我正在尝试执行以下代码，但我一直收到以下错误:
"Could not execute the insert query."
似乎插入 Employees 不工作。
我不确定缺少什么。
下面是我的代码:
if(isset($_POST['submit'])) {
$fname = $_POST['fname'];
$minitial = $_POST['minitial'];
$lname = $_POST['lname'];
$gender = $_POST['gender'];
$phone = $_POST['phone'];
$dob = $_POST['dob'];
$ssn = $_POST['ssn'];
$address = $_POST['address'];
$city = $_POST['city'];
$state = $_POST['state'];
$zip = $_POST['zip'];
$email = $_POST['email'];
$username = $_POST['username'];
$password = $_POST['password'];
if($fname == "" || $minitial == "" || $lname == "" || $gender == "" ||
$phone == "" || $dob == "" || $ssn == "" || $address == "" ||
$city == "" || $state == "" || $zip == "" || $email == "" ||
$username == "" || $password == "") {
echo "All fields should be filled. Either one or many fields are empty.";
echo "<br/>";
echo "<a href='register.php'>Go back</a>";}
else {
mysqli_query($mysqli, "INSERT INTO 'Employees'('fname', 'minitial', 'lname', 'gender', 'phone', 'dob', 'ssn', 'address', 'city', 'state', 'zip', 'email', 'username', 'password') VALUES('$fname', '$minitial', '$lname', '$gender', '$phone', '$dob', '$ssn', '$address', '$city', '$state', '$zip', '$email', '$username', md5('$password'))")
or die("Could not execute the insert query.");
echo "Registration successfully";
echo "<br/>";
echo "<a href='login.php'>Login</a>";
}
