Email address confirmation

Hi @iritherman

I hope you’re fine today!

Currently there’s no “out of the box” e-mail confirmation like this but it can be added with a small bit of custom code. This should do the trick:

https://gist.githubusercontent.com/adczk/409dba81b8131e21660a39e15f5f5d21/raw/eca09822037d14ba94ac5e5cc515c1d539071fb0/forminator-compare-email-fields.php

To add it to the site you’d need to add it as an MU plugin:

– create an empty file with a .php extension (e.g. “forminator-compare-mails.php”)
– copy and paste that code into it
– in these lines

if( $arr['name'] == 'email-1' ) $email1 = $arr['value'];
if( $arr['name'] == 'email-2' ) $email2 = $arr['value'];

replace email-1 and email-2 with your e-mail fields IDs (without brackets)

`in this line of the code

$submit_errors[]['email-2'] = 'The email addresses must match!';

you should replace email-2 also with ID (without brackets) of one of the e-mail fields of the form (the one you want error to show up) and you can customize error message too.

– and finally – save the file and upload it to the “/wp-content/mu-plugins” folder of your site’s WordPress installation

It should work out of the box.

Best regards,
Adam

Hello @iritherman ,

Please try this code snippet:

<?php 

/************************************
*
* Forminator - compare two e-mail fields to confirm; if different, issue error
*
* by adamcz/WPMU DEV
* Tested with Forminator 1.15.12
*
* Use as MU plugin
*
* Adjust fields' IDs if needed to match your form
*
*********************************/

add_filter( 'forminator_custom_form_submit_errors', 'check_form_data', 99, 3 );
function check_form_data( $submit_errors, $form_id, $field_data_array ) {

	$email1 = $email2 = '';

	foreach( $field_data_array as $arr ) {

		if( $arr['name'] == 'email-1' ) $email1 = $arr['value'];
		if( $arr['name'] == 'email-2' ) $email2 = $arr['value'];

		if( '' != $email1 && '' != $email2 ) break;
	}

	if( $email1 != $email2 ) {
		$submit_errors[]['email-2'] = 'The email addresses must match!';
	}

	return $submit_errors;
}

add_filter( 'forminator_field_email_markup', function( $html, $id, $required, $placeholder, $value  ) {
	$field_name = 'email-2'; // Replace this by the target confirmation email field.

	$search = 'name="' . $field_name . '"';

	if ( false === strpos( $html, $search ) ) {
		return $html;
	}

	$replace = $search . ' autocomplete="off" oncopy="return false" onpaste="return false" '; 
	$html    = str_ireplace( $search, $replace, $html );
	
	return $html;
}, 10, 5);

kind regards,
