Question

此代码仅更新一行（与数组中第一行匹配的行）：

编辑：显示更多代码！

这是我的看法。它基于一个关联抓取数据库条目（有一个模型“客户”与其他两个模型，程序和用户有一对多的关系。）

<div class="view">
    <h2><?php echo h($program['Program']['title'])?></h1>
    <?php echo $this->Form->create('User', array('action' => 'pushing')); ?>
    <table id="pushTable">
        <tr><th colspan="5">Select the athletes you would like to push this program to:</th></tr>
        <tr>
        <?php $i=0; ?>
        <?php foreach ($clients['Players'] as $player) {?>
            <?php if ($i == 0) {?><tr><?php } ?>
            <td><?php echo $this->Form->checkbox($player['id']) . ' ' . $player['username'];?></td>
            <?php if ($i == 4) {?></tr><?php $i = 0; } else { $i++; } ?>
        <?php } ?>
        </tr>
    </table>
    <?php echo $this->Form->end(__('Push')); ?>
</div>

在我的用户控制器中：

public function pushing() {
    if ($this->request->is('post') || $this->request->is('put')) {
        $athletes = $this->request->data['User'];
        foreach ( $athletes as $player => $flag){
            if ($flag == 0){
                unset($athletes[$player]);
            }
        }
        $this->User->updateAll(
            array('User.data' => "'foo'"),
            array('User.id' => $athletes)
        );
        $this->Session->setFlash(__('Programs were pushed!'));
        }
    }
}

$运动员是从复选框中收集的数组，在我看来没有问题......所以我不确定为什么updateAll不会迭代数组中的每个ID ...

也许它不适用于数据库相关的原因？我正在开发MAMP ...也许数据库没有设置为“原子”的东西（今天只在这里听说过！）。

我之前曾尝试使用foreach循环遍历id，然后在foreach中执行此操作（编辑：更多代码！）

public function pushing() {
    if ($this->request->is('post') || $this->request->is('put')) {
        foreach ($this->request->data['User'] as $player => $flag) {
            if ($flag) {
                $this->User->id = $player; // set ID to player we want to save ($player is id that was suplpied in view to checkbox
                $this->User->saveField('data', 'foo'); // then, push the data!
            }
        }
        $this->Session->setFlash(__('Programs were pushed!'));
    }
    $this->autoRender = false;
    $this->redirect(array('action' => 'index'));                    
}

但是这导致了重定向的奇怪结果。无论我在哪个行动中放置重定向，保存只是想做自己的事情。那个$ this-＆gt; autoRender什么也没做。控制器仍尝试解析为/ push / route

试一试：）

在您看来：

<div class="view">
        <h2><?php echo h($program['Program']['title'])?></h1>
        <?php echo $this->Form->create('User', array('action' => 'pushing')); ?>
        <table id="pushTable">
            <tr><th colspan="5">Select the athletes you would like to push this program to:</th></tr>
            <tr>
            <?php $i=0; ?>
            <?php foreach ($clients['Players'] as $player) {?>
                <?php if ($i == 0) {?><tr><?php } ?>
                <td><?php echo $this->Form->input('Player.' . $player['id']. '.id', array('type' => 'checkbox', 'value' => $player['id'])) . ' ' . $player['username'];?></td>
                <?php if ($i == 4) {?></tr><?php $i = 0; } else { $i++; } ?>
            <?php } ?>
            </tr>
        </table>
        <?php echo $this->Form->end(__('Push')); ?>
    </div>

在您的控制器中：

public function pushing() {
    if ($this->request->is('post') || $this->request->is('put')) {
        $athletes = $this->request->data['Player'];
        $athlete_ids = array();
        foreach($athletes as $a){
            $athlete_ids[$a['id']] = $a['id'];
        }

        $this->User->updateAll(
            array('User.data' => "'foo'"),
            array('User.id' => $athlete_ids)
        );
        $this->Session->setFlash(__('Programs were pushed!'));
        }
    }
}

你必须稍微改变一下代码才能让我工作..

    $contactsids = array();
    foreach($selected as $key => $val){
      if(($val <> '') && ($val <> 0) ) {                  
          $contactsids[$val] = $val;
      }                        
    } 

$this->Contact->updateAll(
  array('Contact.contact_category_id' => $category_id),
  array('Contact.id' => $contactsids)
);

使用ID数组更新CakePHP中的特定行？
