84 | * Object handling generic submission, CSRF protection, layout and |
85 | * other logic for UI forms in a reusable manner. |
86 | * |
87 | * In order to generate the form, the HTMLForm object takes an array |
88 | * structure detailing the form fields available. Each element of the |
89 | * array is a basic property-list, including the type of field, the |
90 | * label it is to be given in the form, callbacks for validation and |
91 | * 'filtering', and other pertinent information. |
92 | * |
93 | * Field types are implemented as subclasses of the generic HTMLFormField |
94 | * object, and typically implement at least getInputHTML, which generates |
95 | * the HTML for the input field to be placed in the table. |
96 | * |
97 | * You can find extensive documentation on the www.mediawiki.org wiki: |
98 | * - https://www.mediawiki.org/wiki/HTMLForm |
99 | * - https://www.mediawiki.org/wiki/HTMLForm/tutorial |
100 | * |
101 | * The constructor input is an associative array of $fieldname => $info, |
102 | * where $info is an Associative Array with any of the following: |
103 | * |
104 | * 'class' -- the subclass of HTMLFormField that will be used |
105 | * to create the object. *NOT* the CSS class! |
106 | * 'type' -- roughly translates into the <select> type attribute. |
107 | * if 'class' is not specified, this is used as a map |
108 | * through HTMLForm::$typeMappings to get the class name. |
109 | * 'default' -- default value when the form is displayed |
110 | * 'nodata' -- if set (to any value, which casts to true), the data |
111 | * for this field will not be loaded from the actual request. Instead, |
112 | * always the default data is set as the value of this field. |
113 | * 'id' -- HTML id attribute |
114 | * 'cssclass' -- CSS class |
115 | * 'csshelpclass' -- CSS class used to style help text |
116 | * 'dir' -- Direction of the element. |
117 | * 'options' -- associative array mapping raw HTML labels to values. |
118 | * Some field types support multi-level arrays. |
119 | * Overwrites 'options-message'. |
120 | * 'options-messages' -- associative array mapping message keys to values. |
121 | * Some field types support multi-level arrays. |
122 | * Overwrites 'options' and 'options-message'. |
123 | * 'options-messages-parse' -- Flag to parse the messages in 'options-messages'. |
124 | * 'options-message' -- message key or object to be parsed to extract the list of |
125 | * options (like 'ipbreason-dropdown'). |
126 | * 'label-message' -- message key or object for a message to use as the label. |
127 | * can be an array of msg key and then parameters to |
128 | * the message. |
129 | * 'label' -- alternatively, a raw text message. Overridden by |
130 | * label-message |
131 | * 'help' -- message text for a message to use as a help text. |
132 | * 'help-message' -- message key or object for a message to use as a help text. |
133 | * can be an array of msg key and then parameters to |
134 | * the message. |
135 | * Overwrites 'help-messages' and 'help'. |
136 | * 'help-messages' -- array of message keys/objects. As above, each item can |
137 | * be an array of msg key and then parameters. |
138 | * Overwrites 'help'. |
139 | * 'help-inline' -- Whether help text (defined using options above) will be shown |
140 | * inline after the input field, rather than in a popup. |
141 | * Defaults to true. Only used by OOUI form fields. |
142 | * 'notices' -- Array of plain text notices to display below the input field. |
143 | * Only used by OOUI form fields. |
144 | * 'required' -- passed through to the object, indicating that it |
145 | * is a required field. |
146 | * 'size' -- the length of text fields |
147 | * 'filter-callback' -- a function name to give you the chance to |
148 | * massage the inputted value before it's processed. |
149 | * @see HTMLFormField::filter() |
150 | * 'validation-callback' -- a function name to give you the chance |
151 | * to impose extra validation on the field input. |
152 | * @see HTMLFormField::validate() |
153 | * 'name' -- By default, the 'name' attribute of the input field |
154 | * is "wp{$fieldname}". If you want a different name |
155 | * (eg one without the "wp" prefix), specify it here and |
156 | * it will be used without modification. |
157 | * 'hide-if' -- expression given as an array stating when the field |
158 | * should be hidden. The first array value has to be the |
159 | * expression's logic operator. Supported expressions: |
160 | * 'NOT' |
161 | * [ 'NOT', array $expression ] |
162 | * To hide a field if a given expression is not true. |
163 | * '===' |
164 | * [ '===', string $fieldName, string $value ] |
165 | * To hide a field if another field identified by |
166 | * $field has the value $value. |
167 | * '!==' |
168 | * [ '!==', string $fieldName, string $value ] |

170 | * 'OR', 'AND', 'NOR', 'NAND' |
171 | * [ 'XXX', array $expression1, ..., array $expressionN ] |
172 | * To hide a field if one or more (OR), all (AND), |
173 | * neither (NOR) or not all (NAND) given expressions |
174 | * are evaluated as true. |
175 | * The expressions will be given to a JavaScript frontend |
176 | * module which will continually update the field's |
177 | * visibility. |
178 | * 'disable-if' -- expression given as an array stating when the field |
179 | * should be disabled. See 'hide-if' for supported expressions. |
180 | * The 'hide-if' logic would also disable fields, you don't need |
181 | * to set this attribute with the same condition manually. |
182 | * You can pass both 'disabled' and this attribute to omit extra |
183 | * check, but this would function only for not 'disabled' fields. |
184 | * 'section' -- A string name for the section of the form to which the field |
185 | * belongs. Subsections may be added using the separator '/', e.g.: |
186 | * 'section' => 'section1/subsection1' |
187 | * More levels may be added, e.g.: |
188 | * 'section' => 'section1/subsection2/subsubsection1' |
189 | * The message key for a section or subsection header is built from |
190 | * its name and the form's message prefix (if present). |
191 | * |
192 | * Since 1.20, you can chain mutators to ease the form generation: |
193 | * @par Example: |
194 | * @code |
195 | * $form = new HTMLForm( $someFields, $this->getContext() ); |
196 | * $form->setMethod( 'get' ) |
197 | * ->setWrapperLegendMsg( 'message-key' ) |
198 | * ->prepareForm() |
199 | * ->displayForm( '' ); |
200 | * @endcode |
201 | * Note that you will have prepareForm and displayForm at the end. Other |
202 | * method calls done after that would simply not be part of the form :( |
203 | * |
204 | * @stable to extend |
