What are some best practices for using option boxes in PHP forms to redirect to specific pages based on user selection?

When using option boxes in PHP forms to redirect to specific pages based on user selection, it is important to use the "onchange" event in JavaScript to trigger the redirection. This event allows the page to redirect immediately after the user makes a selection without needing to submit the form. Additionally, ensure that the option values correspond to the URLs of the pages to redirect to.

<form action="" method="post">
    <select id="redirectSelect" onchange="window.location.href = this.value;">
        <option value="">Select a page to redirect</option>
        <option value="page1.php">Page 1</option>
        <option value="page2.php">Page 2</option>
        <option value="page3.php">Page 3</option>
    </select>
</form>
