How are forms used in an MVC framework?

Question

i have been doing simple MVC tutorials for a while and i get the concept. But i am wondering, when a form is displayed in a view, how is the form processed? A code to check for form submission must be present in the view file, which doesn't really fit because view should just be for displaying output.

So when you have a form in a view file of an MVC framework, where should the code to check for form submission be?

Answer 1

Of course this depends on the specific framework, but this is rather typical:

• form data is posted to a controller (like all requests)
• data validation rules are defined in the model
• the controller runs the data through the model for validation
• if successfully validated, the controller does whatever it's supposed to do
• if data is invalid, the controller pushes error messages for invalid fields to the view
• the view just displays the error messages

Answer 2

The form submission can be handle in controller. check this
