/**
|
|
* Set of radio buttons designed to emulate a dropdown.
|
|
* It even uses the same constructor as a dropdown field.
|
|
*
|
|
* This field allows you to ensure that a form element is submitted is not optional and is part of a fixed set of
|
|
* data. This field uses the input type of radio. It's a direct subclass of {@link DropdownField},
|
|
* so the constructor and arguments are in the same format.
|
|
*
|
|
* <b>Usage</b>
|
|
*
|
|
* <code>
|
|
* new OptionsetField(
|
|
* $name = "Foobar",
|
|
* $title = "FooBar's optionset",
|
|
* $source = array(
|
|
* "1" => "Option 1",
|
|
* "2" => "Option 2",
|
|
* "3" => "Option 3",
|
|
* "4" => "Option 4",
|
|
* "5" => "Option 5"
|
|
* ),
|
|
* $value = "1"
|
|
* );
|
|
* </code>
|
|
*
|
|
* You can use the helper functions on data object set to create the source array. eg:
|
|
*
|
|
* <code>
|
|
* //Database request for the object
|
|
* $myDoSet = DataObject::get("FooBars","");
|
|
* if($myDoSet){
|
|
* // This returns an array of ID => Title
|
|
* $map = $myDoSet->toDropDownMap();
|
|
*
|
|
* // Instantiate the OptionsetField
|
|
* $fieldset = new Fieldset(
|
|
* new OptionsetField(
|
|
* $name = "Foobar",
|
|
* $title = "FooBar's optionset",
|
|
* $source = $map,
|
|
* $value = $map[0]
|
|
* )
|
|
* );
|
|
* }
|
|
*
|
|
* // Pass the fields to the form constructor. etc
|
|
* </code>
|
|
*
|
|
* @see CheckboxSetField for multiple selections through checkboxes instead.
|
|
* @see DropdownField for a simple <select> field with a single element.
|
|
* @see TreeDropdownField for a rich and customizeable UI that can visualize a tree of selectable elements
|
|
*
|
|
* @package forms
|
|
* @subpackage fields-basic
