PHP Session with an Incomplete Object

PHP Session with an Incomplete Object

It's missing the serialize/unserialize of your template class.

Take a look here for an working example I gave on another question of yours.

For instance, you probably want this:

<?php
  $_SESSION['template'] = serialize($template);
?>

and

<?php
  $template = unserialize($_SESSION['template']);
?>

Edit:

reading your comment about moving it to the top gives one hint.

The automatic serialization/unserialization occurs when you call session_start().

That means the order in which you include your files and call the session_start() is very important.

For example:

This would be wrong:

<?php
session_start();
include 'inc/template.class.php';
?>

While this would be correct:

<?php
include 'inc/template.class.php';
session_start();
?>

Now, I see in your example that it is in the CORRECT order, but I also notice you do many other includes before including template.class.php

Would it be possible that one of those includes (perhaps prep.php or header.class.php) does call start_session() too?

If yes, that was your issue (session_start() being called before your template.class.php).

__PHP_Incomplete_Class Object even though class is included before session started

To store an object in a session two things must happen:

1) The class must be defined before the session is started.
2) The class must implement serializable.

PHP - Session can't store classes?

You must ensure that the class definition is loaded before you session_start(), otherwise a default class (with no methods) is created instead.

Auto-loading classes wont work. Nor will loading class definitions AFTER session_start.

Incomplete PHP class when serializing object in sessions

In ZF's bootstrap, the session was started before autoloading.

    /**
     * Make XXX_* classes available
     */
    protected function _initAutoloaders()
    {
        $loader = new Zend_Application_Module_Autoloader(array(
                    'namespace' => 'XXX',
                    'basePath' => APPLICATION_PATH
                ));
    }

    public function _initSession()
    {
        $config = $this->_config->custom->session;

        /**
         * For other settings, see the link below:
         * http://framework.zend.com/manual/en/zend.session.global_session_management.html
         */
        $sessionOptions = array(
            'name'             => $config->name,
            'gc_maxlifetime'   => $config->ttl,
            'use_only_cookies' => $config->onlyCookies,
//            'strict'           => true,
//            'path'             => '/',
        );

        // store session info in DB
        $sessDbConfig = array(
            'name'           => 'xxx_session',
            'primary'        => 'id',
            'modifiedColumn' => 'modified',
            'dataColumn'     => 'data',
            'lifetimeColumn' => 'lifetime'
        );

        Zend_Session::setOptions($sessionOptions);
        Zend_Session::setSaveHandler(new Zend_Session_SaveHandler_DbTable($sessDbConfig));
        Zend_Session::start();
    }

When I was getting the errors I was talking about, the method declaration was the other way around: _initSession() was first, then _initAutoloaders() - and this was the exact order ZF was processing them.

I'll test some more, but this seems to work (and logical). Thanks for all your suggestions.
