How can the issue of not displaying an error message when a user does not enter a new password be addressed in PHP?

Issue: The issue of not displaying an error message when a user does not enter a new password can be addressed by adding a conditional statement that checks if the new password field is empty. If it is empty, an error message should be displayed to prompt the user to enter a new password. 

if(empty($_POST['new_password'])) {
    $error_message = "Please enter a new password.";
    // Display error message to the user
    echo $error_message;
} else {
    // Proceed with updating the password
    $new_password = $_POST['new_password'];
    // Code to update the password in the database
}
