ajax - Why php doesn't see the $_SESSION[] array anywhere? -

-

i'm writing php code processing lot of data, interactively. in starting php page call function session_start() before sending other data browser. then, put data $_session[] array, this:

$_session['something'] = $variable;

after, there form, sent via , xmlhttprequest.

getrequest.open("get", "data_processing.php?var="+onevalue+"&another_var="+twovalue, true) getrequest.send(null)

another php script recieves user data get, , there i'd use data stored in $_session well. $_session seems empty. i've never used sessions, correct way make available variables consequent php scripts?

are sure called session_start first?

see: http://php.net/manual/en/function.session-start.php

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
