I've been redesigning my xoopsgallery template set - my first attempt at serious theme modification. I've run into a problem with the comments controls (ex "nested | oldest first | post" etc.). This particular table is hard-coded in include/comment_view.php and called (via smarty function?) by {$commentsnav} . I would like to hack this table, but whenever I modify comment_view.php, even just changing the table class, the script fails to work (ie. {$commentsnav} returns nothing) and I get the following php warning:

Notice [PHP]: Use of undefined constant php - assumed 'php' in file include/comment_view.php line 1

What am I doing wrong?
