This form uses a horizontal layout, which is different from the email form. There is no checking of any of the data. All this demonstrates is posting the data, which should appear above in the header once it is posted.
It goes from this form back to the controller where the $_POST array is read, and then comes back to this form as local variables, which I have set to be the "name" attrfibute of the text boxes on the form. The data is not stored.
