将数据插入数据库时​​出现HTTP错误500

Question

我有标题中提到的错误。当我单击表单上的提交按钮时会发生这种情况。这是我的表单句柄文件（我认为没有必要复制表单代码）：

<?php
$servername = "localhost";
  $username = "sabashel_sabaadm";
  $password = "saba1365%karaj@*";
$dbname = "sabashel_saba";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$fname = $lname = $gender = $birthdate = $organization = $degree = $field = $address = $post_code = $mobile = $email = $check_1 = $check_2 = $check_3  = $check_4  = $check_5  = $check_6  = $check_7  = $check_8 "";
$check_9 = $check_10  = $check_11  = $check_12  = $check_13 = $description = $person_image = "";



if(isset($_POST['fname']) && isset($_POST['lname']) && isset($_POST['gender']) && isset($_POST['birthdate']) && isset($_POST['degree']) && isset($_POST['filed-of-study']) && isset($_POST['address']) && isset($_POST['post-code']) && isset($_POST['mobile']) && isset($_POST['email']) && isset($_POST['check-1']) && isset($_POST['check-2']) && isset($_POST['check-3']) && isset($_POST['check-4']) && isset($_POST['check-5']) && isset($_POST['check-6']) && isset($_POST['check-7']) && isset($_POST['check-8']) && isset($_POST['check-9']) && isset($_POST['check-10']) && isset($_POST['check-11']) && isset($_POST['check-12']) && isset($_POST['check-13']) && isset($_POST['description']) && isset($_POST['person-iamge'])){
        $fname = $_POST['fname'];
        $lname = $_POST['lname'];
        $gender = $_POST['gender'];
        $birthdate = $_POST['birdthdate'];
        $organization = $_POST['organization'];
        $degree = $_POST['degree'];
        $field = $_POST['field-of-study'];
        $address = $_POST['address'];
        $post_code = $_POST['post-code'];
        $mobile = $_POST['mobile'];
        $email = $_POST['email'];
        $check_1 = $_POST['check-1'];
        $check_2 = $_POST['check-2'];
        $check_3 = $_POST['check-3'];
        $check_4 = $_POST['check-4'];
        $check_5 = $_POST['check-5'];
        $check_6 = $_POST['check-6'];
        $check_7 = $_POST['check-7'];
        $check_8 = $_POST['check-8'];
        $check_9 = $_POST['check-9'];
        $check_10 = $_POST['check-10'];
        $check_11 = $_POST['check-11'];
        $check_12 = $_POST['check-12'];
        $check_13 = $_POST['check-13'];
        $description = $_POST['description'];
        $person_image = $_POST['person-image'];
        $iftest = true;
  }
  if ($iftest == true) {
    $query = "INSERT INTO volunteer (fname, lname, gender, organization, degree, field, address, post_code, mobile, email, check_1, check_2, check_3, check_4, check_5, check_6, check_7, check_8, check_9, check_10, check_11, check_12, check_13, description, person_image, birthdate) VALUES ('$fname', '$lname', '$gender', '$organization', '$degree', '$field', '$address', '$post_code', '$mobile', '$email', '$check_1', '$check_2', '$check_3', '$check_4', '$check_5', '$check_6', '$check_7', '$check_8', '$check_9', '$check_10', '$check_11', '$check_12', '$check_13', '$description', '$person_image', '$birthdate')";
  }


  $result = mysqli_query($conn, $query);
  if ($result) {
      header('Location: http://sabashelter.com/success');
    }
    else {
      header('Location: http://sabashelter.com/fail');
    }
}


$conn->close();
?>

并且提到：我与另一个页面具有完全相同的问题，该页面执行相同的操作并尝试使用相同的代码将大量值添加到数据库中。我想知道这个页面中的问题是否解决了，同样的方法也可以用于其他页面。

正如@CBroe所说，检查您的日志文件首先。您似乎错过了第14行的=。

$fname = $lname = $gender = $birthdate = $organization = $degree = $field = $address = $post_code = $mobile = $email = $check_1 = $check_2 = $check_3  = $check_4  = $check_5  = $check_6  = $check_7  = $check_8 = "";

此外，你在第60行有一个迷路}。

您的错误日志文件将帮助您解决这些问题。
