gfpdf_form_settings_appearance

Description

This filter can be used to add new fields to the Appearance settings section for individual PDFs. It's basically a Fields API and all validation, sanitising and saving is handled automatically for you.

Parameters

$fields | array

Usage

The following sample shows you how to add two new fields to the Appearance section of the contextual PDF settings pages:

add_filter( 'gfpdf_form_settings_appearance', function( $fields ) {

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

/* Add a colour picker to the General PDF Settings page */
$fields['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'
);

/* Add a Radio button to the General PDF Settings page */
$fields['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 $fields;
} );

The following snippet shows you how to change the label of an existing field:

add_filter( 'gfpdf_form_settings_appearance', function( $fields ) {

if ( isset( $fields['pdf_size'] ) ) {
$fields['pdf_size']['name'] = __( 'Page Size', 'prefix-text-domain' );
}

return $fields;
} );
