How can the PHP code be modified to avoid issues like cross-posting and ensure a more organized and structured approach to displaying data from a MySQL database?

To avoid issues like cross-posting and ensure a more organized approach to displaying data from a MySQL database, you can implement a check to prevent duplicate submissions and structure your code to separate database operations from presentation logic. 

<?php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Add validation and sanitization of input fields
    // Check if the post already exists in the database before inserting
    // Perform database operation to insert data
}

// Separate database operations from presentation logic
// Fetch data from the database and structure it for display
?>
