Add a user in Cakephp authentication tutorial - cakephp

Question

There is a problem when I write add() function for UsersController.
public function add(){
if ($this->request->is('post')) {
if ($this->User->save($this->request->data)) {
$this->Session->setFlash('The new user has been saved.');
$this->redirect(array('action' => 'test'));
}
}
$this->set('title_for_layout', 'Register');
}
This is add view ctp.
<?php
echo $this->Form->create('User');
echo $this->Form->input('username');
echo $this->Form->input('password');
echo $this->Form->end('Save User');
?>
There's always a internal error when I try to access to users/add. Anyone know how to deal with this problem? Thanks.

Answer 1

Have you tried testing for $this->data instead of $this->request->is('post')? It might not matter, but that's typically the way it is done.
Also, for saving, you should most likely (unless you are setting userid manually) do something like:
$this->User->create();
$this->User->save($this->data);
So your add function should look something like:
public function add(){
if ($this->data) {
$this->User->create();
if ($this->User->save($this->data)) {
$this->Session->setFlash('The new user has been saved.');
$this->redirect(array('action' => 'test'));
}
}
$this->set('title_for_layout', 'Register');
}
And you probably want your view to be something like:
<?php echo $form->create('User', array('action' => 'add')); ?>
<?php echo $form->input("username", array('label' => 'Username')) ?>
<?php echo $form->input("password",array("type"=>"password", 'label' => 'password')) ?>
<?php echo $form->submit('Submit'); ?>
