I have already made this script in the past, but never finished ironing out a couple of quirks.

When I get the chance, I'll dig through my code libraries and find my work and post it unfinished (no time and interest in completing it).

I searched, and can't find my code. I don't think I saved it.

But if it's any help to you most of my code changes for that feature were in bbcode.php

Its a pity cause i think it could be very very usefull: so google does not sees external links ( and our PR does not goes down ) and in the same time all logged in users can see external urls that in some cases ( in my forum for exemple ) its very important that exists.
I hope that sone someone could develop this feature soon!
Thanks again

Craven need your help! Crying or Very sad

I tried this in bbcode but does not work!
In this way it does NEVER show the link even if a user is logged in-

Code:



if ( $userdata['session_logged_in'] )

{

function make_clickable($text)

{



	// pad it with a space so we can match things at the start of the 1st line.

	$ret = " " . $text;



	// matches an "xxxx://yyyy" URL at the start of a line, or after a space.

	// xxxx can only be alpha characters.

	// yyyy is anything up to the first space, newline, or comma.

	$ret = preg_replace("#([\n ])([a-z]+?)://([a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+]+)#i", "\\1<a href=\"\\2://\\3\" target=\"_blank\">\\2://\\3</a>", $ret);



	// matches a "www.xxxx.yyyy[/zzzz]" kinda lazy URL thing

	// Must contain at least 2 dots. xxxx contains either alphanum, or "-"

	// yyyy contains either alphanum, "-", or "."

	// zzzz is optional.. will contain everything up to the first space, newline, or comma.

	// This is slightly restrictive - it's not going to match stuff like "forums.foo.com"

	// This is to keep it from getting annoying and matching stuff that's not meant to be a link.

	$ret = preg_replace("#([\n ])www\.([a-z0-9\-]+)\.([a-z0-9\-.\~]+)((?:/[a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+]*)?)#i", "\\1<a href=\"http://www.\\2.\\3\\4\" target=\"_blank\">www.\\2.\\3\\4</a>", $ret);



	// matches an email@domain type address at the start of a line, or after a space.

	// Note: Only the followed chars are valid; alphanums, "-", "_" and or ".".

	$ret = preg_replace("#([\n ])([a-z0-9\-_.]+?)@([\w\-]+\.([\w\-\.]+\.)?[\w]+)#i", "\\1<a href=\"mailto:\\2@\\3\">\\2@\\3</a>", $ret);



	// Remove our padding..

	$ret = substr($ret, 1);



	return($ret);

}

}



else

{

function make_clickable($text)

{

	// pad it with a space so we can match things at the start of the 1st line.

	$ret = " " . $text;



	// matches an "xxxx://yyyy" URL at the start of a line, or after a space.

	// xxxx can only be alpha characters.

	// yyyy is anything up to the first space, newline, or comma.

	$ret = preg_replace("#([\n ])([a-z]+?)://([a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+]+)#i", "\\1<font color=\"#FFFF00\"\>LINK VISIBILE SOLO SE LOGGATI</font>", $ret);



	// matches a "www.xxxx.yyyy[/zzzz]" kinda lazy URL thing

	// Must contain at least 2 dots. xxxx contains either alphanum, or "-"

	$ret = preg_replace("#([\n ])www\.([a-z0-9\-]+)\.([a-z0-9\-.\~]+)((?:/[a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+]*)?)#i", "\\1<font color=\"#FFFF00\"\>LINK VISIBILE SOLO SE LOGGATI</font>", $ret);

	$ret = substr($ret, 1);



	return($ret);

Finally SOLVED!
I made myself this mod so im very PROUD ( it's my FIRST ONE ).

Open includes bbcode.php

find:

Code:



function make_clickable($text)

{



	// pad it with a space so we can match things at the start of the 1st line.

	$ret = " " . $text;



	// matches an "xxxx://yyyy" URL at the start of a line, or after a space.

	// xxxx can only be alpha characters.

	// yyyy is anything up to the first space, newline, or comma.

	$ret = preg_replace("#([\n ])([a-z]+?)://([a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+]+)#i", "\\1<a href=\"\\2://\\3\" target=\"_blank\">\\2://\\3</a>", $ret);



	// matches a "www.xxxx.yyyy[/zzzz]" kinda lazy URL thing

	// Must contain at least 2 dots. xxxx contains either alphanum, or "-"

	// yyyy contains either alphanum, "-", or "."

	// zzzz is optional.. will contain everything up to the first space, newline, or comma.

	// This is slightly restrictive - it's not going to match stuff like "forums.foo.com"

	// This is to keep it from getting annoying and matching stuff that's not meant to be a link.

	$ret = preg_replace("#([\n ])www\.([a-z0-9\-]+)\.([a-z0-9\-.\~]+)((?:/[a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+]*)?)#i", "\\1<a href=\"http://www.\\2.\\3\\4\" target=\"_blank\">www.\\2.\\3\\4</a>", $ret);



	// matches an email@domain type address at the start of a line, or after a space.

	// Note: Only the followed chars are valid; alphanums, "-", "_" and or ".".

	$ret = preg_replace("#([\n ])([a-z0-9\-_.]+?)@([\w\-]+\.([\w\-\.]+\.)?[\w]+)#i", "\\1<a href=\"mailto:\\2@\\3\">\\2@\\3</a>", $ret);



	// Remove our padding..

	$ret = substr($ret, 1);



	return($ret);



}

After add:

Code:





function make_clickable1($text)

{

	// pad it with a space so we can match things at the start of the 1st line.

	$ret = " " . $text;



	// matches an "xxxx://yyyy" URL at the start of a line, or after a space.

	// xxxx can only be alpha characters.

	// yyyy is anything up to the first space, newline, or comma.

	$tret = preg_replace("#([\n ])([a-z]+?)://([a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+]+)#i", "\\1<font color=\"#FFFF00\"\><i>LINK VISIBILE SOLO AGLI UTENTI REGISTRATI</i></font>", $ret);



	// matches a "www.xxxx.yyyy[/zzzz]" kinda lazy URL thing

	// Must contain at least 2 dots. xxxx contains either alphanum, or "-"

	// yyyy contains either alphanum, "-", or "."

	// zzzz is optional.. will contain everything up to the first space, newline, or comma.

	// This is slightly restrictive - it's not going to match stuff like "forums.foo.com"

	// This is to keep it from getting annoying and matching stuff that's not meant to be a link.

	$ret = preg_replace("#([\n ])www\.([a-z0-9\-]+)\.([a-z0-9\-.\~]+)((?:/[a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+]*)?)#i", "\\1<font color=\"#FFFF00\"\><i>LINK VISIBILE SOLO AGLI UTENTI REGISTRATI</i></font>", $ret);



	// matches an email@domain type address at the start of a line, or after a space.

	// Note: Only the followed chars are valid; alphanums, "-", "_" and or ".".

	$ret = preg_replace("#([\n ])([a-z0-9\-_.]+?)@([\w\-]+\.([\w\-\.]+\.)?[\w]+)#i", "\\1<font color=\"#FFFF00\"\><i>LINK VISIBILE SOLO AGLI UTENTI REGISTRATI</i></font>", $ret);



	// Remove our padding..

	$ret = substr($ret, 1);



	return($ret);

}

Open viewtopic.php

Code:



{$message = make_clickable($message);}

Code:







if ( $userdata['session_logged_in'] )

{$message = make_clickable($message);}

{$message = make_clickable1($message);}

Save and upload

If u want to remove also the BBcode urls:

Open templates/subSilver/bbcode.tpl

find:

Code:



<!-- BEGIN url --><a href="{URL}" target="_blank" class="postlink">{DESCRIPTION}</a><!-- END url -->

replace with:

Code:



<!-- BEGIN url -->{DESCRIPTION} {URL}<!-- END url -->
