Creating a generic form element generator
It's pretty easy to create a function that simply outputs a form input tag such as
<input type="text" name="whatever" >. In order to make a form generator generically useful, however, we need to think about the bigger picture. Here are some other considerations over and above the basic input tag:
- The form

- A label that tells the user what information they are entering
- The ability to display entry errors following validation (more on that later!)
- Some sort of wrapper, such as a
<div>tag, or an HTML table
How to do it...
- First, we define a
Application\Form\Genericclass. This will also later serve as a base class for specialized form elements:
namespace Application\Form; ...
