Extension:MediaUploader/Configuration/Details

MediaUploader has two very powerful features that allow you to build almost arbitrary forms for users and translate them into wikitext:
 * The ability to freely configure and reorder the fields in the Describe step (configured in the  section).
 * Setting up transformations from user input into wikitext (configured in the  section).

section
This section configures the fields shown in the Describe step. All fields shown there by default can be reordered or removed, and new ones can be added. Each field must have a unique key, such as. This key is later used for referring to the field's value when building the wikitext of the page (see the  section).

This section is simply a mapping from field key to field descriptor object. What settings can be configured for each field depends on the field type (see subsections below the example).


 * Default value – first two fields

Common field settings
These settings can be used on any field type.


 *   (string) – required. Must be one of the available types listed below.
 *   (integer) – required. Integer number indicating the order in which the fields should appear in the form, lowest to highest. The numbers don't have to be sequential (so you can have missing values in between).
 *   (string, parsed) – required. The main label of the field, shown in bold. The value of this setting is parsed.
 * (string, parsed) – optional. Help text displayed above the field, explaining the user how to use it. The value of this setting is parsed.
 * (string) – optional. This sets whether the user is forced to fill the field, is recommended to do that, or is completely free to decide. This field has three possible values:
 * – the user cannot progress without filling out this field.
 * – if the user hasn't filled out this field, they will be prompted before progressing further. The user can dismiss the prompt.
 * (default) – the user is not forced or prompted to fill out the field.
 * (boolean) – optional. Whether the field is visible to the user or not. The default is false.
 * (boolean) – optional. Whether the field can be edited by the user or not. The default is true.
 * (boolean) – optional. Whether the field should be moved to the bottom collapsible section titled by default Add location and more information... Use this for less important fields that you don't expect the users to use often. The default is false.
 * – default value for the field. If the field is  and not , the user can modify this default value. The type of this setting depends on the field type (see below).

Field types

 *   – simple one-line text field. Additional settings:
 * (string) – default content of the field
 * (integer) – minimum length in characters for user's input in this field
 * (integer) – maximum length in characters for user's input in this field
 * (boolean) – whether to try to automatically fill this field with the image's description extracted from metadata.
 *   – same as, but appears as a multi-line text field.
 *   – multi-line textbox with a language dropdown. Additional settings:
 * (map) – map specifying the default language and the default text.
 * Fields:,  . Both fields are mandatory.
 * The language should be a valid ISO 646 language code.
 * Example:
 * (integer) – same as in the  field type
 * (integer) – same as in the  field type
 *   – multiple-valued, multi-line textbox. For each value, a different language can be selected. This is useful in multilingual wikis (such as Wikimedia Commons), where you want to allow users to describe the file in multiple languages. Additional settings:
 * (array of maps) – an integer-indexed array, where each items corresponds to one language-text pair in the input. Each item in the array is configured just as the default value for the  field.
 * Example:
 * (integer) – same as in the  field type
 * (integer) – same as in the  field type
