Question

我正在为一个旨在上传视频的网站制作一个上传器。截至目前，它不会检查它们是否是视频，只是上传它们。我通过一个选择文件并将其提交到upload.php的简单表单来完成此操作。这是我用它做的HTML：

<form action="upload.php" method="post" enctype="multipart/form-data" target="upload_target" onsubmit="startUpload();">
Video Name: <input type="text" name="name" class="maininput" style="width:300px;" maxlength="80"><br>
File: <input name="myfile" type="file" class="mainbutton"/ style="clear:both;"><br>
Description: <br><textarea cols="43" rows="10"></textarea><br>
      <input type="submit" name="submitBtn" value="Upload" class="mainbutton"/>
</form><br><br><br>
<p id="f1_upload_process">Loading...<br/><img src="/images/loader.gif" width="20" height="20" /></p>
<p id="result"></p>

<iframe id="upload_target" name="upload_target" src="#" style="width:0;height:0;border:0px solid #fff;">
<script language="javascript" type="text/javascript">
window.top.window.stopUpload(<?php echo $result; ?>);
</script> </iframe>

以下是我的javascript函数：

function startUpload(){
    document.getElementById('f1_upload_process').style.visibility = 'visible';
    return true;
}
function stopUpload(success){
      var result = '';
      if (success == 1){
         document.getElementById('result').innerHTML =
       '<span class="msg">The file was uploaded successfully!<\/span><br/><br/>';
      }
      else {
         document.getElementById('result').innerHTML = 
           '<span class="emsg">There was an error during file upload!<\/span><br/><br/>';
      }
      document.getElementById('f1_upload_process').style.visibility = 'hidden';
      return true;   
}

最后，这是upload.php的内容，我用它来实际上传文件：

<?php
   $result = 0;

   $target_path = "videos/";
   $target_path = $target_path . basename( $_FILES['myfile']['name']); 

    if(move_uploaded_file($_FILES['myfile']['tmp_name'], $target_path)) {
      $result = 1;
    }

   sleep(1);
?>

我认为问题在于upload.php。问题不在于客户端，事实是在客户端，它上传文件，但我找不到视频文件夹中的文件，或服务器目录中的任何文件夹。

非常感谢任何帮助。谢谢！

这是我使用的，您可以自定义它以适合您的脚本：

只需更改*路径和*变量。

<?php
// Configuration - Your Options
$allowed_filetypes = array('.mov','.mp3','.mp4','.flv'); // These will be the types of file that will pass the validation.
$max_filesize = 524288; // Maximum filesize in BYTES (currently 0.5MB).
$upload_path = './files/'; // The place the files will be uploaded to (currently a 'files' directory).

$filename = $_FILES['userfile']['name']; // Get the name of the file (including file extension).
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); // Get the extension from the filename.

// Check if the filetype is allowed, if not DIE and inform the user.
if(!in_array($ext,$allowed_filetypes))
die('The file you attempted to upload is not allowed.');

// Now check the filesize, if it is too large then DIE and inform the user.
if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
die('The file you attempted to upload is too large.');

// Check if we can upload to the specified path, if not DIE and inform the user.
if(!is_writable($upload_path))
die('You cannot upload to the specified directory, please CHMOD it to 777.');

// Upload the file to your specified path.
if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename))
echo 'Your file upload was successful, view the file <a href="' . $upload_path . $filename . '" title="Your File">here</a>'; // It worked.
else
echo 'There was an error during the file upload. Please try again.'; // It failed :(.

?>
