Question

This is my function:

    function makeClickableLinks($s) {
  return preg_replace('@(https?://([-\w\.]+[-\w])+(:\d+)?(/([\w/_\.#-]*(\?\S+)?[^\.\s])?)?)@', '<a href="$1" target="_blank">$1</a>', $s);
}


$description = $_POST['description'];

echo makeClickableLinks($description);

$_POST[‘description’] is a form textarea that will be inserted later into a MySQL table.

I want to allow users to create links within this input field. When I use this function, user inputted data that looks like this:

Whats up guys. Here's my website! Please check it out!!
<a href="google.com">hi</a>

Is now a clickable link, but links to:

http://(myurl).com/google.com

It thinks the link is a subdirectory. Any ideas? THankS!

Answer 1

As I understand you want to organize something like replacing the references in the user’s records, so that they referred to your site. Tray this regexp:

<?php
$str = "Whats up guys. Here's my website! Please check it out!!
<a href='google.com'>hi</a> and something:)";

echo preg_replace("/(<a[^<]* href=['\"])(http:\/\/|https:\/\/)?([^\"]*?)(['\"][^<]*>)/is", "$1mysite.com/$3$4", $str);
