How can the issue of data appearing as NULL in the database be resolved when using PHP for form submissions?

Issue: The problem of data appearing as NULL in the database when using PHP for form submissions can be resolved by ensuring that the form fields are properly named and that the data is being correctly passed to the database query. PHP Code Snippet: 

// Assuming form fields are named 'name' and 'email'
$name = isset($_POST['name']) ? $_POST['name'] : '';
$email = isset($_POST['email']) ? $_POST['email'] : '';

// Check if the form fields are not empty before inserting into the database
if(!empty($name) && !empty($email)) {
    // Insert data into the database
    $query = "INSERT INTO users (name, email) VALUES ('$name', '$email')";
    // Execute the query
    $result = mysqli_query($connection, $query);
    
    if($result) {
        echo "Data inserted successfully!";
    } else {
        echo "Error: " . mysqli_error($connection);
    }
} else {
    echo "Please fill out all the form fields.";
}
