php 简单留言板教程三

好了,其它的都快完了我们就来看看index.php文件显示留方的页面吧.

<?php
@session_start();
include("global.php");

if(isset($_GET['act']) && $_GET['act'] == 'del')
{
  if(isset($_GET['mid']))
  {
   $mid = intval($_GET['mid']);
   if(mysql_query("DELETE FROM xx_guestbook WHERE mid={$mid}"))
   {
    echo("delete OK!");
    die("<script>window.location.href='{$_SERVER['PHP_SELF']}';</script>");
    //echo "<meta http-equiv=\"refresh\" content=\"1; url=index.php\">";
   }
   else echo("false");
  }
}
?>
