PHP Session with an Incomplete Object

Question

I'm getting an error I don't know how to fix so I wondering if I could get some help. This is the error ``` Fatal error: process_form() [function.process-form]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Template" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /home/twinmeddev/html/template_add.php on line 44 ``` I get this error in the process_form() function. So what I get out of this is that, its thinking I didn't load the class for the template. Which in fact I did up at the top. The include 'inc/item.class.php'; Do I have to re-include it in the function? Here's the code for the particular page with the error. You can see I have everything included like it should be. Where have I gone wrong? ```

Accepted Answer

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: ``` ``` and ``` ``` 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: ``` ``` While this would be correct: ``` ``` 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).
