------ Solution ------
The issue was on our server. It can only handle post requests if we put www in front of our domain name. So that's what caused the problems. I'm setting the first answer as THE answer since it worked once I sorted the URL out.
Original Question
I have a POST variable in my PHP script is always blank.
I've tried to change the variable's name, the content of the variable etc..
The problem has to reside in the java code, because when I var_dump() the request in php, it is null.
This is my scenario:
I let the user snap a photo, the photo is saved to the SD-card and I get the image's path, and eventually convert it to a Base64 string. I then want to post this base64 string to a php script that converts it back from Base64 and writes it as an image on my server's hard drive like so:
File f = new File(savedImagePath);
Bitmap bitmap = BitmapFactory.decodeFile(f.getPath());
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 30, stream);
byte [] byte_arr = stream.toByteArray();
String image_str = Base64.encodeToString(byte_arr, Base64.DEFAULT);
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://myURL/uploadImage.php");
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("image", image_str));
post.setEntity(new UrlEncodedFormEntity(pairs));
HttpResponse response = client.execute(post);
On the server end, this is what my PHP script looks like:
<?php
$base = $_POST["image"];
$binary=base64_decode($base);
header('Content-Type: bitmap; charset=utf-8');
$file = fopen('uploaded_image.jpg', 'w');
fwrite($file, $binary);
fclose($file);
echo "script done executing";
?>
This is an example of a Base64 string I'm trying to post:

This is the code for image:
ByteArrayOutputStream bao = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, bao);
byte [] ba = bao.toByteArray();
String ba1=Base64.encodeBytes(ba);
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("image",ba1));
This is the HTTP code for sending the image to the server:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://servername.com/uploadimage.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();

Base64 example
In PHP header file changes :
header('Content-Type: image/jpg; charset=utf-8');
$base=$_REQUEST['image'];
Have you tried reading the raw post data in PHP? Something like
$data = $xml = file_get_contents('php://input');
Have a look at this link for more info
http://www.codediesel.com/php/reading-raw-post-data-in-php/
just download the Base64.java http://iharder.sourceforge.net/current/java/base64/ & put that file in your project & then
just replace the
String image_str = Base64.encodeToString(byte_arr, Base64.DEFAULT);
this with
String image_str = Base64.encodeBytes(byte_arr);
replace this post.setEntity(new UrlEncodedFormEntity(pairs));
with
post.setEntity(new UrlEncodedFormEntity(pairs,HTTP.UTF_8));
Also check while importing the Base64 it will import file from your package & then post to server it will post.
in your php code just change
change this
$base = $_POST["image"];
to
$base = $_REQUEST['image'];
Try sending your data as below:
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, 60000); //1 min
HttpConnectionParams.setSoTimeout(httpParams, 60000); //1 min
HttpClient client = new DefaultHttpClient(httpParams);
HttpPost post = new HttpPost("http://myURL/uploadImage.php");
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("image", image_str));
post.setEntity(new UrlEncodedFormEntity(pairs, HTTP.UTF_8)); // as UTF-8
HttpResponse response = client.execute(post);
Is the HTTP-Response-Code you are getting 200?
If so, try setting these header-fields:
"Accept": "text/html"
"Accept-Language": "en"
"Content-Length": yourString.length
"Content-Type": "application/x-www-form-urlencoded"

We are working on an application which has 2 modules.
Android Application.
PHP Application
PHP backend application runs on an Apache Server with Centos Server.
Android application basically clicks images, send to the server along with gps coordinates etc form information.
Now the problem arises when the image file is created on the server. When android app calls the url the '&' character is replaced by & amp;, sometimes even by & amp;& amp; and this problem repeats in some of the cases. Once this conversion thing happens, image file is not created properly.
How it can be resolved?
Same code was working alright from past year, this problem begin to arise from last month only....
Following is the code for saving the images at server end :
foreach($_POST as $key => $value) {
$_POST[$x] = $value;
}
$base=$_REQUEST['image'];
$nm=$_REQUEST['name'];
$binary=base64_decode($base);
if(file_exists("uploaded_images/".$nm.".jpg")) {
unlink("uploaded_images/".$nm.".jpg");
}
header('Content-Type: bitmap; charset=utf-8');
$str="uploaded_images/".$nm.".jpg";
$file = fopen($str, 'wb');
fwrite($file, $binary);
fclose($file);
chmod($file,0777);
$ok=1;
echo $ok;
Following is the error log which is encountered if image is not properly saved.
PHP Notice: Undefined index: name in /var/www/html/cbd/def/filesubmitnew.php
Note : filesubmitnew.php is the file name of the above code.
In Android Application for this is how the url is called:
To Create image:
if(buttontext.equals("Img1")) {
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
v.setImageBitmap(bitmap);
buttontext="";
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 20, stream);
byte [] byte_arr = stream.toByteArray();
String str1 = Base64.encodeBytes(byte_arr);
System.out.println(""+str1);
if(feuser.equals("offline_access")){
System.out.println("++==--SD CARD");
File externalStorage = Environment.getExternalStorageDirectory();
File folder = new File(externalStorage.getAbsolutePath() +mainFolder + caseId);
if (!folder.exists()) {
folder.mkdir();
}
File pictureFile = new File(externalStorage.getAbsolutePath()+mainFolder+caseId, "1.jpg");
System.out.println(pictureFile);
pictureFile.createNewFile();
FileOutputStream fOut = new FileOutputStream(pictureFile);
OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut);
myOutWriter.append(str1);
myOutWriter.close();
fOut.close();
Toast.makeText(getBaseContext(),"Done writing SD "+pictureFile,Toast.LENGTH_SHORT).show();
}
else {
Intent i = new Intent ("com.keyboardlabs.newbankge.CameraUploadService");
try {
i.putExtra("imageparams", str1);
i.putExtra("ref_id", caseId);
i.putExtra("imageId", "1");
i.putExtra("CaseType",caseType);
}
catch (Exception e) {
e.printStackTrace();
}
getApplicationContext().startService(i);
}
Following is the camerauploadservice

I need to upload a bitmap image to my server but it takes a lot of time while uploading. I use base64 to encode the image and decode it while adding it to the database as Blob.
I want to know what is the other alternative way to upload an image and which one is more efficient.
Here what I have been trying:
HttpParams params = new BasicHttpParams();
params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION,HttpVersion.HTTP_1_1);
HttpConnectionParams.setConnectionTimeout(params, 20000);
HttpConnectionParams.setSoTimeout(params, 15000);
DefaultHttpClient httpClient = new DefaultHttpClient(params);
HttpPost httpPost = new HttpPost(url);
namevaluepair.add(new BasicNameValuePair("icon", getStringDrawing(bmIcon)))
httpPost.setEntity(new UrlEncodedFormEntity(namevaluepair));
httpClient.execute(httpPost);
public static String getStringDrawing(Bitmap bm) {
String image_str = "";
try {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
byte[] byte_arr;
bm.compress(Bitmap.CompressFormat.PNG, 90, stream);
byte_arr = stream.toByteArray();
image_str = Base64.encodeBytes(byte_arr);
} catch (NullPointerException e) {
}
return image_str;
}
In PHP I tried to save it in Blob and in folder here some of the codes:
$Drawing = $_POST {'drawing'};
$buffer = base64_decode($Drawing);
$file = fopen("PostImage/P".$ID.".png", 'wb');
fwrite($file, $buffer);
fclose($file);
The second try:
$Drawing = $_POST {'drawing'};
$buffer = base64_decode($Drawing);
$buffer = mysql_real_escape_string($buffer);
$query = "INSERT INTO `drawposts` (`PostID`, `UserID`,`DatePost`, `Drawing`) VALUES (NULL,'$UserID','$Date','$buffer')";
$sth = mysql_query($query);
Look at the FileEntity . Something like
File Picture = new File("/path/to/jpg");
FileEntity f = new FileEntity(picture,"application/octet-stream");
HttpPost post = new HttpPost("my URL");
post.setEntity(f);
post.setHeader("Content-type", "application/octet-stream");
I am trying to upload an image to a PHP page along with some other info about the image so the PHP page knows what to do with it. Currently, I am getting away with it using this:
URL url = new URL("http://www.tagverse.us/upload.php?authcode="+WEB_ACCESS_CODE+"&description="+description+"&userid="+userId);
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
OutputStream os = connection.getOutputStream();
InputStream is = mContext.getContentResolver().openInputStream(uri);
BufferedInputStream bis = new BufferedInputStream(is);
int totalBytes = bis.available();
for(int i = 0; i < totalBytes; i++) {
os.write(bis.read());
}
os.close();
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String serverResponse = "";
String response = "";
while((response = reader.readLine()) != null) {
serverResponse = serverResponse + response;
}
reader.close();
bis.close();
Is there a more elegant solution to this besides having a GET/POST hybrid? I feel as if this is sloppy, but for all I know it is a perfectly acceptable solution. If there is a better way of doing this, I'd appreciate being pointed in the right direction. Thanks!
PS: I am familiar with how you would, under normal conditions, interact with a PHP page via POST:
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://www.tagverse.us/login.php");
try {
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("authcode", WEB_ACCESS_CODE));
pairs.add(new BasicNameValuePair("username", username));
pairs.add(new BasicNameValuePair("password", password));
post.setEntity(new UrlEncodedFormEntity(pairs));
client.execute(post);
}
Essentially what I'd like to do is combine these two methods, but because I work with an HttpURLConnection object rather than a HttpPost object, it isn't as simple as just merging the two.
Thank you!
You can try an take a look at the answer I added for this similar question:

}
}
and even took some php code copied some php code which i am running in local sever using wamp server. There is no response in the local server.
and this is my php code.
<?php
$base=$_REQUEST['image'];
echo $base;
// base64 encoded utf-8 string
$binary=base64_decode($base);
// binary, utf-8 bytes
header('Content-Type: bitmap; charset=utf-8');
// print($binary);
//$theFile = base64_decode($image_data);
$file = fopen('test.jpg', 'wb');
fwrite($file, $binary);
fclose($file);
echo '<img src=test.jpg>';
?>
Can any one help me in this. thanks in advance.
A nice tutorial for uploading image to server-
http://coderzheaven.com/2011/04/android-upload-an-image-to-a-server/
Edit:
You just need to change this according to your local server:
HttpPost httppost = new HttpPost("http://<local ip address>/android/upload_image.php");
// For example,in my code,i used:
// HttpPost httppost = new HttpPost("http://192.168.100.47/android/upload_image.php");
Did you manage to solve the problem? I did get it to work when i changed $base=$_REQUEST['image']; => $base=$_POST['image']; and commented out the following line header('Content-Type: bitmap; charset=utf-8'); Btw, did try to convert the code to use HttpURLConnection api?
I am trying to get a Android device to send some information to a local host. I believe I have the Android sending the information, but my PHP code is not accepting or not displaying the code. I have attached my code, is there something I have missed? I am running wamp server also, and have put the permissions into the manifest.
Java Code: #

nameValuePairs.add(new BasicNameValuePair("parameterName1", "git"));
nameValuePairs.add(new BasicNameValuePair("parameterName2", "git"));
// Send POST message with given parameters to the HTTP server.

baf.append((byte) current);
}
bytesSent = new String(baf.toByteArray());

Make sure the Content-Type HTTP header is getting set. Try replacing
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
with this
HttpEntity entity = new UrlEncodedFormEntity(nameValuePairs);
httppost.addHeader(entity.getContentType());
httppost.setEntity(entity);
Also, instead of response.toString(), try EntityUtils.toString(response.getEntity()) if you want to see the body of the response
