◆ __set_state()

static MediaWiki\Auth\ButtonAuthenticationRequest::__set_state ( $data )

Parameters

array $data

Returns: AuthenticationRequest|static

◆ getFieldInfo()

MediaWiki\Auth\ButtonAuthenticationRequest::getFieldInfo ( )

Fetch input field info.

The field info is an associative array mapping field names to info arrays. The info arrays have the following keys:

type: (string) Type of input. Types and equivalent HTML widgets are:
- string: <input type="text">
- password: <input type="password">
- select: <select>
- checkbox: <input type="checkbox">
- multiselect: More a grid of checkboxes than <select multi>
- button: <input type="submit"> (uses 'label' as button text)
- hidden: Not visible to the user, but needs to be preserved for the next request
- null: No widget, just display the 'label' message.
options: (array) Maps option values to Messages for the 'select' and 'multiselect' types.
value: (string) Value (for 'null' and 'hidden') or default value (for other types).
label: (Message) Text suitable for a label in an HTML form
help: (Message) Text suitable as a description of what the field is
optional: (bool) If set and truthy, the field may be left empty
sensitive: (bool) If set and truthy, the field is considered sensitive. Code using the request should avoid exposing the value of the field.
skippable: (bool) If set and truthy, the client is free to hide this field from the user to streamline the workflow. If all fields are skippable (except possibly a single button), no user interaction is required at all.

All AuthenticationRequests are populated from the same data, so most of the time you'll want to prefix fields names with something unique to the extension/provider (although in some cases sharing the field with other requests is the right thing to do, e.g. for a 'password' field).

Returns: array As above -return array<string,array{type:string,options?:array,value?:string,label:Message,help:Message,optional?:bool,sensitive?:bool,skippable?:bool}>

◆ getRequestByName()

static MediaWiki\Auth\ButtonAuthenticationRequest::getRequestByName	(	array	$reqs,
			$name )

static

Fetch a ButtonAuthenticationRequest or subclass by name.

Parameters

AuthenticationRequest[]	$reqs	Requests to search
string	$name	Name to look for

Returns: ButtonAuthenticationRequest|null Returns null if there is not exactly one matching request.

◆ getUniqueId()

MediaWiki\Auth\ButtonAuthenticationRequest::getUniqueId ( )

Supply a unique key for deduplication.

When the AuthenticationRequests instances returned by the providers are merged, the value returned here is used for keeping only one copy of duplicate requests.

Subclasses should override this if multiple distinct instances would make sense, i.e. the request class has internal state of some sort.

This value might be exposed to the user in web forms so it should not contain private information.
