zend会话在课堂上不起作用

Question

I am using zend session, it workssetting up on the index page and if i use jquery's and check any session data. how ever within my class the session is empty?

index.php

$usersession = new Zend_Session_Namespace();
$usersession->surveyType = array("2D","3D");
$usersession->surveyTypeSelect = 'all';

file i use for jquery

$session = new Zend_Session_Namespace();
$log = $session->log;
$cache = $session->cache;
$surveyType = $session->surveyType;
$surveyTypeSelect = $session->surveyTypeSelect;

my class

$seismicLibrary = new Spectrum_Seismic_Library();

Any function within this class returns empty values for my saved session data.

public function getAllSurveysByRegionId($regionId, $published = false) {
        //'Default'
        $session = new Zend_Session_Namespace();
        $log = $session->log;
        /*foreach ($session as $index => $value) {
            $log->debug(print_r("aNamespace->$index = '$value';\n",true));
        }*/
        $surveyType = $session->surveyType;     
        $surveyTypeSelect = $session->surveyTypeSelect;

The above function - session data is empty.

Answer 1

You are setting a new session namespace in that function rather than retrieving the one you already had. You could try creating your session, then setting it to registry using Zend_Registry::set('session', $session) then when you need it anywhere else you use $session = Zend_Registry::get('session'); that way you ensure that you are using the same session namespace.
