How can the issue of inserting empty data records be addressed in PHP and MySQL scripts?

Issue: To address the problem of inserting empty data records in PHP and MySQL scripts, we can add validation checks to ensure that the data being inserted is not empty. This can be done by checking the input data before executing the SQL query to insert the records into the database. 

// Validate input data before inserting into the database
if (!empty($data['field1']) && !empty($data['field2'])) {
    // Connect to MySQL database
    $conn = new mysqli($servername, $username, $password, $dbname);

    // Check connection
    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    }

    // Prepare SQL query to insert data into database
    $sql = "INSERT INTO table_name (field1, field2) VALUES ('".$data['field1']."', '".$data['field2']."')";

    // Execute SQL query
    if ($conn->query($sql) === TRUE) {
        echo "Record inserted successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }

    // Close database connection
    $conn->close();
} else {
    echo "Error: Input data cannot be empty";
}
