3,040 free snippets from the WPIDE team and the community. Copy the code, or add any snippet to your site in one click with WPIDE.
Send a Webhook When a Post Is Published
Posts a small JSON payload (ID, title, link, author and date) to a URL of your choice whenever a post goes live, to trigger a static site build, a Zapier flow or a chat notification.
Send the Visitor's Language to Mailchimp (MC4WP)
Sets Mailchimp's built-in subscriber language for every signup from your site, using the current WordPress, WPML or Polylang language, so Mailchimp can send the right translation of your campaigns.
Sensible Year Range for Gravity Forms Date Drop-Downs
Sets the years offered in Gravity Forms date drop-downs to a range that fits your form, such as the last 100 years for birth dates or the next two years for bookings.
Separate Favicon for the Admin Area
Uses a different browser tab icon in wp-admin than on the public site, so admin tabs are easy to spot among the others.
Separator Block Styles: Gradient and Ornament
Adds a fading gradient line and a centered ornament (✦) style to the Separator block, for more elegant breaks between sections.
Sequential Invoice Numbers for Orders
Gives each paid order its own gap-free invoice number, such as INV-2026-0001, and shows it on the order screen, in emails and in the customer's order details.
Sequential Reference Number Mail Tag for Contact Form 7
Adds a [_wpide_ref] mail tag that gives every Contact Form 7 submission a running reference number like WEB-1042, which you can quote in the subject or autoresponder.
Series Progress for a Category of Lessons (No LMS Needed)
Adds a [wpide_series_progress category="course-1"] shortcode that shows how many posts in a category the reader has marked complete, with a progress bar and checklist.
Series Taxonomy for Multi-Part Posts
Registers a tag-style "Series" taxonomy for posts, so tutorials or stories split across several posts can be grouped and linked.
Serve Media and Static Files From a CDN Domain
Rewrites the URLs of your uploads, theme and plugin files to a CDN or pull-zone domain you set, so images, CSS and JavaScript are delivered from the CDN while pages are still served by your site.
Serve a humans.txt File
Answers /humans.txt with a plain-text file crediting the people and tools behind the site, generated by WordPress so you do not need to upload anything to the server.
Serve a security.txt File
Publishes /.well-known/security.txt so security researchers know how to report a vulnerability on your site responsibly.
Server and Site Info Widget
Adds a dashboard widget with the PHP, database and WordPress versions, memory limit, upload limit and active theme at a glance.
Server-Timing Header for Administrators
Adds a Server-Timing header with PHP time, database query count and peak memory to pages viewed by administrators, so you can read the numbers in your browser's developer tools Network tab.
Service Structured Data for a Services Post Type
Adds Service JSON-LD (name, description, provider and area served) to single service pages, describing what your business offers.
Services Post Type (Hierarchical)
Registers a page-like "Services" post type that supports parent and child services, ideal for agencies and local businesses.
Set About and Contact Page Types in Yoast Schema
Changes the WebPage type in the Yoast SEO graph to AboutPage, ContactPage or another type for the page slugs you choose.
Set JPEG Compression Quality
Changes the quality used when WordPress generates resized JPEG images. Lower values give smaller files; the default is 82.
Set One Admin Color Scheme for Everyone
Applies the same admin color scheme to all users and hides the color picker on the profile screen. Handy for telling staging and production apart.
Set WebP and AVIF Image Quality
Sets the compression quality WordPress uses when it creates WebP and AVIF images, separately from JPEG, so you can trade a little sharpness for much smaller files.
Set a Different Language for Individual Pages
Adds a "Page language" box to the editor so a single post or page written in another language gets the correct lang attribute (and text direction) for screen readers, spell checkers and search engines.
Set the Body Text Size and Line Height
Sets the default font size and line height of body text in a block theme through theme.json, for more comfortable reading on every page.
Set the Default Checkout Country
Pre-selects a billing and shipping country on checkout for new customers, which saves most of your buyers a step.
