文件上传在Heroku环境中不起作用 [英] File upload not working in Heroku environment

问题描述

我在本地开发了一个小型的网络应用程序，一切正常。部分功能允许用户上传MP3文件。本地这一切工作正常，文件被移动到正确的目录，并可以播放。在heroku中，一切似乎都起作用，除了文件不存在。

I have developed a small web app locally and all is working fine. Part of the functionality allows the user to upload MP3 files. Locally this all works fine and the files are moved to correct directory and can be played back. In heroku everything seems to work except the files aren't there.

我的代码...

标记：

<form class="form" action="../model/process-track-upload.php" method="post" enctype="multipart/form-data">
              <div class="row">
                <div class="col-xs-12 col-sm-4">
                  <div class="dashboard-widget">
                      <h3>Add a song to your collection</h3>
                      <input class="input" type="text" name="trackname" placeholder="Track Name" required/>
                      <input class="input-margin" type="file" name="pic" />
                      <input type="hidden" name="userID" value="<?php echo $userID ?>" />
                      <button class="btn btn-large btn-block " type="submit" name="btn-upload">upload</button>
                  </div>
                </div>
              </form>

PHP：

PHP:

if(isset($_POST['btn-upload']))
{
        $pic = rand(100,1000000)."-".$_FILES['pic']['name'];
        $pic_loc = $_FILES['pic']['tmp_name'];
        $folder="../tracks/uploads/";
        if(move_uploaded_file($pic_loc,$folder.$pic))
        {
            ?><script>alert('successfully uploaded');</script><?php
        }
        else
        {
            ?><script>alert('error while uploading file');</script><?php
}
}

我不太喜欢使用环境配置等等，在这里。

I'm not awesome with environment configuration etc so it may be something going on there.

我应该添加作为一个笔记，当我推到Heroku我本地添加的文件是可用的。这只是我添加的文件，使用基于Heroku的版本的应用程序，而不是保存在正确的（或任何）目录。

I should add as a note that files I added locally are available when I push to Heroku. It's only files that I add using the Heroku based version of the app that aren't getting saved in the correct (or any) directory.

谢谢
