fun.php 這是壹個功能函數
left.php 網站後臺根據用戶登錄的ID來加載相對應的功能菜單
op.php 調用adminconfig.php 默認權限文件
opsava.php 保存用戶權限成壹個php文件
好了我們先來看看 fun.php文件吧。
. 代碼如下:
<?
function findsub($keys ,$userid='abc' ) //此函數重要就是為了調用用戶的權限信息
{
include('user/'.$userid.'.php');
foreach($bb as $key=>$submenu)
{
foreach($submenu as $subkey=>$menuitem)
{
if( $subkey == $keys )
{
return 1;
}
}
}
}
//下面為生成用戶的php權限文件
//寫入
function cache_write($name, $var, $values) {
$cachefile = 'op/www.hzhuti.com/'.$name.'.php';
$cachetext = "<?phprn".'$'.$var.'='.arrayeval($values)."rn?>";
if(!swritefile($cachefile, $cachetext))
{
exit("File: $cachefile write error.");
}
}
//數組轉換成字串
function arrayeval($array, $level = 0) {
$space = '';
for($i = 0; $i <= $level; $i++) {
$space .= "t";
}
$evaluate = "Arrayn$space(n";
$comma = $space;
foreach($array as $key => $val) {
$key = is_string($key) ? '''.addcslashes($key, ''\').''' : $key;
$val = !is_array($val) && (!preg_match("/^-?d+$/", $val) || strlen($val) > 12) ? '''.addcslashes($val, ''\').''' : $val;
if(is_array($val)) {
$evaluate .= "$comma$key => ".arrayeval($val, $level + 1);
} else {
$evaluate .= "$comma$key => $val";
}
$comma = ",n$space";
}
$evaluate .= "n$space)";
return $evaluate;
}
//寫入文件
function swritefile($filename, $writetext, $openmod='w') {
if(@$fp = fopen($filename, $openmod)) {
flock($fp, 2);
fwrite($fp, $writetext);
fclose($fp);
return true;
} else {
exit("File: $filename write error.");
return false;
}
}
>adminconfig.php 後臺權限配置文件,以壹個數組形式保存
. 代碼如下:
<?
$menus = array(
'news' => array(
'caption'=>'資訊管理',
'icon'=>'admin/icon_15.gif',
'sub' => array(
'newsaddtype' => array('caption' => '分類增加', 'url' => 'news/addtype.php'),
'newstypemange' => array('caption' => '分類管理', 'url' => 'news/typemange.php'),
'newsnewsend' => array('caption' => '發布資訊', 'url' => 'news/newsend.php'),
'newsnewmange' => array('caption' => '資訊管理', 'url' => 'news/newmange.php'),
'newscomments' => array('caption' => '評論管理', 'url' => 'news/comments.php'),
),
),
'ask' => array(
'caption'=>'問卷調查',
'icon'=>'admin/icon_15.gif',
'sub' => array(
'voteadmin_subject_add' => array('caption' => '添加投票主題', 'url' => 'vote/admin_subject_add.php'),
'voteadmin_subject' => array('caption' => '管理投票主題', 'url' => 'vote/admin_subject.php'),
'voteadmin_title_add' => array('caption' => '添加投票問題', 'url' => 'vote/admin_title_add.php'),
'voteadmin_title' => array('caption' => '管理投票問題', 'url' => 'vote/admin_title.php'),
'voteadmin_question_add' => array('caption' => '添加投票答案', 'url' => 'vote/admin_question_add.php'),
'voteadmin_question' => array('caption' => '管理投票答案', 'url' => 'vote/admin_question.php'),
'voteadmin_system' => array('caption' => '投票初始配置', 'url' => 'vote/admin_system.php')
),
),
'ads' => array(
'caption'=>'廣告管理',
'icon'=>'admin/icon_15.gif',
'sub' => array(
'ada' => array('caption' => '增加廣告', 'url' => 'ada.php'),
'adm' => array('caption' => '廣告管理', 'url' => 'adm.php'),
'flashadd' => array('caption' => '焦點圖廣告增加', 'url' => 'flashadd.php'),
'flashad' => array('caption' => '焦點圖廣告管理', 'url' => 'flashad.php')
),
),
'mange' => array(
'caption'=>'系統管理員',
'icon'=>'admin/icon_15.gif',
'sub' => array(
'adminuser' => array('caption' => '管理員添加', 'url' => 'adminuser.php'),
'modpass' => array('caption' => '密碼修改', 'url' => 'modpass.php')
),
),
);
>left.php文件很簡單就是根據用戶登錄後ID讀出權限
. 代碼如下:
<?
$userid = $_SESSION['adminid'];
include("op/admincofig.php");
include("op/ www.hzhuti.com /".$userid.".php");
foreach($bb as $key=>$submenu)
{
echo "<tr><td bgcolor="#D879A7" style="line-height:22px;text-align:center;color:#ffffff;"> nr <font color="#EA6A8D" face="Webdings"></font><b>".$menus[$key]['caption']."</b><br /></td></tr> nr <tr ><td bgcolor="F5E8F1">";
foreach($submenu as $subkey=>$menuitem)
{
$tmparr = explode("|",$menuitem);
echo "<font color="#EA6A8D" face="Webdings">4</font><a href='".$tmparr[1]."' target="mainframe">".$tmparr[0]."</a><br> nr";
}
echo "</td></tr> nr ";
}
op.php這個文件就是要調用我們的adminconfig.php文件，然後利用fun.php文件中函數把提供過來的數據保存成數組如圖
點擊保存我們調用了opsava.php 文件，代碼如下
. 代碼如下:
<?
include("op/fun.php");
if( $_POST )
{
$sarray = $_POST ;
cache_write($userid,'bb',$sarray);//寫入緩存
echo "<script>alert('編輯保存成功！');location='op.php?userid=".$userid."';</script>";
}
>保存成功後文件內容如
. 代碼如下:
<?php
$bb=Array
(
'member' => Array
(
'user_search' => '會員升級管理|user_search.php'
),
'membercy' => Array
(
'cyuser_search' => '會員升級管理|cyuser_search.php',
'cyuser_search5' => '交友會員|cyuser_search.php?grade=5'
),
'userid' => 7,
'button' => '保存編輯'
)
>這樣的話我們的left只要加載 7.php文件就只會顯示這裏在的文件，這樣壹個基本的後臺權限就完成了。
