The Settings Pack - Code Snippets

Last Updated Wednesday 17th July 2024

Code Snippets Bundle

The Bundle contains 22 Snippets that improve Performance of your website, and add Admin Controls. You can import them all in one go rather than copying and pasting individually.

You will need the Free Code Snippets Plugin.

Before adding New Snippets

Always take a Backup
Preferably Export a Full Backup
Test on a Staging Site.

Click to download the Bundle OR Scroll down to see each individual snippet and add individually.

1) Unzip the File.

2) Go to WordPress Dashboard > Snippets > Import

3) The snippets will be added in ‘Deactivated’ form so you can manually activate them depending on your choice.

Go to Upload Files, and choose the unzipped file: elementor.code-snippets.json

Click the ‘Upload files and import’

If you are adding the Bundle again after it’s been updated with new snippets, then select the 3rd option to not import any duplicate snippets.

Then go to All Snippets and decide on which Snippets to Activate.

Activate and check one at a time.

This ensures that content is readable and accessible for individuals with moderate visual impairments.</p>

            <p style="font-size: 15px; line-height: 1.2em;">AAA compliance is the highest level of conformance in WCAG 2.1. It requires a contrast ratio of at least 7:1 for normal text (minimum 16px) and 4.5:1 for large text (minimum 24px or 19px bold). Achieving AAA compliance ensures that content is accessible to the widest range of users, including those with significant visual impairments.</p>

Admin - Duplicate Pages and Posts

				
					/**
 * Duplicate WordPress Posts, Pages, and Custom Post Types as Drafts
 *
 * This code snippet enables the duplication of WordPress posts, pages, and all registered custom post types (CPTs).
 * It adds a 'Duplicate' link to the row actions for each item in the admin dashboard. When clicked, this link
 * triggers the duplication of the selected item, creating a new draft with the same content, custom fields,
 * and taxonomies.
 *
 * Functions:
 * 1. `duplicate_post_as_draft`: Handles the duplication process. It copies the post data, including title,
 *    content, excerpt, and custom fields, and creates a new post with a 'draft' status. It also maintains
 *    the taxonomy terms (like categories and tags) from the original post.
 * 2. `duplicate_post_link`: Adds the 'Duplicate' action link to the WordPress admin interface for each post,
 *    page, and custom post type. This link uses WordPress's built-in nonce functionality for security.
 * 3. `apply_duplicate_post_link_to_cpts`: Dynamically applies the duplicate post link function to all public
 *    post types, ensuring the 'Duplicate' link appears for any custom post types registered on the site.
 *
