What are the potential pitfalls of using multiple submit buttons in a PHP form for preview and submit actions?

Using multiple submit buttons in a PHP form for preview and submit actions can lead to confusion and potential errors for users. To solve this issue, you can use JavaScript to dynamically change the form action based on which button is clicked. This way, the form submission logic can be controlled more effectively. 

<form method="post" id="myForm" action="process.php">
    <!-- Form fields go here -->
    <input type="submit" name="preview" value="Preview">
    <input type="submit" name="submit" value="Submit">
</form>

<script>
    document.getElementById("myForm").addEventListener("submit", function(e) {
        var submitButton = document.activeElement;
        
        if (submitButton.name === "preview") {
            this.action = "preview.php";
        }
    });
</script>
