Question

我正在尝试构建一个由Subjects组成的表单，这些表单属于SubjectGroups。在视觉上，主题显示在每个主题组的标题下的页面上。您将能够编辑主题组或个别主题的名称。

如果我给你一个HTML的例子：

<div class="heading">
    <input type="text" value="Subject Group 1" />
</div>
<input type="text" value="Subject 1" />
<input type="text" value="Subject 2" />
<input type="text" value="Subject 3" />

<div class="heading">
    <input type="text" value="Subject Group 2" />
</div>
<input type="text" value="Subject 4" />
<input type="text" value="Subject 5" />
<input type="text" value="Subject 6" />

...

如何使用Cake的FormHelper构建表单，这样我可以像这样更新多行？
如何验证和更新SubjectGroup和Subject模型？
如何处理每个模型的许多实例（主题1，主题2等）？

Answer 1

请参阅Saving Related Model Data 的文档（特别是“Company hasMany Account”示例中使用的数字语法）。您应该能够通过循环数据来实现这一目标：

$i = $j = 0;
foreach ($subjectGroups as $subjectGroup):
    echo $this->Form->input('SubjectGroup.' . $i . '.id');
    echo $this->Form->input('SubjectGroup.' . $i . '.name');
    foreach ($subjectGroup['Subject'] as $subject):
        echo $this->Form->input('Subject.' . $j . '.id');
        echo $this->Form->input('Subject.' . $j . '.name');
        $j++;
    endforeach;
    $i++;
endforeach;

至于保存，你只需$this->SubjectGroup->saveAll($this->data);。

<div class="heading">
<?php echo $form->input('SubjectGroup.subjectgroup',array('value'=>'subjectgroup 1'));?>    
</div>
<?php echo $form->input('Subject.subject',array('value'=>'subject 1'));?>
<?php echo $form->input('Subject.subject',array('value'=>'subject 2'));?>
<?php echo $form->input('Subject.subject',array('value'=>'subject 3'));?>
<div class="heading">
   <?php echo $form->input('SubjectGroup.subjectgroup',array('value'=>'subjectgroup 2'));?>  
</div>
<?php echo $form->input('Subject.subject',array('value'=>'subject 4'));?>
<?php echo $form->input('Subject.subject',array('value'=>'subject 5'));?>
<?php echo $form->input('Subject.subject',array('value'=>'subject 6'));?>
......
in controller
<?php 
$subjctgroup = $this->data['SubjectGroup'];
$subject = $this->data['Subject'];
$this->User->set( $user );
$this->Contractor->set( $subject );
   if ($this->Subject->validates() && $this->SubjectGroup->validates())
   {
    .......//your code for save the data
   }
   else
   {
        $this->validateErrors($this->Subject);
        $this->validateErrors($this->SubjectGroup);
        $this->render();
   }
   ?>
