/**
|
|
* Displays a set of checkboxes as a logical group.
|
|
*
|
|
* ASSUMPTION -> IF you pass your source as an array, you pass values as an array too. Likewise objects are handled
|
|
* the same.
|
|
*
|
|
* Example:
|
|
* <code>
|
|
* new CheckboxSetField(
|
|
* $name = "topics",
|
|
* $title = "I am interested in the following topics",
|
|
* $source = array(
|
|
* "1" => "Technology",
|
|
* "2" => "Gardening",
|
|
* "3" => "Cooking",
|
|
* "4" => "Sports"
|
|
* ),
|
|
* $value = "1"
|
|
* );
|
|
* </code>
|
|
*
|
|
* <b>Saving</b>
|
|
* The checkbox set field will save its data in one of ways:
|
|
* - If the field name matches a many-many join on the object being edited, that many-many join will be updated to
|
|
* link to the objects selected on the checkboxes. In this case, the keys of your value map should be the IDs of
|
|
* the database records.
|
|
* - If the field name matches a database field, a comma-separated list of values will be saved to that field. The
|
|
* keys can be text or numbers.
|
|
*
|
|
* @todo Document the different source data that can be used
|
|
* with this form field - e.g ComponentSet, ArrayList,
|
|
* array. Is it also appropriate to accept so many different
|
|
* types of data when just using an array would be appropriate?
