Re: How do I add custom validation in controller?

for what its worth, here's some free code to help with the jquery part
(if you still need it)

create the form in your view. Add this jquery script:
var myAjaxSettings = {
type: "POST",
dataType: "json",
success: function(data) {
if (data['success'] == true) {
} else {
alert(data['message']);
}
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert("Internal error: Couldn't submit form");
}
}

$(function() { // same as document.onready
$("#MyForm").submit(function(e) {
e.preventDefault();
myAjaxSettings.url = $("#MyForm").attr('action');
myAjaxSettings.data = $("#MyForm").serialize();
$.ajax(myAjaxSettings);
});
});

Then in the controller do your validation as such:

Configure::write('debug','0');
$this->autoRender = false;
if (!$this->Model->save($this->params['form'])) {
$message = '';
foreach ($this->Album->validationErrors as $e) {
$message .= $e;
}
return json_encode(array(
'success'=>false,
'message'=>$message
));

Thats the just of it. The jquery will intercept your form post and do
an ajax request. Your controller will catch the data from jquery and
try and save it (you may need to tweak it somewhat to get it to work.
Note that the data will be in $this->params['form'] not in $this-
>data). Then if it fails, create a json output to return it back to
your view. The javascript should then alert the user with any
validation errors.
