Php file upload always empty

Question

Always when I upload a file the result is empty. The code is from here.

The index.html file:

<html>
<body>

<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>

The upload_file.php:

<?php
  echo "Upload: " . $_FILES['file']['name'] . "<br>";
?>

The result is:

Upload:

I configure my php.ini, too enable file_upload, memory 5000M, and tmp location.

I don't know it maters but I use Ubuntu.

The result of phpinfo is as I configure.

What's wrong? Thanks!

print_r is show Array ()

echo $_FILES['userfile']['error'];

At my original file error log is empty.

Have you tried restarting Apache after changing your php.ini settings? — fire

Show us the ouput of print_r($_FILES); like @OneOfOne suggested. — Tobias Golbs

If that is your entire code, you are missing move_uploaded_file() <= do read the manual. @user3369031 - Amongst other things. That single line of code won't upload anything. If it isn't your full code, then do post it. — Funk Forty Niner

"Always when I upload a file the result is empty. The code is from here."

The code you say that you took from W3Schools is not what you posted for code and that you mention the code you are using is only:

<?php
  echo "Upload: " . $_FILES['file']['name'] . "<br>";
?>

What W3Schools has on their page (from the link you provided), is the following:

HTML form:

<html>
<body>

<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>

PHP

<?php
if ($_FILES["file"]["error"] > 0)
  {
  echo "Error: " . $_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 "Stored in: " . $_FILES["file"]["tmp_name"];
  }
?>

Yet this is missing the most important component move_uploaded_file()

which is included further down the page under Saving the Uploaded File and is as follows: (assuming you want to only allow ("gif", "jpeg", "jpg", "png") in the array.

<?php
$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/x-png")
|| ($_FILES["file"]["type"] == "image/png"))
&& ($_FILES["file"]["size"] < 20000)
&& in_array($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";
  }
?>

Now, you need to create a folder called upload and then run the form and PHP from your root and make sure that the folder exists and has proper write permissions.

Invalid file all the time. move_uploaded_file() is change the file location not modify the output of $_FILES['file']['name'] witch is null. In the tmp folder is nothing.

Funk Forty Niner Over a year ago

Are you running the form and have the PHP in the root (and not in a sub-folder), and does the upload folder exist with proper write permissions? @user3369031 and did you copy everything exactly from my answer?

user3369031 Over a year ago

All yes. I triple checked everything befoure open this topic.

Funk Forty Niner Over a year ago

I remember seeing another question a week or so ago, about a similar problem where the OP was running it from Ubuntu server and had to change the folder permissions elsewhere and I can't remember what it was exactly. It's most likely the same thing happening. @user3369031

user3369031 Over a year ago

That ask was not on stackoverflow. I fix it and i started another project. It was not a bit asame i had a ftp that deny me to have 777 at /var/www/.

Your code is fine. The problem must be with configuration on your server. Check this lines in php.ini:

file_uploads, upload_max_filesize, upload_tmp_dir, post_max_size, max_input_time

You can also echo this line:

$_FILES['userfile']['error']

As in your list: on, 5000M, /var/www/test/tmp, 8M, 60. And the code is return nothing.

sunshinejr Over a year ago

You just copied $_FILES['userfile']['error'] or used $_FILES['file']['error'] also, did you checked error logs?

user3369031 Over a year ago

Both, and both return null. On error logs have lots but i dont know what they mean. Posted up.
