I need to upload file on server from command line. I do next:

wget -d --post-file=links.txt

Here is upload_file.php . Code below doesn't work of course:

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"];

  "upload/" . $_FILES["file"]["name"]);
  echo "Stored in: " . "upload/" . $_FILES["file"]["name"];


Wget does an HTTP POST to send file. I've also heard about $_POST, $HTTP_RAW_POST_DATA and file_get_contents(php://input) I'm not a php guy at all. So could someone please help me to get a valid solution? Thanks.

    I get contents of file this way:

    <?php $postdata = file_get_contents("php://input"); ?>

    $HTTP_RAW_POST_DATA - the same as the above but depends on php.ini (empty in my case)

    I need to store it in file on server side and it seems that filename was not sent either but it should be not a big deal.

    Please check, In the html form you defined enctype or not

    <form method="post" action="upload_file.php" enctype="multipart/form-data">
        <input type="file" name="file" id="file"/>

    If its not defined then also it might be not working. As, for file field this enctype in form is needed.

    wget can't be used for file uploads. File uploads require that the content type be multipart/form-data, but wget doesn't support this. From the man page:

    Wget does not currently support multipart/form-data' for transmitting POST data; only application/x-www-form-urlencoded'

    --post-file just posts ordinary form fields, it just gets the values from the contents of the file.

    You can do what you want with curl instead.

    curl -F file=@links.txt

    This is how you can do it with wget.

    wget -d --post-data="filedata=`base64 links.txt`&filename=links.txt"

    you can get filename and filedata from upload_file.php, and do whatever you want.

        $filename = $_POST['filename'];
        $filedata = base64_decode($_POST['filedata']);
