Classes in Sessions

chariot

I've got the following two files:

pre_form.php
<?php
class my_class {
var $prop1 = "abc";
var $prop2 = "def";

function my_class() {
}

function getprop1() {
return $this->prop1;
}

}

session_start();
$norman = New my_class;
session_register( "norman" );
header( "Location: forms.php " );
?>

form.php
<?php
session_start();
if( is_object($norman) ) {
echo $norman->prop1;
} else {

echo "No";
}
?>

When I run pre_form.php it goes through its thing with no problem and jumps to form.php and then spits out the following:
"Fatal error: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition my_class of the object you are trying to operate on was loaded before the session was started in /home/chariot/public_html/test/sessions/forms.php on line 4"

If I change "echo $norman->prop1;" to "print_r(get_object_vars($norman));" I get:
Array
(
[__PHP_Incomplete_Class_Name] => my_class
[prop1] => abc
[prop2] => def
)

If I replace the "header(..." in form.php with "print_r(get_object_vars($norman));" I get the following:
Array
(
[prop1] => abc
[prop2] => def
)

Anyone know why my_class breaks after being passed through a session variable?

you have to include the class in form.php. basically, for this you should take just your class and put it in an include file. then have your scripts look like this:

class.inc:

<?
class my_class {
var $prop1 = "abc";
var $prop2 = "def";

function my_class() {
}

function getprop1() {
return $this->prop1;
}
}
?>

preform.php:

<?
include "class.inc";
session_start();
$norman = New my_class;
session_register( "norman" );
header( "Location: forms.php " );
?>

form.php

<?
include "class.inc";
session_start();
if( is_object($norman) ) {
echo $norman->prop1;
} else {
echo "No";
}
?>

you have to have the class in the script you are working in. if you don't and you try to use a method, the script cannot find it.

This happends because you've got to provide the Class Definition in Both files.
I suggest you to place the class definition on a separate file and then, include it on the other two files.
you also have to take in notice, that an objet passed as a session var, may or may not keep its Methods, depending on the PHP version you're running. Attributes remain, methods not always.

Bye.
