WP-Members Email Validator

A WordPress plugin that adds email validation to WP-Members registration forms.

Features

• Validates email address format using WordPress's built-in is_email() check
• Blocks institutional email domains (.gov, .edu, .org, .mil, .int) — enforces personal email only
• Confirms that the email and confirmation email fields match
• PHP 7.4 compatible (polyfills str_ends_with for PHP < 8)

Requirements

• WordPress 5.0+
• PHP 7.4+
• WP-Members plugin

Installation

1. Upload the wp-members-email-checker folder to /wp-content/plugins/
2. Activate the plugin through the Plugins menu in WordPress
3. No configuration needed — validation runs automatically on WP-Members registration forms

How It Works

Hooks into the wpmem_register_data filter. If any validation fails, returns a WP_Error to WP-Members which displays the error to the user and blocks registration.
