How to setup custom parameters in Bubble.io: Step-by-Step Guide

Setting Up Custom Parameters in Bubble.io

 

Setting up custom parameters in Bubble.io allows you to pass dynamic information between pages, users, and workflows. This guide walks you through a detailed process to implement custom parameters efficiently within your Bubble application.

 

Prerequisites

 

• An active Bubble.io account with an existing app where you intend to use custom parameters.
• Basic knowledge of Bubble’s user interface and workflow automation system.
• Understanding of URL parameters and how they can be utilized within web applications.

 

Understanding Custom Parameters in Bubble.io

 

• Custom parameters in Bubble allow you to append key-value pairs in the URL, enabling data to be sent from one page or workflow to another.
• These parameters can be used to personalize user experiences, perform conditional logic, or link related data constraints.

 

Creating Data Structure for Custom Parameters

 

• Before using custom parameters, define the data type and how it will be used in your app.
• Navigate to the Data tab and ensure the respective data type (e.g., User, Product) is structured to store or process incoming parameter data.

 

Designing the Workflow to Add Custom Parameters

 

• Identify the action or event that will lead to setting custom parameters. This could be a button click, page load, or another user interaction.
• Navigate to the Workflow tab in your Bubble editor and create or select an existing workflow that serves this action.
• Within the workflow's actions, utilize the "Go to page" action to define navigation.
• Under "Go to page," specify the target page, and use "Send more parameters" to start adding your custom parameters.
• Enter the parameter name and a dynamic value or data field that you wish to pass.

 

Accessing Custom Parameters on Target Page

 

• Once custom parameters are set, you can access them on the target page to influence design or behavior.
• Use the Bubble editor to open the target page's design or workflow setup.
• Access the parameter via "Get data from page URL" in elements or workflow actions where necessary.
• Ensure you select the correct parameter name in your dynamic expressions to fetch intended values.

 

Example: Displaying User-Specific Data Using Custom Parameters

 

• Consider an example where you need to display specific product details for a user.
• Create a "Go to page" action upon clicking the product: use parameters like `product_id` to pass the item's unique ID.
• On the target page, access the `product_id` parameter using "Get data from page URL" within data source fields of UI elements (e.g., text, images).
• Retrieve and display the correct product record by matching `product_id` with the database records.

 

Testing Custom Parameters in Your App

 

• Utilize the Bubble preview feature to test parameterized transitions and data retrieval between pages.
• Verify that the URL correctly displays intended parameters after navigation actions.
• Ensure all data fetching and display align with expectations based on parameter values in the URL.

 

Securing and Optimizing Custom Parameters

 

• Since URL parameters can be modified by users, employ checks to prevent unauthorized data access or manipulation.
• Use conditions in workflows to verify incoming parameter values before processing them.
• Consider privacy rules and constraints on server-side actions to safeguard sensitive information.

 

By following these steps, you can effectively implement custom parameters in Bubble.io, enhancing the interactivity and modularity of your application. This approach ensures data is easily transferrable and usable while maintaining application security and efficiency.
