Hi everyone!
I wanted to share a clever workaround I recently implemented in Gravity Forms to replicate more complex conditional logic that isn’t supported natively — specifically, the scenario:
`A AND (B OR C OR D)`
Since Gravity Forms doesn’t support nested AND/OR conditional logic out of the box, I used a Number field (with calculation enabled) to mimic this behavior without any custom code. Here’s how I did it:
The Challenge
I needed to only show a message or block a form if:
- One primary condition (A) was met (e.g., a specific eligibility question), and
- At least one of three other supporting conditions (B, C, or D) was not met (e.g., funding amount, sector, or project impact).
This can’t be done directly in Gravity Forms’ conditional logic UI.
My Workaround: Using a Number Field (No Custom Code!)
I assigned numeric “scores” to each field’s possible values:
- Primary Condition (A): 100 if the response met the criteria, 1 if not
- Supporting Conditions (B, C, D) (different dropdowns/radios):
- Good values: 33, 34, 35, 36
- Bad values: 1
I created a Number field and enabled the option “Enable Calculation” (I named this field “Importance”), with the formula:
`A + B + C + D`
I then added a conditional HTML field (for warnings or messages) with conditional logic:
`Show this field if Importance < 100`
How It Works
This ensures that:
- The primary condition (A) must have the highest score (100).
- At least one of the supporting conditions (B, C, or D) must not have a “good” score (1 instead of 33+).
- If not, the total score stays below 100 and triggers the warning message.
It’s a simple numeric trick to simulate A AND (B OR C OR D) logic — with no custom code needed!
Why I’m Sharing
I’ve seen other users struggle with this type of nested logic in Gravity Forms — so I hope this helps! Let me know if you have any questions or tweaks — or if you’ve used a similar approach!
Happy to share screenshots or more details if needed.
