Post values from an HTML form and access them in a Flask view

Question

I have an HTML form that gets posted to a Flask route. However, request.form is empty. If I try to access one of the values by id, I get a 400 error. How do

Answer 1

Your input doesn't have a name attribute. That is what the client will pass along to the server. Flask will raise a 400 error if you access a form key that wasn't submitted.
