php - 谷歌折线图不使用 PHP 显示 MySQL 查询

问题描述

嗨 StackOverflow 社区，我正在努力在 Google 折线图中使用 PHP 显示 MySQL 查询。问题是折线图没有显示。我会感谢任何能够为我指明正确方向的人。以下 MySQL 查询是我试图在折线图中表示的内容：

SELECT
    DATE(`VISIT_TIME`) AS `Date`,
    SUM(IF(HOUR(`VISIT_TIME`) = 0,
    1,
    0)) AS `TwelveAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 1,
    1,
    0)) AS `OneAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 2,
    1,
    0)) AS `TwoAM`, 
    SUM(IF(HOUR(`VISIT_TIME`) = 3,
    1,
    0)) AS `ThreeAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 4,
    1,
    0)) AS `FourAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 5,
    1,
    0)) AS `FiveAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 6,
    1,

    SUM(IF(HOUR(`VISIT_TIME`) = 7,
    1,
    0)) AS `SevenAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 8,
    1,
    0)) AS `EightAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 9,
    1,
    0)) AS `NineAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 10,
    1,
    0)) AS `TenAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 11,
    1,
    0)) AS `ElevenAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 12,
    1,
    0)) AS `TwelvePM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 13,
    1,
    0)) AS `OnePM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 14,
    1,
    0)) AS `TwoPM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 15,
    1,

    SUM(IF(HOUR(`VISIT_TIME`) = 16,
    1,

    SUM(IF(HOUR(`VISIT_TIME`) = 17,
    1,
    0)) AS `FivePM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 18,
    1,
    0)) AS `SixPM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 19,
    1,
    0)) AS `SevenPM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 20,
    1,
    0)) AS `EightPM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 21,
    1,
    0)) AS `NinePM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 22,
    1,
    0)) AS `TenPM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 23,
    1,
    0)) AS `ElevenPM`
FROM
    `jurl_analytics`
WHERE
    `URL_ID` = 'westonsupermare'
GROUP BY
    DATE(`VISIT_TIME`)

以下查询显示过去 7 天每小时的请求数。 PHPMyAdmin 中查询的输出

我从 WhiteHat 的回答中得到了什么： 在此处输入图像描述

标签： phphtmlmysqlchartsgoogle-visualization

解决方案

这里有几个问题。

首先，列标题中有 25 个值...

['Date', 'TwelveAM', 'OneAM', 'TwoAM', ...

但是行数据中有 26 个值...

echo "['".$result['Date']."',".$result['TwelveAM']."','".$result['OneAM']."' ...

有两个TwelvePM值，我们将在最后删除一个，
因为它与最后一列标题不匹配。

接下来，正如您在评论中提到的，逗号和撇号
的数量可能会令人困惑。 这是您不应尝试手动构建 JSON 的原因之一。

相反，在 PHP 中构建数组，然后在写入页面时对 JSON 进行编码。

<?php
  $data = array();
  $data[] = ['Date', 'TwelveAM', 'OneAM', 'TwoAM', 'ThreeAM', 'FourAM', 'FiveAM', 'SixAM', '7AM', '8AM', '9AM', '10AM', '11AM', '12PM', '1PM', '2PM', '3PM', '4PM', '5PM', '6PM', '7PM', '8PM', '9PM', '10PM', '11PM'];

  $fire = mysqli_query($connect, $sevenDaysHours);
  while($result = mysqli_fetch_assoc($fire))
  {
    $data[] = [$result['Date'], $result['TwelveAM'], $result['OneAM'], $result['TwoAM'], $result['ThreeAM'], $result['FourAM'], $result['FiveAM'], $result['SixAM'], $result['SevenAM'], $result['EightAM'], $result['NineAM'], $result['TenAM'], $result['ElevenAM'], $result['TwelvePM'], $result['OnePM'], $result['TwoPM'], $result['ThreePM'], $result['FourPM'], $result['FivePM'], $result['SixPM'], $result['SevenPM'], $result['EightPM'], $result['NinePM'], $result['TenPM'], $result['ElevenPM']];
  }
?>

google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
  var data = google.visualization.arrayToDataTable(<?php echo json_encode($data); ?>);

  var options = {
    title: 'Company Performance',
    curveType: 'function',
    legend: { position: 'bottom' }
  };

  var chart = new google.visualization.LineChart(document.getElementById('curve_chart'));

  chart.draw(data, options);
}

这是您要查找的部分...

  $connect = mysqli_connect($server,$username,$password,$database);

如果数字值是来自 PHP 的字符串，
则尝试将JSON_NUMERIC_CHECK参数添加到编码语句。

<?php echo json_encode($data, JSON_NUMERIC_CHECK); ?>

让我们将 JSON 数据分配给它自己的变量。
然后我们可以将结果发送到控制台进行检查。
如果它仍然不起作用，请从控制台分享一个示例。

<?php
  $data = array();
  $data[] = ['Date', 'TwelveAM', 'OneAM', 'TwoAM', 'ThreeAM', 'FourAM', 'FiveAM', 'SixAM', '7AM', '8AM', '9AM', '10AM', '11AM', '12PM', '1PM', '2PM', '3PM', '4PM', '5PM', '6PM', '7PM', '8PM', '9PM', '10PM', '11PM'];

  $fire = mysqli_query($connect, $sevenDaysHours);
  while($result = mysqli_fetch_assoc($fire))
  {
    $data[] = [$result['Date'], $result['TwelveAM'], $result['OneAM'], $result['TwoAM'], $result['ThreeAM'], $result['FourAM'], $result['FiveAM'], $result['SixAM'], $result['SevenAM'], $result['EightAM'], $result['NineAM'], $result['TenAM'], $result['ElevenAM'], $result['TwelvePM'], $result['OnePM'], $result['TwoPM'], $result['ThreePM'], $result['FourPM'], $result['FivePM'], $result['SixPM'], $result['SevenPM'], $result['EightPM'], $result['NinePM'], $result['TenPM'], $result['ElevenPM']];
  }
?>

var jsonData = <?php echo json_encode($data, JSON_NUMERIC_CHECK); ?>;
console.log(JSON.stringify(jsonData));

google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
  var data = google.visualization.arrayToDataTable(jsonData);

  var options = {
    title: 'Company Performance',
    curveType: 'function',
    legend: { position: 'bottom' }
  };

  var chart = new google.visualization.LineChart(document.getElementById('curve_chart'));

  chart.draw(data, options);
}

为了获得所需的图表，
我们需要将列交换为行，反之亦然。
这很可能很难通过更改查询来实现。
但是我们可以很容易地在 JavaScript 中创建一个新的数据表。

所以，几乎一切都保持不变。
除了我们将添加以下例程来创建一个新的数据表，
并交换列和行。
然后使用新的数据表绘制图表。

var jsonData = <?php echo json_encode($data, JSON_NUMERIC_CHECK); ?>;

google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
  var data = google.visualization.arrayToDataTable(jsonData);

  // create new data table with columns and rows swapped
  var dataHours = new google.visualization.DataTable();
  dataHours.addColumn('number', 'Hour');
  for (var row = 0; row < data.getNumberOfRows(); row++) {
    var dateColumn = dataHours.addColumn('number', data.getValue(row, 0));
    for (var col = 1; col < data.getNumberOfColumns(); col++) {
      var dateRow = dataHours.addRow();
      dataHours.setValue(dateRow, 0, col);
      dataHours.setValue(dateRow, dateColumn, data.getValue(row, col));
    }
  }

  var options = {
    title: 'Company Performance',
    curveType: 'function',
    legend: { position: 'bottom' }
  };

  var chart = new google.visualization.LineChart(document.getElementById('curve_chart'));

  chart.draw(dataHours, options);  // <-- draw chart with new data table
}

以下是一个工作示例，显示了交换之前和之后...

google.charts.load('current', {
  packages:['corechart']
}).then(function () {
  var data = google.visualization.arrayToDataTable([
    ['Date', 'TwelveAM', 'OneAM', 'TwoAM', 'ThreeAM', 'FourAM', 'FiveAM', 'SixAM', '7AM', '8AM', '9AM', '10AM', '11AM', '12PM', '1PM', '2PM', '3PM', '4PM', '5PM', '6PM', '7PM', '8PM', '9PM', '10PM', '11PM'],
    ['2020-08-14', 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25],
    ['2020-08-15', 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50],
    ['2020-08-16', 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75],
    ['2020-08-17', 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100]
  ]);

  // create new data table with columns and rows swapped  
  var dataHours = new google.visualization.DataTable();
  dataHours.addColumn('number', 'Hour');
  for (var row = 0; row < data.getNumberOfRows(); row++) {
    var dateColumn = dataHours.addColumn('number', data.getValue(row, 0));
    for (var col = 1; col < data.getNumberOfColumns(); col++) {
      var dateRow = dataHours.addRow();
      dataHours.setValue(dateRow, 0, col);
      dataHours.setValue(dateRow, dateColumn, data.getValue(row, col));
    }
  }

  var options = {
    chartArea: {
      left: 64,
      top: 48,
      right: 32,
      bottom: 64,
      height: '100%',
      width: '100%'
    },
    height: '100%',
    legend: {
      alignment: 'center',
      position: 'bottom'
    },
    width: '100%'
  };

  var chartBefore = new google.visualization.LineChart(document.getElementById('chart_before'));
  chartBefore.draw(data, options);

  var chartAfter = new google.visualization.LineChart(document.getElementById('chart_after'));
  chartAfter.draw(dataHours, options);
});
.chart {
  height: 260px;
}
