How Freshy streamlined custom RMA form functionality for a WordPress support portal

A client’s WordPress-based support portal required updates to its Return Merchandise Authorization (RMA) form. The request seemed straightforward — adding three new product model groups to a dropdown selector. However, as Freshy’s development team quickly discovered, the form was built on deeply customized PHP logic, requiring precise backend integration to maintain stability and performance.

Issue background

The site’s RMA system was powered by Formidable Forms and tied into a custom post type (rma_posts). Each RMA entry in the database was dynamically generated and displayed via a shortcode ([rma_list_show]) that pulled and rendered data from these posts into a sortable table.

The client requested that three new model categories — ASYS Counter, C3 & LC-23, and C5, E3 & E7 — be added under the Module Info section of the form. While this initially appeared to be a simple form update, the fields were tightly connected to backend logic and WooCommerce product data.

Diagnosis

Upon investigation, the assigned developer found that:

• The form fields were directly connected to backend PHP functions via hooks like frm_setup_new_fields_vars and Formidable’s custom meta queries.
• Dropdown data was populated dynamically from WooCommerce categories tagged as “Repairable.”
• Any addition to the form required backend updates to field references, validation logic, and query conditions.
• The existing shortcode logic rebuilt the RMA table by matching post_id references between Formidable entries and custom post types — meaning that any new fields also needed to be stored and retrieved consistently.

This meant the updates could not be handled solely within the Formidable Form UI; backend PHP integration was essential.

Resolution steps

The developer implemented the following process:

1. Reviewed and mapped all relationships between form fields, database entries, and shortcode logic.
2. Extended the query structure that drives dropdown options to include the new product categories:

SELECT products 
WHERE category = [selected category] 
AND meta_key = 'Repairable' 
AND meta_value = 'Yes';

3. Updated backend handlers to correctly save the new module data to the associated RMA post when a submission was made or edited.
4. Conducted end-to-end testing in both RMA and “Pending Core Return” views to confirm that module selections persisted across all displays.
5. Corrected a category naming discrepancy (“C3 & LC-23” vs “C3 & LM-23”) to align with existing WooCommerce taxonomy.
6. Validated performance of the form under load, noting that certain admin-side API processes caused timeouts — a potential area for future optimization.

After the adjustments, module selections were successfully saved and rendered within all relevant RMA views.

Final outcome

The custom form updates were completed and verified, restoring full functionality while preserving the site’s complex RMA workflow. Freshy’s thorough discovery process and backend development ensured that the system’s logic remained stable despite its custom structure.

This case highlights the importance of understanding the interplay between WordPress plugins and custom PHP code when handling advanced site functionality. Even small front-end form changes can have ripple effects across a highly integrated backend.
