Select ZF2（2.1方法）填充表单中的选择/下拉元素

我使用Zend Framework 2.1（不是2.0x）方法来填充选择/下拉列表，该列表在以下链接中描述：

虽然我似乎按照他们说的做了，但我收到了一条错误消息，如：

*…：：__construct（）必须是Zend\Db\TableGateway\TableGateway的实例，未给定，在*

这似乎是服务定位器没有正确使用

添加我的字段集的我的表单代码

SupplierFieldset

：

namespace Inventory\Form;
use Zend\Form\Form;
use Inventory\Model;

class ItemForm extends Form
{
    public function init()
    {
        $this->add(array(
                'name' => 'sup_code',
                'type' => 'Inventory\Form\SupplierFieldset'
        ));
    }
}

我的“SupplierFieldset”类：

namespace Inventory\Form;

use Inventory\Model;
use Zend\Form\Element;
use Zend\Form\Fieldset;
use Zend\ServiceManager\ServiceLocatorAwareInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
use Zend\InputFilter\InputFilterProviderInterface;

use Inventory\Model\SupplierTable;
use Inventory\Model\Supplier;

class SupplierFieldset extends Fieldset implements ServiceLocatorAwareInterface
{
    protected $serviceLocator;
    protected $supplierTable;

    public function init()
    {
        parent::__construct('Suppliers Code');
        $this->setLabel('Supplier Code');
        $this->setName('supplier_code');
        $suppliers = $this->getSupplierTable()->fetchAll();

       $select = new Element\Select('supplier_code');
        $options = array();
        foreach ($suppliers as $supplier) {
            $options[$supplier->id] = $supplier->sup_code;
        }
        $select->setValueOptions($options);
    }

    public function setServiceLocator(ServiceLocatorInterface $serviceLocator)
    {
        $this->serviceLocator = $serviceLocator;
    }

    public function getServiceLocator()
    {
        return $this->serviceLocator;
    }

    public function getSupplierTable()
    {
        if (!$this->supplierTable) {
            $sm = $this->getServiceLocator();
            $this->supplierTable = $sm->get('Inventory\Model\SupplierTable');
        }
        return $this->supplierTable;
    }
}

My Module.php getFormElementConfig（）函数：

public function getFormElementConfig()
    {
        return array(
            'factories' => array(
                'SupplierFieldset' => function($sm) {
                    $serviceLocator = $sm->getServiceLocator();
                    $supplierTable = $serviceLocator->get('Inventory\Model\SupplierTable');
                    $fieldset = new SupplierFieldset($supplierTable);
                    return $fieldset;
                 }
            )
        );
    }

My SupplierTable.php模型：

namespace Inventory\Model;

use Zend\Db\TableGateway\TableGateway;

class SupplierTable
{
    protected $tableGateway;

    public function __construct(TableGateway $tableGateway)
    {
        $this->tableGateway = $tableGateway;
    }

    public function fetchAll()
    {
        $resultSet = $this->tableGateway->select();
        return $resultSet;
    }
}

我知道

SupplierTable

模型的构造函数需要

TableGateway$TableGateway

参数。但是，当从

供应商控制器

调用时，此模型工作正常
