I can't understand what ghost is and how to use it. Could you please give an example? I searched the forum but I couldn't derive a meaning.
Hi jdran,
The 'ghost' setting lets you set a default value for a radio, checkbox or checkbox group element. The problem with these elements is that if nothing is checked then *nothing* is submitted. The element is not included at all in the submitted data. This can cause a problem if you are using the form to edit an existing record and there is a previously saved value for the element as it won't be updated. Setting a ghost value - as an empty value, or something specific - ensures that a value is submitted and therefore the record will be updated.
The ghost works by adding a hidden input before the element with the same name. Because only the last of two elements with the same name is submitted this means that the ghost is over-written by any actual selection.
