我有代码将图像上传到服务器，但用于保存图像路径到数据库的PHP代码有问题 . 它不更新数据库 . 它显示以下错误并且不能更新数据库：

( ! ) Notice: Undefined index: fileToUpload in C:\wamp\www\hosty\Uploads.php on line 4
 ( ! ) Notice: Undefined index: datereg in C:\wamp\www\hosty\Uploads.php on line 8

    <input type="file" name="image" size="50">  
<input type="Submit" name="submitted" value="Upload"
<?php
if(isset($_POST['submitted']))
{
 //connect to database
$file=$_FILES['image']['name'];
$file_tmp=$_FILES['image']['tmp_name'];

$path="your/path/".$file;
if(file_exists($path))
{
 chmod($path,0755);
  unlink($path);
}

if(move_uploaded_file($file_tmp,$path))
{
   echo "File uploaded succesfully";
   $sql = "UPDATE database ".
    "SET path = '$path'";
}  
}
?>

    希望这能解决你的问题 .

    您的查询中存在错误 .

    $query_rsUpload = "insert into infor(title,Description,userId,datereg,name,path) values('$title','$Description',,'','$datereg','$name','uploads/$name')";

    在 $Description 之后，有两个逗号 ,, .
