processing and php
Mar 2nd, 2009, 8:51pm  
Hello

I'm new to all this.  So be easy!

I'm trying to follow this tutorial...

http://www.learningprocessing.com/tutorials/php/php-persistence/

1. So i've got the php file and the saved.txt file on the server.  Where do i put the processing files (after having exported them?)

2. Also it says " text file to world readable and writable" i guess this means that in my ftp program (im using transmit on a mac) i right click, get info then tick the read, write boxes?

Thanks

1) After exporting, you have an HTML file and other files (at least a .jar). Put them where needed on the Web site. It is independent of the location of the PHP script.
2) Yes. "world" means everybody can read and write, not only your group or only the owner.

Hi, I just tried again.  I put all files into the one folder onto the server, changed the permissions of the saved.txt file (so that it is all read and writeable by ..global).

But nothing is appearing

my files are here

http://imd.dundee.ac.uk/~kchung/php
which include  

index.html
loading.gif
loadstrings.php
php.jar
php.java
php.pde
saved.txt

I'm sure im missing something fundamental.

thanks

http://www.learningprocessing.com/php/loadstrings.php
should be replaced by
http://imd.dundee.ac.uk/~kchung/php/loadstrings.php

You don't want to use another site to do this job... Smiley
Beside, you just cannot, unless you sign the applet.
No need to sign if the PHP script is on the same server as the applet.

i think thats what i already have... this is the code in the processing file


void setup() {
 size(600,200);
 background(255);
 smooth();
 loadData();
}

void draw() {
 noLoop();
}

void mousePressed() {
 String[] lines = loadStrings("imd.dundee.c.uk/~kchung/php/loadstrings.php?type=save&x=" + mouseX + "&y="+mouseY);
 println(lines[0]);
 loadData();
 redraw();
}

void keyPressed() {
 String[] lines = loadStrings("imd.dundee.c.uk/~kchung/php/loadstrings.php?type=clear");
 println(lines[0]);
 loadData();
 redraw();
 
}

void loadData() {
 background(255);
 String[] lines = loadStrings("imd.dundee.c.uk/~kchung/php/loadstrings.php?type=load");
 beginShape();
 stroke(0);
 noFill();
 for (int i = 0; i < lines.length; i++) {
   int[] vals = int(split(lines[i],","));
   if (vals.length > 1) {
     vertex(vals[0],vals[1]);
   }
 }
 endShape(CLOSE);
 for (int i = 0; i < lines.length; i++) {
   int[] vals = int(split(lines[i],","));
   if (vals.length > 1) {
     rectMode(CENTER);
     stroke(0);
     fill(175);
     rect(vals[0],vals[1],10,10);
   }
 }
}

That's not what I saw in the php.pde file on your site.
Beside, you have to specify an absolute address, with http://
