Question

我正在尝试循环一个变量，该变量的数据来自另一个数组循环

HERE是循环

for ($i=0; $i < $cid; $i++){
$message .= '<tr>
            <td>'.$pcode.'</td>
            <td>'.$pname.'</td>
            <td>'.$pprice.'</td>
            <td>'.$pqty.'</td>
            </tr>';
}

<td></td>中的变量是从此循环中生成的

foreach($_POST['item_cid'] as $key => $value) {

$cid = mysqli_real_escape_string($connection,$value);
$pcode = mysqli_real_escape_string($connection,$_POST['item_code'][$key]);
$pname = mysqli_real_escape_string($connection,$_POST['item_name'][$key]);
$pprice = mysqli_real_escape_string($connection,$_POST['item_price'][$key]);
$pqty = mysqli_real_escape_string($connection,$_POST['item_qty'][$key]);

}

我不知道如何使这个循环工作，我没有提交错误，

我正确循环吗？

更新后的代码：

<?php
session_start();
require('admin/connect.php');
require('includes/phpmailer/PHPMailerAutoload.php');

ini_set('display_errors',1);
error_reporting(E_ALL);

if (isset($_POST['submit'])) {

$resultArr = array();
$i = 0;
foreach($_POST['item_cid'] as $key => $value) {
//Data for Orders Table
    $cid = intval(mysqli_real_escape_string($connection,$value));
    $pcode = mysqli_real_escape_string($connection,$_POST['item_code'][$key]);

Answer 1

试试这个：

$message = "";
$resultArr = array();
$i = 0;
foreach($_POST['item_cid'] as $key => $value) 
{
   $cid = mysqli_real_escape_string($connection,$value);
   $pcode = mysqli_real_escape_string($connection,$_POST['item_code'][$key]);
   $pname = mysqli_real_escape_string($connection,$_POST['item_name'][$key]);
   $pprice = mysqli_real_escape_string($connection,$_POST['item_price'][$key]);
   $pqty = mysqli_real_escape_string($connection,$_POST['item_qty'][$key]);
   $resultArr[$i] = array('cid' => $cid, 'pcode' => $pcode, 'pname' => $pname, 'pprice' => $pprice, 'pqty' => $pqty);
   $i++;
}
$i = 0;
for ($i=0; $i < (isset($resultArr[$i]['cid']) && $resultArr[$i]['cid'] ?$resultArr[$i]['cid'] : 0); $i++)
{
$message .= '<tr>
         <td>'.$resultArr[$i]['pcode'].'</td>
         <td>'.$resultArr[$i]['pname'].'</td>
         <td>'.$resultArr[$i]['pprice'].'</td>
         <td>'.$resultArr[$i]['pqty'].'</td>
         </tr>';
}

Answer 2

这样的事情怎么样？

$message = "";
foreach($_POST['item_cid'] as $key => $value) 
{
   $cid = mysqli_real_escape_string($connection,$value);
   $pcode = mysqli_real_escape_string($connection,$_POST['item_code'][$key]);
   $pname = mysqli_real_escape_string($connection,$_POST['item_name'][$key]);
   $pprice = mysqli_real_escape_string($connection,$_POST['item_price'][$key]);
   $pqty = mysqli_real_escape_string($connection,$_POST['item_qty'][$key]);

   for ($i=0; $i < $cid; $i++)
   {
   $message .= '<tr>
            <td>'.$pcode.'</td>
            <td>'.$pname.'</td>
            <td>'.$pprice.'</td>
            <td>'.$pqty.'</td>
            </tr>';
   }
}

在另一个循环之后循环变量
