Passing Serialized Array via Hidden field

Hi, I am need to pass serialized assotiative array via form hidden field (not GET or POST). In order to do it, I did the following: urlencode(serialize($my_array)). However, after retrieving data from hidden field and unserialize I've got junk. Someone can explain me what I did wrong? Also, do I need to do addslashes/stripslashes with serialized (or encoded ?) data? Thanks in advance for any suggestion. ********************************************* * Best Regards --- Andrei Verovski * * Personal Home Page * http://snow.prohosting.com/guru4mac * Mac, Linux, DTP, Development, IT WEB Site *********************************************
