POST method, Ajax and security?

Question

I am using Ajax (jQuery) and the POST method to update the data in the database. I do the following:

• Get data from the form: user_id, entry_id, content, ...
• Send them to the URL that will process the data.
• If the data is valid, we will record it in our database.

I do not know how to verify that the user is sending data from my site, and not from other places. Please help me solve this problem. Thank!
