How do I prevent user content from getting lost in CKEditor 4?

To migrate form CKEditor 4 to CKEditor 5, follow the steps given below: 

Remove CKEditor 4 from your project. 

Install CKEditor 5 via npm or CDN:

Update your JavaScript code to initialize CKEditor 5 instead of CKEditor 4. Example:

Check the plugins that you used in CKEditor 4 and find their CKEditor 5 equivalents, as architecture of plugins is different. 

If you used custom plugins or configurations, rewrite them using CKEditor 5’s new API and plugin system. 

Test your editor to make sure that everything works as expected with CKEditor 5’s modern features and UI.

To upload files and images in CKEditor 4, follow the steps given below:

Download CKEditor from its official website.  

Make sure you use the 'Standard' or 'Full' build, as these include the necessary plugins for file uploads.

Navigate to your CKEditor configuration file (typically

config.js

).

Add this line to enable file upload:

This points to a server-side script (e.g.

upload.php

) that handles the actual file uploads.

After setting everything up, open CKEditor and use the image or file button to open the dialog box. 

In the dialog, you will see an Upload tab where you can select a file from your computer and upload it to the server.

Create the

 upload.php 

file (or use another server-side language) to handle the file upload logic.

Configure the script to store the files on your server and return the file path to CKEditor after a successful upload. 

After setting everything up, open CKEditor and use the image or file button to open the dialog box. 

In the dialog, you will see an Upload tab where you can select a file from your computer and upload it to the server.
