| 86 | * Object handling generic submission, CSRF protection, layout and |
| 87 | * other logic for UI forms in a reusable manner. |
| 88 | * |
| 89 | * In order to generate the form, the HTMLForm object takes an array |
| 90 | * structure detailing the form fields available. Each element of the |
| 91 | * array is a basic property-list, including the type of field, the |
| 92 | * label it is to be given in the form, callbacks for validation and |
| 93 | * 'filtering', and other pertinent information. |
| 94 | * |
| 95 | * Field types are implemented as subclasses of the generic HTMLFormField |
| 96 | * object, and typically implement at least getInputHTML, which generates |
| 97 | * the HTML for the input field to be placed in the table. |
| 98 | * |
| 99 | * You can find extensive documentation on the www.mediawiki.org wiki: |
| 100 | * - https://www.mediawiki.org/wiki/HTMLForm |
| 101 | * - https://www.mediawiki.org/wiki/HTMLForm/tutorial |
| 102 | * |
| 103 | * The constructor input is an associative array of $fieldname => $info, |
| 104 | * where $info is an Associative Array with any of the following: |
| 105 | * |
| 106 | * 'class' -- the subclass of HTMLFormField that will be used |
| 107 | * to create the object. *NOT* the CSS class! |
| 108 | * 'type' -- roughly translates into the <select> type attribute. |
| 109 | * if 'class' is not specified, this is used as a map |
| 110 | * through HTMLForm::$typeMappings to get the class name. |
| 111 | * 'default' -- default value when the form is displayed |
| 112 | * 'nodata' -- if set (to any value, which casts to true), the data |
| 113 | * for this field will not be loaded from the actual request. Instead, |
| 114 | * always the default data is set as the value of this field. |
| 115 | * 'id' -- HTML id attribute |
| 116 | * 'cssclass' -- CSS class |
| 117 | * 'csshelpclass' -- CSS class used to style help text |
| 118 | * 'dir' -- Direction of the element. |
| 119 | * 'options' -- associative array mapping raw HTML labels to values. |
| 120 | * Some field types support multi-level arrays. |
| 121 | * Overwrites 'options-message'. |
| 122 | * 'options-messages' -- associative array mapping message keys to values. |
| 123 | * Some field types support multi-level arrays. |
| 124 | * Overwrites 'options' and 'options-message'. |
| 125 | * 'options-messages-parse' -- Flag to parse the messages in 'options-messages'. |
| 126 | * 'options-message' -- message key or object to be parsed to extract the list of |
| 127 | * options (like 'ipbreason-dropdown'). |
| 128 | * 'label-message' -- message key or object for a message to use as the label. |
| 129 | * can be an array of msg key and then parameters to |
| 130 | * the message. |
| 131 | * 'label' -- alternatively, a raw text message. Overridden by |
| 132 | * label-message |
| 133 | * 'help-raw' -- message text for a message to use as a help text. |
| 134 | * 'help-message' -- message key or object for a message to use as a help text. |
| 135 | * can be an array of msg key and then parameters to |
| 136 | * the message. |
| 137 | * Overwrites 'help-messages' and 'help-raw'. |
| 138 | * 'help-messages' -- array of message keys/objects. As above, each item can |
| 139 | * be an array of msg key and then parameters. |
| 140 | * Overwrites 'help-raw'. |
| 141 | * 'help-inline' -- Whether help text (defined using options above) will be shown |
| 142 | * inline after the input field, rather than in a popup. |
| 143 | * Defaults to true. Only used by OOUI form fields. |
| 144 | * 'notices' -- Array of plain text notices to display below the input field. |
| 145 | * Only used by OOUI form fields. |
| 146 | * 'required' -- passed through to the object, indicating that it |
| 147 | * is a required field. |
| 148 | * 'size' -- the length of text fields |
| 149 | * 'filter-callback' -- a function name to give you the chance to |
| 150 | * massage the inputted value before it's processed. |
| 151 | * @see HTMLFormField::filter() |
| 152 | * 'validation-callback' -- a function name to give you the chance |
| 153 | * to impose extra validation on the field input. The signature should be |
| 154 | * as documented in {@see HTMLFormField::$mValidationCallback}. |
| 155 | * @see HTMLFormField::validate() |
| 156 | * 'name' -- By default, the 'name' attribute of the input field |
| 157 | * is "wp{$fieldname}". If you want a different name |
| 158 | * (eg one without the "wp" prefix), specify it here and |
| 159 | * it will be used without modification. |
| 160 | * 'hide-if' -- expression given as an array stating when the field |
| 161 | * should be hidden. The first array value has to be the |
| 162 | * expression's logic operator. Supported expressions: |
| 163 | * 'NOT' |
| 164 | * [ 'NOT', array $expression ] |
| 165 | * To hide a field if a given expression is not true. |
| 166 | * '===' |
| 167 | * [ '===', string $fieldName, string $value ] |
| 168 | * To hide a field if another field identified by |
| 169 | * $field has the value $value. |
| 170 | * '!==' |
| 171 | * [ '!==', string $fieldName, string $value ] |
| 172 | * Same as [ 'NOT', [ '===', $fieldName, $value ] |
| 173 | * 'OR', 'AND', 'NOR', 'NAND' |
| 174 | * [ 'XXX', array $expression1, ..., array $expressionN ] |
| 175 | * To hide a field if one or more (OR), all (AND), |
| 176 | * neither (NOR) or not all (NAND) given expressions |
| 177 | * are evaluated as true. |
| 178 | * The expressions will be given to a JavaScript frontend |
| 179 | * module which will continually update the field's |
| 180 | * visibility. |
| 181 | * 'disable-if' -- expression given as an array stating when the field |
| 182 | * should be disabled. See 'hide-if' for supported expressions. |
| 183 | * The 'hide-if' logic would also disable fields, you don't need |
| 184 | * to set this attribute with the same condition manually. |
| 185 | * You can pass both 'disabled' and this attribute to omit extra |
| 186 | * check, but this would function only for not 'disabled' fields. |
| 187 | * 'section' -- A string name for the section of the form to which the field |
| 188 | * belongs. Subsections may be added using the separator '/', e.g.: |
| 189 | * 'section' => 'section1/subsection1' |
| 190 | * More levels may be added, e.g.: |
| 191 | * 'section' => 'section1/subsection2/subsubsection1' |
| 192 | * The message key for a section or subsection header is built from |
| 193 | * its name and the form's message prefix (if present). |
| 194 | * |
| 195 | * Since 1.20, you can chain mutators to ease the form generation: |
| 196 | * @par Example: |
| 197 | * @code |
| 198 | * $form = new HTMLForm( $someFields, $this->getContext() ); |
| 199 | * $form->setMethod( 'get' ) |
| 200 | * ->setWrapperLegendMsg( 'message-key' ) |
| 201 | * ->prepareForm() |
| 202 | * ->displayForm( '' ); |
| 203 | * @endcode |
| 204 | * Note that you will have prepareForm and displayForm at the end. Other |
| 205 | * method calls done after that would simply not be part of the form :( |
| 206 | * |
| 207 | * @stable to extend |
