# WordPress Email TLD Checker

A small WordPress plugin to validate email addresses against valid TLDs.

https://github.com/BoxUk/wordpress-email-tld-checker

# Installation

Installation is handled via Composer.

composer require boxuk/wordpress-email-tld-checker

Make sure you have composer/installers configured to install within the plugins dir.

Activate the plugin.

wp plugin activate wordpress-email-tld-checker

Or via the plugins section of the admin UI.

# Usage

Once the plugin is activated, an email validation (is_email()) will now check that the TLD (the .com bit for example) is valid according to the official IANA database.

# Troubleshooting

The plugin is designed to be installed with Composer and assumes you are including somewhere the autoloader that comes with composer, if you're not then you may run into some issues. The easiest way to resolve is to include the autolaod.php from composer, but failing that you may be able to manually require the following files:

$vendor_dir . '/symfony/polyfill-intl-idn/Idn.php'
$vendor_dir . '/symfony/polyfill-intl-idn/bootstrap.php'
$vendor_dir . '/arubacao/tld-checker/src/RootZoneDatabase.php'
$vendor_dir . '/arubacao/tld-checker/src/Validator.php'
