What potential pitfalls should be considered when inserting data into a database using PHP and WordPress functions?

One potential pitfall when inserting data into a database using PHP and WordPress functions is the risk of SQL injection attacks if user input is not properly sanitized. To prevent this, always use prepared statements with parameterized queries to securely insert data into the database. 

global $wpdb;

// Sanitize user input
$user_input = sanitize_text_field( $_POST['user_input'] );

// Prepare a SQL query using a prepared statement
$wpdb->query( $wpdb->prepare( 
    "INSERT INTO wp_my_table (column_name) VALUES (%s)", 
    $user_input 
) );
