我正在为一个站点编写一个登录脚本，我有大多数工作，除了在验证mysqli查询，其他tatement没有被访问，我无法弄清楚如何解决它，下面的代码是索引页面，有html，然后是调用的php脚本，除了验证所有输入字段匹配数据库字段的脚本之外，所有的php验证都有效，我可以让if语句的验证端工作并发送我到相关页面，问题是，如果if语句的第一部分中的验证显示无效，它然后传递给else语句，我得到的是一个空白的白页，它与php页面相同验证不是我需要的页面。任何帮助都将非常感激。

这是代码部分，问题是***********
$results = $mysqli->query("SELECT * FROM signed_up WHERE email = '$email'");
while($row = $results->fetch_assoc()) {
if ($row["name"] == $name && $row["email"] == $email && $row["password"] == $password) {
$regErr = 'User Already Exsists!<br>Please Login';
$_SESSION['regErr'] = $regErr;
header('location: ../login.php');
} else {
//if ($emailErr == '' && $passwordErr == '' && $password_matchErr == '' && $email_exsistErr =='') {
echo '15';
$_SESSION['emailErr'] = $emailErr;
$_SESSION['passwordErr'] = $passwordErr;
$_SESSION['confirm_passwordErr'] = $confirm_passwordErr;
$_SESSION['email_exsistErr'] = $email_exsistErr;
header('Location: ../join.php');
exit();
}
}
}
//}
?>
现在有效的编辑代码***********************
$results = $mysqli->query("SELECT * FROM signed_up WHERE email = '$email'");
while($row = $results->fetch_assoc()) {
if ($row["name"] == $name && $row["email"] == $email && $row["password"] == $password) {
$regErr = 'User Already Exsists!<br>Please Login';
$_SESSION['regErr'] = $regErr;
header('location: ../login.php');
}else{
$_SESSION['emailErr'] = $emailErr;
$_SESSION['passwordErr'] = $passwordErr;
$_SESSION['confirm_passwordErr'] = $confirm_passwordErr;
$_SESSION['email_exsistErr'] = $email_exsistErr;
header('Location: ../join.php');
exit();
}
}
}
答案 0 :(得分：0)
将验证直接放入SQL
$results = $mysqli->query("SELECT count(*) FROM signed_up WHERE email = '$email' AND name = '$name'");
if ($result->fetchColumn()){
echo "User already exists";
}else{
echo "New user";
}
