Header Domain Search

Use this setup when you want a small header form that starts a domain search, then lets the customer choose from available domains inside the Ultimate Multisite checkout.

Requirements

• Ultimate Multisite network-active.
• Multisite Ultimate Domain Seller network-active.
• At least one active domain registration product with:
  • domain_provider set to a configured provider.
  • Supported TLDs configured, for example com, net, and org.
• A valid checkout form containing the Domain Selection field.

Checkout form

1. Create or edit the checkout form used by the registration page.
2. Add the normal required checkout/account fields, including Username. A checkout form containing only the domain field is rejected by Ultimate Multisite validation.
3. Add a Domain Selection field.
4. Set the Domain Selection mode to Register Only when the flow should focus on registered domains rather than free subdomains or existing domains.
5. Assign the domain registration product to that field.

The registration page should render the checkout form, for example:

[wu_checkout slug="domain-form"]

Header form

Add a small GET form in the site header that sends the entered search term to the checkout page as domain_name:

<form class="ums-header-domain-search" action="/register/" method="get">
  <label class="screen-reader-text" for="ums-header-domain-search-input">Search for a domain</label>
  <input id="ums-header-domain-search-input" name="domain_name" type="text" placeholder="Find your domain" autocomplete="off">
  <button type="submit">Search</button>
</form>

Do not preselect a domain in custom header JavaScript. The header should only pass the search term. The Domain Seller checkout script reads ?domain_name=example, fills the checkout search box, and runs the availability search so the customer can choose from the returned domains.

Expected behaviour

Searching example in the header should open:

/register/?domain_name=example

The checkout should then display selectable results such as:

• example.com
• example.net
• example.org unavailable
• other provider-supported TLDs

After selecting an available result, the order summary should include the domain registration product and the selected domain name.

Verification

1. Open the home page.
2. Search for a bare name, for example example.
3. Confirm the checkout URL includes ?domain_name=example.
4. Confirm the checkout domain field contains example.
5. Confirm a list of domain choices appears.
6. Click Select for an available domain.
7. Confirm the order summary contains Domain Registration - example.com or the selected domain.

Troubleshooting

• If no list appears, check the browser network tab for admin-ajax.php?action=wu_domain_search and confirm it returns non-empty domains or results.
• If the checkout form fails validation while saving, add the required account fields such as Username.
• If selecting a domain does not update the cart, confirm window.wu_checkout_form exists and that the Domain Seller checkout assets are loaded on the checkout page.
