Použití

Parametry

Parametr/Možnost	Popis
$user	Uživatel, jehož předvolby se upravují
&$preferences	Pole popisu předvoleb, které má být přiváděno do objektu HTMLForm

Karty a sekce

Klíč pole section určuje, která karta a sekce Preferences obsahuje vaše preference. If your section value is foo/bar, this means your preference will appear on the foo tab (named by system message prefs-foo) within the bar section (named by system message prefs-bar). If no such tab or section exists, it is created automatically.

Supported types

Visible types

The type can take on various values found in the HTMLForm::$typeMappings array in the file includes/htmlform/HTMLForm.php, including info, multiselect, radio, etc.

Most preferences are stored in the same format as is used by the HTMLFormField, but in the case of 'type' => 'usersmultiselect' a transformation should be carried out from a newline-separated list of usernames (which is what the form widget works with) and a newline-separated list of user IDs (which is what gets stored in the database). See the treatment of email-blacklist (in core) or echo-notifications-blacklist (in Echo ) for examples of this.

Floats

For float types, you can set min and max, which will be validated on save.

API preferences

API preferences use type api. They are not displayed in Special:Preferences. They are usually set via custom front-end interfaces that call the API.

Note that you should not use 'type' => 'hidden' for API preferences (that type exists for HTML forms, not preferences).

Default preferences

To set the default value for a preference (i.e. the value that is set for a new user that hasn't customized their preferences yet), add the setting to the $wgDefaultUserOptions global variable. Use the same key name as you use for $preferences in the hook.

Alternatively, if you're writing an extension, you can add to the DefaultUserOptions section of the file extensions.json.
