Remote validation

[enber79]

Hi all, anyone knows how to perform remote validation (php) in a textbox?

Thanks

Ok, now I can pass a value via POST to an external PHP, and get response:

Code:

$.extend($.fn.validatebox.defaults.rules, {
	dni: {
		validator: function(value, param){
				$.ajax({
				type: "POST",
				url: 'php/validation.php',
				data: {dni: value},
				success: function(data){
					if (data == '1')
					{
						return true
					}
					else
					{
						return false
					}
				}
			});
		},
		message: 'DNI incorrecto'
	}
});

This return 1 or 0, and If is working as intended, but cannot show error message. Where I can return validation as true or false?

Thanks again.

Please try this 'remote' validator.

Code:

$.extend($.fn.validatebox.defaults.rules, {
	remote:{
		validator: function(value,param){
			var target = this;
			var opts = $(this).validatebox('options');
			var data = {};
			data[param[1]] = value;
			if (!opts.notValidate){
				$.ajax({
					url: param[0],
					dataType: 'text',
					data: data,
					type: 'post',
					success: function(data){
						if (data == 'true'){
							opts.result = true;
						} else {
							opts.result = false;
						}
						opts.notValidate = true;
						$(target).validatebox('validate');
						opts.notValidate = false;
					}
				});
			}
			return opts.result!=undefined ? opts.result : true;
		},
		message:'Please fix this field.'
	}
});

Usage example:

Code:

<input class="easyui-textbox" validType="remote['php/validation.php','q']">

In your 'validation.php' script, you must receive the 'q' parameter value and return 'true' or 'false' to the browser.

Code:

<?php
$q = $_REQUEST['q'];
if (...){
	echo 'true';
} else {
	echo 'false';
}
?>
