Gravity Forms Field Mapping Field

This plugin adds the ability to map form fields to user defined keys on the form settings screen.

The advantage is being able to programmatically refer to fields by key instead of ID:

add_action( 'gform_after_submission', function ( $entry, $form ) {
    $name_field_id    = '1';
    $email_field_id   = '2';
    $message_field_id = '3';
    
    $name    = rgar( $entry, $name_field_id );
    $email   = rgar( $entry, $email_field_id );
    $message = rgar( $entry, $message_field_id );
    
    // Once the fields have been mapped on the form settings screen, the above can be rewritten as:
    $name_field_key    = 'name';
    $email_field_key   = 'email';
    $message_field_key = 'message';
    
    $name    = \GravityFormsFieldMapping\get_mapped_field_value( $form['id'], $entry, $name_field_key );
    $email   = \GravityFormsFieldMapping\get_mapped_field_value( $form['id'], $entry, $email_field_key );
    $message = \GravityFormsFieldMapping\get_mapped_field_value( $form['id'], $entry, $message_field_key );
    
    // Do more stuff...
}, 10, 2 );

There are three helper functions to simplify retrieving form input data:

echo \GravityFormsFieldMapping\get_mapped_field_id( $form_id, 'email' ); // Output: 2

echo \GravityFormsFieldMapping\get_mapped_field_value( $form_id, $entry, 'email' ); // Output: name@domain.com

var_export( \GravityFormsFieldMapping\get_mapped_field_values( $form_id, $entry ) ); // Output: [ 'name' => 'First Last', 'email' => name@domain.com, 'message' => 'Test message' ]
