I bought gravity forms and I'm trying to figure out how to make the title of the post be populated by what the users select as the category and the title plus another word. I found this link http://www.gravityhelp.com/documentation/page/Gform_pre_submission
So it would be like on
$_POST["input_6"] = no clue what this is suppose to be;
I know i need to pull from field id 1 which is the category field
and i want to use a generic word between that and the tag field which is field id 3. I'm just sorta lost on how to word it since I'm new to php. Can anyone point me in the right direction?
