Links leaving site

zzz

I'd like to add a script that will convert URLs in text into links and if the links are pointing outside my website, display some sort of a notice that the user is about to leave the site, similarly to facebook or myspace functionality.

I'm sure it's been done many times and instead of re-inventing the wheel I'd like to get a head start. Could someone point me in a right direction?

I don't think this is a job for PHP.

I have just started looking at jQuery and believe it will do what you're describing, although it will only work if the user has javascript enabled.

JQuiry is good but I rather do it on a server side. When I load a link I can detect if domain is different then mine and link it to my page, something like outgoingLink.php while passing the link as a var. On that page (outgoingLink.php) I can put a warning and put the link that I passed as a var from a previous page. I think in theory is I'm OK. I need some function to replace URL with link.

OK, this will convert URL into clickable link.

$text = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]", "<a href=\"\\0\">\\0</a>", $text);

Now I just need to come up with a function that will sniff out that URL in a bliock of text, convert to link that will direct to my page something like this:

$long text = "sasd sa dasd ad ad.... http://somelink.com... ";

// after running through function: 
$long text = "sasd sa dasd ad ad.... <a href="mypage.php?http://somelink.com">http://somelink.com</a>... ";

OK, I got as far as I could on my own.

I need help with regex in .htaccess

I have this link:

<a href="http://www.mydomain.com/link;http://www.domain.com">http://www.domain.com</a>

Now I would like to add a rewrite rule to my .htaccess file to do something like this

RewriteRule ^/link;(http://.*)$ incl/externalLink.inc.php?URL=$1 [NC,L]

i.e. if URL has /link;http:// pull incl/externalLink.inc.php page and pass external URL as a var $URL.

I'm in the deep dark woods at the moment.
