    <p>This is my first question on stackoverflow, so if you have any comment on the way I put/explain it, I would gladly accept any pointers.</p> <p>So here it is:</p> <p>I want to sent both text and an image to a php script on a server. I can succesfully sent both apart from each other, but not together. Up till now I use this for a String:</p> <pre><code>String dataSend = URLEncoder.encode("User","UTF-8") +"="+URLEncoder.encode(username,"UTF-8"); URL url = new URL(urlCopyImage); URLConnection connection = url.openConnection(); connection.setDoOutput(true); OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream()); out.write(dataSend); out.close(); </code></pre> <p>For a image I use:</p> <pre><code>URL url = new URL(urlCopyImage); URLConnection connection = url.openConnection(); connection.setDoOutput(true); ImageIO.write(image,"PNG", connection.getOutputStream()); </code></pre> <p>Can i somehow combine these two?</p> <p>In the php script I merely use the <code>$_POST</code> to receive the string and for the image i use:</p> <pre><code>$incomingData = file_get_contents('php://input'); </code></pre> <p>Any tips are welcome. </p> <p>For the record, I use the php file to create a file containing this image on the server. The username is useful for specifying the directory.</p> <p>EDIT:</p> <p>Thanks to your answers I have been able to make it work, though I don't quite understand it yet.</p> <pre><code> MultipartEntity multipart = new MultipartEntity(); multipart.addPart("User", new StringBody(username)); ByteArrayOutputStream os = new ByteArrayOutputStream(); ImageIO.write(image, "png", os); InputStream is = new ByteArrayInputStream(os.toByteArray()); ContentBody cb = new InputStreamBody(is, "something.png"); multipart.addPart("Image", cb); HttpPost post = new HttpPost(urlCopyImage); post.setEntity(multipart); HttpClient client = new DefaultHttpClient(); HttpResponse response = client.execute(post); </code></pre> <p>I am handing the contentbody a inputstreambody which get the bytestream from the ImageIO. That's great. But what i don't get is what the second parameter of the inputstreambody is supposed to do. Although this works, it feels not right.</p> <p>Btw, this is the php code:</p> <pre><code>$user = $_POST['User']; copy($_FILES['Image']['tmp_name'],$filename); </code></pre> <p>I would be grateful if someone could explain what exactly I'm doing here. Thanks for your help!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
