MVC Handle multiple form submit with a single Controller Action

06 Sep 202479

Handling multiple forms on a single page in PHP can be a bit tricky if you're just getting started. In this guide, we'll break down how to manage multiple forms using PHP, along with some basic styling to make your forms look neat and professional. This tutorial is perfect for beginners who want to learn how to handle multiple form submissions in PHP while keeping their design clean and simple.

Why Handle Multiple Forms?

Sometimes, you might need to collect different types of information from users on a single page. Instead of cramming all fields into one large form, splitting them into smaller, more focused forms can make the user experience better and your code easier to manage.

Project Overview

We'll create a page with three forms, each having one input field and a submit button. The forms will be distinguished using hidden inputs, allowing us to identify which form was submitted. We'll also add basic styling using CSS to enhance the look of the forms.

Step 1: Set Up Your PHP Script

Let's start by setting up the PHP script that will handle our form submissions. We'll name this file handle_forms.php.

Here's the PHP code:

<?php
if ($_SERVER["REQUEST_METHOD"] === "POST") {
    // Check which form is submitted
    $form_type = $_POST["form_type"];

    switch ($form_type) {
        case "form1":
            $input1 = $_POST["input1"];
            echo "Form 1 Submitted with Input: " . htmlspecialchars($input1);
            break;
        case "form2":
            $input2 = $_POST["input2"];
            echo "Form 2 Submitted with Input: " . htmlspecialchars($input2);
            break;
        case "form3":
            $input3 = $_POST["input3"];
            echo "Form 3 Submitted with Input: " . htmlspecialchars($input3);
            break;
        default:
            echo "Unknown form submitted!";
            break;
    }
}
?>
