Enable Drag and Drop on Adding Plugin Upload

A WordPress plugin that adds drag and drop capabilities to plug-in uploads across the admin: the plug-in installer (/wp-admin/plugin-install.php), the Plugins page (/wp-admin/plugins.php), and the install/update result pages (/wp-admin/update.php), so you can keep uploading plug-ins without leaving the page.

Features:

• Drag and drop ZIP files directly onto the upload form
• Drag and drop one or more plugin ZIPs directly onto the Plugins list (plugins.php) — no need to open the upload form first
• Upload multiple plug-in ZIP files at once – they are installed one at a time with a per-file status list
• Upload queue: added files append to the list, each on its own line with a remove button
• “Upload Plugin” button on the Plugins page, next to “Add Plugin”, that reveals the upload form
• Upload form shown again after each install or update, so you can upload another plug-in right away
• One-click “Activate Uploaded Plugins Now” button after installation completes
• In-place replacement of already-installed plug-ins via a “replace existing [current version] with new [uploaded version]” link
• Click-to-browse functionality on the drop zone
• Automatic file validation (ZIP files only)
• Visual feedback, success/error messages, and smooth animations

How It Works:

The plug-in: * Loads on the plug-in install page (plugin-install.php), the Plugins page (plugins.php), and the upload result pages (update.php) * Adds a visual drop zone in place of the standard upload form * On the Plugins list page, also accepts drops anywhere on the list (shows an overlay while dragging) * Handles drag and drop events and validates dropped files (must be ZIP files) * Queues the selected files and installs them one at a time using WordPress’s own upload handler * Shows a per-file result list with options to replace already-installed plug-ins and activate the new ones * Provides visual feedback during drag operations

Browser Support:

Works in all modern browsers that support the HTML5 Drag and Drop API: * Chrome * Firefox * Safari * Edge
