* to the list of whitelisted fields. This way they will become a part of the

|
||
|
*
|
||
|
* - Below in the switch statement - so the field is recognized as whitelisted.
|
||
|
*
|
||
|
* - Grunion_Contact_Form::process_submission - validation and logic.
|
||
|
*
|
||
|
* - Grunion_Contact_Form::process_submission - add the field as an additional
|
||
|
* field in the `post_content` when saving the feedback content.
|
||
|
*
|
||
|
* - Grunion_Contact_Form_Plugin::parse_fields_from_content - add mapping
|
||
|
* for the field, defined in the above method.
|
||
|
*
|
||
|
* - Grunion_Contact_Form_Plugin::map_parsed_field_contents_of_post_to_field_names -
|
||
|
* add mapping of the field for the CSV Export. Otherwise it will be missing
|
||
|
* from the exported data.
|
||
|
*
