Question

我创建了这个登录系统，它一直工作到今天下午突然没有$结果，因此代码不起作用。我检查了我的数据库和de查询是正确的但不知何故我的代码没有做任何事情。 $ _POST语句给出了正确的值，并且在注册后第一次脚本有效，但之后它就注定了。

if (!empty($_POST['email'])) {
include("connectdb.php");

$success = false;

$stmt = $db->prepare("SELECT 1 FROM users WHERE email=? AND password=sha1(?)");

$stmt2 = $db->prepare("SELECT klantnummer FROM users WHERE email = ? AND password =sha1(?)");
$stmt->bindValue(1, $_POST["email"], PDO::PARAM_STR);
$stmt->bindValue(2, $_POST["password"], PDO::PARAM_STR);
$stmt2->bindValue(1, $_POST["email"], PDO::PARAM_STR);
$stmt2->bindValue(2, $_POST["password"], PDO::PARAM_STR);
$stmt->execute();
$stmt2->execute();
$result = $stmt->fetch(PDO::FETCH_NUM);
echo $result;
if ($result) {

  if ($result[0] === "1"){
    $success = true;
}}
else {echo "very wrong";}
while($row = $stmt2->fetch(PDO::FETCH_ASSOC)){
     $userid= $row['klantnummer'];

     $naam = $row['voornaam'] ." ". $row['achternaam']; 
     }  
if ($success){

$_SESSION['loggedin'] = true;
$_SESSION['userid'] = $userid;
$_SESSION['naam'] = $naam;


 header('Location: accountinf.php');

}  
else {
  print("Login incorrect.<br />Click <a href=\"{$_SERVER['PHP_SELF']}\">here</a> to try again.<br />");
}}
else {echo "something wrong";}

?>

<div class='login2'>
<p> Enter e-mail and password: </p>
<form action="<?php print $_SERVER['PHP_SELF']; ?>" method = "POST">
E-mail:<br>
<input type='text' name="email" required pattern="^[_a-z0-9-]+(\.[_a-z0-9-  ]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$">
<br>
Password:<br>
<input type='password' name='password' required>
<br><br>
<input type='submit' value="Submit">
</form>
<p> <a href="javascript:ReverseDisplay('lostpwbox');       javascript:HideContent('loginbox');">Forgot password?</a></p>
<p> <a href="javascript:ReverseDisplay('registerbox'); javascript:ReverseDisplay('loginbox')">If you don't have an account yet, register     here</a>.</p>
</div>

PDO登录脚本不起作用，也不会导致
