我想要計算用戶在Codeignter中獲得的通知量。我正在比較每個用戶行中保存的時間戳記,這些記錄是上次檢查通知頁面時記錄的時間戳記,以及每個通知添加的時間。但是我得到一個數據庫錯誤:比較兩個時間戳Codigniter

SELECT * FROM (`notifications`) WHERE `user_id` = '1' AND `instigator_id` != '1' AND added <= 2014-11-04 10:17:00
文件名:/Users/true/Documents/Site/models/private/notifications_model.php
行號:152
通知控制器看起來像這
$data["user"] = $CI->Profile_model->get_public_profile_id($logged_user);
$count = $CI->notifications_model->get_notifications_count($data["user"][0]["notes_check"]);
型號:
public function get_notifications_count($time){
$this->db->from($this->notifications_table);
$this->db->where('user_id', $this->session->userdata("id", 0));
$this->db->where('instigator_id !=', $this->session->userdata("id", 0));
$this->db->where('added <= '.$time, '', false);
$query = $this->db->get();
$results = $query->result_array();
return count($results);
}

@MonkeyZeusTried with $ this-> db-> where('added <='。「$ time」,'',false);並仍然出現錯誤 – Matt 2014-11-05 21:57:04
您是否閱讀過文檔? '$ this-> db-> where('some_field','some value');' – MonkeyZeus 2014-11-05 22:00:02
