How to add like and dislike in Bubble

The simplest valid way to add like/dislike in Bubble is to store them as Lists of Users on the content thing (for example, a Post). Then your workflow only adds or removes the Current User from those lists when the user taps Like or Dislike. Bubble handles the list updates automatically, so you don’t need custom code.

Data structure

• Create or open your data type, for example Post.
• Add a field Likes (type: User, make it a list).
• Add a field Dislikes (type: User, make it a list).

This lets each Post store who liked or disliked it.

Like button workflow

• When Like button is clicked, add a workflow: Make changes to a Post.
• If Current User is already in Likes, remove them. Otherwise add them.
• Also remove the user from Dislikes to avoid having both.

// Inside "Make changes to Post"
Likes add Current User       // or remove if already in list
Dislikes remove Current User // prevents double reaction

Dislike button workflow

• Do the same but reversed: manage the Dislikes list and remove from Likes.

// Inside "Make changes to Post"
Dislikes add Current User    // or remove if already in list
Likes remove Current User    // keeps only one reaction

Displaying counts and states

• To show like count: set text to Parent group's Post's Likes:count.
• To visually highlight a liked button: condition When Current User is in Post's Likes.

This method is beginner‑friendly, works with Bubble privacy rules, and scales well for normal app usage.
