Description
It's a PR send in github. https://github.com/WordPress/WordPress/pull/273
Fix empty charset in line 436.
Before:
Content-Type: multipart/alternative; charset=
After:
Content-Type: multipart/alternative; charset=UTF-8
fix $headers[] = "Content-Type: multipart/alternative; boundary=\"$boundary\""; not send when not other headers.
Test Code:
<?php $boundary = md5( uniqid() . microtime() ); $to = 'wordpress@wordpress.org'; $subject = 'TEST'; $headers[] = "From: Wordpress <wordpress@wordpress.org>"; $headers[] = "Content-Type: multipart/alternative; boundary=\"$boundary\""; $body = "--$boundary\r\n" . "Content-Type: text/plain; charset=UTF-8\r\n"; $body .= 'test'; $body .= "--$boundary\r\n" . "Content-Type: text/html; charset=UTF-8\r\n"; $body .= '<div>test</div>'; wp_mail( $to, $subject, $body, $headers );

It's not being ignored by
wp_mailbut by PHPMailer. When setting custom headers, theboundaryis removed as it fallback as a regularplainemail.Already reported upstream, and this has become essentially a duplicate of #15448
When we sort out the multipart problem, this will be sorted also. I hope we can achieve this before 6.9 release. Stay tuned to the other report.
