I am allowing people to post comments using a textarea field and sometimes they post urls. What I need to do is to convert this url from db before displaying it as a real clickable link, but without allowing html tags. I would prefer to do it using php or jquery if possible. I thought about using something like [link][/link] but I need to do it without any extra effort from the website member. Any ideas please??
example :
[link]http://www.google.com[/link] Here is a little PHP script that I have written. It seems to work for me. It uses the preg_match_all and preg_replace methods to match all the links inserted by the end user with <a> tags.
<?php $text="Click [link]http://www.google.com[/link] or click [link]http://www.yahoo.com[/link]"; preg_match_all('/\\[link](.*?)\\[\/link]/s', $text, $links); $link_count=count($links); for($i=0;$i<$link_count;$i++){ $link_url=preg_replace("/\[link]/", "", $links[0][$i]); $link_url=preg_replace("/\[\/link]/","",$link_url); $text=str_replace($links[0][$i],"<a href=\"" . $link_url . "\">" . $link_url . "</a>",$text); } echo $text; ?> use regex to find urls within the block of text, then append and prepend the necessary tags

You can use preg_replace method:
//URL's $pattern = "/\[link\=(.*)\](.*)\[\/link\]/i"; $replace = "<a href=\"$1\">$2</a>"; echo preg_replace($pattern, $replace, $subject);
