Confirm email field

This guide will show you how to add an email confirmation field so that the form user must enter their email address twice and they must match.

Confirm email address example

Step 1

Add two Email elements to your form, if you haven’t done so already. One for the email address and one for the confirm email address.

Step 2

Add the following code to the theme functions.php file (or create a plugin for it).

add_filter('quform_element_valid_1_4', function ($valid, $value, Quform_Element_Email $element) {    if ($valid && $value != $element->getForm()->getValue('quform_1_3')) {        $element->addError('The email addresses do not match');
        $valid = false;
    }
 
    return $valid;
}, 10, 3);
add_filter('quform_element_valid_1_4', function ($valid, $value, Quform_Element_Email $element) {
    if ($valid && $value != $element->getForm()->getValue('quform_1_3')) {
        $element->addError('The email addresses do not match');
        $valid = false;
    }

    return $valid;
}, 10, 3);
  • On line 1, change 1_4 to the unique ID of your confirm email element
  • On line 2, change 1_3 to the unique ID of your first email element

        $valid = false;
    }
 
    return $valid;
}add_filter('quform_element_valid_1_4', 'my_confirm_email', 10, 3);
function my_confirm_email($valid, $value, Quform_Element_Email $element)
{
    if ($valid && $value != $element->getForm()->getValue('quform_1_3')) {
        $element->addError('The email addresses do not match');
        $valid = false;
    }

    return $valid;
}
add_filter('quform_element_valid_1_4', 'my_confirm_email', 10, 3);
  • On line 3, change 1_3 to the unique ID of your first email element
  • On line 9, change 1_4 to the unique ID of your confirm email element

Further customization

You can hide the submitted value for your email confirm element, because it’s just a duplicate. To do that, go to the settings for the confirm email element, and on the Data tab turn off the options Show in email and Save to database.
