如何从 MySQL 数据库的多个表中获取数据并使用 PHP 对其进行操作以显示图形？

Question

我想为销售、采购和转移的年度报告制作图表。 MySQL 查询和 PHP 代码和图形代码如下。

MySQL 要求

SALES QUERY

SELECT COUNT(id) AS sales, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM sales 

WHERE `date` LIKE '2015%'

GROUP BY DATE_FORMAT(date, '%Y-%M')
ORDER BY DATE_FORMAT(date, '%Y-%M') ASC

PURCHASES QUERY

SELECT COUNT(id) AS num, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM purchases 

WHERE `date` LIKE '2015%'

GROUP BY DATE_FORMAT(date, '%Y-%M')
ORDER BY DATE_FORMAT(date, '%Y-%M') ASC

TRANSFERS QUERY

SELECT COUNT(id) AS num, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM transfers 

WHERE `date` LIKE '2015%'

GROUP BY DATE_FORMAT(date, '%Y-%M')
ORDER BY DATE_FORMAT(date, '%Y-%M') ASC

现在，销售查询返回以下数据

sales, dataofmonth
1   2015-December
3   2015-January

数据库中只有一月和十二月的数据。所以，我想在其他月份显示0。

图表/图表

我正在使用 high-charts 来显示图表页面，使用以下代码，效果很好，但我无法使用 PHP.

使其动态化

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script src="http://code.highcharts.com/highcharts.js"></script>

<script type="text/javascript">
        jQuery.noConflict();

        var example = 'line-basic', 
        theme = 'default';

        (function($){ // encapsulate jQuery


            $(function () {
    $('#container').highcharts({
        title: {
            text: 'Monthly Average Report',
            x: -20 //center
        },/*

        xAxis: {
            categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',

        },
        yAxis: {
            title: {

            },
            plotLines: [{

                width: 1,
                color: '#808080'
            }]
        },/*
        tooltip: {

PHP 代码

我的 PHP 代码有很多问题，因为我是创建图表的初学者。

<?php
    $purchases = $db->query("SELECT COUNT(id) AS num, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM purchases WHERE `date` LIKE '2015%' GROUP BY DATE_FORMAT(date, '%Y-%M') ORDER BY DATE_FORMAT(date, '%Y-%M') ASC");
    $sales = $db->query("SELECT COUNT(id) AS num, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM sales WHERE `date` LIKE '2015%' GROUP BY DATE_FORMAT(date, '%Y-%M') ORDER BY DATE_FORMAT(date, '%Y-%M') ASC");
    $transfers = $db->query("SELECT COUNT(id) AS num, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM transfers WHERE `date` LIKE '2015%' GROUP BY DATE_FORMAT(date, '%Y-%M') ORDER BY DATE_FORMAT(date, '%Y-%M') ASC");

    while($objP = $purchases->fetch(PDO::FETCH_OBJ))
    {
        if($objP->dataofmonth == "".date('Y')."-January")

            $decS = $objS->num;
        else
            $decS = 0;

    }
    while($objT = $transfers->fetch(PDO::FETCH_OBJ))
    {
        if($objT->dataofmonth == "".date('Y')."-January")
            $janT = $objT->num;

            $mayT = $objT->num;
        if($objT->dataofmonth == "".date('Y')."-June")
            $junT = $objT->num;
        if($objT->dataofmonth == "".date('Y')."-July")
            $julT = $objT->num;
        if($objT->dataofmonth == "".date('Y')."-August")
            $augT = $objT->num;

        if($objT->dataofmonth == "".date('Y')."-December")
            $decT = $objT->num;
    }
?>

在上面的 php 代码中，我试图将数据放入高图表代码的后续行但失败了。

{
    name: 'Sales',
    data: [<?=@$janS?>, <?=@$febS?>, <?=@$marS?>, <?=@$aprS?>, <?=@$mayS?>, <?=@$junS?>, <?=@$julS?>, <?=@$augS?>, <?=@$sepS?>, <?=@$octS?>, <?=@$novS?>, <?=@$decS?>]
}

如果我的目标和工作流程正确，您应该更换：

 while($objS = $sales->fetch(PDO::FETCH_OBJ))
    {
        if($objS->dataofmonth == "".date('Y')."-January")
            $janS = $objS->num;
        else
            $janS = 0;

        if($objS->dataofmonth == "".date('Y')."-February")
            $febS = $objS->num;
        else
            $febS = 0;

        if($objS->dataofmonth == "".date('Y')."-March")
            $marS = $objS->num;
        else
            $marS = 0;

        if($objS->dataofmonth == "".date('Y')."-April")
            $aprS = $objS->num;
        else
            $aprS = 0;

        if($objS->dataofmonth == "".date('Y')."-May")
            $mayS = $objS->num;
        else
            $mayS = 0;

        if($objS->dataofmonth == "".date('Y')."-June")
            $junS = $objS->num;
        else
            $junS = 0;

        if($objS->dataofmonth == "".date('Y')."-July")
            $julS = $objS->num;
        else
            $julS = 0;

        if($objS->dataofmonth == "".date('Y')."-August")
            $augS = $objS->num;
        else
            $augS = 0;

        if($objS->dataofmonth == "".date('Y')."-September")
            $sepS = $objS->num;
        else
            $sepS = 0;

        if($objS->dataofmonth == "".date('Y')."-October")
            $octS = $objS->num;
        else
            $octS = 0;

        if($objS->dataofmonth == "".date('Y')."-November")
            $novS = $objS->num;
        else
            $novS = 0;

        if($objS->dataofmonth == "".date('Y')."-December")
            $decS = $objS->num;
        else
            $decS = 0;

    }

至：

$salesArr = array_fill(1,12,0);
 while($objS = $sales->fetch(PDO::FETCH_OBJ))
    {
        if($objS->dataofmonth == "".date('Y')."-January")
            $salesArr[1] = $objS->num;
        if($objS->dataofmonth == "".date('Y')."-February")
            $salesArr[2] = $objS->num;
        if($objS->dataofmonth == "".date('Y')."-March")
            $salesArr[3] = $objS->num;
        if($objS->dataofmonth == "".date('Y')."-April")
            $salesArr[4] = $objS->num;
        if($objS->dataofmonth == "".date('Y')."-May")
            $salesArr[5] = $objS->num;
        if($objS->dataofmonth == "".date('Y')."-June")
            $salesArr[6] = $objS->num;
        if($objS->dataofmonth == "".date('Y')."-July")
            $salesArr[7] = $objS->num;
        if($objS->dataofmonth == "".date('Y')."-August")
            $salesArr[8] = $objS->num;
        if($objS->dataofmonth == "".date('Y')."-September")
            $salesArr[9] = $objS->num;
        if($objS->dataofmonth == "".date('Y')."-October")
            $salesArr[10] = $objS->num;
        if($objS->dataofmonth == "".date('Y')."-November")
            $salesArr[11] = $objS->num;
        if($objS->dataofmonth == "".date('Y')."-December")
            $salesArr[12] = $objS->num;

    }

并更改您的：

{
    name: 'Sales',
    data: [<?=@$janS?>, <?=@$febS?>, <?=@$marS?>, <?=@$aprS?>, <?=@$mayS?>, <?=@$junS?>, <?=@$julS?>, <?=@$augS?>, <?=@$sepS?>, <?=@$octS?>, <?=@$novS?>, <?=@$decS?>]
}

至：

{
    name: 'Sales',
    data: [<?=implode(',',$salesArr) ?>]
}

希望我的猜测是正确的并且对您有所帮助:-)
