*
|
|
* There is quite some logic in this field
|
|
* 1. store the changes to the field (tupe, name, label, default text)
|
|
* 2. remove the options and the choices of the users from the database that no longer occur in the form field 'possible values'. We should only remove
|
|
* the options (and choices) that do no longer have to appear. We cannot remove all options and choices because if you remove them all
|
|
* and simply re-add them all then all the user who have already filled this form will loose their selected value.
|
|
* 3. we add the options that are newly added
|
|
*
|
|
* @example current options are a;b;c and the user changes this to a;b;x (removing c and adding x)
|
|
* we first remove c (and also the entry in the option_value table for the users who have chosen this)
|
|
* we then add x
|
|
* a and b are neither removed nor added
|
|
*
|
|
* @param integer $fieldid the id of the field we are editing
|
|
* @param string $fieldvarname the internal variable name of the field
|
|
* @param int $fieldtype the type of the field
|
|
* @param string $fieldtitle the title of the field
|

* @param string $fielddefault the default value of the field

* @param string $fieldoptions Optional comma-separated list of options to provide for select and radio
