Detailed Description

Represents a title within MediaWiki.

Optionally may contain an interwiki designation or namespace.

Note: This class can fetch various kinds of data from the database; however, it does so inefficiently.; Consider using a TitleValue object instead. TitleValue is more lightweight and does not rely on global state or the database.

◆ getDefaultMessageText()

Title::getDefaultMessageText ( )

Get the default (plain) message contents for an page that overrides an interface message key.

Primary use cases:

Article:
- Show default when viewing the page. The Article::getSubstituteContent method displays the default message content, instead of the 'noarticletext' placeholder message normally used.
EditPage:
- Title of edit page. When creating an interface message override, the editor is told they are "Editing the page", instead of "Creating the page". (EditPage::setHeaders)
- Edit notice. The 'translateinterface' edit notice is shown when creating or editing a an interface message override. (EditPage::showIntro)
- Opening the editor. The contents of the localisation message are used as contents of the editor when creating a new page in the MediaWiki namespace. This simplifies the process for editors when "changing" an interface message by creating an override. (EditPage::getContentObject)
- Showing a diff. The left-hand side of a diff when an editor is previewing their changes before saving the creation of a page in the MediaWiki namespace. (EditPage::showDiff)
- Disallowing a save. When attempting to create a a MediaWiki-namespace page with the proposed content matching the interface message default, the save is rejected, the same way we disallow blank pages from being created. (EditPage::internalAttemptSave)
ApiEditPage:
- Default content, when using the 'prepend' or 'append' feature.
SkinTemplate:
- Label the create action as "Edit", if the page can be an override.

◆ getFullUrlForRedirect()

Title::getFullUrlForRedirect	(		$query = '',
			$proto = PROTO_CURRENT )

Get a url appropriate for making redirects based on an untrusted url arg.

This is basically the same as getFullUrl(), but in the case of external interwikis, we send the user to a landing page, to prevent possible phishing attacks and the like.

Note: Uses current protocol by default, since technically relative urls aren't allowed in redirects per HTTP spec, so this is not suitable for places where the url gets cached, as might pollute between https and non-https users.

See also: self::getLocalURL for the arguments.

Parameters

If a string is passed it will be interpreted as a deprecated variant argument and urlencoded into a variant= argument. This second query argument will be added to the $query The second parameter is deprecated since 1.19. Pass it as a key,value pair in the first parameter array instead.

◆ isValid()

Title::isValid ( )

Returns true if the title is valid, false if it is invalid.

Valid titles can be round-tripped via makeTitleSafe() and newFromText(). Invalid titles may get returned from makeTitle(), and it may be useful to allow them to exist, e.g. in order to process log entries about pages in namespaces that belong to extensions that are no longer installed.

Note: This method is relatively expensive. When constructing Title objects that need to be valid, use an instantiator method that is guaranteed to return valid titles, such as makeTitleSafe() or newFromText().

Returns: bool

◆ makeName()

static Title::makeName	(	$ns,
		$title,
		$fragment = '',
		$interwiki = '',

Parameters

int	$ns	Numerical representation of the namespace
string	$title	The DB key form the title
string	$fragment	The link fragment (after the "#")
string	$interwiki	The interwiki prefix
bool	$canonicalNamespace	If true, use the canonical name for $ns instead of the localized version.

Returns: string The prefixed form of the title

References $name, and $title.

◆ makeTitle()

static Title::makeTitle	(	$ns,
		$title,
		$fragment = '',
		$interwiki = '' )

static

Create a new Title from a namespace index and a DB key.

It's assumed that $ns and $title are safe, for instance when they came directly from the database or a special page name, not from user input.

No validation is applied. For convenience, spaces are normalized to underscores, so that e.g. user_text fields can be used directly.

Note: This method may return Title objects that are "invalid" according to the isValid() method. This is usually caused by configuration changes: e.g. a namespace that was once defined is no longer configured, or a character that was once allowed in titles is now forbidden.

Parameters

int	$ns	The namespace of the article
string	$title	The unprefixed database key form
string	$fragment	The link fragment (after the "#")
string	$interwiki	The interwiki prefix

Returns: Title The new object

References $t, and wfUrlencode().

◆ makeTitleSafe()

static Title::makeTitleSafe	(	$ns,
		$title,
		$fragment = '',
		$interwiki = '' )

static

Create a new Title from a namespace index and a DB key.

The parameters will be checked for validity, which is a bit slower than makeTitle() but safer for user-provided data.

Title objects returned by makeTitleSafe() are guaranteed to be valid, that is, they return true from the isValid() method. If no valid Title can be constructed from the input, this method returns null.

Parameters

int	$ns	The namespace of the article
string	$title	Database key form
string	$fragment	The link fragment (after the "#")
string	$interwiki	Interwiki prefix

Returns: Title|null The new object, or null on an error
