Putting: application/msword doc xls ppt works for getting the files into the wiki, but causes the wrong mime types to be sent back when the user accesses the file. What I've found to work (and please let me know if there is a better way), is to send the correct mime type out depending on the extension: --- MimeMagic.php.old 2008-01-29 16:15:59.000000000 -0600 +++ MimeMagic.php 2008-01-29 16:15:35.000000000 -0600 @@ -497,6 +497,21 @@ } + //BEGIN CUSTOMIZATION + # New excel files have the same magic number as msword files + if ( $mime == "application/msword" ) { + $i = strrpos( $file, '.' ); + $e = strtolower( $i ? substr( $file, $i + 1 ) : '' ); + + if ( $e == "xls" ) { + $mime= "application/vnd.ms-excel"; + } + if ( $e == "ppt" ) { + $mime= "application/vnd.ms-powerpoint"; + } + } + //END CUSTOMIZATION + if ( isset( $this->mMimeTypeAliases[$mime] ) ) { $mime = $this->mMimeTypeAliases[$mime]; } V/r, Ryan Lane
