我正在使用cake php 3.0来开发一个应用程序。当用户尝试编辑其详细信息时，成功的Flash消息会多次出现，因为表单已多次提交。我正在使用cake php form builder。这是我的代码
<?= $this->Form->create('Project'); ?>
<?= $this->Html->link(' キャンセル 編集', array('action' => 'view', $project['id']), array('class' => 'btn btn-default pull-right', 'style' => 'margin: 5px 14px 0 0', 'rule' => 'button')); ?>
<?= $this->Form->button(__(' 保存 '), array('class' => 'btn btn-default pull-right', 'style' => 'margin: 5px 14px 0 0 ', 'id' => 'edit', 'onsubmit'=> 'disable()')); ?>
<h3 style="font-weight:bold; padding-left:10px; margin: 10px 0 20px;"> 案件基本情報 </h3>

如何防止多次提交。使用cake php的功能或使用任何其他方法。我已经尝试加载csrf组件，但这对我没用。

我做了什么来阻止多个表单提交，是在提交和操作完成它的工作后，我重定向到另一个URL或相同。
<?php
public function add(){
//Grab data and validate it
if($this->save($data)){
$this->Flash->set(...);
return $this->redirect(array('action', 'index')); // redirect to prevent resubmission
}
//Do other processing ...
}

根据我的经验，重复的表单提交通常总是双击......等等。只需让您的提交<button>调用一个禁用该按钮的JavaScript函数，然后提交表单就可以防止这种情况发生。
您可以考虑在隐藏字段中向表单添加唯一ID，以检测仍然可以通过的任何重复提交，但第一个选项应该可以解决问题。
