Hi,
so if you'd like to transform it always to callto: protocol you have to use custom display callback.
To do the job easy you should create directories and a file with a class and a method like this:
File: modules/Custom/CallTo/Skype.php
class Custom_CallTo_Skype {
public static function display_callto($data, $nolink, $desc){
$login = $data[$desc['id']];
if ($nolink) return $login;
$callto = 'callto:' . $login;
return "<a href=\"$callto\">$login</a>";
}
}
Filename and class name are correlated.
Then go to RB Admin panel, edit your field, check Advanced ... and fill Value display function with Custom_CallTo_Skype::display_callto
Such changes will persist over EPESI update.
Regards,
Adam
