title: Why won't my file upload with my PHP upload script?
body: <p>First I asked this question here: <a href="https://stackoverflow.com/questions/19921070/how-do-i-change-the-file-name-before-sending-to-upload-file-php">How do I change the file name before sending to upload_file.php?</a></p>
  
  <p>I updated my upload_file.php script with the suggestion, but when I run it, it doesn't work. Using the form from the above link, when I go to upload the script, the echo's seem correct, but when I FTP to the directory the file is supposed to be, the directory is empty? Could someone shine some light on this? I want the file to be uploaded to '/var/www/eedis/fax/uploads/'.</p>
  
  <p>My upload_file.php script looks like this...</p>
  
  <pre><code>&lt;?php
  $allowedExts = array("pdf");
  $temp = explode(".", $_FILES["file"]["name"]);
  $extension = end($temp);
  if ($_FILES["file"]["type"] == "application/pdf")
  #&amp;&amp; ($_FILES["file"]["size"] &lt; 20000)
  #&amp;&amp; in_array($extension, $allowedExts))
    {
    if ($_FILES["file"]["error"] &gt; 0)
      {
      echo "Return Code: " . $_FILES["file"]["error"] . "&lt;br&gt;";
      }
    else
      {
      echo "Upload: " . $_FILES["file"]["name"] . "&lt;br&gt;";
      echo "Type: " . $_FILES["file"]["type"] . "&lt;br&gt;";
      echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB&lt;br&gt;";
  
      if (file_exists("upload/" . $_FILES["file"]["name"]))
        {
        echo $_FILES["file"]["name"] . " already exists. ";
        }
      else
        {
        move_uploaded_file($_FILES["file"]["tmp_name"],
        "/var/www/eedis/fax/uploads/" . $_POST['number'] . '.pdf');
        }
      }
    }
  else
    {
    echo "Invalid file";
    }
  ?&gt; 
  </code></pre>
