Subject: Bugfix: set_error() must accept an array of errors
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=603ff7b2d9786bad50b054b43d60c76dded5bd42;p=koopa

Bugfix: set_error() must accept an array of errors

This is considered a bug because the current design of get_error() returns an array if errors.
Prior to this, calling set_error($some_class->get_error()) would result in no error being reported because the array value gets ignored.

With this change, the entire array contents are appended, only if the given array value is a valid error class instance.
