Well, your frontend should never send the payment value to the server. You should only show the results on the frontend and calculate the final prices in the backend on payment.

hm.. you cant prevent a field from being changed BUT with paypal once user gets to the checkout stage, and clicks pay you store their basket etc in the db - send them to paypal and then after they are paid paypal sends them back (or pings a url on your side with transaction info) - you can then check if what they paid was what was on their basket...

i am not sure if paypal payment have changed/added more methods since I used it few years back..

(I would also use stripe/braintree where you charge the user from the backend)

okey but how can i send data to paypal with out form , paypal requires form like this of product name ,,

etc

Well right now you show items/products on your webpage right? And you let people pay from there right? You can retrieve those products again, calculate the price and redirect them to the paypal payment page. That's it.

I calculated them in the back and But the problem if any
