Description #description

This field can be used to create new core PDF template fields and make them available to the PDF configuration.

Parameters #parameters

$fields | array
The associative array which holds the field ID in the array key and the method/function which will get passed to PHP’s call_user_func function.
$template_settings | array
The current template settings being run. Read more about template configurations here.
$class | object
The current template’s configuration class being processed.

Usage #usage

This snippet shows how to leverage this filter to create a new core field and define that core field’s settings:

add_action( 'gfpdf_core_template_fields_list', function( $fields, $template_settings, $class ) {
    $fields['prefix_custom_core_field'] = 'prefix_custom_core_field_function'; /* the value references our callback. Anything PHP's `call_user_func` function accepts can be passed here */

    return $fields;
}, 10, 3 );

 * This is our callback function which includes our new field details
 * See for details about the array structure
 * If a PDF template configuration passes `prefix_custom_core_field` as true in it's core array this field will now show on the PDF template tab
function prefix_custom_core_field_function() {
    return array(
        'id' => 'prefix_custom_core_field',
        'name'    => __( 'Custom Field', 'prefix-text-domain' ),
        'type'    => 'radio',
        'options' => array(
            'Yes' => __( 'Yes', 'gravity-forms-pdf-extended' ),
            'No'  => __( 'No', 'gravity-forms-pdf-extended' ),
        'std'     => __( 'No', 'gravity-forms-pdf-extended' ),

    return $fields;

While this adds a new core field you still need to process the value when set. Use the gfpdf_core_template action to do this.

Source Code #source-code

This filter is located in the Model_Form_Settings::setup_core_custom_appearance_settings() method of /src/model/Model_Form_Settings.php.
