function _form_element_triggered_scripted_submission
_form_element_triggered_scripted_submission($element, &$form_state)
Detects if an element triggered the form submission via Ajax.
This detects button or non-button controls that trigger a form submission via Ajax or some other scriptable environment. These environments can set the special input key '_triggering_element_name' to identify the triggering element. If the name alone doesn't identify the element uniquely, the input key '_triggering_element_value' may also be set to require a match on element value. An example where this is needed is if there are several buttons all named 'op', and only differing in their value.
