PHP not accepting uploaded files from HTTP POST

[Debbie-Leigh]

Hi,

I hope someone can help me with this. I've created a php script to POST files to a php page, which should receive them and save them.

So far, a basic form-urlcoded POST works and displays the sent message, but when I try to include a mime encoded stream with the files using multipart/form-data, neither $FILES, $POST nor any of the other variables that are meant to hold the uploaded file details have anything in them.

The mime stream I'm sending is:

POST /sitemaint/formdatapost.php HTTP/1.1\r\n
Host: allaboutpnp\r\n
MIME-Version: 1.0\r\n
Content-Type: multipart/form-data;\r\n
\tboundary=\"=_3248657b0008c22f2882633a6766d5cd\"\r\n
Content-Length: 6099\r\n
\r\n
--=_3248657b0008c22f2882633a6766d5cd\r\n
Content-Disposition: form-data\r\n
Content-Type: text/plain\r\n
\r\n
Action=process\r\n
--=_3248657b0008c22f2882633a6766d5cd\r\n
Content-Disposition: form-data\r\n
Content-Type: multipart/mixed;\r\n
\tboundary=\"=_0bfabab46ee6d6eff7e4198f18ba0195\"\r\n
\r\n
--=_0bfabab46ee6d6eff7e4198f18ba0195\r\n
Content-Type: application/octet-stream\r\n
Content-Transfer-Encoding: base64\r\n
Content-Disposition: inline; filename=\"logo-hdr.gif\"\r\n
Content-ID: <6c419e0f9466b7bc682e2ae11017ae13>\r\n
\r\n
(image contents here)
--=_0bfabab46ee6d6eff7e4198f18ba0195--\r\n
--=_3248657b0008c22f2882633a6766d5cd\r\n
Content-Type: application/octet-stream\r\n
Content-Transfer-Encoding: base64\r\n
Content-Disposition: attachment; filename=\"tld.txt\"\r\n
\r\n
(attached file contents here)
--=_3248657b0008c22f2882633a6766d5cd--\r\n"

Can anyone spot or suggest anything that could be wrong, please?

hard to guess what is the problem without the actual code.. anyhow, using print_r() to see what is being passed and what isn't.

Yep, I did a print_r on all the global arrays just to make sure the files weren't hiding in some unexpected place and as I said the $FILES and $POST arrays were completely empty.

There's quite a lot of code involved to build and send the post, but the salient points are:

The code to post the request is:

$aParms["Action"] = "process";
$strFile   = funGetFile("(path_to_images)images/image.gif");
$aImages[] =       array("body"       => $strFile
			,"name"       => "image.gif"
			,"c_type"     => ""
			);
$strFile   = funGetFile("(path_to_test)test/test.txt");
$aAttachments[] =  array("body"       => $strFile
			,"name"       => "test.txt"
			,"c_type"     => ""
			,"encoding"   => ""
			);

$objPost  = new http();
$objPost->Connect($strHost);
$strStatus = $objPost->Post("(test_path)formdatapost.php", $aParms, $aImages, $aAttachments);
$objPost->Disconnect();

if  ($strStatus == 200):
	$strBody  = $objPost->getBody();
else:
	$strBody .= BR . "There was a problem posting the data. The error message returned was:" . BR . $objPost->getStatus() . " - " . $objPost->getStatusMessage();
endif;

The code to receive the request is:

$strTargetImg  = "(test_path)formdatatest/" . $_FILES[0]["name"];
$strTargetAtt  = "(test_path)formdatatest/" . $_FILES[1]["name"];

$booImgWorked = funCopyUploadedFile($_FILES[0], $strTargetImg);
$booAttWorked = funCopyUploadedFile($_FILES[1], $strTargetAtt);

$strBody       = BR . "The action requested was: $pstAction";
$strBody      .= BR . "The image sent was: " . $_FILES[0]["name"];
$strBody      .= BR . "<img src=\"(url_path) . $_FILES[0]["name"]\">" . BR;
$strBody      .= BR . "The attachment sent was: " . $_FILES[1]["name"];
$strBody      .= BR . funGetFile($strTargetAtt);

echo $strBody;

This http class just formats the request and sends it. It calls another class which formats the mime message, which I included in my first post. The POST bit does work as the text in $strBody is passed back and displayed perfectly OK, it's just that the files aren't appearing anywhere at the other end, so they can't be saved and so don't appear in the message.

Because of this, I suspect the problem perhaps lies somewhere in the format of the mime message or the way I need to accept it on the receiving end.

My main problem is that I'm not sure how the data is presented at the receiving end. I assumed it would be the same as when you submit a form i.e. the file details are automatically presented in the $_FILES global, but when that didn't happen, I didn't know where to turn.
