My service provider is 1and1.com, they use PHP 5.  I run PHP on other sites there.  I didn't put an index page, because I didn't want any distraction....only the code I'm working on, in the folder.

One of the things that disturbed me is that the file Upload.phps seems to be html rather than PHP.  That's why it comes up as formatted code.

Now I'm really confused.  I took your advice and uploaded an index file. Now I get this error message:

i've got the same problem...

Code:

import processing.pdf.*;
import org.seltar.Bytes2Web.*;
PDFToWeb pdf;

void setup()
{
  size(800,600);
  pdf = new PDFToWeb(this);
}


void draw()
{
  background(0);
  stroke(255);
  line(random(width),random(height),random(width),random(height));
  pdf.addPage(); // if you want each frame to be on it's own page
}

void keyPressed()
{
  String url = "http://www.wollle.com/savetoweb/";
  if(key == 'p'){
    if(!pdf.isRecording()){
	pdf.startRecording();
    }else{
	pdf.save("pdf");
	pdf.post("test",url,"pdf-test",true);
    }
  }
  if(key == 'j'){
    ImageToWeb img = new ImageToWeb(this);
    img.save("jpg",true);
    img.post("test",url,"jpg-test",true,img.getBytes(g));
  }
  if(key == 't'){
    ImageToWeb img = new ImageToWeb(this);
    img.setType(ImageToWeb.TIFF);
    img.save("tiff",true);
    img.post("test",url,"tiff-test",true);
  }
  if(key == 'n'){
    ImageToWeb img = new ImageToWeb(this);
    img.setType(ImageToWeb.PNG);
    img.save("png",true);
    img.post("test",url,"png-test",true);
  }
  if(key == 'g'){
    ImageToWeb img = new ImageToWeb(this);
    img.setType(ImageToWeb.GIF);
    img.save("gif",true);
    img.post("test",url,"gif-test",true);
  }
} 

evokes this error:

somebody knows qhat to do?

Ah, I see, the ambiguity in the given example is in the line:
String url = "YOUR URL HERE";
It must be read:
String url = "http://www.yoursite.com/sketchName/Upload.php";
for example, ie. you must specify the PHP script to target in the URL.

Thanks, Robert, I actually enjoy the little intellectual challenges I meet in this forum... and I like to help, too!

You might want to change the line setting $destDir. In my original code, I set it to '../Uploads' ie. in an "Uploads" dir at same level than the folder where the Upload.php file is. In Seltar's version, it is 'saved/'.$title.'/' although I haven't guessed what $title is supposed to be here.
Set it to a path convenient for you, and with write access from the PHP script.

See Re: save to web --- image export

The problem is that so many things can go wrong if not correctly parametrized, it is hard to help without being in place...
