如何计算所有条件为 Date Now
How to Count all with condition Date Now
我尝试用日期条件计算我网站中的所有行,但我不知道为什么我的代码仍然不起作用。我尝试在我的专栏前面添加(日期)(created_at),但结果:
error "Message: Call to a member function num_rows() on boolean"
这是我的代码:
public function hitungPerbaikan()
{
$date = new DateTime('now');
$curr_date = $date->format('Y-m-d');
$this->db->where('update_at', $curr_date);
$this->db->where('status >=', '2');
$this->db->from('tbl_kerusakan');
return $this->db->count_all_results();
}
感谢您的建议,它真的帮助我弄明白了,这是我现在的代码
public function hitungPerbaikan()
{
$date = new DateTime('now');
$curr_date = $date->format('ymd');
$this->db->where('update_at>=', $curr_date);
$this->db->where('status >=', '2');
$this->db->from('tbl_kerusakan');
$db_result = $this->db->get();
return $db_result->num_rows();
}
