gravityflowpdf_file_name

• Introduction
• Parameters
• Examples
• Adds a prefix to the name of the file.
• Adds a prefix of the Step ID to the name of the file for certain steps.

Introduction

Use this filter to change the name of the PDF file generated via the PDF Generator Add-On.

1. To change the filename of PDF which users download from the server
   Use the gravityflowpdf_download_file_name filter. It has the exact same parameter structure and fully supports the {workflow_pdf_download_link} merge tag.
2. To create a copy of the PDF file on the server
   Use the gravityflowpdf_generated action hook.

Note: This filter changes the file name on the server and has been deprecated as it would cause possible issues with merge tags and PDF download links. If you were using it prior to deprecation (V1.5) we recommend two potential changes for your code:

Parameters

Examples

Adds a prefix to the name of the file.

add_filter( 'gravityflowpdf_file_name', 'sh_gravityflowpdf_file_name', 10, 3 );
function sh_gravityflowpdf_file_name( $file_name, $entry_id, $form_id ) {
	return 'my-pdf-' . $file_name;
}

Adds a prefix of the Step ID to the name of the file for certain steps.

add_filter( 'gravityflowpdf_file_name', 'sh_filename_with_step', 10, 3 );
function sh_filename_with_step( $file_name, $entry_id, $form_id ) {
	$api = new Gravity_Flow_API( $form_id );
	$entry = GFAPI::get_entry( $entry_id );
	$step = $api->get_current_step( $entry );
	if( $step->get_id() == '3' ) {
		$file_name = 'step-' . $step->get_id() . '-' . $file_name;
	}
	return $file_name;
}
