我们正在尝试发布到同一操作的两种表单。 我们正在尝试从第一种形式检索输入字段txt1的值并将其传递给控制器列表，其中该值被发送以在第二种形式的for循环中使用以动态创建表单。 但是这个错误正在显示： “未定义的变量：计数器[APP \ View \ Lists \ add.ctp，第107行] CakePHP：快速开发php框架 CakePHP 2.6.1“ 我附加了控制器和视图的代码

答案 0 :(得分：0)
当数据进入保存时，你已经设置了'$ rd'变量。当页面加载时，它首次出现，然后它不会进入你的if条件
if(!empty($this->data['List']['txt1']))
{
echo 'kkl';
if($this->RequestHandler->isAjax())
{
echo 'dddd';
$this->set('rd',$this->data['List']['txt1']);
$this->render('add','ajax');
}
}
你应该在函数的开头设置'rd'变量，就像这样
$this->set('rd','');
现在rd变量将在页面加载或保存数据中同时设置两种情况
