session objects and functions

Anon

Hi,

I am sure this may have been covered before but i searched for and could not find it.

what i want to know is how do i add an object to a session and have that object available on further pages? i want the fields and functions available. i have tried a very simple test but it seems as if the functions dont get carried over. do you have to serialise the class? is there a special setting that you have to set in php.ini for session objects?

if someone could give me some very simple code to try out as well would be greatly appreciated.

Thank you.

There is no way to pass the entire object, only properties. You'll have to redefine the class and instantiate the object, then call session_start() to import the properties to the new object.

Hi Rod,

Thanks for your reply. i tried what you have said and i am still getting an error. have a look at these files:

<?
//filename: CategoryFormHandler_cmpt.class
class CategoryFormHandler_cmpt {
var $parent;
var $name;
var $handleFunction;
function setFields(){
$this->parent = $parent;
$this->name = $name;
$this->handleFunction = $handleFunction;
}
}
?>

<?
//form.php
include_once("CategoryFormHandler_cmpt.class");
$CategoryFormHandler = new CategoryFormHandler_cmpt;
session_register("CategoryFormHandler");
?>
<form action="process_form.php" method=post>
<input type=text name="parent">
<input type=text name="name">
<input type=text name="handleFunction">
<input type=submit>
</form>

<?
//filename: process_form.php
include_once("CategoryFormHandler_cmpt.class");
$CategoryFormHandler = new CategoryFormHandler_cmpt;
session_start();
$CategoryFormHadnler->setFields();
print $parent."<br>";
print $name."<br>";
print $handleFunction."<p>";

?>

according to what you have said, this should work right? but i still get an error message saying that the function is being called to a non function. it seems really strange because there is no error on the instantiation of the object but when you try to call a method it complains that the object is not an object!!

any ideas?

Thanks
