What are some recommended resources for troubleshooting PHP form submission issues?

Issue: If a PHP form submission is not working as expected, it could be due to errors in the code handling the form data. This can include issues with form validation, processing the submitted data, or redirecting to the correct page after submission. To troubleshoot PHP form submission issues, it is recommended to check for any errors in the form processing code, ensure that form fields are correctly named and matched with the PHP script, and validate the input data to prevent any malicious attacks. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Validate form data
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    if (empty($name) || empty($email)) {
        echo "Please fill in all fields.";
    } else {
        // Process the form data
        // Insert data into database, send email, etc.
        
        // Redirect to a success page
        header("Location: success.php");
        exit();
    }
}
?>

<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>">
    <input type="text" name="name" placeholder="Name">
    <input type="email" name="email" placeholder="Email">
    <button type="submit">Submit</button>
</form>
