What does the name attribute do in form sub-elements?

The name attribute provides the variable name for a control element on a form.

<form>
...
	<input type="text" name="fullname">
...
</form>

The variable name in this case will be "fullname". When a user enter the name, the variable will be associated with that value: "fullname=My+Name".

All form control elements (except submit and reset buttons) must have a name attribute so the form processing application can sort the information.
