It is a lot of code having to check the login variables inside the POST handler, and i could not mark each input field individually as invalid because the generic errors array i was using did no identify which field had the error. Thus, i use more or less the same technique as with Numerus: a struct with the value and the error message. This time the input field does not have the label and extra attributes because i believe this belongs to the template: if i want do reuse the same form template, i should create a common template rather than defining everything in Go. The name is a bit different, however, because it has meaning both to the front and back ends, as it needs to be exactly the same. Writing it twice is error-prone, as with a rename i could easily forget to change one or the other, and here i see value in having that in Go, because it is also used in code.
