Rocket Media Library Mime Type

A small plugin that collects useful upload-related features. It has four main features.

1. Choose the file types that may be uploaded to the media library. For example, use it when hwp (Hangul Word Processor) files are rejected by WordPress.
2. Filter the media library list by file extension. Example: show only hwp files.
3. Automatically convert Korean file names to Latin letters (romanization) on upload. Example: 사과.jpg becomes sagwa.jpg, and 한글 파일.jpg becomes hangeul-pail.jpg. A separate option appends the upload date and time to the file name (for example photo__2026-01-31-09-30-00.jpg).
4. Restrict risky file types (svg, exe, macro-enabled Office files) to administrators.

한국어 안내 워드프레스 업로드와 관련된 기능을 모은 플러그인입니다. 설정은 설정 > 업로드 파일 타입에서 합니다.

• 업로드를 허용할 파일 타입 선택 (hwp, svg, csv 등)
• 한글 파일명을 로마자로 자동 변환 (예: 사과.jpg > sagwa.jpg). 외부 서비스나 API 키가 필요 없습니다.
• 파일명 뒤에 업로드 일시 붙이기, 맥(macOS)에서 올린 한글 파일명 고치기
• 위험한 형식(svg, exe, 매크로 파일)은 관리자만 업로드

Korean file name conversion Korean letters are converted to Latin letters using the letter table of the Revised Romanization of Korean. This is not a translation: 사과 becomes sagwa, not Apple. The conversion is calculated on your server, no external service is used, and no API key or fee is needed. Pronunciation-dependent rules (such as liaison) are not applied; each letter is converted as it is. Example: 신라 becomes sinra. Files uploaded from macOS often have Korean letters split into consonants and vowels (Unicode NFD), which look broken on servers and Windows. With the option "Fix Korean file names uploaded from macOS" turned on, the letters are combined back into normal Korean when the file is uploaded. Selectable file extensions hwp, bmp, doc, ico, xla/xls/xlt/xlw, xlsx, pot/pps/ppt, pptx, ppam, pptm, psd, mp4, webm, ogv, csv, ai/eps/ps, txt, svg, json, exe, and the file types WordPress allows by default (jpg, png, gif, mp3, mov, avi, wmv, mid, pdf, zip, gz). Security notice: Allow svg, exe and files that may contain macros (ppam, pptm) with care. After uploading the file you need, turn the option off again. With the option "Only administrators can upload risky file types" (on by default), users who are not administrators cannot upload these types even if they are enabled.

The installation is the same as for any WordPress plugin.

1. Upload the plugin folder (rocket-media-library-mime-type) to /wp-content/plugins/, or install it from the plugin search in the admin screen.
2. Activate the plugin.
3. Go to Settings > Upload File Types, choose the file types you want to allow, and save.

3.0.2

• security : Re-confirmed that saving the settings is protected against Cross-Site Request Forgery (CSRF): it requires a logged-in user with the manage_options capability and a valid nonce.
• fix : Fixed the position of the Yes / No labels on the switches of the settings screen.
• change : The readme now lists the WordPress.org user name qwerty-23 as contributor.

3.0.1

• fix : File type settings were reset when the plugin was deactivated and activated again.
• fix : Types that WordPress allows by default (doc, xlsx, pptx, csv, bmp, ico, mp4, txt and others) are on by default on a fresh install.
• fix : File name conversion applies only to uploads, and no longer leaves %xx in URLs for letters that cannot be romanized.
• fix : The plugin no longer allows a file type that another plugin or form has deliberately excluded for a specific upload.
• fix : Removed the use of seems_utf8(), which is deprecated since WordPress 6.9.
• change : The readme is now written in English (with a short Korean summary), as required by WordPress.org.
• change : uninstall.php no longer creates global variables.

3.0.0

• security : Fixed an issue that allowed users who were not logged in to change the settings. Saving settings now checks capability and nonce. Please update.
• security : All output of the settings screen is escaped, and each saved value is validated.
• fix : File type settings were reset when the plugin was deactivated and activated again.
• fix : File types that WordPress allows by default (doc, xlsx, pptx, csv, bmp, ico, mp4, txt and others) were blocked on a fresh install. The defaults now match WordPress.
• fix : File name conversion is applied only when a file is uploaded (other file name handling is not affected). Also fixed broken file URLs caused by letters that cannot be romanized.
• security : Added warnings for svg, exe and macro-enabled files, and an option (on by default) to let only administrators upload risky file types.
• change : "Append upload date and time" is now a separate option that applies to all files, regardless of Korean conversion (off by default). When updating, it is turned off for sites that did not use the Korean conversion, so existing file names do not suddenly change.
• new : Added an option that combines Korean file names split into consonants and vowels (uploaded from macOS) into normal Korean.
• change : A save bar is fixed at the bottom of the screen and warns about unsaved changes.
• fix : Switches that were turned off were not saved as off.
• fix : Settings were not applied to files uploaded from the block editor (REST API).
• fix : Removed code that changed the PHP time zone of the site. The upload date and time use the site time zone.
• fix : Wrong default for xlsx.
• change : The settings screen keeps the same look as before. Libraries previously loaded from external CDNs (Foundation, Font Awesome and others) are now bundled with the plugin, so the settings screen loads nothing from external sites.
• change : Korean file name conversion now uses romanization, and the Naver Papago translation option was removed. The free Papago API ended in February 2024. Romanization needs no external service, API key or fee. Example: 사과.jpg to sagwa.jpg. Previously saved API keys are deleted automatically on update.
• change : Korean detection is limited to Hangul syllables and jamo (Hanja and others were treated as Korean before).
• change : Requires PHP 7.0 or later and WordPress 5.0 or later.
• add : Settings are cleaned up when the plugin is deleted.
