gfpdf_core_template_fields_list
Jump To Section
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.
