CakePHP2.0 What is the correct way to access post variables in a CakePHP controller?

Question

I am unsure as to how I access variables that I have posted using ajax in my controller. I though it might be something along the lines of:

$this->request->data['post']['varName'];

I don't think that is the correct way to access the variables I have posted as it doesn't seem to work, so my question is: "What is the correct way to access post variables in a CakePHP controller". For completeness I will include an example jQuery ajax call. If you could refer how to access the data with the example below that would be great

$.ajax({ type: "POST",
         url: "someURL", // Not an actual URL just placeholder for example
         data: {'foo': 5, 'bar': 12},
         success: function()
                  {
                       alert('Post was successful');
                  }
          });

So how would I access foo and bar in a cakePHP controller?

Also if you know where to find this information in the documentation could you please link me to it as I had a hard time finding the information.

Update!

Found the link to the documentation here.

Is $this->request-data['post']['varName']; a typo? If not, then you have a syntax error after the request property where you need a -> .

I think your problem could be solved by using this though:

echo $this->request->data['foo']; // Should print 5
echo $this->request->data['bar']; // Should print 12
