Detect hyperlinks in description fields

Detect hyperlinks in description fields was created by kristel
Hi,
When user post an ad, all "Description" fields (textearea) are recorded as plain text.
When the user writes a URL in the description field, I need the frontend to display hyperlinks.

So, I updated the following file to globally detect URLs in this type of field:
components/com_adsmanager/helpers/field.php

I would like to contribute to this module and provide my code in order to get it in the next release ;-) and make it useful for the community.

How should I proceed?

Thanks.

Ok sure,

So to display hyperlinks automatically in your ads, simply locate the file:
components/com_adsmanager/helpers/field.php

and add the following methods where ever you want in the class JHTMLAdsmanagerField:

Note: I simplified my method absolute_url() to keep it simple, but at least this gives you some guide lines.
function array_field($ar, $field) {
  $a = array();
  foreach($ar as $r) array_push($a, $r[$field]);
  return $a;
}
function absolute_url($uri, $external=false, $param=false) {
  if(!preg_match("#^https?://#i", $uri)) {
    $uri = "http://$uri";
  }
  return  $uri;
}
 
function htmlize_links($s) {
  preg_match_all("#(?!<=\S)(https?://)?(www\.)?[a-z0-9\.\-]+\.(com|org|edu|net|us|gov|uk|name|info|gl)(/\S*)?#i", $s, $matches, PREG_SET_ORDER);
  if($matches) {
    $links = $this->array_field($matches, 0);
    foreach($links as $i => $link) $links[$i] = preg_replace('/[\)\]]+$/', '', $link);
    $links = array_unique($links);
    foreach($links as $l) {
      $url      = $this->absolute_url($l);
      $link     = "<a href='$url' target='_blank'>$l</a>";
      $regexp   = "|(?!<=\S)".preg_quote($l, '|')."(?=[\s\)])|";
      $s        = preg_replace($regexp, $link, $s);
    }
  }
  return $s;
}

and in the method showFieldValue(), search for
case 'textarea':
                    $return .= str_replace(array("\r\n", "\n", "\r"), "<br />", $value);
                    break;

and replace it by
case 'textarea':
                    $return .= str_replace(array("\r\n", "\n", "\r"), "<br />", $this->htmlize_links($value));
                    break;
[

Hope this can help someone and this would be fantastic if you can package it with a switch in the backend UI :-)

Thanks

JT

This update to the functionality would be so helpful for the "non programmers" out there who need this feature. Please consider it for the next release.
