我有一些用于显示图形数据的JS代码:
series: [{
name: 'Year 1800',
data: [107, 31, 635, 203, 2]
}, {
name: 'Year 1900',
data: [133, 156, 947, 408, 6]
}, {
name: 'Year 2008',
data: [973, 914, 4054, 732, 34]
}]
我需要获取数据以在PHP的while循环中显示。我已经试过了:
<?php
$sql="SELECT *, COUNT(category) AS my_groupcount from tickets where deleted = '' and DAY(datetime) = '".$day."' and MONTH(datetime) = '".$month."' and YEAR(datetime) = '".$year."' group by category order by datetime ASC ";
$rs=mysql_query($sql,$conn);
while($result=mysql_fetch_array($rs))
{
echo "name: 'Cat ".$result["category"]."',";
echo "data: [".$result["my_groupcount"]."]";
echo "}, {";
}
?>
我需要将票证表中的类别列进行分组并显示每个类别的图表,但是它不起作用-我认为它是因为在while循环中,其以
}, {
结尾,但是我需要它以}]
结尾我如何解决这个问题-票证表中类别项目的数量一直在变化,因为用户能够添加/删除类别。
最佳答案
<?php
$sql="SELECT *, COUNT(category) AS my_groupcount from tickets where deleted = '' and DAY(datetime) = '".$day."' and MONTH(datetime) = '".$month."' and YEAR(datetime) = '".$year."' group by category order by datetime ASC ";
$rs=mysql_query($sql,$conn);
$first = true;
echo 'series: [{';
while($result=mysql_fetch_array($rs))
{
if(!$first) {
echo "}, {";
} else {
$first = false;
}
echo "name: 'Cat ".$result["category"]."',";
echo "data: [".$result["my_groupcount"]."]";
}
echo '}]';
?>
