Change WooCommerce PDF Voucher string to custom name

woocommerce-pdf-voucher-custom-filename.php

<?php //only copy if needed

//filter documented at: https://docs.woocommerce.com/document/woocommerce-pdf-product-vouchers-developer-documentation/#wc_pdf_product_vouchers_voucher_filename
add_filter('wc_pdf_product_vouchers_voucher_filename', 'cs_my_own_filename');

function cs_my_own_filename ($filename) {
  // This is how the variable is defined: $filename = 'voucher-' . sanitize_file_name( $this->get_voucher_number() ) . '.' . $type;
  // Note: $type may be defined as string. Default $type = 'pdf';
  // Note: Do not use this filter to change the number. There are other filters for that.
  
  // Change string 'voucher' in filename to 'Gutschein'
	$myname = str_replace('voucher', 'Gutschein', $filename);
	$filename = $myname;
	return $filename;
  // Outputs the following Filename: Gutschein[voucher number].pdf
}

Love this, thank you!

Love this, thank you!

You are welcome!

Do I need to create an new file for this and where in my Child-Theme I have to put it in? Thank you.

Hi @MarkKbrook

You can put this in the functions.php of your child theme. There is no need to create a file.
