- You need to do session read and array merge for this, like
$this->Session->write('products', am($this->Session->read('products'),
array($this->data['Products']['id'])));
Also check if products are in session before doing array merge, like
if ($this->Session->check('products')) {
$this->Session->write('products', am($this->Session->read('products'),
array($this->data['Products']['id'])));
} else {
$this->Session->write('products', array($this->data['Products']['id']));
}
