PHP文件上传不上传 [英] php file uploader not uploading

问题描述

我正在为上传视频的网站制作上传器。截至目前，它不检查它们是否是视频，只是上传它们。我通过一个简单的表单来选择一个文件并将其提交给 upload.php 。这里是我做这个的HTML：

 < form action =upload.phpmethod =postenctype =multipart / form-datatarget =upload_targetonsubmit =startUpload（）;> 
视频名称：< input type =textname =nameclass =maininputstyle =width：300px; MAXLENGTH = 80 ><峰; br> 
档案：< input name =myfiletype =fileclass =mainbutton/ style =clear：both;>< br> 
说明：< br>< / textarea>< br>< textarea cols =43rows =10> 
< input type =submitname =submitBtnvalue =Uploadclass =mainbutton/> 
< / form>< br>< br>< br> 
< p id =f1_upload_process>正在载入...< br />< img src =/ images / loader.gifwidth =20height =20/> < / p为H. 
< p id =result>< / p> 
 
< iframe id =upload_targetname =upload_targetsrc =＃style =width：0; height：0; border：0px solid #fff;> 
< script language =javascripttype =text / javascript> 
 window.top.window.stopUpload（<？php echo $ result;？>）; 
< / script> < / iframe中> 
  

以下是我的javascript函数：

  function startUpload（）{
 document.getElementById（'f1_upload_process'）。style.visibility ='visible'; 
返回true; 
} 
函数stopUpload（成功）{
 var result =''; 
 if（success == 1）{
 document.getElementById（'result'）。innerHTML = 
'< span class =msg>文件上传成功！ \ /跨度><峰; br /><峰; br />'; 
 
 else {
 document.getElementById（'result'）。innerHTML = 
'< span class =emsg>文件上传出错！ ; \ /跨度><峰; br /><峰; br />'; 
} 
 document.getElementById（'f1_upload_process'）。style.visibility ='hidden'; 
返回true; 
 
 
 
 $ b $ p 
 $ b 
最后，这里是upload.php的内容，我用它实际上传文件： 
 
 
 <？php 
 $ result = 0; 
 
 $ target_path =videos /; 
 $ target_path = $ target_path。 basename（$ _FILES ['myfile'] ['name']）; 
 $ b $ if（move_uploaded_file（$ _ FILES ['myfile'] ['tmp_name']，$ target_path））{
 $ result = 1; 
} 
 
 sleep（1）; 
？> 
  
我相信问题是用upload.php。问题不在于客户端，事实上在客户端，它上传文件，但我无法找到文件在视频文件夹，或在服务器目录中的任何文件夹。 
 
 
 
任何帮助，非常感谢。感谢！
解决方案
 这是我使用的，您可以自定义它以适应您的脚本： 
 
 
 
 只需更改*路径和*变量即可。  
 
 
 <$ 
 $ allowed_filetypes = array（'。mov'，'。mp3'，'。mp4'，'。flv'）; //这些将是通过验证的文件的类型。 
 $ max_filesize = 524288; // BYTES中的最大文件大小（目前为0.5MB）。 
 $ upload_path ='./files/'; //文件将被上传到的位置（当前是文件目录）。 
 
 $ filename = $ _FILES ['userfile'] ['name']; //获取文件的名称（包括文件扩展名）。 
 $ ext = substr（$ filename，strpos（$ filename，'。'），strlen（$ filename）-1）; //从文件名获得扩展名
 
 //检查文件类型是否被允许，如果不是DIE并通知用户。 
 if（！in_array（$ ext，$ allowed_filetypes））
 die（'您试图上传的文件是不允许的。 
 
 //现在检查文件大小，如果它太大，那么DIE并通知用户。 
 if（filesize（$ _ FILES ['userfile'] ['tmp_name']）> $ max_filesize）
 die（'您尝试上传的文件太大。 
 
 //检查是否可以上传到指定的路径，如果不是DIE并通知用户。 
 if（！is_writable（$ upload_path））
 die（'您不能上传到指定的目录，请将其改为777.'）; 
 
 //将文件上传到指定的路径。 
 if（move_uploaded_file（$ _ FILES ['userfile'] ['tmp_name']，$ upload_path。$ filename））
 echo'您的文件上传成功，查看文件< a href =' 。$ upload_path。$ filename。'title =Your File> here< / a>'; // 有效。 
 else 
 echo'文件上传时发生错误。请再试一次。'; //失败:(。

I'm making an uploader for a website which is designed to upload videos.  As of now, it doesn't check if they're videos, it's simply uploads them.  I do this through a simple form that selects a file and submits it to upload.php.  Here is the HTML which I do this with:
<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>
Here are my javascript functions which accompany this:
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;   
}
And finally, here is the contents of upload.php, which I use for actually uploading the file:
<?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);
?>
I believe that the issue is with the upload.php.  The problem is not with anything client side, it's the fact that in the client, it uploads the file, but I can't find the file in the videos folder, or any folder in the server directory.  


Any help is greatly appreciated.  Thanks!
解决方案
This is what I use, you can customize it to suit your script:

Simply change the *path and *variables.
<?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 :(.

?>
