3 * Object handling generic submission, CSRF protection, layout and
4 * other logic for UI forms. in a reusable manner.
6 * In order to generate the form, the HTMLForm object takes an array
7 * structure detailing the form fields available. Each element of the
8 * array is a basic property-list, including the type of field, the
9 * label it is to be given in the form, callbacks for validation and
10 * 'filtering', and other pertinent information.
12 * Field types are implemented as subclasses of the generic HTMLFormField
13 * object, and typically implement at least getInputHTML, which generates
14 * the HTML for the input field to be placed in the table.
16 * The constructor input is an associative array of $fieldname => $info,
17 * where $info is an Associative Array with any of the following:
19 * 'class' -- the subclass of HTMLFormField that will be used
20 * to create the object. *NOT* the CSS class!
21 * 'type' -- roughly translates into the <select> type attribute.
22 * if 'class' is not specified, this is used as a map
23 * through HTMLForm::$typeMappings to get the class name.
24 * 'default' -- default value when the form is displayed
25 * 'id' -- HTML id attribute
26 * 'cssclass' -- CSS class
27 * 'options' -- varies according to the specific object.
28 * 'label-message' -- message key for a message to use as the label.
29 * can be an array of msg key and then parameters to
31 * 'label' -- alternatively, a raw text message. Overridden by
33 * 'help-message' -- message key for a message to use as a help text.
34 * can be an array of msg key and then parameters to
36 * Overwrites 'help-messages'.
37 * 'help-messages' -- array of message key. As above, each item can
38 * be an array of msg key and then parameters.
39 * Overwrites 'help-message'.
40 * 'required' -- passed through to the object, indicating that it
41 * is a required field.
42 * 'size' -- the length of text fields
43 * 'filter-callback -- a function name to give you the chance to
44 * massage the inputted value before it's processed.
45 * @see HTMLForm::filter()
46 * 'validation-callback' -- a function name to give you the chance
47 * to impose extra validation on the field input.
48 * @see HTMLForm::validate()
49 * 'name' -- By default, the 'name' attribute of the input field
50 * is "wp{$fieldname}". If you want a different name
51 * (eg one without the "wp" prefix), specify it here and
52 * it will be used without modification.
