Hi

My problem has a more easy solution not involving javascript validation code.
In /hooks/reservas.php

function Reservas_before_insert(&$data, $memberInfo, &$args) {
		
		/* PHP VALIDATE SITE & DATE BEFORE INSERT THE RECORD
		$idSitio = intval($data['Sitio']);	
		$enFecha = $data['Fecha'];
		
		$nSitios = sqlValue("SELECT COUNT(*) FROM Reservas WHERE Sitio ='{$idSitio}' AND Fecha='{$enFecha}'");
				
		if ($nSitios > 0) {
			error_message('SITE RESERVED FOR THIS DATE!', false);
			return false;
		}
		return TRUE;
	}

Works fine, but the message "SITE RESERVED ..." never shows. Instead ...

error_message() is an AppGini function, as far I know.
How can I show this warning to the user

Try this:

Code: Select all

$args['error_message'] = 'SITE RESERVED FOR THIS DATE!';

This can be used as of AppGini 5.90 and above. See https://bigprof.com/appgini/help/advanc ... ore_insert

It worked fine! Thanks a lot!

Is there a AppGini function to show a modal window to the user and have them press an OK button?
Or should it be done as a separate html page?

confirm() Javascript function is the easiest way. And it should be compatible with all browsers and OS's.
