You could force your PHP to respond with an error header, but I
personally don't think that is a very good practice.
What I've done in the past is have the PHP script return a JSON
response that would look something like:
In the case of no validation errors:
{'valid':'true'}
In the case of validation errors:
{'valid':'false', 'error_msg': 'your validation errors here'}
Then you'd have:
$.ajax({
type: "POST",
url: "script.php",
dataType: 'json',
data: {
...........
},
success:
function(t) {
if (t.valid) {
.... show the result of successful ajax call
}
else {
.... show the result of t.error_msg
}
},
error:
function() {
.... show the result of a failure : server timeout
etc.
}
});
}
Just an idea ;)
