Install file manager plugin for CKEditor 4
Enable
Find the place in your HTML/JavaScript code where you load CKEditor 4 and enable the file manager add-on in the initialization parameters:
In config.js
Initialization script
CKEDITOR.editorConfig = function(config) {
config.extraPlugins = "file-manager";
config.Flmngr = {
apiKey: "FLMNFLMN", // Default free key
// Get free own API key to use with a visual configurator:
// https://flmngr.com/dashboard
};
// Toolbar is configured automatically
}
Install the backend
Now you need to install the file manager server-side script somewhere on your server. There is a manual behind the link on how to do it and link the backend with the Flmngr CKEditor plugin.
Ready to use
Customize

We recommend you to register a free own API key to configure Flmngr visually using Dashboard. Or you can configure it by passing API parameters directly. There is also a short FAQ related to CKEditor 4 plugin.

If you need to use Flmngr outside of CKEditor 4 on the same page, you can get its object and call it from JavaScript to ask it to pick files, upload an image, etc.
