我有以下Google Charts
代碼,我試圖將它與MySQL
連接起來,我已經嘗試過所有可用的互聯網,但它仍然只顯示一個SQL結果集條目,儘管我有10個條目。在互聯網上我發現了$row_num
反事物,並且因爲將它包含在我的代碼中,我已經能夠查詢一個條目,但我想用它查詢所有條目。請幫我看看這個,讓我知道我一直在做什麼錯誤(如果有的話),以下是我的PHP代碼:谷歌圖表連接時只顯示MySQL的一個條目?
[<?php
``$dbhandle= new mysqli('localhost','root','8317','record');
//echo $dbhandle->connect_error();
$query= "SELECT * from download_manager";
$res= $dbhandle->query($query);
?>
<html>
<head>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
google.charts.load('current', {'packages':\['bar'\]});
google.charts.setOnLoadCallback(drawStuff);
function drawStuff() {
var data = new google.visualization.arrayToDataTable(\[
\['Title', 'No. of Downloads'\],
<?php
$total_rows = mysqli_num_rows($res);
$row_num = 0;
if (mysqli_num_rows($res) > 0) {
while($row=$res->fetch_assoc())
{
$row_num++;
if ($row_num == $total_rows){
echo "\['".$row\['filename'\]."',".$row\['downloads'\]."\]";
}
}
}
else
{
echo "0 results";
}
?>
\]);
var options = {
width: 800,
chart: {
'title': 'Top 10 Downloads',
subtitle: 'for the last month'
},
bars: 'horizontal', // Required for Material Bar Charts.
axes: {
}
};
var chart = new google.charts.Bar(document.getElementById('dual_x_div'));
chart.draw(data, options);
};
