描述

Flex Explorer adds a simple, read-only file browser to the WordPress admin. It
lets administrators look through the contents of the wp-content directory and
preview text files and images without leaving wp-admin or opening an FTP client.

It never modifies your site: it cannot create, edit, upload, rename, move or
delete files. You can download an individual file, or a whole folder as a ZIP,
for offline viewing, and the originals are always left untouched. Every request is
restricted to the wp-content directory, is limited to administrators, and is
verified with a nonce.

Features

Browse folders inside wp-content with a breadcrumb path.
List files and folders with size and last-modified date.
Search filenames in the current folder and everything below it.
Preview text and code files inline (up to 2 MB).
Preview common images (JPEG, PNG, GIF, WebP, BMP, ICO) inline (up to 5 MB).
Download any single file, or the current folder packaged as a ZIP.
Uses the jQuery bundled with WordPress and plain CSS – no build step, no external libraries.

Security

Access is limited to users with the manage_options capability.
On multisite, access is further restricted to network super admins, since a
per-site administrator should not be able to read the shared wp-content
tree.
If the site defines DISALLOW_FILE_EDIT as true, Flex Explorer disables
itself (including its admin menu) to respect that lockdown.
All AJAX requests are nonce-verified.
Every path is resolved with realpath() and confined to the wp-content
directory; path traversal and symlink escapes are rejected.
wp-config.php, .htaccess and .htpasswd can never be viewed or
downloaded, and are skipped when building a ZIP.
Downloads are always sent as attachments (application/octet-stream) so the
browser never renders file contents inline.
ZIP archives are bounded (file count and total size) and skip symlinks so a
large or looping tree cannot exhaust server resources.

安装

Upload the plugin files to /wp-content/plugins/flex-explorer, or install
through the WordPress Plugins screen.
Activate the plugin through the Plugins screen.
Open Tools Flex Explorer from the admin menu.

常见问题

Who can use Flex Explorer?: Users with the manage_options capability (administrators). On a multisite
network, access is limited to super admins, because manage_options is granted
to every per-site administrator while wp-content is shared across the network.
Why is Flex Explorer missing from my admin menu?: If your site (or your host) defines the DISALLOW_FILE_EDIT constant as true,
Flex Explorer disables itself entirely to honour that file-access lockdown. The
same applies to per-site administrators on multisite, who are not super admins.
Can it edit or delete files?: No. It never changes anything on disk: it cannot edit, rename, move, upload or
delete files. It can browse, search, preview, and download copies (including a
folder as a ZIP), but the originals are always left untouched.
How does search work?: Type in the search box to match filenames in the folder you are currently
viewing and all of its subfolders. Matching is a case-insensitive match on the
file name; results are capped, so narrow your search if you hit the limit.
Can I download a whole folder?: Yes. Use Download folder as ZIP to package the current folder (and its
subfolders) into a single archive. Very large folders are refused to protect
the server, and wp-config.php, .htaccess and .htpasswd are never
included. ZIP support requires the PHP zip extension.
Which folders can I browse?: Only the wp-content directory and its subfolders. Paths outside it, and
symbolic links that point outside it, are rejected.
Why can’t I open wp-config.php?: Sensitive files (wp-config.php, .htaccess, .htpasswd) are blocked from
viewing by design.

更新日志

0.2.4

Derive the content root solely from wp_upload_dir() and drop the WP_CONTENT_DIR fallback, so the browser root is resolved entirely through core location functions with no internal constants.

0.2.3

Resolve the content directory through wp_upload_dir() instead of the WP_CONTENT_DIR constant, so the browser root follows custom content/uploads locations.
Restore the original zlib.output_compression setting after a download streams, keeping the change confined to the single download request.

0.2.2

New: search filenames in the current folder and all subfolders (results are bounded); matching folds multibyte characters where available.

0.2.1

Lowered the ZIP size limit to 50 MB so archives stay within typical shared-hosting execution limits.

0.2.0

New: download an individual file (sent as an attachment, never rendered inline).
New: download the current folder as a ZIP, with file-count and total-size limits, skipping symlinks and blocked files.
Downloads flush pending output buffers and disable on-the-fly compression before streaming, so binary files and archives are never corrupted or truncated.

0.1.1

Security: on multisite, restrict access to network super admins instead of every per-site administrator.
Security: disable the plugin (including its admin menu) when DISALLOW_FILE_EDIT is defined as true.
Move the admin page under Tools instead of a top-level menu item.

0.1.0

Initial release: read-only browsing of wp-content with inline text and image preview.
