php - move_uploaded_file 将文件存储在哪里？

Question

我正在尝试通过网络表单上传文件。该脚本输出以下内容，并且没有错误。我仍然无法在服务器上找到目录。我指定的位置错误吗？我已经尝试过 /upload 以及在我的 ftp 客户端中看到的完整路径：/cygdrive/i/home/antor/dance/upload

   Upload: 1.jpg
    Type: image/jpeg
    Size: 107.9072265625 kB
    Stored in: C:\WINDOWS\Temp\php767.tmpUpload: 1.jpg
    Type: image/jpeg
    Size: 107.9072265625 kB
    Temp file: C:\WINDOWS\Temp\php767.tmpStored in: upload/1.jpgUpload: 1.jpg
    Type: image/jpeg
    Size: 107.9072265625 kB
    Temp file: C:\WINDOWS\Temp\php767.tmp
    Stored in: /cygdrive/i/home/antor/dance/upload/1.jpg 

这是我使用的代码：

    <form action="upload_file.php" method="post"
    enctype="multipart/form-data">
    <label for="file">Filename:</label>
    <input type="file" name="file" id="file"><br>
    <input type="submit" name="submit" value="Submit">
    </form>

和：

    <?php
    if ($_FILES["file"]["error"] > 0)
      {
      echo "Error: " . $_FILES["file"]["error"] . "<br>";
      }
    else
      {
      echo "Upload: " . $_FILES["file"]["name"] . "<br>";
      echo "Type: " . $_FILES["file"]["type"] . "<br>";
      echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
      echo "Stored in: " . $_FILES["file"]["tmp_name"];
      }
      $allowedExts = array("gif", "jpeg", "jpg", "png");
    $extension = end(explode(".", $_FILES["file"]["name"]));
    if ((($_FILES["file"]["type"] == "image/gif")
    || ($_FILES["file"]["type"] == "image/jpeg")
    || ($_FILES["file"]["type"] == "image/jpg")
    || ($_FILES["file"]["type"] == "image/pjpeg")
    || ($_FILES["file"]["type"] == "image/x-png")
    || ($_FILES["file"]["type"] == "image/png"))
    && ($_FILES["file"]["size"] < 2000000)
    && in_array($extension, $allowedExts))
      {
      if ($_FILES["file"]["error"] > 0)
        {
        echo "Error: " . $_FILES["file"]["error"] . "<br>";
        }
      else
        {
        echo "Upload: " . $_FILES["file"]["name"] . "<br>";
        echo "Type: " . $_FILES["file"]["type"] . "<br>";
        echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
        echo "Stored in: " . $_FILES["file"]["tmp_name"];
        }
      }
    else
      {
      echo "Invalid file";
      }


      $allowedExts = array("gif", "jpeg", "jpg", "png");
    $extension = end(explode(".", $_FILES["file"]["name"]));
    if ((($_FILES["file"]["type"] == "image/gif")
    || ($_FILES["file"]["type"] == "image/jpeg")
    || ($_FILES["file"]["type"] == "image/jpg")
    || ($_FILES["file"]["type"] == "image/pjpeg")
    || ($_FILES["file"]["type"] == "image/x-png")
    || ($_FILES["file"]["type"] == "image/png"))
    && ($_FILES["file"]["size"] < 2000000)
    && in_array($extension, $allowedExts))
      {
      if ($_FILES["file"]["error"] > 0)
        {
        echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
        }
      else
        {
        echo "Upload: " . $_FILES["file"]["name"] . "<br>";
        echo "Type: " . $_FILES["file"]["type"] . "<br>";
        echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
        echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";

        if (file_exists("upload/" . $_FILES["file"]["name"]))
          {
          echo $_FILES["file"]["name"] . " already exists. ";
          }
        else
          {
          move_uploaded_file($_FILES["file"]["tmp_name"],
          "upload/" . $_FILES["file"]["name"]);
          echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
          }
        }
      }
    else
      {
      echo "Invalid file";
      }

    ?> 

文件夹上传在主uploader.php文件下方，拥有777权限。知道文件存储在哪里吗？或者更好的是，我怎样才能把它放在正确的目录中。

--UPDATE update/ 文件夹似乎是正确的位置。文件仍然没有出现，我也在另一台服务器上尝试过。我在脚本中做错了吗？我可以做一些额外的错误检查吗？

.htaccess 与它有什么关系吗？在 dance 的上层有一个 drupal 站点，它有 .htaccess：

#

Answer 1

您错过了表单的 enctype 属性。将此添加到您的表单标签

enctype='multipart/form-data'

Answer 2

如果该文件夹位于 .php 文件下方，则

 move_uploaded_file($_FILES["file"]["tmp_name"],
  "upload/" . $_FILES["file"]["name"]);

正在尝试将其上传到与运行此文件的文件处于同一级别的“上传”目录。

尝试

move_uploaded_file($_FILES["file"]["tmp_name"],
  "../upload/" . $_FILES["file"]["name"]);

Answer 3

创建一个文件 info.php 并将以下内容放入其中。

<?php
phpinfo();

将其上传到您的上传脚本所在的服务器上，在浏览器中打开并找到：

_SERVER["SCRIPT_FILENAME"]

这将向您显示文件的完整路径，并有助于找出上传文件夹的路径。

正确的路径是：

move_uploaded_file($_FILES["file"]["tmp_name"], "I:\home\antor\dance\upload\\" . $_FILES["file"]["name"]);

Answer 4

假设您运行http://somelink.com/app/upload.php然后上传文件夹将仅位于 /app/upload 下

Answer 5

请务必在您的源目录或主目录中创建上传目录
