00566: Allow value defaults for input form controls
Description: This entry simply notes that Pm is planning to add an $InputValues variable that sets the default values to be used for various controls using the Forms markup.
In particular, setting
$InputValues['xyz'] = 'alpha bravo';
will mean that any input form control with the name 'xyz' will use 'alpha bravo' as its default value (in absence of any value= option).
A script can easily do
$InputValues = array_merge((array)$InputValues, $_REQUEST)
to say "default all form controls to the values that came from the last request". Similarly, a script could load default values for form controls from a database or other source.
As long as you're adding this capability to forms.php, how about adding a parameter to the (:input form:) tag that will set the contents of the form as shown above?
For example, (:input form values=get:) would fill the form only with $_GET values, values=post with $_POST values, values=cookie with $_COOKIE values, and values=request with $_REQUEST (which is all three). Just a thought.

I agree that some way to get values from $_GET, $_POST, etc should be part of core (:input form ...:). I think values submitted should automatically become available somehow in the page itself (via PV or PTV or something).
Until it's available in core, check out Cookbook.ProcessForm.
