Why Use Code Snippets?
Plugins can slow down your WordPress site, but code snippets let you add custom functionality without extra bloat. By adding small pieces of PHP, CSS, or JavaScript directly, you keep your site fast and organized.
Here’s why snippets are great:
- ✔ Improve site speed (no heavy plugins needed)
- ✔ Keep customizations safe (won’t disappear after theme updates)
- ✔ Easy to manage (enable/disable snippets with one click)
How to Add Code Snippets to WordPress
Step 1: Install the Free “Code Snippets” Plugin
- Go to Plugins > Add New in WordPress
- Search for “Code Snippets” and install the plugin
- Activate it
Now, you’ll see a “Snippets” tab in your dashboard.

'post_status' => 'draft',
'post_type' => $post->post_type
);
$new_post_id = wp_insert_post($new_post);
wp_redirect(admin_url('post.php?action=edit&post=' . $new_post_id));
exit;
