Description

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

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

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

* 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.
