Question

我需要有上传文件的网络表单。我希望用原始名称保存上传的文件。

我有这个PHP代码：

<form action="" enctype="multipart/form-data" method="POST">
  <input type="file" name="file" /> <br />
  <input type="submit" value="Upload" />
</form>

<?php
  if ( ($_SERVER['REQUEST_METHOD'] == 'POST') ) {
    $fieldname = $_REQUEST['file'];
    $tmpfile = $_FILES[$fieldname]['tmp_name'];

    $info = pathinfo($tmpfile);
    $filename = 'newfile.' . $info['extension'];

    $uploaddir = 'uploads/';
    $uploadfile = $uploaddir . $filename;

    if(move_uploaded_file($tmpfile, $uploadfile)) {
      echo $uploadfile;
    }

  }
?>

但在用户上传文件后，我在服务器上有tmp_name个文件。

我需要的是：用户上传文件photo123.jpg - 我希望服务器上有photo123.jpg。用户上传firefox.exe - 我想要firefox.exe

Answer 1

试试这个：

$fieldname = $_FILES['file']['name'];

而不是$fieldname = $_REQUEST['file'];

Answer 2

尝试使用$_FILES['file']['name']

if ( ($_SERVER['REQUEST_METHOD'] == 'POST') ) {
    $tmpfile = $_FILES['file']['tmp_name'];
    $filename = $_FILES['file']['name'];
    $uploaddir = 'uploads/';
    $uploadfile = $uploaddir . $filename;
    if(move_uploaded_file($tmpfile, $uploadfile)) {
      echo $uploadfile;
    }
  }

上传文件并以原始名称保存
