我正在尝试使用PHP& amp;创建Google时间线图表MySQL到目前为止没有任何成功。所以经过无数个小时的努力,到目前为止我已经做到了这一点:
首先,我尝试使用PHP创建json(我相信我在这里错过了一些东西) PHP
try {
$db = connectPDO();
$result = $db->query("SELECT naziv_plan AS name,
objava_odluke AS start_date,
datum_stupanja_glasnika AS end_date
FROM ispu_plan
WHERE datum_donosenja_plana
BETWEEN '2014-01-01'
AND CURDATE()
ORDER BY datum_donosenja_plana ASC");
$rows = array();
$table = array();
$table['cols'] = array(
array('label' => 'Godina', 'type' => 'string'),
array('label' => 'Odluka', 'type' => 'number'),
array('label' => 'glasnik', 'type' => 'number')
);
foreach($result as $r) {
$temp = array();
$temp[] = array('v' => (string) $r['naziv_plan']);
$temp[] = array('v' => (int) $r['objava_odluke']);
$temp[] = array('v' => (int) $r['datum_stupanja_glasnika']);
$rows[] = array('c' => $temp);
}
$table['rows'] = $rows;
$jsonTable = json_encode($table,JSON_NUMERIC_CHECK);
} catch(PDOException $e) {
echo 'ERROR: ' . $e->getMessage();
}
使用这段代码,我得到了这个JSON(它有效,用JSONLint检查)但是,我发现了一些不寻常的格式,甚至在JSON_NUMERIC_CHECK
之后
{"cols":[{"label":"Godina","type":"string"},{"label":"Odluka","type":"number"},{"label":"glasnik","type":"number"}],"rows":[{"c":[{"v":"Stambenog susjedstva - Stubi\u010dki Trnac - I.ID"},{"v":2014},{"v":2014}]},{"c":[{"v":"Prostorni plan ure\u0111enja Grada Krapine - IV. ID"},{"v":2013},{"v":2015}]},{"c":[{"v":"Prostorni plan ure\u0111enja Grada Donja Stubica - I ID"},{"v":2014},{"v":2015}]},{"c":[{"v":"Generalni urbanisti\u010dki plan Grada Krapine - V.ID"},{"v":2015},{"v":2016}]}]}
这是JS:
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var container = document.getElementById('timeline');
var chart = new google.visualization.Timeline(container);
var data = new google.visualization.DataTable(<?php echo $jsonTable;?>);
chart.draw(data);
运行整个代码块后,我收到此错误
无法读取未定义的属性'v'
PHP代码有问题吗? 1.可能日期格式有问题吗?
当我运行SQL时,我会得到类似这样的内容(例如:)
+-----------+------------------+-----------------+
| name| | start_date | end_Date |
+-----------+------------------+-----------------+
| example_1 | 2014-06-06 | 2014-12-27 |
| example_1 | 2013-12-31 | 2015-06-07 |
| example_1 | 2016-06-06 | 2015-12-31 |
+-----------+------------------+-----------------+
* 我想得到这样的东西: https://jsfiddle.net/api/post/library/pure/
所以,我设法修复了一些已解决的问题: 首先,使用奇怪格式化的JSON的问题,用 JSON_UNESCAPED_UNICODE
修复所以,而不是这段代码:
$jsonTable = json_encode($table,JSON_NUMERIC_CHECK);
我用过这个:
$jsonTable = json_encode($table,JSON_UNESCAPED_UNICODE);
在时间轴上注意我已经设法成功渲染时间线图表,但是在x轴上,而不是年份和日期,它显示了我的小时数。我相信在从查询转换为json时我错过了一些东西。 (如下图所示)
我使用了这段PHP代码:
try {
$db = connectPDO();
$result = $db->query("SELECT naziv_plan, objava_odluke, datum_stupanja_glasnika
FROM ispu_plan
WHERE datum_donosenja_plana
BETWEEN '2014-01-01'
AND CURDATE()
ORDER BY datum_donosenja_plana ASC");
$rows = array();
$table = array();
$table['cols'] = array(
array('label' => 'Naziv plana', 'type' => 'string'),
array('label' => 'Odluka', 'type' => 'datetime'),
array('label' => 'glasnik', 'type' => 'datetime')
);
foreach($result as $r) {
$temp = array();
$temp[] = array('v' => (string) $r['naziv_plan']);
$temp[] = array('v' => (int) strtotime($r['objava_odluke']));
$temp[] = array('v' => (int) strtotime($r['datum_stupanja_glasnika']));
$rows[] = array('c' => $temp);
}
$table['rows'] = $rows;
$jsonTable = json_encode($table,JSON_UNESCAPED_UNICODE);
} catch(PDOException $e) {
echo 'ERROR: ' . $e->getMessage();
}
在JSON中我得到类似1402005600
这样的开始日期,在我的表中格式化为2014-06-06
,我相信我需要得到类似2014, 6, 6
的内容才能正确渲染和计算时间线图表。
请帮助解决我一生的危机:)
使用白帽的知识和方向我觉得我距离最近让这种憎恶更近了:)同时,使用WhiteHat提供的方向和代码我创建了这个:
$rows = array();
$table = array();
$table['cols'] = array(
array('label' => 'Godina', 'type' => 'string'),
array('label' => 'Odluka', 'type' => 'date'),
array('label' => 'glasnik', 'type' => 'date')
);
while ($row = $result->fetch(PDO::FETCH_ASSOC)){
$date1 = new DateTime();
$date2 = "Date(".date_format($date1, 'Y').", ".((int) date_format($date1, 'm') - 1).", ".date_format($date1, 'd').")";
$temp = array();
$temp[] = array('v' => (string) $row['naziv_plan']);
$temp[] = array('v' => (string) $date2);
$temp[] = array('v' => (string) $date2);
$rows[] = array('c' => $temp);
}
$table['rows'] = $rows;
$jsonTable = json_encode($table,JSON_NUMERIC_CHECK);
json的输出是这样的:
{"cols":[{"label":"Godina","type":"string"},{"label":"Odluka","type":"date"},{"label":"glasnik","type":"date"}],"rows":[{"c":[{"v":"Stambenog susjedstva - Stubi\u010dki Trnac - I.ID"},{"v":"Date(2016, 8, 30)"},{"v":"Date(2016, 8, 30)"}]},{"c":[{"v":"Prostorni plan ure\u0111enja Grada Krapine - IV. ID"},{"v":"Date(2016, 8, 30)"},{"v":"Date(2016, 8, 30)"}]},{"c":[{"v":"Prostorni plan ure\u0111enja Grada Donja Stubica - I ID"},{"v":"Date(2016, 8, 30)"},{"v":"Date(2016, 8, 30)"}]},{"c":[{"v":"Generalni urbanisti\u010dki plan Grada Krapine - V.ID"},{"v":"Date(2016, 8, 30)"},{"v":"Date(2016, 8, 30)"}]}]}
我得到时间表,但没有线:(
这样的事情:
这两个错误:
预期数字,“MNaN,0LNaN,40.992
错误:属性x:预期长度,“NaN”
好的,我相信我已经以某种方式管理,而且它有效。这是下面的代码,希望它可以帮助某人。再次感谢WhiteHat:)
