HTML Checkout Address Form with Shipping Autocomplete

A form should feel easy to use. The visitor sees a question, gives an answer, and needs to know what will happen next.

What You Need to Know

This example puts a readable label next to each control and gives each submitted value a name.

Try the Example

Take a look at the example. We’ll explain the important lines right below it.

<form action="/submit-checkout" method="post">
    <label for="street-address">Street address</label>
    <input id="street-address" name="street-address" type="text" autocomplete="street-address" required>
    <label for="postal-code">Postal code</label>
    <input id="postal-code" name="postal-code" type="text" autocomplete="postal-code" required>
    <button type="submit">Continue</button>
</form>

Let’s Read the Code

autocomplete: Autocomplete tells browser autofill what kind of information belongs here.
<form>: The form groups controls and identifies where submitted data goes.
<label>: The label tells people what the input is for. A matching for/id pair makes the label clickable.
for: For connects a label or output with a control by ID.

What the example shows: A browser can display and check the fields, but an address such as /submit-contact needs server code to actually save a response.

What Happens in the Browser?

The HTML controls work in the browser, but saving an answer requires the example action path to be handled by a real server.

Where does the answer go? The example uses the submitted name(s) street-address, postal-code. Those names help the receiving server identify each answer. A label is for people; a name attribute is for the form data; an ID connects elements in the page.

Your Turn

Change one label and one name attribute. Which change affects what people see, and which changes the name sent to the server?

Common Beginner Mistakes

Using an autocomplete token as validation instead of a hint for browser autofill.
If this page is opened as a local file, it will display, but its submit destination is only an example until you build a server endpoint.

Key Takeaways

A control needs a clear label and, when submitted, a meaningful name and value.
autocomplete: Autocomplete tells browser autofill what kind of information belongs here.
Remember that HTML form rules help the visitor, but server-side code must decide whether received data is valid.
