How can the issue of not being able to read the form data of the radio button be resolved in a PHP webshop application?

Issue: The problem of not being able to read the form data of the radio button in a PHP webshop application can be resolved by ensuring that the radio button input fields have a unique "name" attribute. This allows PHP to properly read the selected value from the form submission. PHP Code Snippet: 

<form method="post">
    <input type="radio" name="color" value="red"> Red
    <input type="radio" name="color" value="blue"> Blue
    <input type="radio" name="color" value="green"> Green
    <input type="submit" name="submit" value="Submit">
</form>

<?php
if(isset($_POST['submit'])) {
    $selectedColor = $_POST['color'];
    echo "Selected color: " . $selectedColor;
}
?>
