Summary

The All Fields Template is causing a fatal error: Warning: Undefined variable $input_ids in /.../gw-all-fields-template/gw-all-fields-template.php on line 201

The issue is down to the $input_ids only getting initialized in the preceding else block (and not the if). This leads to potential scenarios of tapping in on that value/variable even though it does not exist.
