我如何添加选项以显示上个月的统计信息。

PHP

public function chart() {
    $this->load->language('common/home');

    $data = array();

    $data['order'] = array();
    $data['customer'] = array();
    $data['xaxis'] = array();

    $data['customer']['label'] = $this->language->get('text_customer');

    if (isset($this->request->get['range'])) {
        $range = $this->request->get['range'];
    } else {
        $range = 'month';
    }

    switch ($range) {
        case 'day':
            for ($i = 0; $i < 24; $i++) {

Answer 1

创建新的HTML选项

    <option value="last_month">Last Month</option>

然后为last_month选项添加一个新的switch case。您可以通过将月份案例从案例“月份”行复制到休息时间来完成此操作;。

在for循环更改日期（'t'）中：

    date('t', strtotime(date('Y-m', strtotime('-1 month')).'-01'))

这将允许您获得最后几个月的天数，然后您应该更改的最后一位将是$ date var。与上述类似：

    $date = date('Y-m', strtotime('-1 month')).'-'.$i;

这可以让您查看上个月的所有统计数据。
