Format: function ZAPinput($f, $v, $formkey='')

Explanation: This function is called by the ZAP input markup, inserting the field name into $f, the value into $v, and the form key (if it is set) into $formkey.

The field=value pair is added to the ZAP SESSION array with the appropriate key value. After the session variables are set, the function returns, with no output sent to the page.
