4. Customer account existance verification on email field durring checkout

This is allows for custom checkout workflows to direct existing customers to login at checkout. Example: http://electricquilt.com

This is an advanced feature intended to help reduce the work on custom checkout workflows. It is not a "turn it on and it just works" feature and involves adding code to your custom checkout theme template.

How to use the customer account existance verification on your Shopp

1. In your custom Shopp checkout theme template:
   1. Add this code to the top of the template:

   <?php 
   $customer_email = shopp('checkout','get-email','mode=value'); 
   $customer_exists_class = '';
   if( !empty($customer_email) ) {
   	$customer_exists = shopp_customer_exists($customer_email, 'email'); 
   	$customer_exists_class = ' user-not-exists';
   	if( $customer_exists ) $customer_exists_class = ' user-exists';
   }
   ?>
   

   2. Change the class attribute on your <form> to include the following at the end:

   <?php echo $customer_exists_class; ?>
   

   3. Change your 'account-login' theme api call to something that resembles the following:

   <?php shopp('customer','account-login', array('value' => $customer_email, 'data-customer-lookup-last-success-return' => $customer_email)); ?>
   <input id="check-for-customer" type="button" value="Next">
   

2. The customer account existance should now be working.
   1. If an account with the customer's email exists, a "user-exists" css class is added to the shopp checkout form:
      • The css selector for this is #shopp #checkout .user-exists.
   2. If an account with the customer's email does not exist, a "user-not-exists" css class is added to the shopp checkout form:
      • The css selector for this is #shopp #checkout .user-not-exists.
3. Use custom css in your custom shopp theme to show/hide or change the look of elements based on whether the customer has an existing account or not.
