This is a way for android to POST a file upload to a php script. I had
a bit of trouble figuring out the ins and outs of the http client
situation, but this is what works for me (hope someone finds it
helpful):
Notes:
Expect/continue handshaking needed to be disabled to avoid getting 417
errors from lighttpd. Doesn't work without an sdcard yet, as there is
no Content-Length header associated with uploading an OutputStream as
opposed to a File object, and writing to files is only allowed on the
sdcard (as far as I know, please correct me if there is a way to do
this).
Dependencies:
apache-mime4j-0.5.jar
log4j-zeroconf.jar
httpmime-4.0-beta1.jar
upload.php:
<form enctype="multipart/form-data" action="upload.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Choose a file to upload: <input name="uploadedfile" type="file" /><br /
>
<input type="submit" value="Upload File" />
</form>
<?php
$to_file = "tmp/" . basename($_FILES['uploadedfile']['name']);
$from_file = $_FILES['uploadedfile']['tmp_name'];
if (move_uploaded_file($from_file, $to_file)) {
echo "Successful upload";
?>
<a href="<?php echo $to_file;?>"><?php echo $to_file;?></a>
<?php
} else {
echo "Unsuccessful upload";
}
?>
