echo 提交表單數據 php/html/sql

[英]echo submited form data php/html/sql

 原文  2021-06-22 16:11:14  8   1    php/ html/ sql/ submit

問題描述

我有一個表單 (testform.php)，我嘗試在另一個頁面 (view.php) 上回顯提交的數據，但它不起作用，我該怎么辦？ 另一個頁面是（preparedstatement.php）它的過程。

我嘗試使用 $post, $echo 回顯它，但它不起作用，我有點迷茫（我是 php 新手）

您的view.php沒有獲得 $_POST 值。

是否要考慮使用$_SESSION或$_GET來獲取view.php 中cde和ivoucher的值？

您只需$ _ POST更改為$ _GET在view.php並更改重定向在preparedstatement.php ：

<?php 
    header('Location: view.php?cde='.$_POST["code"].'&ivoucher='.$_POST["id_voucher"]);
?>
