I want to create a Feedback form for my website with rating system, which will then display the monthly average rating to a separate page as a graph.

I do have a little concept. But It's lacking something. I know how to create a feedback form. But I am confused on how to save it in Mysql. I mean do I need to calculate the average rating before saving it to mysql or when calling from the graphs page.

Please help me with concept or example.

Thanks.

You will have a form, where the user will put all the rating and the info.

When the user press the "Send" button you will execute a PHP code, this script will take the value of the form, and insert them inside a database, with the current year / month.

When you will go on the page that will show the rating you will execute a php code that will take all the rating in the current year/month from the database , sum them, and do the average calculation. Then you will show the value.
