By including the following function, you can customise the code for sending a twitter explicit RSS Feed Title so the words longer than xxx are and have a hash placed in front of them for twitters RSS Aggregation
function xoopsTweetString($title, $doit=false, $wordlen=4) {
if ($doit==true) {
$title_array = explode(' ', $title);
$title = '';
foreach($title_array as $item) {
if (strlen($item)>$wordlen)
$title .= ' #'.$item;
else
$title .= ' '.$item;
}
}
return trim($title);
}
The RSS Code with this included would look like:
