WordPress上传文件类型限制解决办法

文件类型不符合安全规则。试试别的文件。

这种错误是由于WordPress中做了文件上传格式的限制，这种限制可以在WordPress中的wp-include/functions.php的get_allowed_mime_types函数中找到，函数如下：

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，一劳永逸。
