Are there any potential pitfalls when using jQuery Mobile with PHP and MySQL?
One potential pitfall when using jQuery Mobile with PHP and MySQL is the risk of SQL injection attacks if user input is not properly sanitized before being used in database queries. To prevent this, always use prepared statements or parameterized queries when interacting with the database.
// Example of using prepared statements to prevent SQL injection
$mysqli = new mysqli("localhost", "username", "password", "database");
// Check connection
if ($mysqli->connect_error) {
die("Connection failed: " . $mysqli->connect_error);
}
// Prepare a SQL statement
$stmt = $mysqli->prepare("SELECT * FROM users WHERE username = ?");
$stmt->bind_param("s", $username);
// Set parameters and execute
$username = $_POST['username'];
$stmt->execute();
// Get the result
$result = $stmt->get_result();
// Fetch data
while ($row = $result->fetch_assoc()) {
// Do something with the data
}
// Close statement and connection
$stmt->close();
$mysqli->close();
