MailChimp is a high-octane sportscar for concocting and delivering permission-based email marketing campaigns. It's simple, powerful, and more fun than a barrel of… well, monkeys.
This script does the following:
Included for good measure are the PHP MailChimp API interface, a PHP4-compatible XML parser, RC4 decryption library, and a test harness.
// ... $MailChimp_Auth = array( 'apikey' => 'put your API key here' // Use an MailChimp API key to connect to MailChimp. ); /** * Use a custom field during checkout? If true, check for the presence of $Custom_Field below. * If false, always subscribe the customer. Use wisely. */ $Use_Custom_Field = true; $Custom_Field = 'Subscribe'; // Name of the custom "Opt In" field during checkout. $Custom_Field_Value = 'yes'; // The value of the custom field that indicates the customer's agreement. $Email_Format = 'html'; // The customer's preferred email format. $Send_Confirmation = true; // If true, MailChimp will send a confirmation email to the customer. $List_Name = 'My Awesome List'; // The exact name of your mailing list. No List ID required, we'll look it up. $key = 'CHANGE THIS TEXT to your own datafeed API key'; // EDIT: Use here your FoxyCart Datafeed API key visble under "Store-->Advanced Settings" // ...

test.xmldatafeed.php, then open
http://your.domain.dom/path/to/test.xmldatafeed.phpin your browser. You should get a page that contains only the word
foxyin reply. If you get something else, double-check your datafeed keys in both files and, if all else fails, pop on by the forums.
Now you have a datafeed receiver all set up on your server, so it's time to let your customers opt in to your mailing list. To do that, we need to add a Custom Field to your checkout template, so that your customer sees a “Subscribe” checkbox alongside their cart contents. There are a lot of cool things possible custom fields; find out more at the wiki page on Custom Fields. Today we're only going to add a single checkbox to the checkout template. Open the template up in your editor (if it's hosted on your server) or edit it directly from the FoxyCart admin interface, and add the following block of code anywhere in the template:
^^custom_begin^^ <h2>Newsletter</h2> <fieldset id="fc_custom_fields"> <legend>Newsletter</legend> <div class="fc_inner"> <div> <h4>Subscribe</h4> <input type="checkbox" name="Subscribe" value="yes" checked="checked" /> <label for="Subscribe">Leave this box checked to receive occasional updates about our products. We will not share your email address, and you can unsubscribe at any time.</label> </div> </div><!-- .fc_inner --> </fieldset><!-- #fc_custom_fields --> ^^custom_end^^
You can put the code at the end of the file, or at the beginning – it doesn't matter. FoxyCart will move the
<fieldset> into the checkout form when it loads your checkout page, so it can even be after the
</html> tags. Replace “Newsletter” and “occasional updates about our products” with whatever's appropriate for your mailing list.
Save your changes to the checkout template in the FoxyCart admin. Test by adding a product to your cart and going to checkout – you should have a shiny new “Subscribe” checkbox, all primed and ready for your customers to use.
