[SOLVED] Help for a newb... drawing a string with GD

[torrobinson]

Hi. I've started looking into PHP.....just today. I'm interested in using it with the game Second Life. So far, I've managed to have chat from Second Life be picked up by a listening object, sent to a php file, and turned into a txt file. Then I have the text file reverse it's lines and show up on a webpage. Above this chatlog, I want to have a square image generated with the gd library that displays the detected "sim" (think of it like a server) and the location (the x, y, z within that server).

 

I am able to get the square drawn and the text "X:  Y:  Z:  SIM:" to appear, but there's no information. Here's what I've got for the location info:

 

<?php

   

    $info = $_GET['info']; //gives "13|216|611|Xappen"

 

list($x, $y, $z, $sim) = split('|',$info);

//x=13 , y=216, z=611, sim=Xappen

 

 

$map = ImageCreate (256, 256) or die ("Cannot Create image");

 

$bg_color = ImageColorAllocate ($map, 20, 20, 20); //greyish

 

$txt_color = ImageColorAllocate ($map, 255, 255, 255); //white text

 

ImageString ($map, 3, 5, 5, "X: " .$x, $txt_color);

ImageString ($map, 3, 5, 20, "Y: " .$y, $txt_color);

ImageString ($map, 3, 5, 35, "Z: " .$z, $txt_color);

ImageString ($map, 3, 5, 50, "Sim: " .$sim, $txt_color);

 

 

 

header ("Content-type: image/png");

 

 

 

 

imagepng($map);

?>

 

Now I KNOW for a fact that the script is getting the info. Because when I added the command to write it to a text file, it added "13|216|611|Xappen" just fine. It just won't "echo" it (when I tried), nor draw it on the image.

 

Help appreciated...I'm completely new to this and probably frustrated over some stupid mistake...

 

 

 

Here's where the work in progress is: http://torrobinson.3host.biz/sllog.html

Have you tried echo-ing your $x $y $z and $sim strings, just to make sure they're actually getting set a value.  Do this before your ImageString()

Yeah... When i'd echo it with some text like "x is:"... ,just the text would come through and not any x value. I'm posting this from my ipod so cant try anything now...

[torrobinson]

Oh before the image thing....I have tried moving it around but let me try tomorrow.... Why does it have to be after that?

[PHP Monkeh]

You could try explode rather than split:

 

<?php 
list($x, $y, $z, $sim) = explode("|", $info);
?>

 

Or instead of using list you could assign them all individually

 

<?php


$temp = explode("|", $info);

$x = $temp[0];
$y = $temp[1];
$z = $temp[2];
$sim = $temp[3];

?>

Thanks for the reply. I tried both of those, and echoing before the imagestring again but nothing came up. And again I tried replacing the echo with saving it to a txt file and it DID work. It has the string...just won`t do anything but save with it so far...

[PHP Monkeh]

Which string is it that you're saving to the text file?  The $x, $y etc or $info?

[torrobinson]

I tried with x and it worked. I`ll try with the other now.

Still I'm having this problem. Basically I can save the string to a file, but I can't echo it or use it in other functions...

 

Anybody have this before?

Nevermind. For some reason, writing it and having another script read it worked fine.
