This modifier will automatically hyperlink URLs in text, and also hyperlink email addresses, javascript encoded. It is smart enough to handle http:// addresses, as well as www. addresses without the http:// prefix. It also truncates the url text in the link.

Hi monte,

[php:1:b78e401212]return '<a href="' . str_replace('&','&',$link) . '" target="_blank" rel="nofollow">'[/php:1:b78e401212]

why do you replace '&' with '&' ?

Bye,
Markus

Hi,
I read your post and would like to know where this goes. Do I create a new directory or what. Please advise.

Thanks
