PDO准备插入语句不起作用，返回无错误

Question

我有一个用户注册脚本，它与PDO预处理语句不同，它不会将值插入数据库。 该脚本未返回错误。 MySQL用户确实拥有我正在执行的操作的权限。

Signup.php：

echo "<?xml version=\"1.0\" ?>";

if(isset($_POST['email'], $_POST['username'], $_POST['p'], $_POST['fname'], $_POST['lname'], $_POST['gender'])) {

foreach ($_POST as $entry) {
    strip_tags($entry);
}

if(strlen($_POST['email']) < 1) {
    echo "<response>Please enter an email address!</response>";
    exit();
}

if(!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
    echo "<response>Please enter a valid email address!</response>";
    exit();
}

if(strlen($_POST['p']) < 6) {
    echo "<response>Please enter a password that is longer than 6 characters!</response>";
    exit();
}

if(strlen($_POST['username']) < 5 || strlen($_POST['username']) > 30) {
    echo "<response>Please enter a username that is between 5 and 30 characters in length!</response>";
    exit();
}

if(strlen($_POST['fname']) < 1 || strlen($_POST['lname']) < 1) {
    echo "<response>Please enter a name!</response>";
    exit();
}

if(strlen($_POST['gender']) < 1) {
    echo "<response>Please select your gender!</response>";
    exit();
}

//if(strlen($_POST['recaptcha_response_field']) < 1) {
//  echo "<response>Please answer the Captcha!</response>";
//  exit();
//}

if($_POST['gender'] === "Male") {
    $_POST['gender'] = "m";
} else {
    $_POST['gender'] = "f";
}

//$recaptcha_response = null;
//$recaptcha_error = null;

//$recaptcha_response = recaptcha_check_answer($recaptcha_private_key, $_SERVER['REMOTE_ADDR'], $_POST['recaptcha_challenge_field'], $_POST['recaptcha_response_field']);

//if($recaptcha_response->is_valid) {

    $salt = hash("sha512", uniqid(mt_rand(1, mt_getrandmax()), true));
    $password = $_POST['p'];
    $password = hash("sha512", $password.$salt);

    $info = array(

        "email" => $_POST['email'],
        "password" => $password,
        "salt" => $salt,
        "username" => $_POST['username'],
        "fname" => $_POST['fname'],
        "lname" => $_POST['lname'],
        "gender" => $_POST['gender']

    );

    if(register($info, $database) === true) {

        echo "<response>Registration Successfull! Please check your inbox for an activation email!</response>";

        exit();

    }

//} else {

//  echo "<response>Incorrect Captcha! Please click the reCaptcha refresh button and try again!</response>";

//  exit();

//}

} else {

echo "<response>Invalid Sign-Up Request!</response>";

exit();

}

register（）函数：

function register($info, $database) {

try {

    $query = $database -> prepare("SELECT email FROM members WHERE email = :email LIMIT 1");

    $query -> execute(

        array(

            ":email" => $info['email']

        )

    );

    $result = $query -> fetch();
    $result = $result[1];

    if(strlen($result) > 0) {

        echo "<response>Email already in use!</response>";

        exit();

    } else {

        $query = $database -> prepare("SELECT username FROM members WHERE username = :username LIMIT 1");

        $query -> execute(

            array(

                ":username" => $info['username']

            )

        );

        $result = $query -> fetch();
        $result = $result[1];

        if(strlen($result) > 0) {

            echo "<response>Username already in use!</response>";

            exit();

        } else {

            $query = $database -> prepare("SELECT password FROM members WHERE password = :password LIMIT 1");

            $query -> execute(

                array(

                    ":password" => $info['password']

                )

            );

                $query = $database -> prepare("INSERT INTO members (email, password, salt, username, first_name, last_name, signup, last_login, gender) VALUES (:email, :password, :salt, :username, :fname, :lname, :signup, :last_login, :gender)");

                $query -> execute(

                    array(

                        ":password"    => $info['password'],
                        ":salt"               => $info['salt'],
                        ":username"  => $info['username'],
                        ":fname"          => $info['fname'],

                    )

                ) or die(print_r($query->errorInfo(), true));

                $rc = hash("sha512", uniqid(mt_rand(1, mt_getrandmax()), true));

} catch(PDOException $e) {

    echo "<response>An error occured whilst creating your account! An email has been sent to tech support!</response>";

    mail("admin@codecluster.x10.mx", "Code-Cluster Sign-Up Error", "Sign-Up Error; Timestamp @ " . date() . " ; IP Address : " . $_SERVER['REMOTE_ADDR'] . " ;\r\n" . $e);

    exit();

}

}

这是数据库结构：

Answer 1

它应该是:email，而不仅仅是数组中的email。

array(
        ":email" => $info['email']
     )

同样适用于所有其他execute()次来电。
