Detailed Description

Generic operation result class Has warning/error list, boolean status and arbitrary value.

"Good" means the operation was completed with no warnings or errors.

"OK" means the operation was partially or wholly completed.

An operation which is not OK should have errors so that the user can be informed as to what went wrong. Calling the fatal() function sets an error message and simultaneously switches off the OK flag.

The recommended pattern for Status objects is to return a Status object unconditionally, i.e. both on success and on failure – so that the developer of the calling code is reminded that the function can fail, and so that a lack of error-handling will be explicit.

Member Function Documentation

◆ __get()

Status::__get ( $name )

Backwards compatibility logic.

Parameters

string $name

Returns: mixed

Exceptions

RuntimeException

Definition at line 86 of file Status.php.

References StatusValue\getErrors(), and StatusValue\isOK().

◆ __set()

Status::__set	(		$name,
			$value )

Change operation result Backwards compatibility logic.

Parameters

string	$name
mixed	$value

Exceptions

RuntimeException

Definition at line 105 of file Status.php.

References StatusValue\$value, and StatusValue\setOK().

◆ __sleep()

Status::__sleep ( )

Don't save the callback when serializing, because Closures can't be serialized and we're going to clear it in __wakeup anyway.

Don't save the localizer, because it can be pretty much anything. Restoring it is the caller's responsibility (otherwise it will just fall back to the global request context).

Returns: array

Definition at line 381 of file Status.php.

References $keys.

◆ __wakeup()

Status::__wakeup ( )

Sanitize the callback parameter on wakeup, to avoid arbitrary execution.

Definition at line 389 of file Status.php.

◆ cleanParams()

Status::cleanParams ( array $params )

protected

Parameters

array $params

Returns: array

Definition at line 170 of file Status.php.

Referenced by getErrorMessage().

◆ getErrorMessage()

Status::getErrorMessage	(		$error,
			$lang = null )

protected

Return the message for a single error.

The code string can be used a message key with per-language versions. If $error is an array, the "params" field is a list of parameters for the message.

Parameters

array \| string	$error	Code string or (key: code string, params: string[]) map
string \| Language \| null	$lang	Language to use for processing messages

Returns: Message

References $lang, cleanParams(), and wfEscapeWikiText().

◆ getErrorMessageArray()

Status::getErrorMessageArray	(		$errors,
			$lang = null )

protected

Return an array with a Message object for each error.

Parameters

array	$errors
string \| Language \| null	$lang	Language to use for processing messages

Returns: Message[]

Definition at line 344 of file Status.php.

References StatusValue\$errors, $lang, and getErrorMessage().

Referenced by getMessage(), and getWikiText().

◆ getErrorsArray()

Status::getErrorsArray ( )

Get the list of errors (but not warnings)

Returns: array[] A list in which each entry is an array with a message key as its first element. The remaining array elements are the message parameters.

Deprecated: since 1.25

◆ getHTML()

Status::getHTML	(	$shortContext = false,
		$longContext = false,
		$lang = null )

Get the error message as HTML.

This is done by parsing the wikitext error message

Parameters

string \| bool	$shortContext	A short enclosing context message name, to be used when there is a single error
string \| bool	$longContext	A long enclosing context message name, for a list
string \| Language \| null	$lang	Language to use for processing messages

Returns: string

Definition at line 329 of file Status.php.

References $lang, ParserOutput\getText(), and getWikiText().

◆ getMessage()

Status::getMessage	(	$shortContext = false,
		$longContext = false,
		$lang = null )

Get a bullet list of the errors as a Message object.

$shortContext and $longContext can be used to wrap the error list in some text. $shortContext will be preferred when there is a single error; $longContext will be preferred when there are multiple ones. In either case, $1 will be replaced with the list of errors.

$shortContext is assumed to use $1 as an inline parameter: if there is a single item, it will not be made into a list; if there are multiple items, newlines will be inserted around the list. $longContext is assumed to use $1 as a standalone parameter; it will always receive a list.

If both parameters are missing, and there is only one error, no bullet will be added.

Parameters

string \| string[] \| bool	$shortContext	A message name or an array of message names.
string \| string[] \| bool	$longContext	A message name or an array of message names.
string \| Language \| StubUserLang \| null	$lang	Language to use for processing messages

Returns: Message

◆ getStatusValue()

Status::getStatusValue ( )

Returns the wrapped StatusValue object.

Returns: StatusValue

Since: 1.27

Definition at line 162 of file Status.php.

◆ getWarningsArray()

Status::getWarningsArray ( )

Get the list of warnings (but not errors)

Returns: array[] A list in which each entry is an array with a message key as its first element. The remaining array elements are the message parameters.

Deprecated: since 1.25

Definition at line 370 of file Status.php.

◆ getWikiText()

Status::getWikiText	(	$shortContext = false,
		$longContext = false,
		$lang = null )

Get the error list as a wikitext formatted list.

Parameters

string \| bool	$shortContext	A short enclosing context message name, to be used when there is a single error
string \| bool	$longContext	A long enclosing context message name, for a list
string \| Language \| StubUserLang \| null	$lang	Language to use for processing messages

Returns: string

◆ setMessageLocalizer()

Status::setMessageLocalizer ( MessageLocalizer $messageLocalizer )

Makes this Status object use the given localizer instead of the global one.

If it is an IContextSource or a ResourceLoader Context, it will also be used to determine the interface language.

Note: This setting does not survive serialization. That's usually for the best (there's no guarantee we'll still have the same localization settings after unserialization); it is the caller's responsibility to set the localizer again if needed.

Parameters

MessageLocalizer $messageLocalizer

Definition at line 126 of file Status.php.

◆ splitByErrorType()

Status::splitByErrorType ( )

Splits this Status object into two new Status objects, one which contains only the error messages, and one that contains the warnings, only.

The returned array is defined as: [ 0 => object(Status) # The Status with error messages, only 1 => object(Status) # The Status with warning messages, only ]

Returns: Status[]

Reimplemented from StatusValue.

Definition at line 141 of file Status.php.

◆ wrap()

static Status::wrap ( $sv )

static

Succinct helper method to wrap a StatusValue.

This is useful when formatting StatusValue objects:

$this->getOutput()->addHtml( Status::wrap( $sv )->getHTML() );

Status\getHTML

getHTML( $shortContext=false, $longContext=false, $lang=null)

Get the error message as HTML.

Definition Status.php:329

Parameters

StatusValue | Status $sv

Returns: Status
