如何在CakePHP中的单个页面上创建多个表单？ [英] How can I create multiple forms on a single page in CakePHP?

问题描述

我试图想出一个标准的方法来为索引页上的同一模型创建多个表单。这里有一些细节。

I'm trying to come up with a standard way to create multiple forms for the same model on an index page. Here's a little more detail.

我有一个活页夹列表，每个活页夹都显示一个备忘录。我想要的备注字段可以从索引页面编辑。显然，它不工作只是复制和粘贴的edit_memo动作的视图，如下：

I have a list of binders, each with a memo being displayed. I would like the memo fields to be editable from the index page. Obviously it doesn't work to just copy and paste the view for the edit_memo action, like so:

<?php echo $this->Form->create('Binder');?>
    <fieldset>
        <legend><?php __('Edit Memo'); ?></legend>
    <?php
        echo $this->Form->input('id');
        echo $this->Form->input('memo');
    ?>
    </fieldset>
<?php echo $this->Form->end(__('Submit', true));?>

但这本质上就是我想要做的。

But that's essentially what I'm looking to do. In context, I'm just looping through the binders in the index action and the memos are part of the model.

我尝试改变了。在这种情况下， $ this-> Form-> create（'Binder'）：

$this->Form->create(null,array(
    'id'=>"BinderEditMemo.$i",
    'controller' => 'binders',
    'action' => 'edit_memo',
    'id' => $binder['Binder']['id']
));

但没有运气。备注字段仍然获得常规ID，因此我想我可能需要更改它。当我提交表单它执行操作，但它不保存。 FYI，我已经将id参数路由到我的路由中的操作。

But no luck. The memo field still gets the regular id, so I think I might need to change that as well. When I submit the form it does perform the action, however it does not save. FYI, I have routed the id parameter to the action in my routes.

我确定在索引循环中必须有一个标准的方式来呈现多个表单。任何想法？

I'm sure there has to be a standard way to render multiple forms in the index loop. Any thoughts?

推荐答案

这不是太难，但你不得不依赖Cake的FormHelper魔法。以下作品（或至少为我工作了很多次）：

This isn't too difficult, but you have to rely somewhat less on Cake's FormHelper magic. The following works (or has worked for me on a number of occasions, at least):

<?php
  $baseUrl = array('controller'=>'binders','action'=>'edit');
  foreach ($binders as $_binder) {

    $url = $baseUrl; $url['id'] = $_binder['id'];

    echo $this->Form->create('Binder',array('url'=>$url));
    echo $this->Form->input('Binder.id', array('type'=>'hidden','value'=>$_binder['id']));

    echo $this->Form->input('Binder.memo', array('value'=>$_binder['memo']));

    echo $this->Form->end(__('Submit',true));
  }
?>

我不确定你的数据的结构，所以上面将需要一些调整，但你应该得到的想法。我不知道目的是通过创建假模型等服务。

I'm not exactly sure of the structure of your data, so it the above will require some tweaking, but you should get the idea. I have no idea purpose what is served by creating false models and etc.
