How to "download" a multi-part file at the "server" side?

I just came across http://www.w3schools.com/php/php_file_upload.asp, and
tested it..
It works fine, when the file is uploaded via a form.

It does seem that the client-method might indeed play a role.
Here is my Java code for uploading the file ::

###################################################
HttpClient httpclient = new DefaultHttpClient();

httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION,
HttpVersion.HTTP_1_1);

HttpPost httppost = new HttpPost(URL);
File file = new File("/path/to/png/file.png");

// Send the image-file data as a Multipart-data.
MultipartEntity mpEntity = new MultipartEntity();
ContentBody cbFile = new FileBody(file, "image/png");
mpEntity.addPart("userfile", cbFile);

httppost.setEntity(mpEntity);

HttpResponse response = httpclient.execute(httppost);
###################################################

Any ideas if making a change at the client (Java) OR/AND server (PHP) might
do the trick?

Hi all.
I intend to implement a use-case, wherein the client uploads a file in
multi-part format, and the server then stores the file in a mysql database
(after "downloading it at the server side).
I have been unable to find any immediate answers through googling; I will
be grateful if someone could start me in a direction to achieve the
"downloading at server via php" requirement.
(Don't think it should matter, but I use Java to upload a file in
multi-part format).
I will be grateful for some pointers.
Thanks in advance
Thanks and Regards,
Ajay

Fairly easy:

Does not work :(

As per the code-snippet I pasted,
$_FILES["userfile"]["name"]

should be
/path/to/png/file.png

However, $_FILES["userfile"]["name"] is empty.

Hi all.

1.
I could have the proper "$_FILES["userfile"]["name"]" been echoed back, by
replacing
ContentBody cbFile = new
FileBody(file, "image/png");

with
ContentBody cbFile = new
FileBody(file);

2.
However, now I am stuck with the following server-side code.
No matter what I do, I always get a "no" echoed back (specifying that the
file is not copied to its target place).

###########################################################################
<?php

$headers = apache_request_headers();

foreach ($headers as $header => $value)
{
if($header == "active_window_title")
{
$active_window_title = $value;
break;
}
}

$target_path = "/home/ajay/success.png";

move_uploaded_file($_FILES["userfile"]["tmp_name"], $target_path);
if(file_exists($target_path))
{
echo "yes";
}
else
{
echo "no";
}

echo "\n" . $_FILES["userfile"]["name"]; # I always get the proper
file-name echoed.

?>
####################################################################################

Any ideas what stupidity am I making in the PHP code?

Ajay, try changing your mpEntity to:

new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE)

See if it makes a difference.

Try

If(move_uploaded_file($_FILES["userfile"]["tmp_name"], $filename){
Echo "file moves";
}else{
Echo "file doesn't move";
}

Also check the target directory permissions for writing

Damn... it was a SeLinux firewall :(

I disabled everything on the server, via
sudo setenforce 0
sudo service iptables stop
sudo service ip6tables stop

and the file was then copied onto the server perfectly !!

Sorry for the bother; and thanks a ton to everyone who spared their time in
looking into the (stupid) query of mine.

Sorry again.
