How can PHP developers troubleshoot and resolve issues related to form validation and redirection when using buttons and links in combination?

Issue: When using buttons and links in combination for form submission and redirection, PHP developers may encounter issues with form validation not working properly or redirection not happening as expected. To troubleshoot and resolve these issues, developers can ensure that form validation checks are properly implemented before redirection is triggered, and use appropriate conditional statements to handle different scenarios based on the form submission method. 

<?php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Perform form validation checks
    // If validation passes, redirect to a new page
    if (/* validation condition */) {
        header("Location: newpage.php");
        exit;
    } else {
        // Handle validation errors
    }
}
?>

<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>">
    <!-- Form fields -->
    
    <button type="submit" name="submit">Submit</button>
    <a href="newpage.php">Go to new page</a>
</form>
