How do I edit inspect element, but it won't make any changes after submitting it?

I already disable editing for php where the user can no longer edit on the form itself, but now I want to edit inspect element, but when I click submit, no changes will be made. I need to change the coding in the request form, but I have no idea what to write.

Explanation

So basically, right now when I open the website I need to fill in the form. I want to disable some text box from editing, so the user won't be able to update their info. However, the user can still right click and update through inspect element and when the user click submit, the data will be submitted. So now what I want to do is, even after the user edit through the inspect element, but when the user click on submit, the data won't pass through and there will be no changes.
