取日期如何獲取由過去的7天笨日期....

public function get_data() { 
     $this->db->select('*'); 
     $this->db->select_sum('total_sale'); 

$this->db->where('store_date BETWEEN CURDATE() - INTERVAL 7 DAY AND CURDATE()'); 
     $query = $this->db->get('one_month_report'); 
     if ($query->num_rows() > 0) { 
      return $query->result(); 
     } else { 
      return FALSE; 
     } 
    } 

Answer 1

如果您的數據庫正在將這些值存儲爲DATETIME或TIMESTAMP，則應該起作用。

$start_date = date("Y-m-d 00:00:00", strtotime("-1 week")); 

$end_date = date("Y-m-d 59:59:59"); 

$this->db->where("store_date >= '" . $start_date . "' AND store_date <= '" . $end_date . "'"); 

Answer 2

試試這個

public function get_data() 
{ 
    $query = $this->db->query("SELECT *, SUM(cast(REPLACE(total_sale, ',', '') as decimal(8,2))) 
           FROM one_month_report 
           WHERE store_date BETWEEN CURDATE() AND DATE(NOW()) - INTERVAL 7 DAY"); 
    $result= $query->result_array(); 

    if (empty($result)) { 
     echo "Empty result"; 
    } else { 
     return $result; 
    } 
} 

確保CURDATE()將返回日期

Answer 3

請試試這個：

$this->db->select('*'); 
$this->db->select_sum('total_sale'); 
$this->db->where('store_date BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW()'); 
$query = $this->db->get('one_month_report');
