From there an administrator can browse the folders of a configured Nextcloud account, preview the file names and import images into the WordPress media library with a single click. Imported images become regular WordPress attachments (a copy is downloaded from Nextcloud), so they work with every theme, block and page builder without any further integration. #### Features * Adds a dedicated “Nextcloud” tab to the media modal. * Adds an “Import from Nextcloud” button to the Media Library and the “Add New Media File” screen, opening the browser in its own dialog. * Browse Nextcloud folders via WebDAV. * Thumbnail previews with a selectable source: use the Nextcloud preview endpoint( default), or have WordPress generate and cache the thumbnails itself (useful when your Nextcloud server has preview generation disabled). * Paginated image listing for folders with many photos. * Import images as standard WordPress attachments – one at a time or several at once via multi-select. * Access restricted to administrators (the `manage_options` capability). * Connection test on the settings screen. #### Access control Every part of the plugin – the settings screen, the REST endpoints and the JavaScript that renders the Nextcloud tab – requires the `manage_options` capability. Non-administrators never receive the script and cannot call the REST endpoints. The required capability can be changed with the ncmb_required_capability filter. ### External services This plugin connects to a Nextcloud server that **you** configure on the plugin settings screen. It is not a third-party hosted service operated by the plugin author; you point it at your own (or your organisation’s) Nextcloud instance. What is sent, and when: * When an administrator opens the “Nextcloud” tab or clicks the connection test, the plugin sends a WebDAV `PROPFIND` request to the configured Nextcloud URL to list folder contents. The request includes the configured username and app password as an HTTP Basic authentication header. * When the “Nextcloud” tab shows images, the plugin requests a thumbnail for each image from the Nextcloud preview endpoint (`/index.php/core/preview`, authenticated) and proxies it to the browser. If that endpoint returns no preview, the plugin downloads the image via WebDAV once, generates a thumbnail on the WordPress server and caches it. * When an administrator imports an image, the plugin sends a WebDAV `GET` request( again authenticated) to download that single file. No data is sent anywhere other than the Nextcloud URL you configure. All requests originate from your WordPress server, not from the visitor’s browser. The data handling of that Nextcloud instance is governed by its own operator. Please refer to the documentation and privacy policy of your Nextcloud provider: * Nextcloud: https://nextcloud.com/ – Privacy: https://nextcloud.com/privacy/ ## Installation 1. Upload the `strychni0x-media-bridge-for-nextcloud` folder to `/wp-content/plugins/`. 2. Activate the plugin through the “Plugins” menu in WordPress. 3. In Nextcloud go to Settings Security “Create new app password” and copy the generated password. 4. In WordPress go to Settings Nextcloud Media and enter the Nextcloud URL, the username, the app password and (optionally) a start folder. Click “Check connection” to verify. 5. Open the “Add Media” dialog in the editor or media library; a new “Nextcloud” tab is now available. ## FAQ ### Are the images copied or referenced? Copied. When you import an image it is downloaded from Nextcloud and stored as a regular WordPress attachment. There is no live link back to Nextcloud after the import. ### The thumbnails stay grey – what can I do? Some Nextcloud servers do not generate image previews. In that case the default “ from Nextcloud” mode has nothing to show. Go to Settings Nextcloud Media and switch“ Thumbnails” to “generate in WordPress”; WordPress will then download each image once, build a cached thumbnail and display it. ### Who can use the Nextcloud tab? Only administrators (users with the `manage_options` capability). You can change the required capability with the `ncmb_required_capability` filter. ### Is my Nextcloud password safe? Use an app password (Settings Security in Nextcloud), never your real login password, so you can revoke it at any time. The credentials are used only on the server to authenticate WebDAV requests and are never exposed to the browser. The app password is stored encrypted in the database (libsodium, or OpenSSL with an HMAC as a fallback). The encryption key is derived from your WordPress salts by default. For stronger separation you may define your own key in wp-config.php: ``` define( 'NCMB_ENCRYPTION_KEY', 'a-long-random-string' ); ``` Note: if you change that constant (or your WordPress salts) later, the stored password can no longer be decrypted and must be re-entered on the settings screen. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “strychni0x Media Bridge for Nextcloud” is open source software.

It opens the Nextcloud browser in a standalone dialog, so you can import without going through a post or the block editor. #### 0.6.0 * Added multi-select: tick several images and import them all at once with a per- image progress indicator. Imports run sequentially to avoid timeouts on large photos. #### 0.5.3 * Plugin Check compliance: updated “Tested up to” and removed the unused “Domain Path” header. #### 0.5.2 * Fixed a fatal error (HTTP 500) when generating thumbnails in WordPress: the required wp-admin file was not loaded in the REST context. * Raised the memory limit before processing images and wrapped image handling in error handling, so importing/generating from large photos fails with a clear message instead of a blank 500 where possible. #### 0.5.1 * Added a setting to choose the thumbnail source: “from Nextcloud” (default, uses the preview endpoint) or “generate in WordPress”. The download/resize fallback now only runs when explicitly selected. #### 0.5.0 * Thumbnails now have a fallback: when the Nextcloud server provides no preview, the plugin downloads the image once, creates a thumbnail in WordPress and caches it (with an unguessable filename and a configurable size limit via the ncmb_max_thumb_bytes filter). The cache is removed on uninstall. #### 0.4.1 * Fixed: the Nextcloud tab is now registered as a top router tab (next to “Media Library”) instead of a left-hand menu item, so it shows up in every media modal– including the Featured Image dialog, which has no left menu. * Improved post-import behaviour so the imported image is selected in dialogs that have no dedicated insert state (e.g. Featured Image). #### 0.4.0 * Added pagination to the Nextcloud tab so folders with many images load in pages instead of all at once. The full folder listing is cached briefly on the server so paging does not trigger repeated requests to Nextcloud. #### 0.3.0 * The Nextcloud app password is now stored encrypted at rest (libsodium, with an OpenSSL+HMAC fallback). Existing plaintext passwords are read transparently and re-encrypted on the next save. Optional `NCMB_ENCRYPTION_KEY` constant for a dedicated key. #### 0.2.0 * Added thumbnail previews in the Nextcloud tab, proxied from the Nextcloud preview endpoint so credentials stay on the server. Graceful fallback when no preview is available. #### 0.1.0 * Initial release: Nextcloud tab in the media modal, folder browsing via WebDAV, image import into the media library, administrator-only access. ## Meta * Version **1.0.0** * Last updated **1 day ago** * Active installations **Fewer than 10** * WordPress version ** 6.0 or higher ** * Tested up to **7.0** * PHP version ** 7.4 or higher ** * Tags * [images](https://wordpress.org/plugins/tags/images/)[media](https://wordpress.org/plugins/tags/media/) [media library](https://wordpress.org/plugins/tags/media-library/)[Nextcloud](https://wordpress.org/plugins/tags/nextcloud/) [webdav](https://wordpress.org/plugins/tags/webdav/) * [Advanced View](https://wordpress.org/plugins/strychni0x-media-bridge-for-nextcloud/advanced/) ## Ratings No reviews have been submitted yet.
