How Can I Insert Data To Database Through Ck Editor

You need to get the data (content) from the editor and then save that in your database.

From their documents[^], you can use this code,

// editor1 is the instance ID of the editor. 
var data = CKEDITOR.instances.editor1.getData();

Now once taken, you can use the variable data in your code to send the content to the server and save it. You can use POST requests, or the Ajax to send the data and so on and so forth. You should go to the documents and read more on this.
