check what is the field that is empty

[felito]

hi

 

i have this

function check($form) {
	$fields = array("radios", "age", "gender");
	foreach($fields as $field) {
		if(empty($form[$field])) {
			return false;
		}
	}
	return true;
}

$data['livre'] = $val-> check($form);
echo json_encode($data);

}

 

 

how i can in jquery ajax checks if the empty false is radios or age?

success: function(data) {
                	 if (!data.livre ) { //this just check in general. i need to know if is false the radios or age
                  	    $("#msgbox1").fadeTo(200, 0.1, function() {
                         $(this).html('empty radios').addClass('messageboxerror1').fadeTo(900, 1);      
                     	});
                         else if (...) {...}
                 	}
                }

You can either select the form elements with jQuery to check their state, or pass it from the PHP function via JSON.

 

PHP:

$data['radios_empty'] = true;

 

jQuery:

if (data.radios_empty == true) { // radios are empty }

i have much more than radios or age.

 

i think the best option is just

echo ($field)

and with  dataType: "text", check if the text is radios or age.

You could assign each error field to an array.

 

function check($form)
{	
$error = array();

$fields = array("radios", "age", "gender");
foreach($fields as $field)
{
	if (empty($form[$field])) {
		$error[$field] = $field;
	}
}

if (!empty($error)) {
	return null;
} else {
	return $error;
}
}

// if there are errors, $data['livre'] will
// contain an array of the errors
//
// otherwise it will be null
$data['livre'] = $val->check($form);

echo json_encode($data);
