变量未传递给cakephp中的视图

Question

我们正在尝试两种形式发布到同一操作。 我们正在尝试从第一种形式中检索输入字段txt1的值，并将其传递到控制器列表，该值将在该控制器列表中发送以在第二种形式的for循环中使用以动态创建表单。 但是显示了此错误：“未定义的变量：计数器[APP \\ View \\ Lists \\ add.ctp，第107行] CakePHP：快速开发的PHP框架CakePHP 2.6.1”，我正在为控制器和视图附加代码

视图：

 <script>
     $(document).ready(function() {  

         $('#txtt1').on('change',function(){

             var paper=$(this).val();
                //alert('hello');
             if(paper<=0)
               alert('No of members should be greater than zero');
             if(paper!='')
               //$('#apap').hide();
         });
     });
</script>
<h2>Member Details</h2>

   <div id="post1">
</div>
<?php
echo $this->form->create('List',array('action'=>'add'));

//echo $this->form->input('txt2',array('id'=>'txt2'));
echo $this->Js->submit('Enter No. of Panel Members: ',array('update'=>'#success','id'=>'apap','class'=>'butstyle'));

?>
 </div>

 {
    echo $this->form->create('List',array('action'=>'add','type'=>'file','id'=>'frm'));?>

   ?>

    <?php } ?>


  </div>

Answer 1

您已在数据保存时设置了'$ rd'变量。这意味着第一次在页面加载时不会在if条件下进入

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');

            }
        }

您应该在函数的开头设置“ rd”变量，如下所示

$this->set('rd','');

现在，即使在页面加载或保存数据时，rd变量都将同时设置
