help blocking certain links

Ok i have a tinyurl service:

http://dd1.us/

but i want to block links from

Rapidshare.com
Rapidshare.de
megaupload.com

Here are all the files that would be necessary to be edited to do this:

Index.html

<img src="http://dd1.us/img/logo1.png"><br>
<h1>Free Short Url Redirection</h1>
<div class="spacer"><span></span></div>
      <form method="post" action="create.php">
<p>
          <label title="Enter Long Url Here | http:// To Make It Work">
            <input type="text" name="url" size="40" value="http://"  /></label><br />
          <label title="Submit URL To Make A Tinyurl">
<input type="submit" name="send" value="Make It Short!" class="submit" /></label></p>
<div class="spacer"><span></span></div>
      </form>

Code (markup):

.htaccess

RewriteEngine on
RewriteRule ^([0-9]+)/?$ /go.php?id=$1 [L] 

Code (markup):

Create.php

include("config.php");
if (strstr($_SERVER['HTTP_REFERER'], $root));
else { header ("Location: $rooturl"); }

$ip = $_SERVER['REMOTE_ADDR'];
$url = $_POST['url'];

if(preg_match('|^http(s)?://[a-z0-9-]+(\.[a-z0-9-]+)*(:[0-9]+)?(/.*)?$|i', $url))
{

$query = "INSERT INTO $table (ip,url) VALUES ('$ip','$url')" or die('MySQL error: '.mysql_error());
mysql_query($query);
$qs = mysql_insert_id();
$link = $destination . $qs;
require 'create_template.php';

} else {
echo 'Your URL is invalid';

}
?>

PHP:

Create_template.php

<?
echo "<center>Your New Short URL: <a href=$rooturl" . $qs . " target=_blank>$rooturl" . $qs . "</a></center><br />";
?>
<div id="content">

PHP:

go.php

ob_start();
include("config.php"); 
 
 
?>
		<?
		$id = $_GET['id'];
		if($id){

			$qs = mysql_query("SELECT url FROM $table WHERE id = $id") or die('MySQL error: '.mysql_error());
    mysql_query("UPDATE url SET count=(count + 1) WHERE id = $id");
			while($data = mysql_fetch_array($qs)){
if ($frame == 1) {
echo include("frame.php");
echo "<iframe name=\"pagetext\" height=\"100%\" frameborder=\"no\" width=\"100%\" src=\"$data[0]\"></iframe>"; }

else if ($frame == 0) {
echo header("Location: $data[0]"); }


}

		}else{
		?>
<?}

ob_flush();
?>

PHP:

These Are The Major Files IF there is way to block certain urls please let me know

 

any1 able to figure this out? ive searched and searched

 

trim out megaupload.com
in the string and rapidshare.de

I am sure that might work

 

not sure how to do that and dont know which file i would have to do it to

 

can any1 help? no1 noes how to do this? i have supplied all files in the first post

 

$parts = pars_url($url);
$host = strtolower($parts['host']);
$host = preg_replace('~^www\.~', null, $host);

$blocked = array('rapidshare.com', 'rapidshare.de', 'megaupload.com');

if (in_array($host, $blocked))
{
    // Blocked
}
else
{
    // Ok
}

PHP:

 

where do i put that code

also can a message pop up saying "This URL has been blocked"

 

Give it a go and show me what you've tried.

 

i tried in create & the index & create_template but i get errors for each one

 

^^^^^^



And if you get errors, you gotta come a bit more specific than that. How am I supposed to help if you tell me "I get errors"?

 

In Create_Template.php --- The error is:

Fatal error: Call to undefined function pars_url() in /home/duffy0/public_html/dd1.us/create_template.php on line 38

Line 38 is: $parts = pars_url($url);

------------------------------------------------

In Create.php -- The error is:

Fatal error: Call to undefined function pars_url() in /home/duffy0/public_html/dd1.us/create.php on line 27

Line 27: $parts = pars_url($url);

-----------------------------------------------

In Index.php -- The Error is:

Fatal error: Call to undefined function pars_url() in /home/duffy0/public_html/dd1.us/index.php on line 28

Line 28: $parts = pars_url($url);

 

My bad, it's a typo in my code. It should read parse_url().

 

ok i added it to create.php but it just ignores it acts like it is not even there no errors just runs hte regular script normal

 

Not sure how often I have to quote myself, lol:
