ajax Forms

[Clintonb]

I saw a new way of handling forms using javascript as an ajax object.  Instead of the form having a submit button, it has just a button with an onclick method that shows the followinf code :

 

new Ajax.Updater('container', 'processform.php', {asynchronous:true, parameters:Form.serialize('form'), onSuccess: endSend})

 

This script sends the form contents of form to a processform php script and i'm trying to do the same with my normal form.  I was confused by the function form.serialize('form') and i was wondering if someone could tell me why this is used?  If i used this with a php script do i call the values using $_POST['Var1'] or does the serialize send it in a way that needs specific server side processing?

 

Thanks in advance

form.serialize basically formats the output of the form as if you had hit the submit button like normal.  So at that point you can collect that data by using $_POST or $_POST['Var1'] or however you normally handle your POST data.
