Registers new options. Options allow the administrator to configure the behaviour of installed packages. The specified values are exposed as PHP constants.

Category Components

Each category is described as an <category> element with the mandatory attribute name.

<parent>

Optional

The category’s parent category.

<showorder>

Optional

Specifies the order of this option within the parent category.

<options>

Optional

The options element can contain a comma-separated list of options of which at least one needs to be enabled for the category to be shown to the administrator.

Option Components

Each option is described as an <option> element with the mandatory attribute name. The name is transformed into a PHP constant name by uppercasing it.

<categoryname>

The option’s category.

<optiontype>

The type of input to be used for this option. Valid types are defined by the wcf\system\option\*OptionType classes.

<defaultvalue>

The value that is set after installation of a package. Valid values are defined by the optiontype.

<validationpattern>

Optional

Defines a regular expression that is used to validate the value of a free form option (such as text).

<showorder>

Optional

Specifies the order of this option within the category.

<selectoptions>

Optional

Defined only for select, multiSelect and radioButton types.

Specifies a newline-separated list of selectable values. Each line consists of an internal handle, followed by a colon (:, U+003A), followed by a language item. The language item is shown to the administrator, the internal handle is what is saved and exposed to the code.

<enableoptions>

Optional

Defined only for boolean, select and radioButton types.

Specifies a comma-separated list of options which should be visually enabled when this option is enabled. A leading exclamation mark (!, U+0021) will disable the specified option when this option is enabled. For select and radioButton types the list should be prefixed by the internal selectoptions handle followed by a colon (:, U+003A).

This setting is a visual helper for the administrator only. It does not have an effect on the server side processing of the option.

<hidden>

Optional

If hidden is set to 1 the option will not be shown to the administrator. It still can be modified programmatically.

<options>

Optional

The options element can contain a comma-separated list of options of which at least one needs to be enabled for the option to be shown to the administrator.

<supporti18n>

Optional

Specifies whether this option supports localized input.

<requirei18n>

Optional

Specifies whether this option requires localized input (i.e. the administrator must specify a value for every installed language).

<*>

Optional

Additional fields may be defined by specific types of options. Refer to the documentation of these for further explanation.

Language Items

All relevant language items have to be put into the wcf.acp.option language item category.

Categories

If you install a category named example.sub, you have to provide the language item wcf.acp.option.category.example.sub, which is used when displaying the options. If you want to provide an optional description of the category, you have to provide the language item wcf.acp.option.category.example.sub.description. Descriptions are only relevant for categories whose parent has a parent itself, i.e. categories on the third level.

Options

If you install an option named module_example, you have to provide the language item wcf.acp.option.module_example, which is used as a label for setting the option value. If you want to provide an optional description of the option, you have to provide the language item wcf.acp.option.module_example.description.
