=== Easy Integration for Dropbox – File Manager === Contributors: ultradevs, mhimon Donate link: https://ultradevs.com/donate Tags: dropbox, file manager, cloud storage, file upload, gallery, embed, shortcode, form Requires at least: 6.2 Tested up to: 7.1 Stable tag: 2.2.10 Requires PHP: 7.4.0 License: GPLv2 or later License URI: https://www.gnu.org/licenses/gpl-2.0.html Turn Dropbox into a WordPress file manager — browse, embed, upload & share files with shortcodes, blocks & forms. == Description == **[Easy Integration for Dropbox – File Manager](https://ultradevs.com/easy-dropbox-integration/) connects your WordPress site directly to Dropbox**, so you can browse, embed, upload, and manage files without ever touching your server's storage. Your files stay in Dropbox — WordPress just displays and manages them. Whether you need a simple download link, a full image gallery, or a way for visitors to upload files straight into your Dropbox account, the shortcode builder, Gutenberg blocks, and page-builder widgets get you there in minutes — no code required. https://www.youtube.com/watch?v=hvbuVTy6-7s = 💡 Why Choose Easy Dropbox Integration? = - ✅ **Save server space** — Dropbox stores the files, not your WordPress host, so large media libraries never eat your hosting quota. - ✅ **No coding required** — a visual shortcode builder plus Gutenberg, Elementor, and Divi support handle the setup. - ✅ **Built-in previews** — PDFs, Office documents, images, and video open in a responsive popup, no download needed. - ✅ **Form-ready uploads** — connect Contact Form 7 (or WPForms, Ninja Forms, and more with PRO) so submissions upload straight to Dropbox. - ✅ **SEO-friendly embeds** — shortcodes render clean, crawlable markup instead of files hidden behind a Dropbox login wall. - ✅ **Scales with PRO** — add multiple Dropbox accounts, sync with the WordPress Media Library, and more when you need it. = 🚀 Key Features = - **File Browser** – Browse, search, and organize Dropbox files and folders from the WordPress admin. - **Shortcode Builder** – Visually create embeds for documents, image galleries, view links, and download links. - **File Uploader** – Drop an uploader into any page, post, or Contact Form 7 form; submissions save straight to Dropbox. - **File Previewer** – Responsive popup previews for PDFs, Office documents, images, and more, powered by lightGallery and the Microsoft Office viewer. - **Gutenberg, Elementor & Divi Support** – Native blocks and a module for the page builder you already use. = 👥 Perfect For = - **Agencies & freelancers** managing client files without server storage limits. - **Course creators & membership sites** delivering downloadable resources. - **Real estate & portfolio sites** embedding image galleries and documents. - **Businesses collecting files** from customers through Contact Form 7 (or WPForms/Ninja Forms with PRO). = ⚡ Getting Started in 3 Steps = 1. Install and activate the plugin, then connect your Dropbox account from **Dropbox → Connect Dropbox** using the guided OAuth flow. 2. Open **Dropbox → Shortcode Builder** and create an embed for a document, gallery, or download link. 3. Paste the generated shortcode into any page or post — or use the Gutenberg block, Elementor widget, or Divi module instead. = ✨ Free Features = **⚙️ Easy Setup** Connect your Dropbox account in a few clicks with the guided OAuth flow. **🗂️ File Browser** Browse, search, and manage Dropbox files and folders directly from the WordPress admin. **⏫ File Uploader** Let visitors upload files straight to Dropbox from a shortcode, Gutenberg block, or Elementor widget. **🔍 File Search** Add a lightweight search box so visitors can quickly find Dropbox files by name. **📝 Shortcode Builder** Visually create SEO-friendly embeds for folders, documents, galleries, and download links. **👁️ File Previewer** Show a responsive preview popup for PDFs, images, Office documents, and other files — no download required. **🔀 Contact Form 7 Integration** Add a Dropbox uploader to Contact Form 7 so submitted attachments save directly to Dropbox instead of your server. = 🚀 PRO Features = Unlock more with [Easy Dropbox Integration PRO](https://ultradevs.com/easy-dropbox-integration/): **🔒 User Private Files** Give logged-in users their own private Dropbox folder with per-user visibility controls for uploads and downloads. **📚 WordPress Media Library Integration** Sync Dropbox folders into the WordPress Media Library so you can reuse files in posts, blocks, and widgets like any other upload. **🔐 Multiple Dropbox Accounts** Connect and switch between several Dropbox accounts without re-authenticating — ideal for agencies managing multiple clients. **📁 Dropbox Team Folders** Use your Dropbox Business Team root as the plugin's root folder. Review existing shortcodes and linked folders first, since the root will no longer be your personal folder. **🎬 Media Player in Shortcode Builder** Play audio and video directly through shortcode embeds, no extra configuration needed. **📡 Media Streaming** Stream media assets from Dropbox with optimized buffering for smooth playback. **🎠 Slider Carousel Layouts** Display folder contents as a touch-friendly carousel to spotlight featured files. **💾 Storage Syncing** Keep Dropbox and WordPress media in sync automatically so files stay available wherever they're used. = 🔌 Integrations = **Included free:** - [Gutenberg Block Editor](https://wordpress.org/plugins/gutenberg/) – native blocks for embedding Dropbox content. - [Elementor Page Builder](https://wordpress.org/plugins/elementor/) – dedicated widgets for folders, galleries, and uploaders. - [Divi Page Builder](https://www.elegantthemes.com/gallery/divi/) – embed Dropbox shortcodes inside Divi. - [Contact Form 7](https://wordpress.org/plugins/contact-form-7/) – upload form attachments straight to Dropbox. **Available in PRO:** - [WooCommerce](https://wordpress.org/plugins/woocommerce/) – sell Dropbox files as downloadable products. - [WPForms](https://wordpress.org/plugins/wpforms-lite/) & [Ninja Forms](https://wordpress.org/plugins/ninja-forms/) – Dropbox file uploaders for form submissions. - Gravity Forms, Fluent Forms, Formidable Forms & MetForm – Dropbox uploaders for each form builder. - [Tutor LMS](https://wordpress.org/plugins/tutor/) – use Dropbox files as lesson or course intro videos. = 🗺️ Roadmap = We're actively expanding support to more page builders, form plugins, and LMS platforms — [let us know](https://ultradevs.com/easy-dropbox-integration/) what you'd like to see next. = 📚 External Libraries & Third-Party Services = This plugin relies on the following third-party libraries and services: - [Dropbox PHP SDK](https://github.com/kunalvarma05/dropbox-php-sdk) — communicates with the Dropbox API to browse, upload, and manage files. - [lightGallery](https://www.lightgalleryjs.com/) — renders responsive image, video, and document galleries and previews. - [Flaticon](https://www.flaticon.com/) — provides interface icons. - Google Docs Viewer (`docs.google.com/viewerng/viewer`) — embeds PDF previews. - Microsoft Office Viewer (`view.officeapps.live.com`) — embeds Office document previews. = 🔐 Data Privacy = Connecting Dropbox requires your own Dropbox App (see the FAQ below) — the plugin does not use a shared or default Dropbox App. When you complete the OAuth flow from **Dropbox → Connect Dropbox**, your site talks directly to Dropbox's own authorization servers, and Dropbox redirects back to your site once you approve access. **No ultraDevs server is involved in this exchange, and your files are never stored on or transferred through our infrastructure.** All file operations happen directly and securely between your server and Dropbox's API. See the [ultraDevs Privacy Policy](https://ultradevs.com/privacy-policy/) for how we handle other data, such as license and support information. = 💬 Support, Docs & Community = - 🆘 [Free Support Forum](https://wordpress.org/support/plugin/easy-dropbox-integration/) - 📖 [Documentation](https://ultradevs.com/docs/easy-dropbox-integration) - 🎥 [Video Tutorials](https://www.youtube.com/playlist?list=PL6-MOhUm73eiSSVHgAVnFFEvs6rO2sZyC) - 💬 [Live Chat on Facebook](https://web.facebook.com/hello.ultradevs) - 👥 [Facebook Community Group](https://web.facebook.com/groups/ultradevs/) - 📺 [YouTube Channel](https://www.youtube.com/channel/UCc2yL-QGQjscXpPx9Pp7J8w) - 🐦 [Twitter/X](https://twitter.com/ultraDevsBD) - 📸 [Instagram](https://www.instagram.com/ultradevs/) Made with ❤️ by [ultraDevs](https://ultradevs.com). == Installation == 1. Upload the plugin files to `/wp-content/plugins/easy-dropbox-integration`, or install it directly through **Plugins → Add New** in your WordPress admin. 2. Activate the plugin through the **Plugins** screen. 3. Go to **Dropbox → Connect Dropbox** and follow the guided OAuth flow to link your Dropbox account. 4. Open **Dropbox → Shortcode Builder** to create your first embed, then paste the shortcode into any page or post. == Frequently Asked Questions == = Is it safe to connect my Dropbox account with this plugin? = Yes. The plugin uses the official Dropbox API, and after the OAuth handshake, file transfers happen directly and securely between your server and Dropbox — no ultraDevs server is involved. See Data Privacy above for details. = Does the plugin require a Dropbox App of my own? = Yes, you need to create a Dropbox App and get the App Key and App Secret from the Dropbox Developer Console. Follow the [step-by-step guide](https://ultradevs.com/docs/easy-dropbox-integration/settings/how-to-link-your-own-dropbox-app-with-easy-dropbox-integration-plugin/) to set one up — it only takes a few minutes. = Can I embed Dropbox folders on any WordPress page? = Yes, the shortcode builder, Gutenberg blocks, and Elementor and Divi support let you place Dropbox folders, files, or galleries anywhere your theme allows content. = Can I use Dropbox files in WooCommerce? = Yes, with the WooCommerce Downloadable Products integration in the PRO version, you can deliver downloadable products straight from Dropbox. = Do my visitors need their own Dropbox account? = No. Visitors browse, preview, and download files through your WordPress site — they never need to log in to Dropbox or see your account. = What happens to my files if I deactivate the plugin? = Your files always stay safely in Dropbox. Deactivating the plugin only removes the WordPress-side embeds and local cache; nothing is deleted from your Dropbox account. = Will this slow down my website? = No. Files are served from Dropbox instead of your own server, and file listings are cached locally so repeat visits load quickly without hitting the Dropbox API every time. == Screenshots == 1. File Browser 2. Shortcode Builder 3. Settings == Changelog == = 2.2.10 - 14 September, 2026 = - **Fix:** Frontend gallery images could still show as permanently broken until a full page reload — large originals over Dropbox's thumbnail size limit are now resized and cached locally instead of being served as a raw, repeatedly-refetched original file. - **Enhancement:** Gallery images now retry automatically if a load briefly fails, instead of requiring a manual page reload. - **New:** Added Move, Duplicate, and Share to the File Browser's file/folder menu (previously showed "Coming Soon"). - **New:** Added Cut & Paste to the File Browser — cut a file or folder from its menu, then use the new Paste button to move it into any folder you open. - **Fix:** Dropbox errors (such as a naming conflict when moving, duplicating, or renaming a file) showed a raw error code instead of a clear, readable message. - **Fix:** The File Browser's ⋮ and right-click menus could appear as an empty box (just their divider lines) on a shortcode with every file or folder action disabled — the menu, and its ⋮ button, no longer render when there's nothing left to show. - **New:** **PRO Feature:** Tutor LMS Integration module now lets you select Dropbox files as lesson or course intro videos in the Tutor LMS course builder. = 2.2.9 - 11 September, 2026 = - **Fix:** Frontend gallery images could show as broken (with working click/preview links) until the page was reloaded — cached thumbnail URLs that had gone stale (expired Dropbox temporary links or cleared local thumbnail files) are now detected and regenerated automatically. - **New:** Added a search box to the File Browser so you can quickly find files and folders by name. - **Fix:** Dropdown css classnaming conflict. - **Fix:** The File Browser could show stale results after uploading a file or clicking Refresh — every other refresh silently reused cached data instead of pulling new files. Uploads and manual refreshes now always fetch the latest data from Dropbox. - **Fix:** Many file types (.txt, .csv, .docx, code files, fonts, archives, and more) showed a folder icon in the File Browser instead of their correct file-type icon. = 2.2.8 - 30 August, 2026 = - **Fix:** Saving or duplicating a shortcode could fail with a database error ("Unknown column 'hash'") on sites where the 2.2.0 schema migration was silently missed — the migration now re-runs and repairs the table automatically. - **Fix:** Reactivating the plugin after an update no longer skips pending database migrations. - **New:** "Check & Repair Database" tool in Settings → Tools re-checks the plugin tables and restores missing columns/indexes on demand. - **Enhancement:** Database update routines now record failures and show an admin notice with a retry action instead of failing silently. = 2.2.7 - 26 August, 2026 = - **Fix:** Fatal error ("Call to a member function getToken() on null") when connecting an account whose Dropbox app is missing required permissions, or when a request ran without a valid access token — the plugin now fails gracefully and asks you to reconnect. - **Fix:** Connection errors now show a clear, actionable message (incorrect App Key or Secret, Redirect URI not registered, server unable to reach Dropbox, expired authorization code) instead of failing silently. - **Enhancement:** The app setup screen now lists all six permission scopes your Dropbox app must enable before connecting. - **Fix:** PRO badges and upgrade prompts were shown to users with an active PRO license. - **Fix:** Connecting again while an earlier authorization window is still open no longer fails with "CSRF Token Mismatch" — outstanding authorization links stay valid until used. - **Fix:** Compatibility with page-cache plugins such as LiteSpeed Cache — cached AJAX responses could leave the settings page loading forever; all plugin AJAX responses are now sent with no-cache headers. = 2.2.6 - 21 August, 2026 = - **Improvement:** "Clear Attachments" (Media Library settings) now asks for confirmation before removing the Dropbox attachments. = 2.2.5 - 19 August, 2026 = - **QUICK FIX:** Fixed a bug that caused clear cache to not work properly in some cases. = 2.2.4 - 19 August, 2026 = - **Fix:** Files could swap thumbnails or disappear when the same Dropbox account was connected twice — cached files are now stored per account. - **Fix:** "Clear Cache" now removes the cached files of every connected account, plus the stored thumbnails and stale thumbnail links. - **Fix:** Renaming a file in the file browser no longer leaves its cached copy pointing at the old location. = 2.2.3 - 15 August, 2026 = - **Fix:** Fixed folders not found while switching accounts in some cases. - **Improvement:** Improved shortcode and added folder selection for image gallery and other shortcodes. = 2.2.2 - 09 August, 2026 = - **Fix:** Fixed Media Library Integration issue in some cases. - **New:** Added Ninja Forms Integration module for file uploads (PRO). = 2.2.1 - 03 August, 2026 = - **Enhancement:** Added preset design templates for Image Gallery shortcodes and some new shortcode builder options for better customization. = 2.2.0 - 24 July, 2026 = - **Security:** Closed a front-end IDOR. The numeric shortcode `id` is no longer exposed to anonymous visitors — `[easy_dropbox_integration id="N"]` is resolved on the server and only an unguessable stored hash is emitted as the front-end `shortcode_id` used to authorize file-listing requests. The short `[id="N"]` shortcode, admin edit URLs, and admin CRUD AJAX continue to use the numeric id (admin-only). - **Security:** Fixed a path-traversal flaw in the per-shortcode folder-allowlist check. Paths are now canonicalized (`.`/`..` collapsed) before comparison, so requests like `/allowed/../../outside` can no longer reach folders outside the configured source. - **Security:** Front-end shortcode views are now scoped to the shortcode's allowed folders for all users, including administrators. A request carrying a `shortcode_id` can no longer list folders outside the configured source by changing the `path` — the admin bypass now applies only to the unscoped admin file manager. - **Security:** Hardened write operations — `rename` now validates the destination path too, and `create_folder` validates the full joined path, preventing escape from the allowed folder for management-capable users. - **Security:** `sync_storage` no longer returns connected-account details (emails, scopes, the full account list) to non-administrators; front-end callers receive only public fields. - **Security:** Hardened AJAX authorization for the frontend file browser and uploader. File actions now require either an administrator capability or a valid shortcode context; they are no longer reachable by unauthenticated users without a shortcode. - **Security:** Enforced the per-shortcode source-folder allowlist for every file action (list, download, preview, direct link, media, stream, zip, upload), and denied access by default when no shortcode context is present. - **Security:** Stopped exposing connected-account details (Dropbox owner email, administrator email, OAuth scopes) to anonymous visitors in front-end localized data. - **Fix:** Fixed image preview for some file types. - **Fix:** Fixed shortcode builder for some cases. - **Fix:** Account ID is now correctly passed to the front-end for shortcodes with multiple accounts. - **Update:** Updated Freemius SDK to 2.13.4 = 2.1.0 - 20 July, 2026 = - **Fix:** Account Storage UI Issue. - **Improvement:** Dropbox App Permissions Handling. - **Fix:** Shortcode Preview Nonce Issue. - **New:** Added App Folder Support. = 2.0.4 - 16 May, 2026 = - **Fix:** Form Uploader for non-authenticated users. = 2.0.3 - 31 March, 2026 = - **Fix:** App Setup Page Assets Loading. - **Improvement:** Freemius Integration. - **Improvement:** Code Quality. - **Fix:** Plugin Name Change. = 2.0.2 - 20 March, 2026 = - **New:** Added get_files ajax functionality. - **Improvement:** Refactored Freemius integration via Composer. - **Improvement:** Settings sanitization enhancements. - **Improvement:** Better debugging capabilities. - **Fix:** Database prepare statement fixes. - **Fix:** File browser and refresh issues resolved. - **Fix:** PHPCS and general code formatting improvements. = 2.0.1 - 27 February, 2026 = - **Fix:** Ajax Error. = 2.0.0 - 20 February, 2026 = - **Fix:** Some Issues. - **Fix:** Media Library Folder Selection. - **Improvement:** Refresh Token. - **Improvement:** Active Account Management. - **Improvement:** File Uploader Shortcode. - **Fix:** Connect Dropbox Error. - **Fix:** Set access token issue. - **Improvement:** CSS. = 1.14.0 - 27 January, 2026 = - **Fix:** Multiple account shortcode view issue. - **Improvement:** Filebrowser. - **New:** Module Preview. - **Fix:** Refresh Token Issue. = 1.13.2 - 17 January, 2026 = - **Fix:** Refresh Token Issue. - **New:** File Browser Component Exported to Window for External Usage. - **Fix:** Rename issue. - **Improvement:** REST API. - **Improvement:** Error Handling. = 1.13.1 - 08 January, 2026 = - **Fix:** Replace cache `.htaccess` files. = 1.13.0 - 08 January, 2026 = - **Fix:** Shortcode Builder Issue. - **New:** Media Player Support in Shortcode builder. - **New:** Media Streaming. - **New:** Slider Carousel in Shortcode Builder. - **New:** Storage Syncing. = 1.12.6 - 3 January, 2026 = - **Improvement:** Thumbnail folder security. = 1.12.5 - 3 January, 2026 = - **Fix:** Module Manager. = 1.12.4 - 3 January, 2026 = - **Improvement:** Frontend CSS. - **Improvement:** Assets Class. - **New:** Added Delete Button for Uploaded Files List. - **Enhancement:** Uploader Component. - **New:** Added WPForms Support. - **New:** Added Import to Media Library Feature. = 1.12.3 - 20 December, 2025 = - **New:** Shared Link Cache Added. - **New:** Direct Download Link Added. - **Fix:** Media Library Folder Selection Issue. - **Improvement:** Thumbnail Security Improvement. - **Improvement:** Uploader UI Improvement. - **Fix:** Elementor Form Uploader Module. = 1.12.2 - 12 October, 2025 = - **Fix:** Load Text Domain warning issue. - **Fix:** Some Issues. - **Improvement:** Code Improvement. - **Improvement:** Assets loading improvement. = 1.12.1 - 24 September, 2025 = - **Fix:** Some CSS Issues. = 1.12.0 - 23 September, 2025 = - **Enhancement:** New File Browser, Shortcode Builder, Settings UI. - **New:** Download folder as Zip. - **New:** File/Folder More Menu in File Browser. - **Fix:** Some Issues. - **Update:** Performance Improvements. = 1.11.1 - 30 April, 2025 = - **Update:** No more default Dropbox App Key and Secret. = 1.11.0 - 12 January, 2025 = - **New:** CF7 Module Opener Button Styles. - **New:** Elementor Pro Form Uploader Module. = 1.10.0 - 21 December, 2024 = - **Fix:** Header Already Sent Issue. - **Fix:** Elementor Module. - **Fix:** Account Removal Issue. - **New:** Added Option to use Own Dropbox App. - **New:** Added CF7 compatibility. = 1.9.1 - 1 December, 2024 = - **Fix:** PHP Version Issue. - **Fix:** Elementor Module. - **Update:** Dropbox App Key and Secret. = 1.9.0 - 30 October, 2024 = - **New:** File Uploader Elementor Widget. - **Fix:** Admin Common CSS loading. = 1.8.0 - 27 October, 2024 = - **Fix:** Media Library. - **New:** Gutenberg Shortcode Modules Block. - **Fix:** UI Changes, Admin Common CSS compatibility. - **Fix:** Ajax Class Active Account Issue. = 1.7.0 - 10 October, 2024 = - **Fix:** Shortcode Permission. - **Fix:** Folder Selector Modal Fix. - **New:** More Uploader Config Options. - **New:** WordPress Media Library Integration.
