Custom Fields – Where To Start?

open the ttgps-functions.php and find the
$site = isset($_POST["site"]) ? $_POST["site"] : "";

line. after this line add what you want. for example ,this plugin posts phone value ,but not create any custom field as it’s name or value. i add ttgps-functions.php this line and all done ;

$phone = isset($_POST["phone"]) ? $_POST["phone"] : "";

beware about ,if you want to create custom fields , POST values must return from tt-guest-post-submit.php .If $_POST[“phone”] not exist in tt-guest-post-submit.php ,you must create a form element as is.
