pChart does not render to web browser, only shows missing image
pCharts documentation says that you should be able to render the image to the browser using this code.
mypic.php
$myPicture->stroke;
mypage.html
<IMG SRC=‘mypic.php‘>
The img tag is supposed to invoke the php script. Within the PHP script, the stroke function se开发者_运维问答ts the content-type: image/png.
So here is what I have:
netsales.php
<?php
include('../class/pData.class.php');
include('../class/pDraw.class.php');
include('../class/pImage.class.php');
/* query sales and create new image */
$myPicture->stroke;
?>
index.php
<?php
include ('netsales.php');
?>
<!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=UTF-8" />
</head>
<body>
<div>
<img src="netsales.php" />
</div>
</body>
</html>
I'm not getting any errors, just the red X for a missing image.
try removing the
<?php
include ('netsales.php');
?>
From index.php, and add
header('Content-Type: image/png');
Before the Stroke call.
I try something like this and works:
//html file//////////////////////
<?php include ('my.php'); ?>
<html>
<head></head>
<body>
<div> <img src="my.php" /> </div>
</body>
</html>
///////////////////////////////////
//my.php file/////////////////////////
<?php
/* pChart library inclusions */
include("pChart/class/pData.class.php");
include("pChart/class/pDraw.class.php");
include("pChart/class/pImage.class.php");
//...
$myPicture->autoOutput("picture.png");
?>
///////////////////////////////////
I just got it working for me I had comment include function in HTML file:
<?php //include ('my.php'); ?>
加载中,请稍侯......
