The edit method in my controller is successfully being passed a
variable called $categoryID. I'm using the variable to query another
model, which happens successfully and the title field from the model
is displayed in the view via the variable defined here.
App::import('Model','Category');
$cat = new Category();
$category = $cat->field('title', array('id' => $categoryID));
$this->set('category', $category);
My problem arises in the second if statement in the method. By the
time I need the variable to pass through redirect it seems to have
fallen out of scope and I cannot figure out why - the variable appears
to be empty.
Here is the method.
function edit($id = null, $categoryID = null) {
App::import('Model','Category');
$cat = new Category();
$category = $cat->field('title', array('id' => $categoryID));
$this->set('category', $category);
if (!$id && empty($this->data)) {
$this->Session->setFlash(__('Invalid subcategory',
true));
$this->redirect(array('action' => 'index'));
}
if (!empty($this->data)) {
if ($this->Subcategory->save($this->data)) {
$this->Session->setFlash(__('The subcategory
has been saved',
true));
$this->redirect(array(
'controller' => 'subcategories',
'action' => 'index',
$categoryID
));
} else {
$this->Session->setFlash(__('The subcategory
could not be saved.
Please, try again.', true));
}
}
if (empty($this->data)) {
$this->data = $this->Subcategory->read(null, $id);
}
$categories = $this->Subcategory->Category->find('list');
$resources = $this->Subcategory->Resource->find('list');
$this->set(compact('categories', 'resources'));
}
Please be gentle, I've spent a couple of months now reading the
cookbook and a textbook and a series of tutorials - though I am a
newbie! If anyone can offer any assistance and point out why this
might be I'd be very grateful. Thanks in advance.
Adam.
