CakePHP 2.0确定已单击哪个提交按钮 [英] CakePHP 2.0 Determine which submit button has been clicked

问题描述

在CakePHP 1.3中，您可以使用多个提交按钮创建表单：

  echo $ this-> Form->提交（'Submit 1'，array（'name'=>'submit'）; 
 echo $ this-> Form-&提交'）; 
  

并检测控制器中按下哪个提交按钮：

  if（isset（$ this-> params ['form'] ['submit']）&& $ this-& ['form'] ['submit'] ==Submit 1）{
 //第一个按钮点击
} 
   
 
在CakePHP中，未设置$ this-> params ['form']，点击的按钮值不会出现在$ this-> request，$ this - > request-> data，$ this-> params，$ this-> data或$ _POST 。
 
 
 
如何确定点击了哪个按钮在CakePHP 2.0中？
 
 
 
提前感谢。

根据请求，下面是表单的代码：
 <？php echo $ this-> Form - > create（'History'，array（'action'=>'add'））; ？> 
< div class ='submit'> 
<？php 
 echo $ this-> Form-> submit（'Yes'，array（'div'=> false，'name'=>'submit'）） 
 echo $ this-> Form-> submit（'No'，array（'div'=> false，'name'=>'submit'））; 
？> 
< / div> 
<？php echo $ this-> Form-> end（）？> 
  
并且输出形式：
 < form action =/ projects / kings_recruit / trunk / www / histories / addid =HistoryAddFormmethod =postaccept-charset =utf-8> 
< div style =display：none;> 
< input name =_ methodvalue =POSTtype =hidden> 
< / div> 
< div class =submit> 
< input name =submitvalue =Yestype =submit> 
< input name =submitvalue =Notype =submit> 
< / div> 
< / form> 
  
 
 
解决方案
一般来说，为两个提交按钮。 
在$ _POST和$ this-> request-> data 
 
 
中应该有一个submit键我在CakePHP 2.1.1中测试了这个
 
 
 
视图代码：
 <？php echo $ this-> Form-> create（'Message'，array（'action'=>'test'））; 
 //额外的测试输入字段
 echo $ this-> Form-> input（'test'）; 
？> 
 
< div class ='submit'> 
<？php 
 echo $ this-> Form-> submit（'Yes'，array（'div'=> false，'name'=>'submit'）） 
 echo $ this-> Form-> submit（'No'，array（'div'=> false，'name'=>'submit'））; 
？> 
< / div> 
<？php echo $ this-> Form-> end（）？> 
  
在$ this-> request-> data中的控制器中：
  array（
'submit'=>'Yes'，
'Message'=& test'=>'TestFieldTest'
）
）
  
 _POST：
 数组（
'_method'=>'POST'，
'data' > array（
'Message'=> array（
'test'=>'TestFieldTest'
）
），
'submit'=> 'yes'
）
  
您也可以给两个提交不同的名字：
  echo $ this-> Form-> submit（'Yes'，array（'div'=> false，'name' =>'submitY'））; 
 echo $ this-> Form-> submit（'No'，array（'div'=> false，'name'=>'submitN'））这样，你可以在$ _POST或$ this-> request->数据中区分它们，因为它们是不同的：
 
 
 
键将是提交者的名字：
 数组（
'submitY'=>'是'，
'Message'=> array（
'test'=>'foo'
）
）
 
数组'=>'POST'，
'data'=> array（
'Message'=> array（
'test'=>'Bar'
） 
），
'submitY'=>'是'
）
  
然后，要确定按下哪个按钮，您可以使用简单的isset（$ _ POST ['']）或$ this-> request-> data？
 
In CakePHP 1.3 you can create a form with multiple submit buttons:
echo $this->Form->submit('Submit 1', array('name'=>'submit');
echo $this->Form->submit('Submit 2', array('name'=>'submit');
and detect which submit button was pressed in the controller with:
if (isset($this->params['form']['submit']) && $this->params['form']['submit'] == "Submit 1") {
  // first button clicked
}
In CakePHP, $this->params['form'] isn't set and the clicked button value doesn't appear anywhere in $this->request, $this->request->data, $this->params, $this->data or $_POST.

How do I determine which button has been clicked in CakePHP 2.0?

Thanks in advance.

Edit:

As requested, here's the code for the form:
<?php echo $this->Form->create('History', array('action'=>'add')); ?>
<div class='submit'>
<?php 
echo $this->Form->submit('Yes', array('div'=>false, 'name'=>'submit')); 
echo $this->Form->submit('No', array('div'=>false, 'name'=>'submit')); 
?>
</div>
<?php echo $this->Form->end()?>
And the output of the form:
<form action="/projects/kings_recruit/trunk/www/histories/add" id="HistoryAddForm" method="post" accept-charset="utf-8">
  <div style="display:none;">
    <input name="_method" value="POST" type="hidden">
  </div>
  <div class="submit">
    <input name="submit" value="Yes" type="submit">
    <input name="submit" value="No" type="submit">
  </div>
</form>

解决方案
Generally it is a bad practise to use the same name for both submit buttons.
There should be a "submit" key in the $_POST and $this->request->data

I tested this in CakePHP 2.1.1 as shown below:

The view code:
<?php echo $this->Form->create('Message', array('action'=>'test')); 
//  Extra test input field
echo $this->Form->input('test');
?>

<div class='submit'>
<?php 
echo $this->Form->submit('Yes', array('div'=>false, 'name'=>'submit')); 
echo $this->Form->submit('No', array('div'=>false, 'name'=>'submit')); 
?>
</div>
<?php echo $this->Form->end()?>
The in the controller in $this->request->data:
array(
    'submit' => 'Yes',
    'Message' => array(
        'test' => 'TestFieldTest'
    )
)
And in $_POST:
array(
    '_method' => 'POST',
    'data' => array(
        'Message' => array(
            'test' => 'TestFieldTest'
        )
    ),
    'submit' => 'Yes'
)
You can also give the two submits different names:
echo $this->Form->submit('Yes', array('div'=>false, 'name'=>'submitY')); 
echo $this->Form->submit('No', array('div'=>false, 'name'=>'submitN')); 
This way you can differ them in the $_POST or $this->request->data, because the keys will be the submits' names:
array(
    'submitY' => 'Yes',
    'Message' => array(
        'test' => 'foo'
    )
)

array(
    '_method' => 'POST',
    'data' => array(
        'Message' => array(
            'test' => 'Bar'
        )
    ),
    'submitY' => 'Yes'
)
Then to determine which button is pressed you can use a simple isset($_POST['']) or over $this->request->data ?
