I am building a website for a customer who may not be very computer literate. This person knows how to use email. How can I build a website (purely html, javascript) where he can email his latest prices and the website automatically updates itself. I dont think he would be literate enough to FTP file some where. Is it possible?
How to build a secure login page and redirect to order page using only javascript and html?
How to create secure administrative section on javascript/html only website?
I would advise you to create a nice admin web interface, and teach him how to use it. Or, agree some kind of Excel format for product prices, and teach the steps of uploading a csv file. Doing things by email would complicate things in my opinion.
