In a registration form for example, there are individual inputs like name and address. Where you have a list however, you need to add more input fields, one for each entry, which in IMO, is not very efficient, and it lengthens the webpage unnecessarily, depending on the length of the list. The inefficiency is that PHP get and post only read values from html inputs. If instead of adding perhaps a large number of inputs, a storage attribute for inputs
<input type="text" name="Object" storage="ObjectList">
Where an input requires a list, two or more, an array variable called ObjectList would be created in JavaScript or other, to store the list, which could then be read by PHP get and post. Just an idea.
