Media Provider Package Installation Plugin#

Media providers are responsible to detect and convert links to a 3rd party service inside messages.

Components#

Each item is described as a <provider> element with the mandatory attribute name that should equal the lower-cased provider name. If a provider provides multiple components that are (largely) unrelated to each other, it is recommended to use a dash to separate the name and the component, e. g. youtube-playlist.

<title>#

The title is displayed in the administration control panel and is only used there, the value is neither localizable nor is it ever exposed to regular users.

<regex>#

The regular expression used to identify links to this provider, it must not contain anchors or delimiters. It is strongly recommended to capture the primary object id using the (?P<ID>...) group.

<className>#

<className> and <html> are mutually exclusive.

PHP-Callback-Class that is invoked to process the matched link in case that additional logic must be applied that cannot be handled through a simple replacement as defined by the <html> element.

The callback-class must implement the interface \wcf\system\bbcode\media\provider\IBBCodeMediaProvider.

<html>#

<className> and <html> are mutually exclusive.

Replacement HTML that gets populated using the captured matches in <regex>, variables are accessed as {$VariableName}. For example, the capture group (?P<ID>...) is accessed using {$ID}.
