We were recently brought into a project (under NDA, so no names!) to fix a WooCommerce conditional discount plugin issue that had become a major source of chaos.
The site used the Conditional Discounts for WooCommerce plugin to offer discounts when a customer’s basket exceeded a certain value.
After a WooCommerce update, something strange started happening…
🧩 The Problem: A Discount Loop
Instead of applying the discount once and moving on, the plugin triggered an endless loop:
- Basket total is above the threshold ➡️ Discount applied
- Discount brings basket below the threshold ➡️ Discount removed
- Removal puts basket back above the threshold ➡️ Discount applied again
…and repeat. Forever.
The site stuttered, recalculated, and sometimes even blocked checkout.
It was a perfect example of a WooCommerce conditional discount plugin issue gone wrong.
The plugin developers admitted the problem — but their only advice was to roll back WooCommerce.
That’s not exactly a long-term fix.
🧠 Our Approach: Debugging the Plugin
The agency had already done some great groundwork and passed us everything they’d discovered.
They activated our free 2-hour development offer, and we got straight to work.
Using XDebug and VS Code, we traced the logic to the exact point where the plugin decided whether to apply a discount.
From there, we found several helpful filter hooks.
These hooks let us intercept and control the evaluation logic — giving us the flexibility to create a stable, long-term WooCommerce plugin fix.
🔧 The Fix: Creating a Stable WooCommerce Solution
We used those hooks to:
- Inspect the cart manually
- Apply our own logic to check discount eligibility
- Ensure consistent results (no more oscillating yes/no loop)
We wrapped everything into a clean, custom plugin and handed it back to the agency.
We also provided a short walkthrough and highlighted a few caveats around tax handling.
Everything was completed in just two hours.
✅ The Outcome: WooCommerce Conditional Discount Plugin Issue Resolved
- The discount rule worked again — no more infinite loops.
- The agency was happy.
- The client’s issue was resolved quickly and professionally.
And best of all, no one had to roll back WooCommerce. 🎉
We’ve made the WooCommerce conditional discount plugin issue solution available on our GitHub repo in case anyone else runs into the same WooCommerce discount loop problem:
