Hi,
how can I connect the Google Pie Chart with a MySQL database?
My following code doesn't work :-(
<?php
$con=mysqli_connect("localhost","User","Password,"testdb");
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql = 'SELECT COUNT(*)-SUM(testcolumn) AS 'YesOrNo' FROM testtable';
$yes = mysql_query ( $sql );
$sql = 'SELECT COUNT(*)-SUM(testcolumn) AS 'YesOrNo' FROM testtable';
$no = mysql_query ( $sql );
?>
<html>
<head>
<script type="text/javascript"
src="https://www.google.com/jsapi";></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['YesOrNo', 'Mount'],
['Yes', $yes],
['No', $no]
]);
var options = {
title: 'Test Pie Chart',
is3D: true,
};
var chart = new
google.visualization.PieChart(document.getElementById('piechart_3d'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id="piechart_3d" style="width: 900px; height: 500px;"></div>
</body>
</html>
Thanks for helping!
