Submitting a Form with Ajax in Array Format: A Simple Guide

When you're working with web forms, handling data efficiently is crucial for building robust applications. One common requirement developers face is submitting form data using Ajax. While many might be used to sending data in a serialized format, this approach can sometimes lead to extra steps in the backend, such as using parse_str() in PHP. In this post, we will tackle how to directly submit form data in an array format using Ajax, eliminating unnecessary transformations on the server side.

The Problem: Submitting Data in Serialized Format

In traditional Ajax submissions, forms are often serialized, giving you a query string like this:

This format can complicate retrieval on the PHP side because you need to parse the string into an associative array, typically using the following method:

This additional step might feel cumbersome and can hinder the development process. You may be looking for a cleaner, more efficient way of handling form submissions without the need for further manipulation.

The Solution: Sending Data as an Array

Steps to Send Form Data in Array Format

To send your form data as an array instead of serialized, you can make a slight modification to your existing JavaScript code as follows:

Breakdown of the Method

Get the Form Element: You start by assigning your form to a variable. This gives you access to all its fields and values.

Create FormData Object: new FormData(form) takes the form element and converts its inputs into a FormData object. This object represents the form data, including files, encoded as key/value pairs.

Convert to an Object:

The Object.fromEntries() method converts the FormData object into a plain object. This is what you send to your server.

It results in a structured format that PHP can easily recognize and manipulate.

Expected Output in PHP

Upon receiving the data, your PHP code will now see the $_POST variable structured like this:

This array format is cleaner and more intuitive, allowing for simplified data manipulation.

Conclusion

Submitting form data in an array format using Ajax is not only straightforward but also eliminates additional processing steps in PHP. By utilizing the FormData object and converting it to a plain object, you can streamline your workflow. This method keeps your code clean and efficient, saving you time in your development cycles.

Whether you are building a small web application or a large-scale enterprise system, adopting this approach to form submissions can greatly enhance your overall development process. Start implementing this today and notice the reduction in complexity in your PHP data handling!
