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.

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.

References $keys.

Status::__wakeup

(

)

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

Parameters

array

$params

Returns

array

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	$lang	Language to use for processing messages

Returns

Message

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

protected

Return an array with a Message object for each error.

Parameters

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

Returns

Message[]

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

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

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	$lang	Language to use for processing messages

Returns

Message
