Displaying Images Based on Checkbox Values in ACF

If you're working with WordPress and utilizing Advanced Custom Fields (ACF), you may encounter a situation where you need to show different images based on which checkboxes a user selects. For example, you might want to show an image corresponding to each of the values checked from a checkbox field. In this post, we'll break down how to implement a switch case structure to achieve this functionality while ensuring it works seamlessly even when multiple values are selected.

Understanding the Problem

You have a checkbox field in ACF that allows users to select up to two options from five available choices labeled A, B, C, D, and E. Based on what the user selects, you want to show specific images. However, the challenge arises when trying to implement this using a switch case statement in PHP. A traditional switch case will struggle with handling multiple values efficiently, and that's where our solution comes in.

The Solution: Using Conditional Logic

Instead of relying solely on a switch case structure, we can leverage conditional logic to check for the selected checkbox values. Here's how to do that step by step:

1. Setting Up Your Checkbox Field

Make sure your ACF checkbox field is properly set up with the five options:

A

B

C

D

E

Also, set a conditional logic rule in your ACF settings to limit users to selecting a maximum of two checkboxes.

2. Fetching Checkbox Values

First, you need to fetch the selected values from ACF. Here's how you can do that:

3. Implementing Conditional Logic

Next, instead of a switch case, use conditionals (if statements) to check for combinations of selected values. Here's a sample code snippet to illustrate this:

4. Expanding on the Logic

You can easily expand this logic for other combinations of checkbox values. Just keep adding elseif statements to check for different pairs or individual selections based on your requirements.

Conclusion

By utilizing conditional logic instead of a traditional switch case, you can effectively manage multiple checkbox selections in ACF and display images according to user preferences. This method gives you the flexibility to present combinations of selected values seamlessly. Start implementing this in your WordPress site today and enhance your user experience!
