Hi,

Im currently trying to add a pie chart to my website using GD. However when I run the following script the error Parse error: parse error in c:\inetpub\ on line 2

comes up. I have used the following script to create the pie chart. I then use the second script to call the pie chart.

Can anyone help?

First script
Code:
<?php
$show_label = true; // true = show label, false = don't show label.
$show_percent = true; // true = show percentage, false = don't show percentage.
$show_text = true; // true = show text, false = don't show text.
$show_parts = false; // true = show parts, false = don't show parts.
$label_form = 'square'; // 'square' or 'round' label.
$width = 199;
$background_color = 'FFFFFF'; // background-color of the chart...
$text_color = '000000'; // text-color.
$colors = array('003366', 'CCD6E0', '7F99B2','F7EFC6', 'C6BE8C', 'CC6600','990000','520000','BFBFC1','808080'); // colors of the slices.
$shadow_height = 16; // Height on shadown.
$shadow_dark = true; // true = darker shadow, false = lighter shadow...

$height = $width/2;
$data = explode('*',$data);

if ($label != '') $label = explode('*',$label);

for ($i = 0; $i < count($label); $i++) 
{
	if ($data[$i]/array_sum($data) < 0.1) $number[$i] = ' '.number_format(($data[$i]/array_sum($data))*100,1,',','.').'%';
	else $number[$i] = number_format(($data[$i]/array_sum($data))*100,1,',','.').'%';
	if (strlen($label[$i]) > $text_length) $text_length = strlen($label[$i]);
}

if (is_array($label))
{
$antal_label = count($label);
$xtra = (5+15*$antal_label)-($height+ceil($shadow_height));
if ($xtra > 0) $xtra_height = (5+15*$antal_label)-($height+ceil($shadow_height));

$xtra_width = 5;
if ($show_label) $xtra_width += 20;
if ($show_percent) $xtra_width += 45;

}

{
	$fill_color[] = colorHex($img, $colorkode);

	{
		imagefilledellipse($img,$width+11,$label_place+5,10,10,colorHex($img, $colors[$i % count($colors)]));
		imageellipse($img,$width+11,$label_place+5,10,10,colorHex($img, $text_color));
	}
	else if ($label_form == 'square' && $show_label)

		imagerectangle($img,$width+6,$label_place,$width+16,$label_place+10,colorHex($img, $text_color));
	}

	if ($show_percent) $label_output = $number[$i].' ';
	if ($show_text) $label_output = $label_output.$label[$i].' ';
	if ($show_parts) $label_output = $label_output.$data[$i];

	imagestring($img,'2',$width+20,$label_place,$label_output,colorHex($img, $text_color));

	else
	{
		($R < 220) ? $R += 35 : $R = 255;
		($G < 220) ? $G += 35 : $G = 255;
		($B < 220) ? $B += 35 : $B = 255;	
	}

}
function OutputImage($img) 
{
	header('Content-type: image/jpg');
	ImageJPEG($img,NULL,100);
}
?>

Second Script
Code:
<? 
<img src="[URL unfurl="true"]http://localhost/image2.phpdata=10*9*11*10&label=Denmark*Germany*USA*Sweden"[/URL] /> 
?>
 
is one of these scripts image3.php?

in second script i wound suggest putting a questionmark between php and dataas i'd guess you want data to be available in the query string rahter than a part of the filename?
 
Hi there,

Iv changed the piece of code as suggested (stupid mistake) So it now reads
Code:
<img src="image2.php?data=10*9*11*10&label=Denmark*Germany*USA*Sweden">

However it now appears like I have typed in the incorrect file name. However I know this isnt true as I linked it to a normal image and everything was fine.

Any suggestions

Andy
 
This:
Code:
<?
<img src="image2.php?data=10*9*11*10&label=Denmark*Germany*USA*Sweden">
?>
makes no sense. You're opening php brackets and then not outputting php but HTML. Since there's no php in this script, I would just output plain html, or if you want to use php, you should use echo or print.
Code:
<?
echo '<img src="image2.php?data=10*9*11*10&label=Denmark*Germany*USA*Sweden">';
?>
