How do I pass information between two controllers, for example:
I have in my database two tables, one of users and another of books, there I select a book that is in the books table, I get your id and I have to update this information in the user table ..
I have two controllers, one of users and one of books, I have to pass the book id to the user controller ..
In the cookbook you can see a method called loadModel() , with it you can use Model of users within your < in> controller books.
$this->loadModel('User');
$users = $this->User->find('all');
If you want to load a specific data from another Model you can use:
$this->loadModel('Livro', 2);
$livro = $this->Livro->read();
If you have correctly made the relationship between the tables and created the Models correctly you can use the following to manipulate the related data
$users = $this->User->Livro->find('all');
$livros = $this->Livro->User->find('all');
To get the user data logged in the cakephp you can use the component Auth section
$this->Auth->user('id');
$this->Session->read('User.id');
