MySQL UPDATE正在使用Pear DB創建新記錄

Question

我正在使用PEAR DB處理基本的添加/編輯/刪除表單。 我的添加和刪除功能正常運行，但是我的編輯功能正在創建重復記錄，而不是編輯活動記錄。

我已經搜索了論壇，MySQL手冊和php.net，但是那里沒有太多的文檔。 我正在工作的站點很舊，而且我了解使用Pear DB的人很少，因為像CodeIgniter這樣的框架現在已經成為了發展之路。 相信我，我會盡可能切換此站點。 就是說，任何幫助解決此問題將不勝感激！

這是我的代碼：

<?php 

require 'controller.php';
global $dbc;
$member_id = $_GET['memberid'];
$aid = $_GET['aid'];

/* Handle Accounting Actions -- Add, Edit, Delete */

$action = isset( $_GET['action'] ) ? $_GET['action'] : "";

switch ($action) {

  case 'add':
    add_aid();
    break;

  case 'edit':
    edit_aid();
    break;

  case 'delete':
    delete_aid();
    break;

  default:
    add_aid();
    break;
}


function add_aid()
{
    global $dbc;
    $member_id = $_GET['memberid'];
    $aid = $_GET['aid'];

?>


    <form name="add accounting record" action="?module=members&amp;mode=edit" method="post">

您在表單操作中使用“模式”作為鍵，但您正在尋找$_GET['action']而不是$_GET['mode'] 。 由於沒有$_GET['action']這將導致您的交換機運行默認值
