我有一個用戶註冊腳本，它除PDO準備語句之外的所有工作都不會將值插入到數據庫中。 腳本沒有返回錯誤。 MySQL用戶確實擁有我正在執行的操作的權限。PDO準備好的插入語句不起作用，返回無錯誤
的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, $database) === true) {
echo "<response>Registration Successfull! Please check your inbox for an activation email!</response>";
exit();
}
//} else {
// echo "<response>Incorrect Captcha! Please click the reCaptcha refresh button and try again!</response>";
// exit();
//}
} else {
echo "<response>Invalid Sign-Up Request!</response>";
exit();
}
寄存器（）函數：
function register($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();

if(strlen($result) > 0) {

exit();

$query -> execute(

這是數據庫結構： 
**哪些**準備好的語句不起作用？快速掃描可以看到至少5個。 – 2013-02-19 03:52:46
'插入'語句。標題中提供了這一點。我不確定'Select'語句是否工作，因爲數據庫中沒有條目。我正嘗試使用註冊腳本添加到數據庫中。 – 2013-02-19 03:56:12
在問題中似乎存在太多的代碼而不是問題所要求的。請追蹤某些錯誤的地方併發布特定的代碼，不要再多出5-10行。刪除空行也將不勝感激。謝謝。 – 2013-02-19 14:39:08
