Hi GOPAL,
I can see two errors:
In your "barchart1.PHP", you have added some incorrect HTML lines, like:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
</head>
<body>
</body>
</html>
Note that a chart is not text/html. It is image/png. You cannot insert HTML into an image. Please remove all HTML lines from your code.
(b) The code require_once("C:\\wamp\\www\\ChartDirector\\lib\\phpchartdir.php"); is incorrect. In PHP syntax, the "\\" is an escape sequence. You need to use "\\\\" if you really mean a backslash character. Instead, I suggest you to use "/", like:
require_once("C:/wamp/www/ChartDirector/lib/phpchartdir.php");
There is also a potential issue in the code:
<IMG SRC="http://localhost/ChartDirector/phpdemo/barcharta.php">
Instead of using localhost, I suggest you just use:
<IMG SRC="/ChartDirector/phpdemo/barcharta.php">
Hope this can help.

Hi Gopal,
For some reasons, I cannot see the screen shot attachment.
Note that the forum has a 250 Kbytes limit for file attachment. To attach a file, please use the "Browse ..." button to browse to the file. If you directly enter the file name in the "File to Upload" field, you would need to press the "Send file" button to upload the file.
May be you can try to access the barcharta.php directly and inform me what is the output.
http://www.mydomain.com/ChartDirector\\phpdemo\\barcharta.php
If what you see is some garbage characters, it means there are some additional code in "barcharta.php" that switches the page to HTML (instead of image/png). Please attached the exact "barcharta.php" file so I can verify if there are any hidden extra characters.
If what you see is an empty page, please make sure you have enabled displaying error message in your web server. In your "php.ini", please set error_reporting to E_ALL, and display_errors to 1, then restart your server. Alternatively, you may try to add the following code at the beginning of barcharta.php to enable error message display.
ini_set('display_errors',1);
error_reporting(E_ALL);

Peter Kwan |
