How to Filter PHP Tables Using JavaScript with Multiple Search Inputs

Filtering data in a dynamic web application can greatly enhance user experience. However, if you're faced with the challenge of filtering a PHP-generated table based on multiple inputs (like department and role), it can become a bit tricky. In this guide, we will guide you through the problem and provide step-by-step instructions to implement efficient filtering using pure JavaScript.

Understanding the Problem

Imagine you have a table displayed on your webpage that is populated with data from your database. In your setup, you want users to be able to filter this table based on two criteria:

Department (dept): e.g., marketing

Role: e.g., team lead

Current Limitation

Within your existing code, you're only able to filter by a single input at a time. This means if a user inputs "marketing" in one search field and "team lead" in another, they can only see results filtered by either "marketing" OR "team lead". Ideally, they should see results that match both criteria.

Solution Breakdown

To achieve filtering based on multiple search inputs, we need to restructure our JavaScript code. We'll walk you through the necessary changes.

1. Modify the Script for Multiple Inputs

Your current script is fetching only one search value at a time. We will need to aggregate values from multiple inputs and search through them simultaneously.

Revised JavaScript Code

2. Explanation of Changes

Collect multiple values: We retrieve all the values from fields with the class search and convert them to lowercase for case insensitivity.

Matching logic: Instead of checking if the row contains just one search term, we check that all search terms provided by the user are present in the row. This is achieved using the every method which ensures every condition is met.

3. Implementing in Your HTML

Make sure your HTML includes relevant input fields for filtering:

Conclusion

By following the above steps, you can successfully filter a PHP table by multiple search inputs without the need for jQuery. This approach not only improves usability but also ensures that users can find exactly what they are looking for with more precision.

Implement this solution and enjoy enhanced functionality in your web applications!
