I am trying to create a simple form using your component (great component by the way!) and need to know how to get the page to post back to itself

<form action="WHAT GOES HERE">

Also...how would I link to the page and pass in extra parameters

Thanks...I am sure you have probably already answered these questions...but I couldn't find them

Figured out my first question...needed to supply the variables as hidden inputs to have them pass

for example

<form action="index.php">
<input type="hidden" name="option" value="com_php">
<input type="hidden" name="Itemid" value="54">

Yes, you have to pass them as hidden form fields.

You don't have to hard code the Itemid value, it is always equal to:

$Itemid = JRequest::getParam('Itemid');

or in legacy mode (Joomla1.0):

$Itemid = mosGetParam($_REQUEST, 'Itemid');
