Image upload to a website

gerTheGreat

Hi I'm trying to add an image upload function to my project, can anyone suggest a good tutorial or resource, (maybe jsp or javascript??). I am trying to add this function to a website so that it will save the image to a predefined folder and rename the image too.

look up php or asp - scripts are already available that do precisely what you want

try searching for

php image uploader script or something similiar

[PHP]<form enctype="multipart/form-data" action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="2048000">
File: <input name="userfile" type="file" /><br />
<input type="submit" value="Upload" />
</form>

<?php
if (@is_uploaded_file($_FILES[&quot;userfile"]["tmp_name"])) {
copy($_FILES["userfile"]["tmp_name"], "/images/" . $_FILES["userfile"]["name"]);
echo "<p>File uploaded successfully.</p>";
}
?>[/PHP]

Something simple like this should get you started.

If you want to use jsp then the following code below is what u need.

- Put the code in a jsp e.g. processAttachment.jsp
- Use a multipart form as in example above and point form at the new jsp 'processAttachment.jsp'



<%@ page import="java.util.Vector"%>
<%@ page import="java.util.Date"%>
<%@ page import="java.text.SimpleDateFormat"%>
<%@ page import="com.oreilly.servlet.MultipartRequest" %>
<%@ page import="java.io.*" %>
<%@ page import="java.util.*" %>


<%@ page session="true"%>

<%

String returnMessage = "";
//String saveDirectory = application.getRealPath("/") + "/attachments/";
//String relativeDirectory = "../attachments/";
String saveFile = "";
String returnTo="listImages.jsp";
String sql = "";


boolean saveToDB = true;
byte dataBytes[] = new byte[1];
String file = "";
String contentType = request.getContentType();

try
{

MultipartRequest multi= new MultipartRequest(request,".",5*1024*1024);

Enumeration files=multi.getFileNames();
File f=null;
if(files.hasMoreElements())
{
System.out.println("TEST 9");
String name=(String)files.nextElement();
saveFile=multi.getFilesystemName(name);

String type=multi.getContentType(name);
f=multi.getFile(name);

InputStream is = new FileInputStream(f);
byte b[]=new byte[is.available()];
is.read(b);


File dir = new File(saveDirectory);
dir.mkdir();

FileOutputStream fileOut = new FileOutputStream(saveDirectory +"/" + saveFile);


fileOut.write(b);
//fileOut.write(dataBytes, startPos, (endPos - startPos));
fileOut.flush();
fileOut.close();

returnMessage +="<br>File saved as " +saveFile;

}

}
catch(Exception e)
{
returnMessage += "<br>An error occurred reading file. Please try again. " + e.getMessage();
// response.sendRedirect("attachments.jsp?requestId="+requestId+"&returnMessage="+returnMessage);
saveToDB=false;
}
