Stripe Billing Address Mapping Bug in Formie

Hey guys! Today, we're diving into a pretty specific but super important bug that some of you might be running into with the Formie plugin and its integration with Stripe. If you're using Formie to collect payments and have noticed that your customer's billing address isn't quite mapping correctly to Stripe, you're in the right place. We've uncovered a bug where the billing address is showing up with a weird .__toString appended to it in the provider settings. Let's break down what's happening, why it's a bummer, and how we can get it sorted.

The Nitty-Gritty: What's Going Wrong?

So, the core issue here is with how Formie is handling the billing address when you're setting up the Stripe payment field. When you go into your provider settings for Stripe and try to map your form fields, you'll see the billing details section. Normally, you'd expect to see clean field mappings like {field:customerName} for the name and {field:emailAddress} for the email. But when it comes to the billingAddress, things get a little messy. Instead of mapping directly to a clean address field, it's showing up as {field:shippingAddress.__toString}.

Why is this a problem? Well, .__toString isn't what Stripe expects for an address. Stripe needs a structured address object with fields like line1, city, postal_code, country, etc. Appending .__toString suggests that Formie might be trying to cast the entire address field object to a string in a way that isn't compatible with Stripe's API expectations. This means that the actual address details aren't being sent to Stripe correctly, which can lead to all sorts of headaches down the line, like incorrect invoicing, issues with fraud detection, or just plain missing data in your Stripe customer records.

Let's look at the configuration:

[
  "integration" => "verbb\formie\integrations\payments\Stripe"
  "type" => "single"
  "amountType" => "dynamic"
  "currencyType" => "fixed"
  "billingDetails" => [
    "billingName" => "{field:customerName}"
    "billingEmail" => "{field:emailAddress}"
    "billingAddress" => "{field:shippingAddress.__toString}" 
  ]
  "metadata" => []
  "currencyFixed" => "USD"
  "amountVariable" => "{field:total}"
]

See that billingAddress line? That's the culprit. We want it to be a proper mapping to an address field, not this string representation.

Reproducing the Bug: Simple Steps, Big Impact

Reproducing this bug is thankfully pretty straightforward, which is good news for developers trying to fix it. The steps involve setting up a typical payment form in Formie. Here's the rundown:

  1. Create a New Form: Start by creating a new form in Craft CMS using the Formie plugin. Let's call it something like "Stripe Payment Form".
  2. Add Required Fields: You'll need a few fields for this. At a minimum, you'll want:
    • A Name field (e.g., customerName)
    • An Email field (e.g., emailAddress)
    • An Address field. Formie has a dedicated Address field type which is ideal here. Let's call this shippingAddress for demonstration, though it's being used for billing.
    • A field to determine the amount, like a Number or Total field (e.g., total).
  3. Add the Stripe Integration: Go to your form's settings and navigate to the "Integrations" tab. Click to add a new integration and select Stripe.
  4. Configure Stripe Settings: Now, this is where the magic (or bug) happens. In the Stripe integration settings, you'll need to configure the payment details. Set:
    • Type: Choose single or variable depending on your needs. For this example, let's assume dynamic amount.
    • Amount Type: Set this to dynamic and map it to your total field.
    • Currency Type: Choose fixed and set your currency (e.g., USD).
  5. Map the Billing Details: This is the critical step. Under the Billing Details section:
    • Map the Name field to your customerName form field.
    • Map the Email field to your emailAddress form field.
    • Map the Address field to your shippingAddress form field. This is where the bug manifests. Even though you're selecting the Address field, Formie incorrectly maps it as {field:shippingAddress.__toString}.
  6. Save and Check: Save your Stripe integration settings. Then, go back and check the settings again. You should now see the billingAddress incorrectly mapped as {field:shippingAddress.__toString}.

Form Settings Considerations:

The specifics of your form settings might influence the user experience, but they don't seem to directly cause or fix this particular mapping bug. Whether you use a:

  • Multi-page form: Yes or No
  • Submission Method: Ajax or Page Reload
  • Client-side Validation: Yes or No
  • Custom Form Templates: Yes or No

...the bug in the Stripe integration's billing address mapping will likely persist. The core issue lies within how Formie's Stripe integration is processing and passing the address data, regardless of the form's overall structure or submission method. This means even if you have a super slick, multi-page form with Ajax submission, the underlying mapping problem will still be there.

Affected Versions: Craft CMS and Formie

To make sure we're all on the same page, let's highlight the software versions involved in this reported bug. This helps in understanding the scope and ensuring you're running software that might be affected or has a fix available.

  • Craft CMS Version: The report indicates this bug was observed on Craft CMS 5.8.17. While this is the specific version noted, it's always possible that similar issues could exist in slightly older or even newer minor versions of Craft CMS if the underlying plugin architecture or dependencies are involved. It's good practice to keep your Craft CMS installation updated to the latest stable release to benefit from security patches and bug fixes.
  • Formie Plugin Version: The bug was specifically identified within Formie version 6.10.1. This is a crucial piece of information. If you are running this exact version of Formie, you are likely to encounter this billing address mapping issue. Conversely, if you are on an older or newer version, the situation might be different. Plugin developers often release patches or updates to address bugs like this, so checking for updates to Formie is a priority.

Important Note: If you're running a different combination of Craft CMS and Formie versions, it's still worth investigating if you're experiencing similar symptoms. Bugs can sometimes creep into multiple versions or be fixed in unexpected releases. Always refer to the official plugin changelogs and documentation for the most accurate information regarding bug fixes and compatibility.

Potential Workarounds and Next Steps

Okay, so we've identified the bug, seen how it happens, and know which versions are affected. What now? Dealing with bugs can be frustrating, especially when they impact critical payment integrations. But don't worry, guys, there are usually ways to work around these issues while waiting for an official fix.

1. Manual Mapping (If Possible):

Sometimes, the issue isn't that the data can't be sent, but that it's being sent in the wrong format. If Formie allows you to manually define the structure of the address being sent to Stripe, that might be a way forward. However, given the .__toString issue, this might be tricky. You'd need to ensure you're mapping individual components of the address (like street, city, postcode, country) to their corresponding fields in Stripe's expected format, rather than trying to map the entire Formie address field object.

2. Separate Address Fields:

Could you try breaking down your address field into individual text inputs for street, city, postcode, and country? Then, you could map each of these individual fields to the corresponding Stripe billing address components. This is more work on the form design side but might bypass the problematic object-to-string conversion that Formie is doing.

3. Check for Updates:

This is the most obvious but often overlooked step. Head over to the Verbb website or the Craft CMS plugin store and check if a newer version of Formie has been released since 6.10.1. The developers might have already squashed this bug. If an update is available, always back up your site before updating, and then proceed with the update. Read the changelog carefully to see if the billing address issue is mentioned.

4. Report the Bug:

If you've confirmed you're on the latest version and the bug still exists, or if no update is available, the best thing you can do is report it directly to the Formie developers. Provide them with all the details you have: the exact steps to reproduce, your Craft CMS and Formie versions, and the configuration snippet. This is how bugs get fixed! You can usually find a support or bug reporting section on the developer's website (Verbb in this case).

5. Consider Alternative Integrations (Temporary):

As a last resort, if this bug is severely blocking your payment processing and you need an immediate solution, you might have to temporarily disable the Formie Stripe integration and use a different method for collecting payments or capturing the address data. This isn't ideal, but sometimes a temporary workaround is necessary to keep things moving.

The Bigger Picture:

While this specific bug is about address mapping, it highlights the importance of thorough testing for integrations, especially those dealing with sensitive financial data. Developers work hard to make these plugins seamless, but edge cases and bugs do happen. Staying informed, checking for updates, and actively participating in the reporting process are key to maintaining a healthy Craft CMS ecosystem. Hopefully, this bug will be resolved swiftly, and your billing addresses will start flowing to Stripe without a hitch!

Keep an eye on the Formie plugin updates, and happy form building, everyone!
