Forms allow users to enter and submit data.
For example, we can use forms to handle logins, order forms, and user feedback. The form tag
requires two attributes – action and method. Action is the location where the form is sent
to. This can be either an email link or a form handling script. A from handler requires
server-side programming and uses the Common Gateway Interface (CGI), both of which will
be covered in different tutorials. The other required attribute is the sending
method, which can be either GET or POST. GET sends the form data directly when it calls
the form handler by appending the data to the URL. POST, on the other hand, sends the
data to the handler in a separate transmission. Which method we should use may depend on the
form handler. Inside of the form tag we may place any elements
we want, but most importantly we may here include the form controls.
Most controls uses theelement which lets us create buttons, text fields, and alternatives.
Almost every form control requires a name and a value to either be specified in the
markup or entered by the user. These name value pairs are what is later sent to the
form handler. Every form needs a submit button which send
the form to the handler. We can also add a reset button for resetting the form to its
initial values. The default text label can be changed using the value attribute. Additionally,
we can add custom, normal, or image buttons. However, to give them any functionality requires
Another way to make custom buttons is using the
