Question

我创建了一个按钮＆＃34;清除所有＆＃34;，它将数据发送到＆＃39; data.php＆＃39;点击按钮通过ajax

</head>
 <body> 
   <script type="text/javascript">
       function klick(id){
           $.ajax({
           type:"POST",
           url:"data.php",
           data:{id:id},                        
           success:function(resp){
           $('#w3').html(resp);                       
          }
        });                   
       } 
  </script>        
<a href="shop.php">shop</a>
<br><br>

   <button type='button'onclick= " klick()"/>clear all</button> 

</body>
</html>

这是我的data.php页面，所以我想做的是用空数组覆盖$ _SESSION [＆＃39; warenkorb＆＃39;]如果来自调用的变量出现在＆＃34; data.php＆＃34;页。

这样的事情：$_SESSION['warenkorb']=array();

 <html>
 <head>
   <title>DATA</title>
    <script src="https://www.novastorm.de/js/jquery-1.11.3.min.js"></script>
</head>
<body>    

  <?php         
     include 'produkte.php';           
     if(!isset($_SESSION['warenkorb'])){  
       $_SESSION['warenkorb']=array();
         }                                
     if(isset($_POST['id'])){             
      foreach($a as $key =>$value){  
      if($value['id']==$_POST['id']){                   
       $_SESSION['warenkorb'][]= $_POST['id'];              
       }              
     }
    }     
      print_r(count($_SESSION['warenkorb']));       
   ?>      
</body>
</html>

证明来自ajax调用的变量存在
