下面的代码是我编写的程序。问题是,即使我按下提交、回复或删除,按钮都不起作用。

你能帮我看看我在下面写的代码有什么问题吗?太感谢了。

<?php

/*共通処理*/

//データベースへの接続
try{
$GLOBALS['db'] = new PDO("mysql:host=localhost; dbname=bbs", "root", "test");    
} catch (PDOException $e) {
    echo 'connection failed: '.$e->getMessage();
}

//action取得
$action = (isset($_GET['action']) ? $_GET['action'] : $_POST['action']);

//action振り分け
switch($action)
{
        //書き込み処理
    case "regist":
        proc_regist();
        break;

        //削除処理
    case "delete":
        proc_delete();
        break;

        //返信処理
    case "res":
        proc_res();
        break;

        //表示処理
    default:
        proc_default();
        break;

}

// 終了処理



/* ここで処理は終了 あとは個別の関数へ */


// 基本の掲示板表示処理
function proc_default()
{

    $db = $GLOBALS['db'];


    $page_max = 15;
    $offset = ( isset($_GET['offset']) ? $_GET['offset'] : 0 );

    $limit = $page_max +1;

    $stmd = $db->query("select * from message order by no desc limit $limit offset $offset");
    $rows = $stmd->fetchAll();

如果你试试这个呢?

print "<input type='submit' name='action' value='write'>\n";
print "<hr>\n";
print "記事番号:&lt;input type='text' name='delno'>\n";
print "削除キー: <input type='password' name='delkey'>\n";
print "<input type='submit' name='action' value='delete'>\n";
print "<input type = 'hidden' name = 'action' value = 'delete'>\n"; (remove this line)
