Hey Image Thing

[burnside]

Hello, i really dont know how to explane this but ill try best i can, I am making a script where if you have say 100 points but only 10 left it will show you in a images like a bar line etc ... i have tried but it doesnt seem to do what i want sorry if its not much help.

 $percent = $info[points] / $info[points_left];
$percent = $percent * 100;
$percent = round($percent);
$leftpercent = 100 - $percent;
$imagesss = "<tr><Td width=35 bgcolor=gray><img src=img\left.gif width=$percent height=10></td>"; 

echo $imagesss ; 

its showing the image but only at the current points left where i want it to show points and current points if you get me :\

Do mean something like this one?

 

::bar.php::

<?php
// set dimensions
     $w = 102;
     $h = 10;
// create image
     $im = imagecreate($w, $h);
// set colours to be used
     $bg = imagecolorallocate($im, 0xE0, 0xE0, 0xE0);
     $black = imagecolorallocate($im, 0x00, 0x00, 0x00);
     $red  = imagecolorallocate($im, 0xFF, 0x00, 0x00);
     $green  = imagecolorallocate($im, 0x50, 0xB6, 0x30);  
// draw border
     imagerectangle($im, 0,0,$w-1,$h-1,$black);
// get value and max value from query string
     $val = isset($_GET['val']) ? $_GET['val'] : 0;
     $max = isset($_GET['max']) ? $_GET['max'] : 100; 
// calculate dimensions of inner bar
     $barw = $max ? floor(($w-2) * $val / $max) : 0;
     $barh = $h - 2;
// draw inner bar
 if ($barw)
     {
        $barcolor = $val < 50 ? $red : $green;
     	imagefilledrectangle($im, 1, 1, $barw, $barh, $barcolor);
     }
// send image header
     header("content-type: image/png");
// send png image
     imagepng($im);
     imagedestroy($im);
?>

 

Call with something like

<?php
"echo <img src='bar.php?val=$current&max=$totalpoints'>";

You can also do it with two different colored tables.
