Add ability to save the pdf to wp-content/uploads

[joldnl]

For a client project I needed the cart pdf to be saved as an offer. So the client needs to have the pdf with the cart contents.

So I added some small functionality that saves the pdf to the wp-content/uploads/wc-cart-pdf folder.

This can be enabled with a new filter: 'wc_cart_pdf_save', which defaults to false, but can ben set to true to have it saved on disk.

Please let me know what you think of this.

I have added a custom action to execute before outputting the pdf. This is handy if you want to send an email with the pdf, or create a custom post or something.

En example of how to use the custom 'wc_cart_pdf_after_action' action:

// Send the cart-pdf to the site administrator email address
add_action( 'wc_cart_pdf_after_action', 'wc_cart_pdf_after_action', 10, 2 );
function wc_cart_pdf_after_action($uploads_folder, $filename) {

	$to = get_option('admin_email');
	$subject = 'Nieuwe Offerte';
	$message = 'Howdy Ho,<br><br>You have a new pdf: <a href="' . wp_upload_dir()['baseurl'] . '/wc-cart-pdf/' . $filename . '">' . $filename . '</a>';
	$headers = ['Content-Type: text/html; charset=UTF-8'];
	$attachments = $uploads_folder . $filename;

	wp_mail( $to, $subject, $message, $headers, $attachments );

}
