Case description: “Flexible Checkout Fields PRO data doesn't appear in the order”
A WooCommerce user used the plugin’s feature to add custom fields to the checkout page. Customers could see the fields displayed correctly during the order process. However, customers entered data into the fields, but it didn’t appear in the order details in the admin panel.
First, we confirmed that the fields were configured correctly. The fields were active and assigned to the correct checkout sections. Yet, the system didn’t pass the entered data to the order.
Case analysis and solution
Step 1: Test orders
To diagnose the issue, we placed two test orders. This confirmed that the field data indeed wasn't being saved, even though the customer filled in the fields.
This made it clear that the problem wasn’t in the plugin’s field settings, but rather in how the checkout page processed the data.
Step 2: Reviewing the checkout page setup
During the analysis, we noticed that the user built the checkout page using the Divi visual editor. While Divi is one of the most popular page builders for WordPress, it’s not compatible with the mechanism used by Flexible Checkout Fields PRO.
Why?
Page builders like Divi often override WooCommerce’s default structure, which can prevent additional field data from being passed to the order.
Important:
Flexible Checkout Fields works properly only on a classic checkout page built using the shortcode [woocommerce_checkout].
Step 3: Creating a new checkout page
To restore full functionality, we created a new checkout page in WordPress. We added only the following shortcode to the page: [woocommerce_checkout]
We published the page and set it as the default checkout page in:
WooCommerce → Settings → Advanced → Checkout page
We avoided using any visual editors on this page, which was crucial for ensuring full plugin compatibility.
Step 4: Final test – data from Flexible Checkout Fields PRO was saved correctly
After switching to the new, classic checkout page, we placed another test order.
The data entered into the custom fields appeared correctly in the order details in the WooCommerce admin panel. The plugin worked exactly as intended, and no reconfiguration of the fields was needed – the correct checkout structure was all it took.
