Question

I copied the code from this page:
http://www.w3schools.com/php/php_file_upload.asp

Problem is that i don’t get an error when uploading a file, instead this
shows which should be correct:

Upload: images.jpeg
Type: image/jpeg
Size: 5.8603515625 kB
Temp file: /tmp/phpZ67YXk
Stored in: upload/images.jpeg

But no file is saved on the server.

I don’t know what is wrong but I’m thinking in terms of permission, still there is a folder
named upload with 777 permissions.

These php-files are hosted on a online web host so I don’t run this locally.

HTML-form

<form action="upload_file.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>

</body>
</html>

upload_file.php

<?php
$allowedExts = array("jpg", "jpeg", "gif", "png");
$extension = end(explode(".", $_FILES["file"]["name"]));
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000)
&& in_array($extension, $allowedExts))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br>";
    echo "Type: " . $_FILES["file"]["type"] . "<br>";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";

    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file";
  }
?>

I suppose the problem is in your relative path of destination (relative according to your current working directory = path of your .php file), try to make it absolutem like this:

move_uploaded_file(
  $_FILES["file"]["tmp_name"],
  $_SERVER['DOCUMENT_ROOT'] . 'upload/' . $_FILES["file"]["name"]
);
