Form using dropdown doesn't work on Phalcon - forms

Question

I'm using the framework Phalcon. I'm trying to create a form to get a value (an ID called "idcliente") from a table (in mysql) called cliente, which has 2 columns: "idcliente" and "nombre". With this value I want to update a field (also "idcliente") on another table called Users.
My form is this:
class AsignarclienteForm extends Form{
public function initialize($entity = null, $options = null){
$idcliente = new Select('idcliente',[
Cliente::find(),
"useEmpty" => true,
"emptyText" => "Please select...",
"using" => ["idcliente", "nombre"],
]);
$idcliente->setLabel('ID Cliente');
$idcliente->addValidators(array(
new PresenceOf(array(
'message' => 'idcliente is required'
))
));
$this->add($idcliente);
}
}
And my controller:
public function asignarclienteAction(){
$auth = $this->session->get('auth');
$permiso = $auth['active'];
$id = $auth['id'];
if($permiso!='A'){return $this->forward('servicios/index');}
$form = new AsignarclienteForm;
if ($this->request->isPost()) {
$idcliente = $this->request->getPost('idcliente');
$sql = "UPDATE Users SET idcliente = ?0 WHERE id = ?1";
$this->modelsManager->executeQuery($sql, array(0 => $idcliente, 1 => $id));
return $this->forward('admin/usuarios');
}
$this->view->form = $form;
}
And my view:
<div class="panel-body">
{{ form('admin/asignarcliente/', 'id': 'asignarclienteForm', 'onbeforesubmit': 'return false') }}
<fieldset>
<div class="control-group">
{{ form.label('idcliente', ['class': 'control-label']) }}
<div class="controls">
{{ form.render('idcliente', ['class': 'form-control']) }}
</div>
</div>
<div class="form-actions">
{{ submit_button('Asignar', 'class': 'btn btn-primary', 'onclick': 'return SignUp.validate();') }}
</div>
</fieldset>
</form>
</div>
I got the following error in the web site:
ID Cliente
Catchable fatal error: Object of class Phalcon\Mvc\Model\Resultset\Simple could not be converted to string in C:\xampp\htdocs\OpinionZoom\cache\volt\c%%%%xampp%%htdocs%%opinionzoom%%app%%views%%admin%%asignarcliente.volt.php on line 31
Where line 31 is {{ form.render('idcliente', ['class': 'form-control']) }}
on my view
I haven't found enough documentation of how to create a form with select, despite I have created a lot of forms.
If someone could help me I would appreciate it a lot. Thanks.

Answer 1

Your element definition in your form Asignarclienteform is incorrect.
The first parameter of Select must be a string (the name of your element).
The second parameter takes the options of your select element.
// Select construct parameters
Select(string $name, [object | array $options], [array $attributes])
I moved idcliente out of the array into the first parameter position:
$idcliente = new Select('idcliente', Cliente::find(), [
"useEmpty" => true,
"emptyText" => "Please select...",
"using" => ["idcliente", "nombre"],
]);
