I made a blog and It is function nicely right now, well actually I used a guestbook script for it. What I want to do is when a user posts a link, if would automatically make it a clickable link to that address. How can this be done? Is it possible in html or php?

Thanks!

Try this for html :

Quote:

private string ConvertUrlsToLinks(string msg) {
string regex = @"((www\.|(http|https|ftp|news|file)+\:\/\/)[_.a-z0-9-]+\.[a-z0-9\/_:@=.+?,##%&~-]*[^.|\'|\# |!|$|?|,| |>|<|;|$])";
Regex r = new Regex(regex, RegexOptions.IgnoreCase);
return r.Replace(msg, "<a href=\"$1\" title=\"Click to open in a new window or tab\" target=\"_blank\">$1</a>").Replace("href=\"www", "href=\"http://www");
}

Try this for php :

Quote:

function parse_links($html){

$html = preg_replace('/\\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|]/i', "<a href=\"#\" onclick=\"open_url('\\0')\";return false;>\\0</a>", $html);
return $html;

}

There is some problem with that . Try this for PHP:

Quote:

<?
$message = eregi_replace("((([ftp://])|(http(s?)://))((:alnum:|[-\%\.\?\=\#\_\:\&\/\~\+\@\,\;])*))","<a href = '\\0' target='_blank'>\\0</a>",$message);

$message = eregi_replace("(([^/])www\.|(^www\.))((:alnum:|[-\%\.\?\=\#\_\:\&\/\~\+\@\,\;])*)","\\2<a href = 'http://www.\\4' target='_blank'>www.\\4</a>",$message);
?>
