Installation & Setup

Installation requires WordPress 4.5+ and PHP 5.6+. You can install it by searching for "Masks Form Fields" in your WordPress dashboard under Plugins > Add New, or by downloading the ZIP file from WordPress.org and uploading it manually. Setup is beginner-friendly: add a class like class:phone to your Contact Form 7 field tag, and the mask activates automatically. No configuration page is needed.

Support & Community

The plugin's support forum shows 0 open threads and 0 resolved threads over the last 2 months, resulting in a 0% resolution rate. This could indicate that users find the plugin stable enough not to need support, or that the developer is not actively monitoring the forum. The 23 ratings are all five-star, with no one-star reviews, suggesting existing users are satisfied with the functionality as-is.

Given the 10-year age of the plugin and its consistent updates (last on May 23, 2026), the lack of support threads may reflect a mature, bug-free product. For users who need help adding custom masks, the plugin description links to external documentation for the jQuery Mask Plugin. This means you may need to reference that documentation for advanced customizations beyond the built-in patterns.
