what is stored in $args on form submit?

what variables are actually passed to:

add_action('um_submit_form_errors_hook', 'validate_venue', 99,1);
function validate_venue( $args ){}

the $args array?

I am trying to have a single validation check multiple conditions and then post the correct errors on the inputs.

I have it working for venue name, but now verifying its a unique address is making me struggle…

global $ultimatemember;
	global $wpdb;

		if ( isset( $args['venue-name'] ) ){
			$venueName = $args["venue-name"];
			$venueAddress = $args["street-address"];
			$venueCity = $args["city"];

			$return_name = $wpdb->get_col($wpdb->prepare("
				SELECT meta_key
				FROM {$wpdb->eo_venuemeta}
				WHERE meta_key = '_venue-name'
				AND meta_value = %s
				", $venueName ));

			$return_address = $wpdb->get_col($wpdb->prepare("
				SELECT meta_key
				FROM {$wpdb->eo_venuemeta}
				WHERE (meta_key = '_address' AND meta_value='%s')
				", $venueAddress));

			$return_city = $wpdb->get_col($wpdb->prepare("
				SELECT meta_key
				FROM {$wpdb->eo_venuemeta}
				WHERE (meta_key = '_city' AND meta_value='%s')
				", $venueCity));

		if($return_name) {
			$ultimatemember->form->add_error("venue-name",'This Venue Name '.$venueName.', is already Taken!','ultimatemember');
		}

		if($return_address && $return_city) {

			if($return_address){
				$return_address->form->add_error("street-address",'This Venue Address '.$venueAddress.', is already Taken!','ultimatemember');
			}

			if($return_city){
				$return_address->form->add_error("city", $venueAddress.'in'.$venueCity.', is already Taken!','ultimatemember');
			}
		}

returns an error of
Fatal error: Call to a member function add_error() on a non-object in /home/prymeadmin/public_html/wp-content/themes/bizmo/functions.php on line 168

which I know is associated with: “$return_address->form->add_error(“street-address”

Any ideas?

I split up the returns to make sure I can variably flag whats wrong…

I know I could prolly do it with

WHERE (meta_key = ‘_address’ AND meta_value=’%s’)
AND (meta_key = ‘_city’ AND meta_value=’%s’)

which would be more ideal, but I need to make sure that the errors propagate the correct info first… and that I am actually gathering the correct values from the inputs.

hence the question about the structure of the $args array.
