[jQuery] Re: How PHP script can return two variables ?

[Eric Garside]

That XML is a lot of unnecessary work. If you're running with PHP5,
simply print on success:

echo json_encode(array('success' => true, message => ''));

or on failure:

echo json_encode(array('success' => false, message => ''));

And for the jQuery bit:

$.post('somurl.php', function (data){
    if (data.success){
        // Code for successful comment post
    } else {
       // Code for failed comment post
    }
}, 'json');
