Opencart儀表板顯示上個月的統計信息

Question

我如何添加選項以顯示上個月的統計信息。

PHP

    $this->load->language('common/home'); 

    $data = array();

    switch ($range) {

Answer 1

創建一個新的HTML選項

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

然後爲您的last_month選項添加一個新的開關盒。您可以通過將案例'月份'行中的月份案例複製到中斷來執行此操作。

在for循環更改日期（「T」）於：

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

這將讓你得到最後一個月的天數，那麼你應該有改變的最後一位將是$日期變種。以類似的方式與上述：

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

這應該允許您查看所有您的上個月的統計數據。
