修改Emlog的文章加密及PHP任意页面设置访问密码-小易传媒工作室资源网

只要是PHP程序，不管是网站任意页面或程序都可使用如下代码加密，包括但不限于文章页，独立页面等！

Emlog 的文章访问密码页面

修改include/model/log_model.php 文件末尾的 authPassword 函数；将原来函数里的

if ($pwd !== addslashes($logPwd)) {

            echo <<<EOT
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>emlog message</title>
<style type="text/css">
<!--
body{background-color:#F7F7F7;font-family: Arial;font-size: 12px;line-height:150%;}
.main{background-color:#FFFFFF;margin-top:20px;font-size: 12px;color: #666666;width:580px;margin:10px 200px;padding:10px;list-style:none;border:#DFDFDF 1px solid;}
-->
</style>
</head>
<body>
<div class="main">
<form action="" method="post">
请输入该文章的访问密码<br>
<input type="password" name="logpwd" /><input type="submit" value="进入.." />
<br /><br /><a href="$url">&laquo;返回首页</a>
</form>
</div>
</body>
</html>
EOT;
            if ($cookiePwd) {
                setcookie('em_logpwd_' . $logid, ' ', time() - 31536000);
            }

替换为如下代码即可：

		if ($pwd !== addslashes($logPwd)) {
			?>
