<?
if(isset($_POST['submit'])){

$url = 'http://www.connectedcampus.org/ckeditor/images/uploads/';

if (($_FILES['upload'] == "none") OR (empty($_FILES['upload']['name'])) )
{
   $message = "No file uploaded.";

else if ($_FILES['upload']["size"] == 0)
{
   $message = "The file is of zero length.";
}
else if (($_FILES['upload']["type"] != "image/pjpeg") AND ($_FILES['upload']["type"] != "image/jpeg") AND ($_FILES['upload']["type"] != "image/png"))
{
   $message = "The image must be in either JPG or PNG format. Please upload a JPG or PNG instead.";
}
else if($_FILES["file"]["size"] > 1000000){
    $message = "File size too big!";
}
else if(file_exists($url.$_FILES["file"]["name"]))
  {
  $message=$_FILES["file"]["name"] . " already exists. ";
  }
else if (!is_uploaded_file($_FILES['upload']["tmp_name"]))
{
   $message = "Invalid File!";
}
else {
  $message = "success!";
  $move = move_uploaded_file($_FILES['upload']['tmp_name'], $url.$_FILES['upload']['name']);
  echo $_FILES['upload']['tmp_name']."<br>";
  echo $url.$_FILES['upload']['name'];
  if(!$move)

     $message = "Error moving uploaded file.";
  }

 echo $message;
 </script>";
 }

打印“移动上传文件时出错” 这意味着move_uploaded_file（$ _ FILES ['upload'] ['tmp_name']，$ url。$ _ FILES ['upload'] ['name']）返回false。但我500％确定我已正确创建http://www.connectedcampus.org/ckeditor/images/uploads/文件夹....那么为什么会出错？

好的，现在改为：

$url = 'bloguploads/';

    if (($_FILES['upload'] == "none") OR (empty($_FILES['upload']['name'])) )
    {
       $message = "No file uploaded.";
    }
    else if ($_FILES['upload']["size"] == 0)
    {
       $message = "The file is of zero length.";
    }
    else if (($_FILES['upload']["type"] != "image/pjpeg") AND ($_FILES['upload']["type"] != "image/jpeg") AND ($_FILES['upload']["type"] != "image/png"))
    {
       $message = "The image must be in either JPG or PNG format. Please upload a JPG or PNG instead.";
    }
else if($_FILES["file"]["size"] > 1000000){
       $message = "File size too big!";
}
else if(file_exists($url.$_FILES["file"]["name"]))
    {
       $message=$_FILES["file"]["name"] . " already exists. ";
    }
    else if (!is_uploaded_file($_FILES['upload']["tmp_name"]))
    {
       $message = "Invalid File!";
    }
    else {
       $message = "";
       $move = move_uploaded_file($_FILES['upload']['tmp_name'], $url.$_FILES['upload']['name']);
       if(!$move)
       {
           $message = "Error moving uploaded file.";
       }
       $url = $url.$_FILES['upload']['name'];
       }
echo $message;
</script>";
?>

现在的事情是，它说“已经存在”。为什么？我可以通过ftp客户端看到该文件尚未上传

Answer 1

move_uploaded_file适用于文件系统，而不适用于网址。

而不是

中的$url

move_uploaded_file($_FILES['upload']['tmp_name'], $url.$_FILES['upload']['name']);

使用文件系统路径，即：

move_uploaded_file($_FILES['upload']['tmp_name'], "/home/www/uploads/".$_FILES['upload']['name']);
