◆ doesWrites()

MediaWiki\Specials\SpecialPageLanguage::doesWrites ( )

Indicates whether POST requests to this special page require write access to the wiki.

Subclasses must override this method to return true if any of the operations that they perform on POST requests are not "safe" per RFC 7231 section 4.2.1. A subclass's operation is "safe" if it is essentially read-only, i.e. the client does not request nor expect any state change that would be observable in the responses to future requests.

Implementations of this method must always return the same value, regardless of the parameters passed to the constructor or system state.

When handling GET/HEAD requests, subclasses should only perform "safe" operations. Note that some subclasses might only perform "safe" operations even for POST requests, particularly in the case where large input parameters are required.

Stability: stable: to override

Returns: bool
