How can the PHP code be optimized to prevent errors in displaying values in Jump menus?

To prevent errors in displaying values in Jump menus, it is important to properly sanitize and validate the input data to ensure that only valid values are displayed. This can be done by using functions like htmlspecialchars() to escape special characters and prevent XSS attacks, as well as checking if the values are within a predefined list of options before displaying them in the Jump menu. 

// Sample PHP code snippet to prevent errors in displaying values in Jump menus

// Input data from user
$user_input = $_POST['jump_menu_value'];

// List of valid options for the Jump menu
$valid_options = array('Option 1', 'Option 2', 'Option 3');

// Sanitize and validate the user input
$selected_option = htmlspecialchars($user_input);
if (in_array($selected_option, $valid_options)) {
    // Display the selected option in the Jump menu
    echo '<option selected>' . $selected_option . '</option>';
} else {
    // Display a default option if the user input is not valid
    echo '<option selected>Default Option</option>';
}
