PHP二级目录分页失败

SK214545015 2015-10-29 01:51:28

现在有一个PHP写的目录直读程序，根目录可以做到翻页，但是二级目录翻页的时候还是显示根目录的页面，求大神帮忙改一下。

这个是index.php

<?php
define('WEBROOT', dirname(__FILE__));
require_once WEBROOT . '/config.php';
require_once WEBROOT . '/function.php';
//图片目录,相对主目录
$dir = ($_GET['imgdir'] == '') ? $root : $_GET['imgdir'].'/';
$os = PHP_OS;
if($os != 'WINNT') {
$dirmsg = explode("/", $dir);
$dirurl = array();
foreach($dirmsg AS $val) {
if($val) {
$dirurl[] = rawurlencode($val);
}
}
$rootdir = implode('/', $dirurl).'/';
} else {
$rootdir = $dir;
}
$list = getDirList($dir);
$imgArr = changeList($list);
?>

<?php showImgList($imgArr, $_GET['page'], $pageSize);?>
</DIV>
<DIV id="quicklinks">
<a href="javascript:history.back(-1)">返回上一页</a>
</div>
</BODY></html>

这个是config.php

$siteName = '我的相册';
//note:站点地址
$siteUrl = 'http://www.ismole.net';
//note:图片目录,相对于程序根目录
$root = 'images/';
$pageSize = 24;

这个是调用的函数 function.php

}
return $html;
}
