KDA Media Button

KDA Media Button extends the classic WordPress editor with a new button. Clicking the button opens a popup window that gives access to the site structure so you can:

• Browse folders relative to a configured base folder.
• Upload new images directly into the current folder.
• Select an existing image and insert it into the post.

The plugin is fully configurable from its settings page:

• Accessible folder — a path relative to the site root. The plugin can only browse and upload inside this folder, which keeps the rest of the filesystem protected.
• Allowed formats — comma separated list of allowed extensions. Leaving it empty allows all common image formats (jpg, jpeg, png, gif, webp, svg, ico, bmp, tiff, tif, avif).
• Roles — choose which roles (e.g. Administrator, Editor) can see the editor button.
• Lightbox link class — set a custom CSS class for the image link, or leave empty to disable the class.
  • Activity log — optionally keep a log of uploads, deletions, folder creation and renames.
  • Prefix with record ID — optionally prepend the current post ID to uploaded filenames. If a file with the same name already exists, a numeric suffix is added automatically.

Gutenberg support

Gutenberg block support is available in beta mode. The plugin is primarily designed for the classic editor. You can enable the experimental Gutenberg block from the settings page if you want to test it.

Working with images

When an image is selected you can fine-tune the insertion:

• Size — insert the original (Full) or a generated Thumbnail / Medium / Large copy.
• Alignment — None, Left, Center or Right (adds the matching WordPress align class).
• Alt text — custom alternative text for the inserted image.
• Link to full image — wrap the image in a link to the full-size file with a built-in lightbox.
• Metadata — resolution (width×height) and file size are shown before insertion, with a live thumbnail preview.

You can select multiple images (multi-select) and insert them as a gallery using the [kda_media_button_gallery] shortcode:

File management

Inside the popup you can also manage the folder structure:

• Create new subfolders.
• Rename files and folders.
• Delete files and folders (recursive).

Security

• Folder traversal outside the configured base folder is blocked.
• Uploaded files are validated against the allowed formats list and handled through the WordPress upload API.
• All AJAX requests are protected with nonces and role/capability checks.
