[phpniki]

با سلام
اگه یه فلدر داری که می خوای اون فلدر و تمام فلدر های زیر مجموعشو محدود کنی و کاربرا حتما با یوزر و پس دانلود کنن می تونی از سورس زیر استفاده کنی
تو این مثال فلدر files رو محدود می کنی
این کد رو تو فایل .htaccess کپی کنید

Options +FollowSymLinks -Indexes
RewriteEngine On
RewriteBase /

RewriteRule   ^files/(.*)$  download.php?filename=$1

این کد رو تو فایل download.php قرار بدید:

<?
//sample filename = Hamed/myfile.zip

$file_path = $_REQUEST['filename'];
list($username,$file_name) = explode("/",$file_path);


$member_info = checkLogin(); // -1 means user is not login
if($member_info != -1)
    $LoginSuccessful    = true;
else
{
    $LoginSuccessful    = false;
    $Logout             = false;    
}
$CurrentUrl         = 'http://' . $_SERVER['HTTP_HOST'] . '/download.php';
 

// if user send the username and password

    $usr = $_SERVER['PHP_AUTH_USER'];

    $member_info = login($usr,$pwd,1);
