我们在使用wordpress网站的时候,上传附件经常会出现错误,显示无法上传这个类型文件。
如果需要拓展支持的附件类型可以通过下面的方法,增加文件类型。
限制类型可以在WordPress中的wp-include/functions.php的get_allowed_mime_types函数中找到
function get_allowed_mime_types() { static $mimes = false; if ( !$mimes ) { // Accepted MIME types are set here as PCRE unless provided. $mimes = apply_filters( 'upload_mimes', array( 'jpg|jpeg|jpe' => 'image/jpeg', 'gif' => 'image/gif', 'png' => 'image/png', 'bmp' => 'image/bmp', 'tif|tiff' => 'image/tiff', 'ico' => 'image/x-icon', 'asf|asx|wax|wmv|wmx' => 'video/asf', 'avi' => 'video/avi', 'divx' => 'video/divx', 'flv' => 'video/x-flv', 'mov|qt' => 'video/quicktime', 'mpeg|mpg|mpe' => 'video/mpeg', 'txt|c|cc|h' => 'text/plain', 'rtx' => 'text/richtext', 'css' => 'text/css', 'htm|html' => 'text/html', 'mp3|m4a' => 'audio/mpeg', 'mp4|m4v' => 'video/mp4′, 'ra|ram' => 'audio/x-realaudio', 'wav' => 'audio/wav', 'ogg' => 'audio/ogg', 'mid|midi' => 'audio/midi', 'wma' => 'audio/wma', 'rtf' => 'application/rtf', 'js' => 'application/javascript', 'pdf' => 'application/pdf', 'doc|docx' => 'application/msword', 'pot|pps|ppt|pptx' => 'application/vnd.ms-powerpoint', 'wri' => 'application/vnd.ms-write', 'xla|xls|xlsx|xlt|xlw' => 'application/vnd.ms-excel', 'mdb' => 'application/vnd.ms-access', 'mpp' => 'application/vnd.ms-project', 'swf' => 'application/x-shockwave-flash', 'class' => 'application/java', 'tar' => 'application/x-tar', 'zip' => 'application/zip', 'gz|gzip' => 'application/x-gzip', 'exe' => 'application/x-msdownload', // openoffice formats 'odt' => 'application/vnd.oasis.opendocument.text', 'odp' => 'application/vnd.oasis.opendocument.presentation', 'ods' => 'application/vnd.oasis.opendocument.spreadsheet', 'odg' => 'application/vnd.oasis.opendocument.graphics', 'odc' => 'application/vnd.oasis.opendocument.chart', 'odb' => 'application/vnd.oasis.opendocument.database', 'odf' => 'application/vnd.oasis.opendocument.formula', ) ); } return $mimes; }
以上传入 apply_filters函数中的Array,即使允许上传的类型列表,我们可以修改这个地方,以禁止或允许可以上传的文件类型。
例如我们想要允许rar文件上传,只需添加一行格式说明即可:
'rar' => 'application/rar',
除了直接修改这个Array外,还有另外一种方法,可以修改wp-config.php文件,这个文件在WordPress的根目录下,在其中增加一行语句:
define('ALLOW_UNFILTERED_UPLOADS', true);
这条语句将去除上传的文件类型限制,就可以支持任意格式了。
