Pie chart GD

[andyfresh]

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\

http://wwwroot\rateit\image3.php

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

$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...

Second Script

<? 
<img src="[URL unfurl="true"]http://localhost/image2.phpdata=10*9*11*10&label=Denmark*Germany*USA*Sweden"[/URL] /> 
?>

 

[jpadie]

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

<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:

<?
<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.

<?
echo '<img src="image2.php?data=10*9*11*10&label=Denmark*Germany*USA*Sweden">';
?>
