Select element from other table on the form zf2 - php

Question

i have 2 table with ManyToOne relation on the database between client and sale and i want to select the id_client on the Sale Form . for that o used that .
SaleForm :
public function __construct(ClientTable $table)
{
parent::__construct('vente');
$this->setAttribute('method', 'post');
$this->clientTable = $table;
$this->add(array(
'name' => 'id',
'attributes' => array(
'type' => 'hidden',
),
));
$this->add(
array(
'name' => 'id_client',
'type' => 'Select',
'attributes' => array(
'id' => 'id_client'
),
'options' => array(
'label' => 'Catégory',
'value_options' => $this->getClientOptions(),
'empty_option' => '--- Sélectionnez une categorie---'
),
)
);
public function getClientOptions()
{
$data = $this->clientTable->fetchAll()->toArray();
$selectData = array();
foreach ($data as $key => $selectOption) {
$selectData[$selectOption["id"]] = $selectOption["nom_client"];
}
return $selectData;
}
}
SaleController:
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Caisse\Model\Sale;
use Caisse\Form\SaleForm;
class SaleController extends AbstractActionController
{
protected $saleTable;
protected $clientTable;
public function addAction()
{
$form = new SaleForm($this->clientTable);
$form->get('submit')->setValue('Ajouter');
$request = $this->getRequest();
if ($request->isPost()) {
$vente = new Sale();
$form->setInputFilter($sale->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$vente->exchangeArray($form->getData());
$this->getSaleTable()->saveSale($sale);
return $this->redirect()->toRoute('sale');
}
}
return array('form' => $form);
}
}
But every Time i had this issue:
Catchable fatal error: Argument 1 passed to
Caisse\Form\SaleForm::__construct() must be an instance of
Admin\Model\ClientTable, null given.
Is this the good method to do it, any reference for same example will be welcome.
Thank you

Answer 1

Inside your controller, function addAction, you never set the variable clientTable maybe you forgot to initialize it.
Like this
public function addAction()
{
$this->clientTable = $this->getServiceLocator()->get('Client\Model\ClientTable');
$form = new SaleForm($this->clientTable);
// ...
}
About
public function getClientOptions()
{
$data = $this->clientTable->fetchAll();
$selectData = array();
foreach ($data as $row) {
$selectData[$row->id] = $row->nom_client;
}
return $selectData;
}
