gfpdf_maybe_attach_to_notification

Description

Use this filter to dynamically attach or exclude a PDF from the notification being processed.

Version

This filter was introduced in Gravity PDF 4.2.

Parameters

$attach | boolean

• Return true to attach the PDF to the current notification, or false otherwise.

$notification | array

• The current Gravity Forms notification being processed

$settings | array

• The current PDF settings being processed

$entry | array

• The raw Gravity Form Entry array.

$form | array

• The Gravity Forms array

Usage

The following will include all generated PDFs with all Gravity Forms notifications:

add_filter( 'gfpdf_maybe_attach_to_notification', function( $attach, $notification, $settings, $entry, $form ) {
	return true;
}, 10, 5 );

The above isn't really useful though. The below sample will attach any PDF with a name containing the word 'Submission' to any Gravity Form notification on form #5:

add_filter( 'gfpdf_maybe_attach_to_notification', function( $attach, $notification, $settings, $entry, $form ) {
	if ( $form['id'] === 5 && strpos( $settings['name'], 'Submission' ) !== false ) {
		return true;
	}

	return $attach;
}, 10, 5 );
