    Hello,

    I am trying to have a custom validation for the mail address field. I would like that only subscribers of a special mail domain are allowed to subscribe.

    I have used your code example here:
    https://docs.ultimatemember.com/article/94-apply-custom-validation-to-a-field

    and modified it a bit:

    add_action(‘um_submit_form_errors_hook_’,’um_custom_validate_mail’, 999, 1);

    function um_custom_validate_mail( $args ) {

    global $ultimatemember;

    if( isset( $args[‘user_email’] ) && filter_var($args[‘user_email’], FILTER_VALIDATE_EMAIL) ){

    $explode_array = explode(“@”, $args[‘user_email’]);
    $domain = $explode_array[1];

    if( $domain != “<MAIL_DOMAIN>” ){
    $ultimatemember->form->add_error( ‘user_email’, ‘Your mail address must contain the domain <MAIL_DOMAIN>.’ );
    }
    }
    }
    Also I have set the parameter to um_custom_validate_mail in the form builder field settings under “custom action”.

    I have this error in the webserver log:

    I’d be happy for some info/help..

    Thank you

  • The tutorial that you took this from is out dated. Ultimate Member 2.0 does not use the global variable $ultimatemember. Here is the updated code that should work

    <?php
add_action('um_submit_form_errors_hook_','um_custom_validate_mail', 999, 1);

function um_custom_validate_mail( $args ) {

	if ( isset( $args['user_email'] ) && filter_var($args['v'], FILTER_VALIDATE_EMAIL) ) {

		$explode_array = explode( '@', $args['user_email'] );
		$domain = $explode_array[1];

		if ( $domain != "<MAIL_DOMAIN>" ) {
			UM()->form()->add_error( 'user_email', 'Your mail address must contain the domain <MAIL_DOMAIN>.' );
		}
	}
}

    Very nice! Thank you!

    I tried this by trial and error , and it worked. I couldn’t understand this code proeprly , please someone explain me . 

    add_action('um_custom_field_validation_ff_exist','um_custom_field_validation_ff_exist', 10, 3);
function um_custom_field_validation_ff_exist( $key, $array, $args ) 
{
	global $ultimatemember;  
	
	if ( (isset( $args['username'] ) && username_exists( $args['username'] ) == false && email_exists( $args['username'] ) == false )  ) 
	{
			$ultimatemember->classes['form']->add_error($key, 'No Freedom Fighter account has been found with this username or email');
			//$ultimatemember->classes['form']->add_error($args['username'], __('Enter a valid 8-number serial please') );  
			//$ultimatemember->classes['form']->add_error('ff_exist','No Freedom Fighter account has been found with this email 2');
	}
}

    I iserted this function in function.php of my theme . Then in register form , I put “ff_exist” in custom validation of ” Username or E-mail of Freedom Fighter ” , I found that metakey of this is “username” , hence I had used $args[‘username’] for checking .

    1. But I dont understand what is $key , and $array here ?
    2. why “//$ultimatemember->classes[‘form’]->add_error(‘ff_exist’,’No Freedom Fighter account has been found with this email 2′);” didn’t work it ? why I couldn’t use ” ff_exist ” instead of “$key” ?
