How to Filter a GridView Table in Yii2 Without Affecting Others

If you're working with Yii2 and want to filter specific data in a GridView without affecting other tables, you're in the right place! This challenge might arise when you need one table to display a subset of data (for example, only entries with id = 2), while keeping another table intact with all entries. The solution lies in utilizing multiple DataProviders within your Yii2 application. Let’s dive into how you can achieve this efficiently.

The Problem

You have two GridView tables in your Yii2 application:

Table One: Displays all available data.

Table Two: Required to display only entries where id = 2.

The dilemma arises when you try to implement filtering through a single search model, which impacts both tables. However, there’s a clean solution by creating isolated DataProviders for each GridView instance.

The Solution: Using Two DataProviders

To successfully implement separate filters for each table, you need to create two distinct DataProviders. Here’s a step-by-step breakdown of what you need to do:

Step 1: Create the Search Models

You will instantiate two instances of the JobPlanningSearch class. This allows each instance to maintain its own state and filtering rules. Here's how you can do it:

Step 2: Render Each GridView

After you have created both DataProviders, your next task is to render each GridView accordingly within your view file. You can do this by specifying the respective DataProvider for each GridView:

Step 3: Customize Pagination and Filtering

With the implementation of multiple DataProviders, you'll want to ensure that each table has its unique pagination and filtering settings. The example provided demonstrates how to adjust the page parameters. Make sure to test each GridView independently to verify that they exhibit the desired behavior:

Table One: Should show all records.

Table Two: Should only show records where id = 2.

Conclusion

By employing two separate DataProviders, you can effectively control the filtering for each GridView in Yii2 without any conflicts. This approach not only streamlines your data display but also enhances user experience by allowing targeted data interaction.

Feel free to implement these steps in your projects, and watch as your GridView tables become more efficient and tailored to user needs!
