

Example 1: Basic Usage

Here’s a simple implementation where we modify the default message using the filter.

    function weplugins_modify_block_editor_no_javascript_message($message, $post) {
        // Custom message for when JavaScript is disabled
        $message = "Please enable JavaScript to use all features.";
        return $message;
    }
    add_filter("block_editor_no_javascript_message", "weplugins_modify_block_editor_no_javascript_message", 10, 2);
    

Example 2: Conditional Message

In this example, we change the message based on specific post types.

    function weplugins_modify_message_based_on_post_type($message, $post) {
        if ($post->post_type === 'product') {
            $message = "JavaScript is required to edit products.";
        }
        return $message;
    }
    add_filter("block_editor_no_javascript_message", "weplugins_modify_message_based_on_post_type", 10, 2);
    

Example 3: Removing the Filter

If you need to remove the filter, here’s how you can do it.

    remove_filter("block_editor_no_javascript_message", "weplugins_modify_block_editor_no_javascript_message", 10, 2);
