Creating the Form

Finally, you can work on the form. You need to allow for two form fields — a name and an email. You

also know that you need to post to welcome/subscribe. That ’ s all you really need in order to create the

form. In the example below, fieldsets and labels are used, but other approaches are equally valid.

One important note: The Subscription form has been added to the home view. As you can see, it is a

simple form that prompts the user to fill in his name and e - mail address. In this particular case, the

example uses a fieldset to delineate the form, but you could use any visual design convention to separate

it from other parts of the page.

echo anchor(‘welcome/product/’.$mainf[‘id’],’see details’). “ < br/ > \n”;
