How to Save Row Values Using Checkboxes in PHP and jQuery

When working with forms in web development, you might need the ability to save specific data from a table based on user selections. A common scenario is wanting to capture details of selected rows in a table when a checkbox is checked. This blog will guide you through the process of saving those row values, such as ID, Name, Description, and Image, using PHP and jQuery.

The Problem

Imagine you have a table displaying products fetched from a JSON file through an API. Each row has a checkbox allowing users to select specific products they want to save. However, when the form is submitted, only the contents of the selected checkboxes are sent to the server, which leaves you with incomplete data. The challenge here is correctly saving the entire selected row, including its ID, Name, Description, and Image based on the checked checkbox.

Solution Overview

1. Modify the Table Structure

To capture all relevant data when a checkbox is selected, we need to ensure that the table cells containing important values have data attributes. This modification will enable us to fetch this data easily using jQuery when a checkbox is checked. The goal is to set the cells in a way that they can be easily referenced later.

3. Send Data to the Server

After collecting the row details, use AJAX to send the collected data to your PHP backend. For example:

This will send the JSON string containing the selected row’s data to your PHP script.

4. Handling Data in PHP

In your PHP file, you will need to capture the incoming data. Here's a simple PHP script to get you started:

Conclusion

Following these steps, you will be able to successfully save the values of selected rows in a table based on checkbox input using PHP and jQuery. Implementing hidden fields or employing AJAX are both efficient strategies for this purpose. This approach enhances user experience by allowing them to save pertinent information directly from a dataset without unnecessary complexity.
