Autofill email with username

Hi @mikesuccess,

Thank you for reaching out to us.

I am sorry, I am a bit confused about what exactly you are looking forward to. Do you need to restrict user registration only to email accounts from a particular domain?

I am afraid this is not possible out of the box. I have pinged our developers to see if we can suggest any workaround. We will update you here once we have feedback on this.

Kind Regards,
Nebu John

Hello @mikesuccess ,

We don’t have a snippet that would provide exactly what you need. However, we have a small code that would only allow emails from your chosen domain:

add_filter( 'forminator_custom_form_submit_errors', function( $submit_errors, $form_id, $field_data_array ){

	$email_field    = 'email-1';
	$allowed_domain = 'thedomain.com';

	$email = isset( $_POST[ $email_field ] ) ? $_POST[ $email_field ] : false;
	if ( ! $email ) {
		return $submit_errors;
	}

	list( $user, $domain ) = explode( '@', $email );

	if ( $domain !== $allowed_domain ) {
	    $submit_errors[][ $email_field ] = __( 'Your email address is not valid' );
	}

	return $submit_errors;
}, 20, 3 );

You can use it as an MU plugin https://premium.wpmudev.org/docs/getting-started/download-wpmu-dev-plugins-themes/#installing-mu-plugins

Hi @mikesuccess

I created a small script for you.

You can use it as a mu-plugin: https://wpmudev.com/docs/using-wordpress/installing-wordpress-plugins/#installing-mu-plugins

https://gist.github.com/patrickfreitasdev/04de40e5af67eefaaeb9815600012e63

To use it:

Make your form render from Ajax: https://wpmudev.com/docs/wpmu-dev-plugins/forminator/#rendering

Update the Script line 17 to match your Form ID, it can be found in the Form URL:

The JavaScript will take the value from a username ( text-1 ) and append it as an email to the Email field, it makes the email be readonly too, but in case you would like to hide the e-mail field you can use a hidden field > custom value and make small changes in the script.

You can also make some extra validations to prevent any special characters or blank spaces.
