你好我有一个问题，我不确定我的错误在哪里。我创建了一个名为 Phonebook 的模块，当我想从数据库中获取结果时，我得到一个空白页。
这是我的代码示例：
控制器：
namespace Phonebook\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Phonebook\Model\Phonebook;
class PhonebookController extends AbstractActionController
{
protected $phonebookTable;
/**
* Get Model Table
*/
public function getPhonebookTableGateway()
{
if (!$this->phonebookTable){
$sm = $this->getServiceLocator();
$this->phonebookTable = $sm->get('Phonebook\Model\PhonebookTable');
}
return $this->phonebookTable;
}
/**
* Index Action
*
* @see \Zend\Mvc\Controller\AbstractActionController::indexAction()
*/
public function indexAction()
{
return new ViewModel(array(
'phonebook' => $this->getPhonebookTableGateway()->fetchAll()
));
}
注意： 我没有显示控制器的完整源代码，因为它太大了。
Module.php 服务管理器
namespace Phonebook;
use Phonebook\Model\Phonebook;
use Phonebook\Model\PhonebookTable;
use Zend\Db\ResultSet\ResultSet;
use Zend\Db\TableGateway\TableGateway;
public function getServiceConfig()
{
return array(
'factories' => array(
'Phonebook\Model\PhonebookTable' => function($sm) {
$tableGateway = $sm->get('PhonebookTableGateway');
$table = new PhonebookTable($tableGateway);
return $table;
},
'PhonebookTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Phonebook());
return new TableGateway('phonebook', $dbAdapter, null, $resultSetPrototype);
},
),
);
}
电话簿表
<?php
namespace Phonebook\Model;
// Get Zend Table Gateway
use Zend\Db\TableGateway\TableGateway;
class PhonebookTable
{
protected $tableGateway;
/**
* Constructor
*
* @return Inject Dependency in TableGateway.
*/
public function __construct(TableGateway $tableGateway)
{
$this->tableGateway = $tableGateway;
}
/**
* Fetch all
*
* Method fetch all article from database
*
* @return resource
*/
public function fetchAll()
{
$resultSet = $this->tableGateway->select();
return $resultSet;
}
}
电话簿
<?php
namespace Phonebook\Model;
class Phonebook
{
/**
* Item ID
* @var int
*/
public $id;
/**
* First Name
* @var str
*/
public $firstname;
/**
* Last Name
* @var str
*/
public $lastname;
/**
* Phone
* @var Str
*/
public $phone;
/**
* City
* @var str
*/
public $city;
/**
* Exchange Data
*
* @return array
*/
public function exchangeArray($data)
{
$this->id = (!empty($data['id'])) ? $data['id'] : null;
$this->first_name = (!empty($data['first_name'])) ? $data['first_name'] : null;
$this->last_name = (!empty($data['last_name'])) ? $data['last_name']: null;
$this->phone = (!empty($data['phone'])) ? $data['phone'] : null;
$this->city = (!empty($data['city'])) ? $data['city'] : null;
}
}
看法
<tbody>
<?php foreach ($phonebook as $item) :?>
<tr>
<td> <?php echo $this->escapehtml($item->id);?>
<td> <?php echo $this->escapehtml($item->firstname);?>
<td> <?php echo $this->escapehtml($item->lastname);?>
<td> <?php echo $this->escapehtml($item->phone);?>
<td> <?php echo $this->escapehtml($item->city);?>
</tr>
<?php endforeach;?>
</tbody>
当我从 Controller 中删除服务管理器时，页面成功呈现而没有数据库结果。
