CakePHP - 创建一个编辑同一模型的多行的表单 [英] CakePHP - Create a form which edits multiple rows of the same model
问题描述
我试图构建一个由Subjects组成的表单，它属于SubjectGroups。在视觉上，主题在页面上显示在每个主题组的标题下。您可以编辑主题群组或个别主题的名称。
I am trying to build a form that consists of Subjects, which belong to SubjectGroups. Visually, the subjects are shown on the page under headings of each subject group. You will be able to edit the name of a subject group or an individual subject.
如果我给您一个HTML示例：
If I were to give you an example of the HTML:
<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" />

推荐答案
请参阅保存相关模型数据（特别是Company hasMany帐户示例）。你应该可以通过循环你的数据来实现这一点：
See the documentation for Saving Related Model Data (specifically the numeric-syntax used in the "Company hasMany Account" example). You should be able to achieve this by looping over your data:
$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，您只需执行 $ this-> SubjectGroup-> ; saveAll（$ this-> data）; 。
As for saving, you just do $this->SubjectGroup->saveAll($this->data);.
