Best choice is predefined list of allowed pages:
| Code: |
$page = empty($_GET['page']) ? 'home' : $_GET['page'];
$allowed = array('home', 'page2', 'page3');
if( in_array($page, $allowed) )
{
require($page . '.html');
}
else
{
die('Hacking attempt?');
}
|
And if you have lot's of pages and don't want to list them all, then you must sanitize incoming page name carefully:
| Code: |
$page = empty($_GET['page']) ? 'home' : $_GET['page'];
if(preg_match('/[^a-zA-Z0-9-_]/', $page))
{
die('Hacking attempt?');
}
$page = "$page.html";
if(!is_file($page))
{
die('Page not found!');
}
require($page);
|
Let me know, if you have questions  |
