This filter contains the full array of all our different Gravity PDF sections and their associative field information. It combines the output from filters like gfpdf_settings_general and gfpdf_settings_tools into a single array. This filter is very useful if you want to make changes to multiple section fields at the same time or need to add multiple fields to different sections.


$gfpdf_settings | array : An associative array that includes a breakdown of each section available in Gravity PDF. These sections contain another associative array which lists of the fields for a section. For more details about how fields are structured in the configuration review our custom PDF configuration guide.


This snippet shows how you can output fields to multiple sections of the Gravity PDF UI:

add_filter( 'gfpdf_registered_fields', function( $gfpdf_settings ) {

* Ensure you prefix the array key and ID to prevent any conflicts

if ( isset( $gfpdf_settings['general'] ) ) {
$gfpdf_settings['general']['prefix_border_colour'] = array(
'id' => 'prefix_border_colour',
'name' => __('Field Border Colour', 'prefix-text-domain' ),
'type' => 'color',
'desc' => __('Control the colour of the field border.', 'prefix-text-domain' ),
'std' => '#CCCCCC'

if ( isset( $gfpdf_settings['form_settings'] ) ) {
$gfpdf_settings['form_settings']['prefix_my_custom_radio'] = array(
'id' => 'prefix_my_custom_radio',
'name' => 'My Custom Radio',
'desc' => 'This is my field description',
'type' => 'radio',
'options' => array(
'Yes' => __( 'Yes', 'prefix-text-domain' ),
'No' => __( 'No', 'prefix-text-domain' ),
'std' => __( 'No', 'prefix-text-domain' ),

return $gfpdf_settings;
} );
