Passing objects!!!

[Anon]

I need to pass some objects I have created in a form to the form handler. How can I do that?

Can I assign it as a hidden variable in the html form and send it across?

Regards,
Malai.

No you cannot.

An object has methods and properties. you can only send the properties as seperate values. You cannot send the methods (which woudl make no sense anyway).

You can however store objects in sessions.
This is effectively the same as putting the entire object into hidden form fields.

Read more about sessions in the manual.

You CAN pass objects across pages. It is not perfect but does work.
You need to serialize the object (http://www.php.net/manual/en/function.serialize.php)
then you need to urlencode it (http://www.php.net/manual/en/function.urlencode.php)
then put it in the hidden variable and submit.

On the next page you need to urldecode it (some servers automatically urldecode it so you might not need too) then unserialize it.
Also check this page out http://www.php.net/manual/en/language.oop.magic-functions.php
if you need to do things before and after you serialize it.

"You CAN pass objects across pages."

Like I said, you can only pass the properties, not the methods. So NO your CAN'T send an object accress pages.
