}
echo '</div>';
} else {
echo '<div class="message error">Please select at least one subject!</div>';
}
}
?>
</div>
</body>
</html>
Output
This will generate the below output ?
This code creates a multi-select drop-down form with HTML and PHP that lets users select multiple subjects and submit their choices. The selected subjects are shown on the page using PHP after submission, if no choice is selected an error message is shown. It features drop-down menus and buttons that are designed to be easy to use.
