WPCode – Insert Headers and Footers + Custom Code Snippets – WordPress Code Manager

Introduction

In WordPress development, adding custom code snippets to a website often requires modifying theme files, dealing with functions.php, or using multiple plugins. However, making direct edits can be risky—mistakes can break your site, and updates might overwrite changes.

WPCode (formerly known as Insert Headers and Footers) is a powerful WordPress plugin that makes it easy to add and manage custom code without modifying theme files. Whether you’re inserting Google Analytics, Facebook Pixel, custom JavaScript, CSS, or PHP snippets, WPCode provides a safe and organized way to manage your code.

In this guide, we’ll explore WPCode’s features, how to install and use it, best practices, and how it compares to other custom code plugins.

What is WPCode?

WPCode is an all-in-one code manager for WordPress that allows users to:
✔ Insert scripts into the header, footer, or body without editing theme files.
✔ Run PHP, JavaScript, CSS, HTML, or shortcode snippets.

How to Use WPCode for Different Purposes

1. Adding Google Analytics Tracking Code

• Copy your Google Analytics script from Google Analytics.
• Paste it into WPCode > Header & Footer > Header.
• Save changes.

2. Running a Custom PHP Snippet Without Editing functions.php

• Example: Automatically redirect users after login.

phpCopyEditadd_action('wp_login', 'custom_redirect_after_login');
function custom_redirect_after_login() {
    wp_redirect(home_url());
    exit();
}

• Go to WPCode > Add New Snippet > PHP.
• Paste the code and set it to Auto Insert (Everywhere).

3. Disabling WordPress REST API for Non-Logged-in Users

• Useful for security purposes.

phpCopyEditadd_filter('rest_authentication_errors', function ($result) {
    if (!is_user_logged_in()) {
        return new WP_Error('rest_forbidden', 'REST API is disabled for non-logged-in users.', ['status' => 403]);
    }
    return $result;
});

• Add this as a PHP snippet in WPCode.

4. Injecting Custom CSS Without Editing Theme Files

cssCopyEditbody {
    background-color: #f4f4f4;
}

• Add it as a CSS snippet and set it to Auto Insert (Everywhere).
