 WordPress禁止上传特定类型文件的方法 WordPress支持上传的文件类型非常广泛，具体包括哪些格式的文件类型，我们可以在主题的 functions.php 文件中插入以下php代码：print_r(wp_get_mime_types());然后打开网站首页，查看网页源代码，即可看到一个完整的支持列表（看完后，记得删除）：// []中括号中的名称代表文件名后缀名/扩展名 // =& 后面的名称代表的是后缀名所在应的文件MIME信息 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 [mp4|m4v] =& video/mp4 [ogv] =& video/ogg [mkv] =& video/x-matroska [txt|asc|c|cc|h] =& text/plain [csv] =& text/csv [tsv] =& text/tab-separated-values [ics] =& text/calendar [rtx] =& text/richtext [css] =& text/css [htm|html] =& text/html [mp3|m4a|m4b] =& audio/mpeg [ra|ram] =& audio/x-realaudio [wav] =& audio/wav [ogg|oga] =& audio/ogg [mid|midi] =& audio/midi [wma] =& audio/wma [mka] =& audio/x-matroska [rtf] =& application/rtf [js] =& application/javascript [pdf] =& application/pdf [swf] =& application/x-shockwave-flash [class] =& application/java [tar] =& application/x-tar [zip] =& application/zip [gz|gzip] =& application/x-gzip [rar] =& application/rar [7z] =& application/x-7z-compressed [exe] =& application/x-msdownload [doc] =& application/msword [pot|pps|ppt] =& application/vnd.ms-powerpoint [wri] =& application/vnd.ms-write [xla|xls|xlt|xlw] =& application/vnd.ms-excel [mdb] =& application/vnd.ms-access [mpp] =& application/vnd.ms-project [docx] =& application/vnd.openxmlformats-officedocument.wordprocessingml.document [docm] =& application/vnd.ms-word.document.macroEnabled.12 [dotx] =& application/vnd.openxmlformats-officedocument.wordprocessingml.template [dotm] =& application/vnd.ms-word.template.macroEnabled.12 [xlsx] =& application/vnd.openxmlformats-officedocument.spreadsheetml.sheet [xlsm] =& application/vnd.ms-excel.sheet.macroEnabled.12 [xlsb] =& application/vnd.ms-excel.sheet.binary.macroEnabled.12 [xltx] =& application/vnd.openxmlformats-officedocument.spreadsheetml.template [xltm] =& application/vnd.ms-excel.template.macroEnabled.12 [xlam] =& application/vnd.ms-excel.addin.macroEnabled.12 [pptx] =& application/vnd.openxmlformats-officedocument.presentationml.presentation [pptm] =& application/vnd.ms-powerpoint.presentation.macroEnabled.12 [ppsx] =& application/vnd.openxmlformats-officedocument.presentationml.slideshow [ppsm] =& application/vnd.ms-powerpoint.slideshow.macroEnabled.12 [potx] =& application/vnd.openxmlformats-officedocument.presentationml.template [potm] =& application/vnd.ms-powerpoint.template.macroEnabled.12 [ppam] =& application/vnd.ms-powerpoint.addin.macroEnabled.12 [sldx] =& application/vnd.openxmlformats-officedocument.presentationml.slide [sldm] =& application/vnd.ms-powerpoint.slide.macroEnabled.12 [onetoc|onetoc2|onetmp|onepkg] =& application/onenote [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 [wp|wpd] =& application/wordperfect )上面的源代码中，在每一行的左边中括号中的名称是文件的后缀名（或者叫扩展名），右边 =& 后面的名称代表的是后缀名所对应的文件MIME信息。如果想禁止用户在WordPress后台发表文章时上传特定后缀名的文件，我们可以在主题的 functions.php 文件中添加以下php代码：add_filter(‘upload_mimes’, ‘custom_upload_mimes’);function custom_upload_mimes( $existing_mimes=array() ) { // 注意中括号中的名称，必须取自上面支持列表中中括号内的名称 unset( $existing_mimes[‘exe’] ); //此处禁止了上传exe后缀名的文件return $existing_ }如果想禁止上传多种后缀名的文件，可以添加以下php代码：add_filter(‘upload_mimes’, ‘custom_upload_mimes’); function custom_upload_mimes( $existing_mimes=array() ) { // 注意中括号中的名称，必须取自上面支持列表中中括号的名称 unset( $existing_mimes[‘exe’] ); //此处禁止了上传exe后缀名的可运行文件 unset( $existing_mimes[‘jpg|jpeg|jpe’] ); //此处禁止了上传jpg、jpeg和jpe后缀名的压缩文件 unset( $existing_mimes[‘gif’] ); //此处禁止了上传gif后缀名的图片文件 unset( $existing_mimes[‘png’] ); //此处禁止了上传png后缀名的图片文件 return $existing_ }经过此项设置，用户如果在后台上传禁止的文件类型，那么会得到这样的提示：文章来源： 本文链接： 版权所有：非特殊声明均为本站原创文章，转载请注明出处：在线留言博主最新文章
