在CakePHP 1.3中,您可以创建一个包含多个提交按钮的表单:
echo $this->Form->submit('Submit 1', array('name'=>'submit');
echo $this->Form->submit('Submit 2', array('name'=>'submit');
并检测控制器中按下了哪个提交按钮:
if (isset($this->params['form']['submit']) && $this->params['form']['submit'] == "Submit 1") {
// first button clicked
}
在CakePHP中,$ this-> params ['form']未设置,点击的按钮值不会出现在$ this-> request,$ this-> request-> ; data,$ this-> params,$ this-> data或$ _POST 。
如何确定在CakePHP 2.0中点击了哪个按钮?
提前致谢。
编辑:
根据要求,这是表格的代码:
<?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()?>
表格的输出:
<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>

通常,对两个提交按钮使用相同的名称是不好的做法。 $ _POST和$ this-&gt;请求 - &gt;数据中应该有一个“提交”键
我在CakePHP 2.1.1中对此进行了测试,如下所示:
观看代码:
<?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 $this->Form->end()?>
控制器中的$ this-&gt; request-&gt; data:
array(
'submit' => 'Yes',
'Message' => array(
'test' => 'TestFieldTest'
)
)
在$ _POST中:
array(
'_method' => 'POST',
'data' => array(
'Message' => array(
'test' => 'TestFieldTest'
)
),
'submit' => 'Yes'
)
您还可以为这两个提交不同的名称:
echo $this->Form->submit('Yes', array('div'=>false, 'name'=>'submitY'));
echo $this->Form->submit('No', array('div'=>false, 'name'=>'submitN'));
这样您可以在$ _POST或$ this-&gt; request-&gt;数据中区分它们,因为密钥将是提交的名称:
array(
'submitY' => 'Yes',
'Message' => array(
'test' => 'foo'
)
)
array(
'_method' => 'POST',
'data' => array(
'Message' => array(
'test' => 'Bar'
)
),
'submitY' => 'Yes'
)
然后要确定按下哪个按钮,您可以使用简单的isset($ _ POST [''])或$ this-&gt; request-&gt;数据?

不要对两个提交按钮使用相同的名称。考虑这个例子:
<?php echo $this->Form->create(false); ?>
<?php echo $this->Form->text('input'); ?>
<?php echo $this->Form->submit('Yes', array('name' => 'submit1')); ?>
<?php echo $this->Form->submit('No', array('name' => 'submit2')); ?>
<?php echo $this->Form->end(); ?>
单击“是”按钮时,debug($ this-&gt; request-&gt; data)将产生以下内容:
array(
'submit1' => 'Yes',
'input' => 'test'
)
这是点击“否”按钮的时候:
array(
'submit2' => 'No',
'input' => 'test'
)
检查点击了哪个按钮:
if (isset($this->request->data['submit1'])) {
// yes button was clicked
} else if (isset($this->request->data['submit2'])) {
// no button was clicked
}

不再有$this->params['form']
所有表单助手发布的字段最终都在$this->data
中(无论如何都更有意义)
所以
if (!empty($this->data['submit']) && $this->data['submit'] == "Submit 1") {}
请注意!empty()在这里也更好。
PS:您可以使用我的增强型升级shell在代码中替换它:https://github.com/dereuromark/upgrade
它的命令

if (!empty($this->request->data['submit']) && $this->request->data['submit'] == "Yes") {
// do your stuff
