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.
Regards
Peter Kwan |
