Uploads: $wgCheckFileExtensions
Check if the file extension is allowed on upload.
Introduced in version: 1.2.0
Removed in version: still in use
Allowed values: (boolean)
Default value: true
Other settings: Alphabetical | By function

Details[edit]

If true, all uploaded files will have their file extension checked, depending on various configuration settings (see below), to determine whether the upload will be allowed.

If false, most file extension checks will not take place. In this case, almost all file uploads will be allowed.

Warning Warning: Setting this to false is insecure for public wikis.


MediaWiki version: 1.13

In version 1.11.1, there appears to be a bug that prevents this setting from actually working. (SpecialUpload.php line 353 isn't checking the value of this variable like it should.) Due to this, it is unclear from the code whether $wgCheckFileExtensions was intended to override $wgFileBlacklistManual:$wgFileBlacklist. The $wgStrictFileExtensionsManual:$wgStrictFileExtensions variable may have the desired effect. This bug was corrected in version 1.13.0 (task T16220).
