Question

我从db获取日期以在下拉菜单中显示日期。它基于id显示。我想根据日期对数据进行排序。我现在按以下顺序获取日期：

  Saturday, March 25
  Saturday, April 15
  Wednesday, April 5
  Saturday, May 6
  Saturday, April 29
  Wednesday, May 10
  Saturday, May 20

我需要以下顺序的数据：

  Saturday, March 25
  Wednesday, April 5
  Saturday, April 15
  Saturday, April 29
  Saturday, May 6
  Wednesday, May 10
  Saturday, May 20

代码

   $dates = \Drupal::service('custom_forms.custom_forms_service')->getDates();
   $datesObj = array("" =>"- Select -");
   foreach($dates as $date){
        $datesObj[$date->id] = $date->date;
    echo "<pre>";print_r($datesObj[$date->id]);
     }
     exit;

Answer 1

SELECT id, name, form_id, DATE(updated_at) as date
  FROM wp_frm_items
  WHERE user_id = 11 && form_id=9
  ORDER BY updated_at DESC,id ASC

这将首先按日期对记录进行排序，然后按名称对记录进行排序 More detail

使用php按日期值排序
