Descrizione

strychni0x Media Bridge adds a “Cloud” tab to the WordPress media modal
(the “Add Media” dialog). From there an administrator can browse the folders of
one or more configured cloud accounts, preview the file names and import images
into the WordPress media library with a single click.

The plugin works with WebDAV-based clouds of the Nextcloud family:

Nextcloud
ownCloud

You can connect several accounts of mixed types at the same time and switch
between them with a dropdown in the media dialog.

Imported images become regular WordPress attachments (a copy is downloaded from
the cloud server), so they work with every theme, block and page builder without
any further integration.

Features

Adds a dedicated “Cloud” tab to the media modal.
Adds an “Import from cloud” button to the Media Library and the
“Add New Media File” screen, opening the browser in its own dialog.
Connect multiple Nextcloud / ownCloud accounts at once and pick
which one to browse from a dropdown.
Browse cloud folders via WebDAV.
Thumbnail previews with a per-account selectable source: use the server’s
native preview/thumbnail endpoint (default), or have WordPress generate and
cache the thumbnails itself (useful when the server has preview generation
disabled – and a reliable fallback for servers whose preview API differs).
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).
Per-account 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 “Cloud” 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 the Nextcloud or ownCloud servers 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) cloud
instances.

What is sent, and when:

When an administrator opens the “Cloud” tab or clicks the connection test,
the plugin sends a WebDAV PROPFIND request to the configured server URL
to list folder contents. The request includes the configured username and
app password as an HTTP Basic authentication header.
When the “Cloud” tab shows images, the plugin requests a thumbnail for each
image from the server’s native preview/thumbnail endpoint (Nextcloud:
/index.php/core/preview; ownCloud: the files thumbnail API – both
authenticated) and proxies it to the browser.
If that returns no preview, or if the account is set to “Generate in
WordPress”, 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 server URLs you configure. All requests
originate from your WordPress server, not from the visitor’s browser.

The data handling of each cloud instance is governed by its own operator. Please
refer to the documentation and privacy policy of your provider:

Nextcloud: https://nextcloud.com/ – Privacy: https://nextcloud.com/privacy/
ownCloud: https://owncloud.com/ – Privacy: https://owncloud.com/privacy-policy/

Installazione

Upload the strychni0x-media-bridge-for-nextcloud folder to /wp-content/plugins/.
Activate the plugin through the “Plugins” menu in WordPress.
In your cloud (Nextcloud/ownCloud) go to Settings Security
“Create new app password” and copy the generated password.
In WordPress go to Settings Cloud Media, choose the cloud type and enter the
server URL, the username, the app password and (optionally) a start folder.
Click “Check connection” to verify. Use “Add cloud” to connect more accounts.
Open the “Add Media” dialog in the editor or media library; a new “Cloud” tab
is now available (with a dropdown to pick the account when you have several).

FAQ

Which cloud servers are supported?

Nextcloud and ownCloud – WebDAV-based servers of the Nextcloud family that
support app passwords. You can connect several accounts of mixed types at the
same time and switch between them in the media dialog.

Are the images copied or referenced?

Copied. When you import an image it is downloaded from the cloud server and
stored as a regular WordPress attachment. There is no live link back to the
cloud after the import.

The thumbnails stay grey – what can I do?

Some servers do not generate image previews, and preview endpoints differ
between Nextcloud and ownCloud. In that case the default “from the
cloud server” mode has nothing to show. Go to Settings Cloud Media and switch
that account’s “Thumbnails” option to “Generate in WordPress”; WordPress will
then download each image once, build a cached thumbnail and display it. This
mode works with every supported server.

Who can use the Cloud tab?

Only administrators (users with the manage_options capability). You can change
the required capability with the ncmb_required_capability filter.

Is my cloud password safe?

Use an app password (Settings Security in your cloud), 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.

Changelog

2.0.0

Added support for ownCloud in addition to Nextcloud (both WebDAV based, using
an app password). Choose the cloud type per account.
You can now connect multiple cloud accounts at once and switch between them
from a dropdown in the media dialog.
Thumbnail source (“from the cloud server” vs. “generate in WordPress”) is now
a per-account setting; provider-specific native preview endpoints are used
(Nextcloud preview, ownCloud thumbnail API).
Settings screen redesigned as a repeatable list of accounts with a per-account
connection test.
Existing single-account (Nextcloud) configurations are migrated automatically –
no action required.

1.0.0

First public release.

0.9.0

Added “Select whole folder”: selects every image in the current folder across
all pages in one click, ready to import via “Import selection”.

0.8.0

Multi-select now persists across pages: ticked images stay selected when you
page through a folder, and “Import selection” imports them all. “Select page”
adds the current page; “Clear selection” clears everything.

0.7.0

Added an “Import from Nextcloud” button to the Media Library grid and the
“Add New Media File” screen. 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.
