00835: AuthForm doesn't handle arrays in _POST properly

Description: See http://bugs.gnewsense.org/Bugs/00043 for original report. Issue is that WikiForms sends dates as <input name="dataopened[]"> which turns the POST into 'dateopened'=>array('2006','11','22')

I am closing this entry as duplicate of 01110 -- the future fix should handle associative arrays with multiple dimensions, so the code will be slightly different. --Petko February 25, 2010, at 09:31 AM

The fix is a change in pmwiki.php:
