Php 如何在数据库上提交签出产品详细信息？

我在电子商务网站上工作，一切都很好。现在我在结账页面上。客户首先填写账单明细，然后下订单

我正在数据库中获取账单详细信息，但没有获取订单详细信息

checkout.php

    <form action="process.php" method="Post">
    <!--bill details field--> 
    //fields 
   <!--end bill details field-->

    <!--shipping detials filed--> 
    //Shipping details   
    <!--end shipping detials filed-->

    <!--order detials are(Session is working perfectly)-->
     if(!empty($_SESSION['product_cart'])):
     foreach($_SESSION['product_cart'] as $key=>$product):
      ?>
     <li>
      <div class="order-list">
      <img src="admin/images/products/<?php echo $product['p_images'];?>"> 
      <?php echo $product['p_brandname'];?>
      <div class="circle-qty"><?php echo $product['quantity'];?></div>
          <span>$<?php echo $product['p_total'];?></span> 

       <input type="hidden" name="o_product_name[]" value="<?php echo $product['p_brandname'];?>">
       <input type="hidden" name="o_product_qty[]" value="<?php echo $product['quantity'];?>">
       <input type="hidden" name="o_product_single_cost[]" value="<?php echo $product['p_currentprice'];?>">
       <input type="hidden" name="o_product_totalcost[]" value="<?php echo $product['p_total'];?>">
                </div>
                 </li>
       <?php $total_amount[]= $product['p_total'];//getting all the product price and assigning to array for total amount?>
            <?php endforeach;?>
       <li class="checkout-total"><div><h2>Total</h2><span>$<?php echo array_sum($total_amount);?></span></div></li>
<?php endif;?>
    </form>

echo $o_product_name=$conn->real_escape_string(trim($_POST['o_product_name']));
echo $o_product_qty=$conn->real_escape_string(trim($_POST['o_product_qty']));
echo $o_product_single_cost=$conn->real_escape_string(trim($_POST['o_product_single_cost']));
echo $o_product_totalcost=$conn->real_escape_string(trim($_for each_product_totalcost']));

Process.php

    <form action="process.php" method="Post">
    <!--bill details field--> 
    //fields 
   <!--end bill details field-->

    <!--shipping detials filed--> 
    //Shipping details   
    <!--end shipping detials filed-->

    <!--order detials are(Session is working perfectly)-->
     if(!empty($_SESSION['product_cart'])):
     foreach($_SESSION['product_cart'] as $key=>$product):
      ?>
     <li>
      <div class="order-list">
      <img src="admin/images/products/<?php echo $product['p_images'];?>"> 
      <?php echo $product['p_brandname'];?>
      <div class="circle-qty"><?php echo $product['quantity'];?></div>
          <span>$<?php echo $product['p_total'];?></span> 

       <input type="hidden" name="o_product_name[]" value="<?php echo $product['p_brandname'];?>">
       <input type="hidden" name="o_product_qty[]" value="<?php echo $product['quantity'];?>">
       <input type="hidden" name="o_product_single_cost[]" value="<?php echo $product['p_currentprice'];?>">
       <input type="hidden" name="o_product_totalcost[]" value="<?php echo $product['p_total'];?>">
                </div>
                 </li>
       <?php $total_amount[]= $product['p_total'];//getting all the product price and assigning to array for total amount?>
            <?php endforeach;?>
       <li class="checkout-total"><div><h2>Total</h2><span>$<?php echo array_sum($total_amount);?></span></div></li>
<?php endif;?>
    </form>

echo $o_product_name=$conn->real_escape_string(trim($_POST['o_product_name']));
echo $o_product_qty=$conn->real_escape_string(trim($_POST['o_product_qty']));
echo $o_product_single_cost=$conn->real_escape_string(trim($_POST['o_product_single_cost']));
echo $o_product_totalcost=$conn->real_escape_string(trim($_for each_product_totalcost']));

我试图显示该值，但不起作用。即使我尝试使用内爆函数，但也不起作用

 foreach($o_product_name as $key => $value)
{
   echo $key." has the value". $value;
 }

//second tried
$string=implode(",",$o_product_name);
echo $string;

你能帮我一下吗？

$\u POST['o\u product\u name']

是一个数组。不能在修剪函数中传递数组。在process.php文件中，需要循环遍历$\u POST数组

foreach($_POST['o_product_name'] as $key=>$value)
{
echo $o_product_name=$conn->real_escape_string(trim($_POST['o_product_name'][$key]));
}

另一个也一样。请检查语法错误，因为我没有测试代码，但它应该可以正常工作

谢谢。

在process.php中，不能在trim（）方法中使用数组

---

因为给定的参数是数组，而不是预期的字符串。谢谢，它对我有用。
