Question

所以我尝试使用PDO来阻止sql注入，但在运行我的代码之后，数据不会输入到数据库中。如果有人能找到错误，我将非常感激。

header("location:employees.php");

$connect = mysql_connect("localhost","root","");
if(!$connect){
    die(mysql_error($connect));
}
mysql_select_db("employees",$connect) or die(mysql_error()); 
$dbConnection = new PDO('mysql:dbname=employees;host=localhost;', 'localhost', '');
$dbConnection->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$dbConnection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);


$name = $_POST['name'];
$position = $_POST['position'];
$wage = $_POST['wage'];
$preparedStatement = $db->prepare('INSERT INTO employees (name, position, wage) VALUES (:name, :position, :wage)');
$preparedStatement->execute(array(':name' => $name,':position' => $position,':wage' => $wage));
mysql_query($preparedStatement);

我没有收到任何错误或任何错误，但用户没有输入数据库。

您在这里混合概念：使用PDO或mysql_函数：

header("location:employees.php");

$dbConnection = new PDO('mysql:dbname=employees;host=localhost;', 'localhost', '');
$dbConnection->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$dbConnection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$name = $_POST['name'];
$position = $_POST['position'];
$wage = $_POST['wage'];
$preparedStatement = $db->prepare('INSERT INTO employees (name, position, wage) VALUES (:name, :position, :wage)');
$preparedStatement->execute(array(
    ':name' => $name,
    ':position' => $position,
    ':wage' => $wage
));

PHP mysql尝试使用PDO后我的查询没有运行
