Bug description:Setting filename for @... multipart uploads
Description:
------------
Using curl_setopt, you can make a multipart POST by passing an array of
parameters, and if preceded by an @, a file upload is created from the path
following the @.
curl_setopt(CURLOPT_POSTFIELDS, array('myfile'=>"@{$pathname}"));
However, I haven't been able to find a way to set the filename part of the
multipart description, so that it generates e.g.
Content-disposition: form-data; name="myfile";
filename="desiredfilename"
Content-Type: text/plain
That is, there isn't a way to get "desiredfilename" in there. The only
option seems to be for the filename part appears to come from the name of
the file within the path. The cURL command line interface seems to support
explicitly setting the filename different from the name of the source file
with
'-F "@path ; filename=whatever'
so presumably it is possible in the library, but not exposed through the
PHP binding.
In case it was merely passing on the string to the cURL library verbatim, I
tried:
curl_setopt(CURLOPT_POSTFIELDS, array('myfile'=>"@{$pathname};
filename=\"desiredfilename\""));
but that gives an error.
The problem is that the files I have are stored with simple numeric names
and the file names which an external user would know them by are in the
database that indexes the disk files. I have a workround which is to make a
temporary hard link to the file by its user name and give that to cURL, but
I don't think I should really need to do that.
Test script:
---------------
$now = time(); $tmpdirpath = "/tmp/enspub-{$now}-{$version->id}";
mkdir($tmpdirpath);
$tmpfilepath = "{$tmpdirpath}/" .
mb_ereg_replace('[/\\\\?%*:|"<>@~=+]', '_', $version->name); // replace
disallowed characters
link($version->pathname(), $tmpfilepath);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); /* tell me, not echo
*/
curl_setopt($ch, CURLOPT_POST, TRUE);
$post['file'] = "@{$tmpfilepath}";
/* ... and other $post settings ... */
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$data = curl_exec($ch);
/* ... error checking ... */
curl_close($ch);
@unlink($tmpfilepath);
@rmdir($tmpdirpath);
Expected result:
----------------
It works, but I'd like to be able to set the filename explicitly without
copying the file.
Actual result:
--------------
