gform_us_states

Description

This filter can be used to modify the choices listed in the US states drop down.

Usage

add_filter( 'gform_us_states', 'your_function_name' );

Parameters

$states array

The array to be filtered. It contains the list of states in a standard array (see sample below).

$states = array(
    'Alabama',
    'Alaska',
    'Arizona',
    'Arkansas',
    'California'
    // ... more states
);

Examples

1. Use State Code

This example demonstrates how to use the two letter state code as the choice value.

add_filter( 'gform_us_states', 'us_states' );
function us_states( $states ) {
    $new_states = array();
    foreach ( $states as $state ) {
        $new_states[ GF_Fields::get( 'address' )->get_us_state_code( $state ) ] = $state;
    }

    return $new_states;
}

Note: This example does not change the display value, just the stored value. This will store the 2-letter state code in the entry and is required for some add-ons.

2. Remove States

add_filter( 'gform_us_states', 'filter_us_states' );
function filter_us_states( $states ) {
    $omit_states = array(
        'Alaska',
        'Hawaii'
    );

    foreach ( $states as $key => $state ) {
        if ( in_array( $state, $omit_states ) ) {
            unset( $states[ $key ] );
        }
    }

    return $states;
}

3. Add Outlying Territories to US State List

add_filter( 'gform_us_states', 'us_states' );
     function us_states( $states ) {

     $territories = array(
         2 => 'American Samoa',
         12 => 'Guam',
         37 => 'Northern Mariana Islands',
         42 => 'Puerto Rico',
         48 => 'United States Minor Outlying Islands',
         49 => 'U.S. Virgin Islands'
     );

     foreach ( $territories as $key => $t ) {
         array_splice( $states, $key, 0, $t );
     }
     return $states;
 }
