    Hi,

    I have a form creating a user and it works perfectly, unless you enter the same username or email that already exists. The issue I have is that it doesn’t display an error or anything, it just says updated.

    Is there a way I can make it error if the username or email already exist?

    Thanks in advance!

    Hello,

    You can use this snippet your field.

    // unique User email
add_filter('acf/validate_value/name=registration_email', 'registration_email_validation', 10, 4);
function registration_email_validation($valid, $value, $field, $input){
    
    if(!$valid)
        return $valid;
    
    $exists = email_exists( $value );
    if ( $exists )
        $valid = 'E-mail already exists';
    
    return $valid;
    
}

    You can do the same with username using
    $check = username_exists($generated_username);

    Cheers

    Hello @bengriff64 & @popsantiago,

    Thanks for the report. In fact @popsantiago has written exactly what I was about to answer 🙂

    You can use his snippet to validate those values. Here is documentation for the reference: https://www.advancedcustomfields.com/resources/acf-validate_value/

    Thanks for your help @popsantiago!

    Have a nice day.

    regards.
