这里我的错误是什么？我应该在哪里修复我的编码

Question

我在这里得到了mysqli_error（）。我希望有人会帮助我。我一直想着这3天。

这是我的php代码

<?php
$conn=new PDO('mysql:host=xxx; dbname=xxx', 'xxxx', '') or die(mysql_error());
if(isset($_POST['submit'])!=""){


    $title = $_POST['title'];// file title
    $date = $_POST['date'];// file date
    $ref = $_POST['ref'];// file ref
    $from_to = $_POST['from_to'];// person incharge
    $details = $_POST['details'];// details
    $location = $_POST['location'];// file location
    $status = $_POST['status'];// file status   

  $name=$_FILES['photo']['name'];
  $size=$_FILES['photo']['size'];
  $type=$_FILES['photo']['type'];
  $temp=$_FILES['photo']['tmp_name'];
  move_uploaded_file($temp,"upload/".$name);
$query=$conn->query("INSERT INTO upload(title, date, ref, from_to, details, location, status, name)VALUES('$title', '$date', '$ref', '$from_to', '$details', '$location', '$status', $name)");
if($query){
header("location:index.php");
    }
else{
die(mysqli_error());
    }
}
?>

你最后在名字旁边遗漏了一些引号......

$query=$conn->query("INSERT INTO upload(title, date, ref, from_to, details, location, status, name)VALUES('$title', '$date', '$ref', '$from_to', '$details', '$location', '$status', '$name')");

虽然您应该将其更改为使用预准备语句。
