Hi, everyone.

I am having a hard time to update a txt file （permission set to 777） on web server by using the code here:

http://wiki.processing.org/index.php?title=Saving_files_to_a_web-server


I have a txt file name data.txt and a php file named update.php  at http://www.mydomain.com/Online/outgoing/, and all the codes are shown below. But when I ran the program, I got an error, and do not know how to fix it. Can anyone help me? Any hint and guide is very appreciated. Thanks

Bo


The code of processing on client part is :

1. String men;
   String[] data;
   String url;
   String title;
   String ext;
   String folder;
   boolean popup;
   
   
   void setup() {
   
      title="data";
      ext="txt";
      url = "http://www.mydomain.com/Online/outgoing/";
      folder = "http://www.mydomain.com/Online/outgoing/";
      men = "Chernenko,Andropov, Brezhnev";
      data = split(men, ',');
      popup = false;
     
      saveToWeb_saveFileString(title, ext, folder, data, popup);
   }
   
   void draw(){
2.     //do nothing
   
3. }
   
4. 
   void saveToWeb_saveFileString(String title, String ext, String folder, String[] data, boolean popup)
   {
     println("SAVING File START"); 
     postData(title+"_"+year()+nf(month(),2)+nf(day(),2)+"-"+nf(hour(),2)+nf(minute(),2)+nf(second(),2),ext,folder,join(data,"\n").getBytes(),popup);
     println("SAVING File STOP"); 
   }
    
    
   void postData(String title, String ext, String folder,  byte[] bytes, boolean popup)
   {
     try{
       URL u = new URL(url+"saveFile.php?title="+title+"&ext="+ext+"&folder="+folder);
       URLConnection c = u.openConnection();
       // post multipart data
    
       c.setDoOutput(true);
       c.setDoInput(true);
       c.setUseCaches(false);
    
       // set request headers
       c.setRequestProperty("Content-Type", "multipart/form-data; boundary=AXi93A");
    
       // open a stream which can write to the url
       DataOutputStream dstream = new DataOutputStream(c.getOutputStream());
    
       // write content to the server, begin with the tag that says a content element is comming
       dstream.writeBytes("--AXi93A\r\n");
    
       // discribe the content
       dstream.writeBytes("Content-Disposition: form-data; name=\"data\"; filename=\"whatever\" \r\nContent-Type: image/jpeg\r\nContent-Transfer-Encoding: binary\r\n\r\n");
       dstream.write(bytes,0,bytes.length);
    
       // close the multipart form request
       dstream.writeBytes("\r\n--AXi93A--\r\n\r\n");
       dstream.flush();
       dstream.close();
    
       // read the output from the URL
       try{
         BufferedReader in = new BufferedReader(new InputStreamReader(c.getInputStream()));
         String sIn = in.readLine();
         boolean b = true;
         while(sIn!=null){
           if(sIn!=null){
             if(popup) if(sIn.substring(0,folder.length()).equals(folder)) link(url+sIn, "_blank");
             System.out.println(sIn);
           }
           sIn = in.readLine();
         }
       }
       catch(Exception e){
         e.printStackTrace();
       }
     }
    
     catch(Exception e){
       e.printStackTrace();
     }
   }

      The php file on server side is shown below:

1. ;<?
   $Title = $_GET['title'];
   $Ext = $_GET['ext'];
   $folder = $_GET['folder'];
   $savepath = dirname($_SERVER["PATH_TRANSLATED"]);
    
   $filename = $Title.".".$Ext;
   while(file_exists($folder."/".$filename))
     $filename = $Title."-".rand(2,500).".".$Ext;
    
    if (is_uploaded_file($data))
    {
      $newfile = $savepath."/".$folder."/".$filename;
      if (!copy($data, $newfile))
      {
         // if an error occurs the file could not
         // be written, read or possibly does not exist
         echo "Error #1 Uploading File.";
         exit();
      }else{
         echo $folder."/".$filename;
      }
    } else {
      echo "Error #2 Uploading File.";
      exit();
    }
   ?>
