[英]JSON data not showing in highstock candlestick chart using PHP and SQL
我正在嘗試顯示一個高檔燭台圖表 ,但我無法實現它。 我的網站顯示圖表應該是空白,但圖表中沒有顯示任何內容。 如何修復它以顯示圖表?
我有兩個腳本:
datachart.inc.php:
<?php
include '../dbh.php'; //It connects to the database
$sql = "SELECT * from table";
$result = $conn->query($sql);
$row = mysqli_fetch_array($result);
$data = array();
$count = 0;
while ($row=mysql_fetch_array($result))
{
$newdate = strtotime($row['date']) * 1000;
$data[] = array($newdate, (float)$row['open'], (float)$row['high'],
(float)$row['low'], (float)$row['close']);
$count++;
}
echo json_encode($data);
?>
index.htm的:
<!DOCTYPE HTML>
<HTML>
<BODY>
<script>
$(function() {
$.getJSON('datachart.inc.php', function(data) {
// create the chart
chart = new Highcharts.StockChart({
chart : {
renderTo : 'container',
},
rangeSelector : {
selected : 1
},
title : {
text : 'Test Price'
},
series : [{
type : 'candlestick',
name : '',
data : data,
tooltip: {
valueDecimals: 2
},
dataGrouping : {
units : [
['week', // unit name
[1] // allowed multiples
], [
'month',
[1, 2, 3, 4, 6]]
]
}
}]
});
});
});
</script>
<div id="container" style="height: 250px; min-width: 250px"></div>
</BODY>
</HTML>

解決了:
1)導入javascript文件
2)刪除“$ row = mysqli_fetch_array($ result);”
3)將“while($ row = mysql_fetch_array($ result))”更改為“while($ row = mysqli_fetch_array($ result))”
