How to Delete Rows from a Table Using Bootstrap Modal in CodeIgniter

When working with CodeIgniter, handling data within modals can sometimes lead to confusion, especially when it comes to deleting rows from a database table. In this post, we'll address a common scenario where developers need to remove items from a product table using Bootstrap modals, while ensuring that their code adheres to good practices.

Understanding the Problem

Imagine you have a table displaying products in your web application, and you want to provide users with the ability to delete these products via a Bootstrap modal. The challenge is to get the correct data from the database to ensure that the intended product is removed when the user confirms the deletion action.

What We Need

To successfully delete a product using a modal, we need to ensure:

A function in our controller that will handle deletion.

A corresponding function in our model to execute the deletion.

Proper AJAX setup in our view to make the call without refreshing the page.

Step-by-Step Solution

Step 1: Creating the Model Function

First, you'll need to add a function in your model to handle the deletion of a product. Here’s an example code snippet that demonstrates this:

This function uses the query builder to delete a row from the product_tbl based on the unique product_id.

Step 2: Updating Your Controller

Next, you need to add a method in your controller that will be called using AJAX when a user confirms the deletion in the modal. Here’s how you might set that up:

This method will respond to an AJAX call and will return a status based on whether the deletion was successful or not.

Step 3: Setting Up AJAX in Your View

Now that you have the backend ready, let’s set up the frontend to handle the modal and the AJAX call. Make sure your Remove button in the table calls the modal with the correct product ID.

Modify the Remove Button

Change your Remove button to include the data- attribute for the product ID:

Create the Modal and AJAX Script

Inside your modal, you will need a confirmation button that triggers the deletion. Add this script to handle the AJAX call:

Conclusion

By following the steps outlined above, you can effectively allow users to delete products from a database using Bootstrap modals in CodeIgniter. Ensure that you handle permissions and validate user actions appropriately to maintain the integrity of your application.

Remember to test thoroughly to confirm that all functionality works as expected. Happy coding!
