Etou starting now with Cakephp, and I’d like to know how to get the value of a specific field.

For example, I have the name and email fields. How to get the name field value?

PS: I know you have the method $this->data, but he takes all the fields.

My form looks like this:

echo $this->Form->create('Usuario', array('action' => 'get'));
echo $this->Form->input('usuario');
echo $this->Form->input('email');
echo $this->Form->input('senha', array('type' => 'password'));
echo $this->Form->input('ativo');
echo $this->Form->end('Salvar');

    Do you refer to the fields of a form? If it is, it is possible to show us how your form is?

    Or, if it’s not what Paulo Rodrigues said, he wants to get the data from Model?

  • Exact @Paulorodrigues. No matter what field I want to pick up. I just want to know how to pick up the value of a field individually.

It is not clear in which situation you want to take this data. If it is the value of the field after sending the form, this is usually done in the Controller:

$usuario = $this->request->data['NomeDoModel']['usuario'];

If you are from the database, you ask for the model (also from the Controller):

$usuario = $this->NomeDoModel->find('all', array(
    'fields' => 'usuario',
    'conditions' => "id = 1" // por exemplo
));
echo $usuario[0]['NomeDoModel']['usuario'];

In the view itself, if the data has been set in the data from the Controler, you can access directly via:

$this->data['NomeDoModel']['usuario'];

Or pass any variable. For example, inside your controller, action index:

function index() {
    this->set(array('dado' => 'bla bla bla'));
}

// e na view:
echo $dado;

  • I managed, using the name of my controller following the name of the field.
