php - Zend Session Identity losing object parameters -

i have strange problem can't seem track down. have custom class ("person") extending zend_db_table_row_abstract represents user. among other things, class has custom variables set in init() method, instance:

class person extends zend_db_table_row_abstract {         protected $_cdata = array(); // non-db-table data gets put here through __set()          public function init()         {            $this->fullname = $this->firstname." ".$this->lastname; // saved $this->_cdata['fullname']         }  

upon login, store object of class zend auth identity:

$r = $auth->authenticate($authadapter); if($r->isvalid()) {   $user = $db->getuserbyemail($email); // retrieves object of class "person"   $auth->getstorage()->write($user); } 

now, if call auth identity in same action request login, work alright:

echo $user->fullname; // print "john smith" or whatever 

however, when call action, , call auth identity, lose whatever have stored in "_cdata" array:

$auth = zend_auth::getinstance(); if($auth->hasidentity() {    $user = $auth->getidentity();    echo $user->fullname; // prints nothing...$_cdata['fullname'] not exist. } 

any ideas?

the reason why that's happening because zend_auth identity data gets serialized (and deserialized) between requests.

which leads closer onto __sleep method of zend_db_table_row_abstract class, 1 gets called once $user object serialized.

public function __sleep() {     return array('_tableclass', '_primary', '_data', '_cleandata', '_readonly' ,'_modifiedfields'); } 

what need override method in person class, includes $_cdata array well. property serialized , available in next http request.
