Add an attachment

Hi, you can create a new function to search in uploads an attachment with a name “month-based”: if the file exists, it will be attached in newsletter.
The code is something like:

function custom_easymail_newsletter_attachment_monthly ( $attachs, $newsletter ) {

	$month_file = WP_CONTENT_DIR . '/uploads/neswletter_'.date( 'Y_m' ).'.pdf';

	if ( @file_exists( $month_file ) ) {
		return $month_file;
	}
	return array();
}
add_filter ( 'alo_easymail_newsletter_attachments',  'custom_easymail_newsletter_attachment_monthly', 10, 2 );

So you have to prepare the files inside upload folder, one for each month: neswletter_2017_12.pdf, neswletter_2018_01.pdf …
I hope it can be a good starting point for you.

Hi jwpalfa, maybe you can use the standard attachments.
So you can add files to a newsletter using the standard “add media” button. Then, all attached pdf files will be attached inside newsletter.
Please try the following code (I didn’t tested it but I think it could work):

function custom_easymail_newsletter_get_attachments ( $attachs, $newsletter ) {

	$get_attachments = get_attached_media( 'application/pdf', $newsletter->ID );

	$attachs = array();
	if ( $get_attachments ) {
		foreach( $get_attachments as $attachment ) {
			$attachs[] = get_attached_file( $attachment->ID );
		}
	}
	return $attachs;
}
add_filter ( 'alo_easymail_newsletter_attachments',  'custom_easymail_newsletter_get_attachments', 10, 2 );

Please let us know if it works.

You have to upload the file and insert it in newsletter in order to attach (=link) it to the newsletter. It’s the reason why if you get an existing file but uploaded in another post or what ever, it will not recognized as an attachment.

Once you uploaded a file using media button in newsletter and the link is added inside newsletter content, this file is attached to newsletter (you should see the relation also in Media list table, in relationship column): so at this point I think you can remove the link from content because the file is anyway attached. Let us know if I remember well and if it works.

Good idea, I’ll add this sample in developers page and also inside mu-plugins folder in EasyMail.
