MySQL UPDATE使用梨DB創建新記錄

Question

我正在使用PEAR DB進行基本的添加/編輯/刪除表單。我的添加和刪除功能正常工作，但我的編輯功能正在創建重複記錄，而不是編輯活動記錄。

我已經搜索論壇，MySQL手冊和php.net，但沒有太多的文檔。我工作的網站已經很老了，據我所知，很少有人正在使用Pear DB，因爲像CodeIgniter這樣的框架現在可以走了。如果可以的話，我會切換這個網站，相信我。這就是說，任何幫助排除這一點將不勝感激！

這裏是我的代碼：

<?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">

你在你的表單動作爲重點，用「模式」，但你正在尋找$_GET['action']，而不是$_GET['mode']。這是導致交換機運行的默認設置，因爲沒有$_GET['action']
