Are there any potential pitfalls to using JavaScript to handle radio button group changes in PHP?

One potential pitfall of using JavaScript to handle radio button group changes in PHP is that the values may not be properly synchronized between the client-side and server-side. To solve this issue, you can use JavaScript to update a hidden input field with the selected radio button value before submitting the form to PHP. This way, PHP can access the selected value from the hidden input field.

<form method="post" action="process.php">
  <input type="radio" name="radio_group" value="option1" onclick="updateHiddenInput(this)">
  <input type="radio" name="radio_group" value="option2" onclick="updateHiddenInput(this)">
  <input type="hidden" name="selected_value" id="selected_value">
  <input type="submit" value="Submit">
</form>

<script>
function updateHiddenInput(radio) {
  document.getElementById("selected_value").value = radio.value;
}
</script>
