You'll learn how to create an app with features similar to Reddit, integrate AI like OpenAI for text and image generation, and much more.

Setting Up the Upvote Downvote Functionality in Bubble

To get started, we need to add workflows to both the upvote and downvote buttons. Here's how:

1. Add a workflow action to make changes to the parent group's post
2. For upvote: Add current user to "upvoted by" field and remove from "downvoted by"
3. For downvote: Add current user to "downvoted by" field and remove from "upvoted by"
4. Update the post's score based on the user's action (+1 for upvote, -1 for downvote)

To prevent multiple upvotes or downvotes from the same user, add conditional logic:

• Only allow upvote/downvote when the user is not already in the respective field
• Adjust score by +1/-1 when fields are empty, or by +2/-2 when switching vote

Enhancing the User Interface with Conditional Styling

Make the upvote/downvote feature more intuitive and engaging with conditional styling:

1. Highlight buttons when the user has interacted by changing icon color
2. Check if current user is in "upvoted by" or "downvoted by" fields
3. Apply hover effects to improve user experience

Testing and Refining the Upvote Downvote System

Before finalizing your app, thoroughly test the upvote/downvote functionality:

• Preview the app to ensure score updates correctly and multiple votes are prevented
• Adjust the app's design for better visual appeal and readability
• Consider adding default images for posts without user-uploaded images

By following these steps, you'll have a fully functional upvote/downvote system that engages users and enhances the overall experience of your Bubble app.

FAQ (Frequently Asked Questions)

Can I add the upvote/downvote feature to any Bubble app?
