Question

这是food.php的页面，它将链接到order.php以将订单添加到购物车中。

<input type="hidden" name="id" value="<?php echo $row["foodID"];?>" />
            <dt>
            <img src="<?php echo  $row["food_img"];?>" />
            <input name="img"  type="hidden" class="img" value="<?php echo  $row["food_img"];?>" /> </dt>
            <dd>

         <form action="order.php" method="get" name="send" onSubmit="return Check()"  enctype="multipart/form-data">
                <h3><?php echo  $row["food_name"];?>
                <input name="name"  type="hidden" class="name" value="<?php echo  $row["food_name"];?>" /></h3>
                <div class="detailtips">
                    <?php echo  $row["food_description"];?>
                </div>
                <p><span>Restaurant:</span><strong><?php echo  $row["restaurant_name"];?>
                <input name="restaurant"  type="hidden" class="restaurant" value="<?php echo  $row["restaurant_name"];?>" />
                </strong></p>
                <p><span>Type :</span><strong><?php echo  $row["food_type"];?></strong></p>

                <input name="num"  type="hidden" class="num" value="<?php echo  $row["order_num"];?>" />

                <p><span>Price :</span>RM &nbsp;<strong><?php echo  $row["food_price"];?>
                <input name="price"  type="hidden" class="price" value="<?php echo  $row["food_price"];?>" /></strong></p>

                <div class="order" style=" padding-top:20px; padding-left:20px;">
                <input name="" type="submit"  value="" class="ordersubmit" style=" margin-left:30px; margin-top:20px;">
                </div>
                </form>

这是order.php

<?php session_start();  
ini_set('error_reporting', 'E_ALL ^ E_NOTICE');
header("Content-type: text/html; charset=utf-8"); 
include("conn.php");

$action = $_GET['action'];
$user = $_SESSION['username'];
foreach ($_GET AS $key=>$value)
{
$key ;
}
$nameid=substr($key,4);
$namenum=$_GET[$key];
if($namenum){
    $arr = mysql_query("select * from  ordering  where id='$nameid'");
    $rowres = mysql_fetch_array($arr);
    $total=$rowres['food_price']*$namenum;
    $sqlup="update ordering SET  order_num='$namenum', total='$total' where id='$nameid'" ;
    $rus = mysql_query($sqlup);
  }
  if(empty($user)){
  echo "<script>alert('No login, please log in!');window.location='Log In.php';</script>";
  exit;
  }
  $orderID = $_GET['id'];
  $food_img = $_GET['img'];
  $food_name = $_GET['name'];
  $restaurant_name = $_GET['restaurant'];
  $food_price = $_GET['price'];
  $order_num = $_GET['num'];

  $total=$food_price*$order_num;
  if($action == 'add'){

   $arr = mysql_query("select * from  ordering  where id='$orderID'");
    $rowres = mysql_fetch_array($arr);

    $row=mysql_num_rows($arr);   
  if($row>0){$ordernum=$rowres['order_num']; 
      $t_price=$rowres['food_price'];
         $ordernum=$ordernum+$order_num;
                $t_pricea=$t_price*$ordernum;
            $sql="update ordering set order_num='$ordernum', total='$t_pricea' where id='$orderID' ";
             $resulta = mysql_query($sql);
                if($resulta==true)
  {
   echo "<script>alert('success');window.location.href='order.php'</script>";
  }
  }else{

    $sqlin="INSERT INTO ordering (`id`,`orderID`,`food_img`,`food_name`,`restaurant_name`,`food_price`,`total`,`order_num`,`username`,`time`)  VALUES('','$orderID','$food_img','$food_name','$restaurant_name','$food_price','$total','$order_num','$user',now()) ";
    $rus = mysql_query($sqlin);
       if($rus==true)
  {
   echo "<script>alert('success');window.location.href='order.php'</script>";
  }

      } 

  }

  ?>
  <?PHP 
  if($action=="delcar"){
  $delid=$_POST['delcar'];
  $pieces = explode(",", $delid); 
  if($pieces==""){
            echo "<script language=\"javascript\">alert('please choose!');window.location.href='order.php'</script>";die;

      }
   $arrayLen = sizeof( $pieces );
   for( $i = 0; $i< $arrayLen ;$i++ )
   {
   $sql="delete from  ordering where id='$pieces[$i]'";    

   $result=mysql_query($sql);  }
   if($result==true)
   {
   echo "<script language=\"javascript\">alert('del  success!');window.location.href='order.php'</script>";die;
   }else{
    echo "<script language=\"javascript\">alert('del  failed, please re-enter!');window.location.href='order.php'</script>";die;
   }    

   }
   ?>

这是链接到orderlist.php的表单

   <div class="shopbox">
    <form method="get" action="orderlist.php" id="shopcarall" >
    <input type="hidden" name="action" value="change" />

 <div class="shopmain">

<ul><li style="padding:30px 10px 0 0"><input name="chackcar[]" type="checkbox"  class="userid"  value="<?php echo $row['id']?>" /></li>
      <li class="boxa"> <img src="<?php echo $row['food_img'];?>" width="130" height="98"> </li>
      <li class="boxb">
    <h3>Food name</h3>
    <h4><?php echo $row['food_name'];?> </h4>
  </li>
   <li class="boxc">
    <h3>Restaurant</h3>
    <h4> <?php echo $row['restaurant_name']; ?> </h4>
  </li>
      <li class="boxc">
    <h3>Food  price</h3>
    <h4> <?php echo $row['food_price']; ?> </h4>
  </li>
      <li class="boxc">
    <h3>Order  num</h3>

       <h4>

         <a class="del" href="javascript:void(0)"> - </a><input type="text" name="<?php echo $row['id']; ?>" class="inputcss" value="<?php echo $row['order_num']; ?>" style=" margin:0; float:left">
        <a class="add" href="javascript:void(0)"> + </a>
        </h4>

  </li>
      <li class="boxc">
    <h3>Total</h3>
    <h4>RM <?php echo $row['total'];?></h4>
  </li>
    </ul>


            </div>
    </form>

为什么food.php中的价值我无法获得order.php？我的编码有什么不对吗？由于输入的名称与$ _GET [＆＃39;＆＃39;]匹配，我仍然不知道为什么数据没有显示？
