The answer was actually really simple, I will post here in case it
helps anybody else.
I was trying to over-complicate things and pass a string to the
paginate conditions, when an array was needed. (Now I look back, a
string made no sense at all - but at least I'm learning!)
First step, is to do a find on the data in question (in this case I
used the variable $name), then use the following method to return the
children of the current ID:
// Grab parent id and children id:
$children = $this->Category->children($name['Category']['id']);
Next a new array is created to store the children's ID's:
// Loop through all of the children ID's and populate an array:
foreach ($children as $child) {
$child_array[] = $child['Category']['id'];
}
I then added the current ID to the array:
// Add the current id to the array so current category results are
also included:
$child_array[] = $name['Category']['id'];
It was then just a case of adding the array to the paginate
conditions:
// Now setup paginating with all of the results:
$this->set('category', $this->paginate('Post', array('Category.id' =>
$child_array)));
So in conclusion, this is how I managed to paginate the tree behaviour
to include sub-categories as well. Hopefully this will help somebody
as I couldn't find much on this subject when searching.
