PHP/Zend框架2 - 無法動態地生成表

Question

問題

我試圖顯示字段值插入利用Zend框架2和PHP/MySQL的一個表中顯示錶的字段值。鑑於下面的表是動態生成的，我試圖得到如下所示的值。不幸的是，我只能得到單元位置的空值。

問題

我怎樣才能解決這個問題來填充值到他們的小區位置？

代碼

Controller.php這樣

public function summaryAction() 
    { 
     return new ViewModel(array(
      'actionitems' => $this->getActionItemTable()->fetchAll(), 
     )); 
    } 

Table.php

public function fetchAll() 
    { 
     $select = new Select(); 
     $select->from('actionitems', array('*')) 
       ->join('users', 'actionitems.OwnerID = users.UserID', array('OwnerLastName' => new Expression('users.lastName'), 'OwnerFirstName' => new Expression('users.firstName'))); 
     $resultSet = $this->tableGateway->selectWith($select); 
     return $resultSet; 
    } 

index.phtml

 <table class="actionitemsummary"> 
       <tr> 
        <th> 
         Team 
        </th> 
        <th> 
         Item # 
        </th>

        <th> 
         Actions 
        </th> 
       </tr> 
       <?php 
        use Application\Model\ActionItem; 

        /* @var $actionItem ActionItem */ 
       ?> 

       <?php foreach($actionitems as $actionItem): ?> 
       <tr> 
        <td class="team">

        </td> 
        <td class="criticality"> 
         <?php echo $actionItem->criticality; ?> 
        </td> 
        <td class="status <?php echo $actionItem->status; ?> onschedule"> 
         <?php echo $actionItem->status; ?> 
        </td> 
        <td class="assigneddate"> 
         <?php echo $actionItem->assignedDate; ?> 
        </td> 
        <td class="originalduedate"> 
         <?php echo $actionItem->dueDate; ?> 
        </td> 
        <td class="ecd"> 
         <?php echo $actionItem->ecd; ?> 
        </td> 
        <td class="closeddate"> 
         <?php echo $actionItem->closedDate; ?> 
        </td> 
        <td class="owner"> 
         <?php echo $actionItem->ownerID; ?> 
        </td> 
        <td class="actions"> 
         <a href="">View</a> 
        </td> 
       </tr> 
       <?php endforeach; ?> 
      </table>

回答

下面所示的交換陣列的方法需要具有用於將$數據數組元素適當情況下。我修改了從下面的示例開始的所有行，以具有適當的情況。由於ActionItemID是一個字符串，它需要具有ActionItemID的正確大小寫。

答案代碼段（exchangeArray方法中）

$this->actionItemID = (isset($data['ActionItemID'])) ? $data['ActionItemID'] : null; 

我如何到達解...

步驟1）爲了檢測我用的問題以下代碼來查看我的Table類的fetchAll（）中發生了什麼。

/* @var $resultSet ResultSet */ 

$resultSet->getDataSource(); 

var_dump($resultSet->getDataSource()); 

步驟2）然後檢查的var_dump輸出後產生

object(Zend\Db\Adapter\Driver\Pdo\Result)[264] 
    protected 'statementMode' => string 'forward' (length=7) 
    protected 'fetchMode' => int 2 
    protected 'resource' => 
    object(PDOStatement)[265] 
     public 'queryString' => string 'SELECT `actionitems`.*, users.lastName AS `OwnerLastName`, users.firstName AS `OwnerFirstName` FROM `actionitems` INNER JOIN `users` ON `actionitems`.`OwnerID` = `users`.`UserID`' (length=178) 
    protected 'options' => null 
    protected 'currentComplete' => boolean true 
    protected 'currentData' => 
    array (size=22) 
     'ActionItemID' => string '1' (length=1) 
... 

步驟3）我觀察到的最後一行從上面的代碼發信號通知用於ActionItemID適當情況下，其然後導致改變下面的情況。

步驟4）我改變代碼從具有 'actionItemID'

$this->actionItemID = (isset($data['actionItemID'])) ? $data['actionItemID'] : null; 

步驟5）向該（注 'ActionItemID'）

$這 - >的大寫actionItemID =（isset（$ data ['ActionItemID']））？ $ data ['ActionItemID']：null;

結論

由於字符串是大小寫敏感的，必須使用字符串關聯數組內，在這種情況下，特別是在堅持正確的資本。否則，數組元素將不會有值並且不會被設置，並且會導致將null分配給actionItemID和所有其他字段，如問題中所觀察到的。

你需要使用 「的foreach」 來獲得項目訂單DB，這是ResulSet對象的最佳方式：

foreach($resultSet $result){ 
    var_dump($result); 
} 

試試吧。
