原文外掛簡介
Full State Name for Gravity Forms fixes an annoying inconsistency in Gravity Forms: depending on the form, the add-on, and the code path, the Address field’s “State / Province” sub-input (input X.4) sometimes resolves to a 2-letter abbreviation (“NJ”) and sometimes to the full state name (“New Jersey”) when used in merge tags.
This causes real problems with:
Notification emails that read “Your shipment is going to NJ.”
{all_fields} output mixing full city names with state codes.
URL query strings that pre-populate another Gravity Form — the second form’s state dropdown doesn’t match “NJ” against its option value of “New Jersey”, so the field stays blank.
The Solution
This plugin hooks into gform_merge_tag_filter and, only when the merge tag targets an Address field’s State sub-input (X.4) and the value is exactly a 2-letter code, expands it back to the full state name that Gravity Forms uses in its Address field dropdown.
Key Features
Targeted — Only affects Address field State sub-inputs (X.4), nothing else
Safe — Only acts when the value is exactly two letters; existing full names and other text pass through untouched
Zero Configuration — Activate the plugin and the fix is live
Filterable — Override or extend the code-to-name map with the fsn_gf_state_map filter for non-US addresses or translated labels
Filterable expansion — Hook fsn_gf_expanded_state_name to customize the replacement on a per-field basis
Where It Applies
{all_fields} merge tag
{Address (State / Province):X.4} merge tag
Notifications, confirmations, and any place merge tags are processed
URL query strings built with merge tags (so the receiving form’s state dropdown picks the correct option)
Covered Codes
All US states (50), DC, US territories (PR, GU, VI, AS, MP), and military mailing regions (AA, AE, AP) — a total of 59 entries that match the default Gravity Forms Address state options exactly.
