What is WDD WordPress plugin development?

WDD WordPress plugin development is WebDevDoer’s practice of building small, focused WordPress plugins that solve one problem well. Eight of them are free to download, each with its own documentation, covering custom code, admin cleanup, security headers, redirect chains, file permissions, post ordering, back-to-top navigation and multilingual switching. Custom plugins for client sites are built the same way.

What is WDD Custom Code Manager?

WDD Custom Code Manager is a WordPress plugin that gives you a centralised, secure place to manage all custom code on your site. Instead of editing functions.php or scattering snippets across theme files, every piece of code lives in a searchable database with its own toggle, scope, priority, and device rules.

Inject any code, anywhere on your site.

Add custom CSS, JavaScript, HTML, and PHP snippets — site-wide or per page — with a professional syntax-highlighted editor, device targeting, and full export/import support. No theme file edits. No FTP. Just code that works.

What is WDD Back To Top?

A transparent, icon-only navigation plugin for WordPress. Scroll visitors back to the top — or straight to the bottom — with two fully independent, pixel-precise buttons.

WDD Back To Top places a fixed arrow button on every page of your site. When a visitor scrolls down past a configurable distance, the button fades in and smoothly scrolls them back to the top when clicked. Everything — colour, size, position, speed — is controlled from a single settings page in the WordPress admin.

What is WDD Admin Cleaner?

Stop unwanted update checks, remove dashboard widget clutter, and hide non-essential admin notices — all from one settings screen. Admin Cleaner gives you one place to control three separate things in wp-admin, each handled by its own dedicated part of the plugin:

Updates:

Fully disable core, plugin, theme, or translation update checks — not just hide the notice about them.

Dashboard:

Remove the Welcome Panel, Activity, Quick Draft, Events & News, Site Health, and At a Glance widgets from the main Dashboard screen.

Admin Notices:

Hide non-critical notices from other plugins and themes, split into plugin-origin, theme-origin, promotional, and review-request categories — while always keeping error notices visible.

What is WDD Drag & Drop Post Order?

A fast, clean drag-and-drop interface to reorder posts, pages, and custom post types — with an optional feature to update publication dates to match the new order.

What this plugin does:

WDD Drag & Drop Post Order gives you a dedicated admin screen to drag posts into whatever order you want. Once you save, your site’s front end will show posts in that exact order — no theme editing, no custom queries, no shortcodes.

What is WDD Header Security Guard?

Manage and control HTTP security headers in WordPress safely — without breaking your themes, plugins, or caching systems like WP Rocket.

WDD Header Security Guard gives you full control over the HTTP security headers your WordPress site sends to browsers. Toggle each header on or off, customise the values, apply ready-made presets, and keep a log of every change — all from a clean admin panel that adds nothing to your frontend.

What is WDD Redirect Chain Fixer?

Everything you need to install, configure, and get the most out of the plugin — from adding your first redirect to auto-fixing chains.

What Is a Redirect Chain?

A redirect chain happens when a visitor trying to reach URL A gets bounced through one or more intermediate URLs before finally landing at the destination. Each hop adds latency, wastes your crawl budget, and weakens the SEO value passed along the chain.

WDD File Permission Reset

A dashboard tool for finding and fixing incorrect WordPress file and folder permissions — the quiet cause behind a lot of broken updates, blank pages after a migration, and “failed to write file” errors.

Every run is broken into small batches, so it stays responsive whether your site has a few hundred files or several hundred thousand. Nothing changes on disk until you explicitly click Reset — and even then, only within the WordPress install itself, never outside it.

What is WDD Polylang Floating Language Switcher?

A floating, mobile-first language switcher widget for Polylang-powered WordPress sites.

This plugin renders a fixed-position button in the corner of the screen. Tapping it opens a dropdown listing every language configured in Polylang, with flags and language names. It’s designed primarily for mobile visitors, though desktop visibility can be turned on in settings.

Everything the widget needs — markup, styles, and behaviour — is self-contained under a single element, #wdd-lang-switcher, so it can be dropped into any theme without affecting existing layouts or styles.

FREQUENTLY ASKED QUESTIONS

WDD WordPress Plugin FAQs

Are the WDD WordPress plugins really free?

Yes. All eight WDD plugins are free to download from this page. There is no account to create and no paywall: download the zip file and install it like any other WordPress plugin.

How do I install a WDD plugin?

Download the plugin zip from its card in the catalog above. In wp-admin, go to Plugins → Add New Plugin → Upload Plugin, choose the zip file, then install and activate it. The options appear on the plugin's own settings page.

Where can I find the documentation?

Each plugin card in the catalog has a Documentation link with step-by-step installation and configuration instructions, so you can read how it works before installing it.

Which WDD plugins are available?

Eight plugins are available: WDD Custom Code Manager, WDD Back to Top, WDD Admin Cleaner, WDD Drag & Drop Post Order, WDD Header Security Guard, WDD Redirect Chain Fixer, WDD File Permission Reset and WDD Polylang Floating Language Switcher.

Do WDD plugins work with any theme or page builder?

They are standalone plugins and do not depend on a specific theme. Plugins that add something visible on the front end, such as Back to Top or the language switcher, may need a quick check against your theme. Each plugin's documentation lists what to expect, and testing on a staging copy first is always a good idea.

How do I update or remove a WDD plugin?

To update, upload the newer zip through Plugins → Add New Plugin → Upload Plugin and choose to replace the current version. To remove a plugin, deactivate it on the Plugins screen and then delete it.

Will a WDD plugin slow down my website?

WDD plugins are lightweight and single-purpose, so each one does a specific job instead of loading a large feature set. As with any plugin, test it on a staging copy first if your site is busy or heavily customised. If speed is a concern, I can also help with WordPress speed optimization.

Can I use more than one WDD plugin on the same site?

Yes. Each plugin solves a separate problem, so they are designed to sit side by side. For example, you can use WDD Admin Cleaner to tidy the dashboard alongside WDD Custom Code Manager to manage your snippets.

Should I back up my site before installing a plugin?

Yes, a backup before installing any plugin is good practice. It matters most for plugins that change how your site behaves at a deeper level, such as WDD Header Security Guard, WDD Redirect Chain Fixer and WDD File Permission Reset.

Do I need Polylang to use the language switcher?

Yes. WDD Polylang Floating Language Switcher is built for WordPress sites that already use Polylang. It adds a floating, mobile-first language switcher on top of the languages you have configured there.

Is it safe to add PHP code with WDD Custom Code Manager?

Custom PHP can break a site if it contains an error, so add snippets one at a time, keep a recent backup and test on staging when you can. Only add code from sources you trust, and use the snippet toggle to switch a snippet off if something goes wrong.

What should I do if something breaks after activating a plugin?

Deactivate the plugin from the Plugins screen. If you cannot reach wp-admin, rename the plugin's folder inside wp-content/plugins using your hosting file manager or FTP, then restore your backup if needed. You can also contact me and I will help you track down the cause.

Can you build a custom WordPress plugin for my site?

Yes. I design and build custom WordPress plugins, from small utilities to integrations and admin tools, using the same lightweight, single-purpose approach as the WDD plugins.

How do I request a custom plugin?

Use the contact page and describe what the plugin should do. I will reply with the scope and the next steps.

How much does custom plugin development cost?

Pricing depends on the features, integrations and testing involved. After reviewing your requirements I provide a clear fixed-price proposal before any work starts.

Can you fix or extend a plugin that is already on my site?

Yes. I can debug conflicts and errors or add missing features to an existing plugin. See the WordPress bug fixing service for details.

What should I include in my custom plugin request?

Describe the problem the plugin should solve, where it should appear on your site, any plugins or services it must work with (for example WooCommerce or Polylang) and any deadline. The clearer the brief, the more accurate the scope and proposal.

Can a custom plugin work with WooCommerce or a multilingual site?

Yes. WooCommerce and multilingual setups can be part of the scope. Mention them in your request so compatibility is planned and tested from the start.
