Re: Form Helper Automatically Inserting the ID of the Node?

This happens when you have $this->data['ModelAlias']['id'] set in your
$this->data. If the id is present the helper assumes you're
preforming an edit and as such appends the ID to the url as that is
the default baked behavior (to receive an ID on edit/delete). To
turn this off, make sure to unset $this->data['ModelAlias']['id'] in
your controller if you get a fail.

Example:

function some_action(){
if(!empty($this->data)){
if($this->Model->save($this->data)){
//Hurray, do something like redirect.
}
else{
/*Boo, we had a validation error, unset the id so the form-
>create() doesn't append it to the url, we'll manually add it via a
hidden field instead.*/
unset($this->data['Model']['id']);
}
}
}

I've had to use this trick many times as I don't like passing IDs in
the URL, I prefer to POST them in the data array, but if there is a
validation error all of a sudden the form helper wants to "Help" and
add the id onto the end of the action url.

I hope this helps,
Nick
