尝试在我的网页上注册用户时出现以下错误:
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
^ 指向带有注册脚本的 PHP 文件
并且指向以下脚本的内部服务器错误:
$("#login-submit").on('click', function () {
$.ajax({
url: 'ext/login_process.php',
type: "POST",
data: $("#login-form").serialize(),
success: function (result) {
if (result === "done") {
window.location.href = "index.php";
} else {
var elementExists = document.getElementById("msg-default");
if (elementExists !== null) {
document.getElementById("msg-default").innerHTML = "";
}
document.getElementById("err-msg").innerHTML = "<div class = 'alert alert-danger text-uppercase'><strong>Error! </strong>" + result + "</div></div>";
}
},
error: function (xhr, resp, text) {
console.log(xhr, resp, text);
}
});
});
错误发生在按下注册按钮时。如果用户名已被使用，它会正常工作，然后该消息将按应有的方式显示。
HTML:
<form name="register-form" id="register-form" method="POST">
<h5 class="text-center">Register</h5>
<div class="form-group">
<input type="text" class="form-control" placeholder="Username" name="username" required>
</div>
<div class="form-group">
<input type="password" class="form-control" placeholder="Password" name="password" required>
</div>
<div class="form-group">
<input type="password" class="form-control" placeholder="Repeat password" name="c-password" required>
</div>
<div class="form-group">
<label>I am...</label>
<div class="radio">
<label><input type="radio" name="position" checked value="s"> Student</label>
</div>
<div class="radio">
<label><input type="radio" name="position" value="t"> Teacher</label>
</div>
</div>
<div class="err-msg" id="err-msg"></div>
</form>
<button id="register-submit" class="btn btn-success">Senda</button>
PHP:
$username = trim(preg_replace('/\s+/', ' ', htmlspecialchars($_POST["username"])));
$password = htmlspecialchars($_POST["password"]); // Do not trim the password, let the user input whatever they desire
$confirmPssword = htmlspecialchars($_POST["c-password"]); // Do not trim the password, let the user input whatever they desire
$position = trim(preg_replace('/\s+/', ' ', htmlspecialchars($_POST["position"])));
if (empty($username))
{
echo "Invalid username!";
} else
if (empty($password))
{
echo "Invalid password!";
} else
if ($confirmPssword != $password)
{
echo "Password/Confirm Password didn't match!";
} else {
$sql = get_user_details($username);
$result = $conn->query($sql);
if ($result)
{
if ($result->num_rows > 0)
{
$result->close();
echo "username is already registered";
} else {
// Generate a new random salt
$salt = '$1$' . substr(strtr(base64_encode(random_bytes(32)), '+', '.'), 0, 8) . '$';
// Generate the MD5 hashed password
$cryptedPassword = crypt($password, $salt);
$sql = add_user($username, $cryptedPassword, $position);
if ($conn->query($sql))
{
echo "done";
} else {
echo "please refresh the page and try again";
}
}
} else {
echo "please refresh the page and try again";
}
$conn->close();
}
我正在使用这个:https://code.jquery.com/jquery-3.1.1.min.js
我在哪里可以获得有关 cpanel 错误的更多具体信息？
