referrer

derksj

I am trying to write a script that makes that people only can visit a page from my website who come from the domain www.money-line.com
the code i wrote works for a page from this domain but i want to make it work for any page from this domain

if
($_SERVER['HTTP_REFERER']!="http://www.money-line.com/pg/docviewer.php?action=view&doc=12584") 
{ 
echo ("you may not visit this page"); 
} 
else 
{ 
echo ("<center><br><br><br><br><br><br><body onload=\"BodyOnLoad()\"><div ID=\"MyDiv\"></div>");
} 
?>

You could match the string against [url]http://[/url][www.]money-line.com

There are plenty of functions to match

preg_match is a good one

This is straight from the good ol' manual

<?php
// get host name from URL
preg_match("/^(http:\/\/)?([^\/]+)/i",
   "http://www.php.net/index.html", $matches);
$host = $matches[2];

// get last two segments of host name
preg_match("/[^\.\/]+\.[^\.\/]+$/", $host, $matches);
echo "domain name is: {$matches[0]}\n";
?>

This example will produce:

domain name is: php.net

so put in the referrer for http://www.php.net/inde.....

I cant get it working with my code
could you give me an example of how my code should look like

mtimdog

// get host name from URL 
preg_match("/^([url]http://[/url])?([^/]+)/i", 
   $_SERVER['HTTP_REFERER'], $matches); 
$host = $matches[2]; 

// get last two segments of host name 
preg_match("/[^./]+.[^./]+$/", $host, $matches); 


if 
($matches[0]!="money-line.com")  

{  

echo ("you may not visit this page");  

}  

else  

{  

echo ("<center><br><br><br><br><br><br><body onload=\"BodyOnLoad()\"><div ID=\"MyDiv\"></div>"); 
}  

?>

this little hack should work for ya'

if (!preg_match("/^http:\\/\\/www\\.money-line\\.com/", $_SERVER["REQUEST_URI"])) {
	include("page_blocked.html");
	exit();
}
