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 88 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 107 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 432 of file Status.php.

References $keys.

◆ __wakeup()

Status::__wakeup ( )

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

Definition at line 440 of file Status.php.

◆ cleanParams()

Status::cleanParams ( array $params)
protected
Parameters
array$params
Returns
array

Definition at line 172 of file Status.php.

◆ 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$errorCode string or (key: code string, params: string[]) map
string | Language | StubUserLang | null$langLanguage to use for processing messages
Returns
Message

◆ getErrorMessageArray()

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

Return an array with a Message object for each error.

Parameters
array$errors
string | Language | StubUserLang | null$langLanguage to use for processing messages
Returns
Message[]

Definition at line 395 of file Status.php.

References $lang.

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 | false$shortContextA short enclosing context message name, to be used when there is a single error
string | false$longContextA long enclosing context message name, for a list
string | Language | StubUserLang | null$langLanguage to use for processing messages
Returns
string

Definition at line 380 of file Status.php.

References $lang, and ParserOutput\getText().

◆ 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[] | false$shortContextA message name or an array of message names.
string | string[] | false$longContextA message name or an array of message names.
string | Language | StubUserLang | null$langLanguage to use for processing messages
Returns
Message

◆ getPsr3MessageAndContext()

Status::getPsr3MessageAndContext ( )

Try to convert the status to a PSR-3 friendly format.

The output will be similar to getWikiText( false, false, 'en' ), but message parameters will be extracted into the context array with parameter names 'parameter1' etc. when possible.

Returns
array A pair of (message, context) suitable for passing to a PSR-3 logger.

Definition at line 294 of file Status.php.

◆ getStatusValue()

Status::getStatusValue ( )

Returns the wrapped StatusValue object.

Returns
StatusValue
Since
1.27

Definition at line 164 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

◆ getWikiText()

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

Get the error list as a wikitext formatted list.

Parameters
string | false$shortContextA short enclosing context message name, to be used when there is a single error
string | false$longContextA long enclosing context message name, for a list
string | Language | StubUserLang | null$langLanguage 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 128 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 143 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() );
getHTML( $shortContext=false, $longContext=false, $lang=null)
Get the error message as HTML.
