Hi developers,

I want to make my custom field required on the vendor sign-up page. The field gets red and says it is required when it is not filled and you hit submit.

When the field is filled, it is no longer red. BUT the submit button (apply to be vendor) does not work.. So the vendor can no longer submit the sign-up form. I think the required fields are somehow still blocking the form to be submitted..

Code in my functions.php:

// IBAN field on vendor pro settings page
function store_bankc_details( ){ 
	if ( class_exists( 'WCVendors_Pro' ) ){ 
		$key = '_wcv_custom_settings_bankcname'; 
		$value = get_user_meta( get_current_user_id(), $key, true ); 
		// Bankc Name
		WCVendors_Pro_Form_Helper::input( array(  
			'id' 				=> $key, 
			'label' 			=> __( 'IBAN <small>Required</small>', 'wcvendors-pro' ), 
			'placeholder' 			=> __( 'IBAN 001 0934093', 'wcvendors-pro' ), 
			'desc_tip' 			=> 'true', 
			'description' 			=> __( 'Met het IBAN nummer wordt de gemaakte winst uitbetaald.', 'wcvendors-pro' ), 
			'type' 				=> 'text', 
			'value'				=> $value, 
			'custom_attributes' => array(
				'data-rules' 	=> 'required', 
				'data-error'	=> 'Dit veld is verplicht' , 'wcvendors-pro' ,
				),
			)
		);
	} 
}

function wcv_custom_settings_bankcname_required( $args ) { 
    $args[ 'custom_attributes' ] = array( 
	'data-rules' => 'required', // Change 'required' to '' to make it not required (just remove the word required but keep the single quotes)
	'data-error' => __( 'This field is required.', 'wcvendors-pro' )
	); 
    return $args; 
} 
add_filter( 'wcv_custom_settings_bankcname', 'wcv_custom_settings_bankcname_required' ); 

System report is ok and it is not theme related. Looking for a much appreciated solution!
