What potential pitfalls should be considered when dynamically generating HTML input fields from database values in PHP?

One potential pitfall to consider when dynamically generating HTML input fields from database values in PHP is the risk of SQL injection attacks if the database values are not properly sanitized. To mitigate this risk, always use prepared statements or parameterized queries when querying the database to ensure that user input is safely handled. 

// Example of using prepared statements to dynamically generate HTML input fields from database values
$stmt = $pdo->prepare("SELECT field_name FROM table_name WHERE condition = ?");
$stmt->execute([$condition]);

while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
    echo '<input type="text" name="' . htmlspecialchars($row['field_name']) . '">';
}
