Fixed XF\Mail\Mail incorrect string length handling

[Xon]

Affected version

2.1.0 Patch 2

XF\Mail\Mail::setContent will fail when handling the string 0 due to simple $htmlBody/!$htmlBody checks instead of using strlen.

These arguments should also be converted from stringable objects to string as well before doing length checks

 

[XF Bug Bot]

Thank you for reporting this issue, it has now been resolved. We are aiming to include any changes that have been made in a future XF release (2.2.0 Beta 3).

Change log:

Appropriately handle text/body strings passed into Mail::setContent when length checking.

There may be a delay before changes are rolled out to the XenForo Community.
