Question

我正在编码此PHP应用程序，并且我编写的公共函数未返回任何错误而没有任何错误。使用var_dump($_POST);查看返回的内容时，我得到array(0) { }。我正在尝试为我的应用编写一个基本的通知系统，该系统将根据组ID以及会话中的用户是否已看到来加载后续消息。如果用户已经看到它，它将被存储在“ readsbaby”选项卡中，然后在第二次加载该函数时将其考虑在内。

尝试了不同的方法，但是都出现了混乱的错误。

型号：

public function get_follow_up_data($group_id)
{        

$servername = "localhost";
$username = "root";
$password = "";


// Create connection
$myConnection= mysqli_connect("$servername","$username","$password", 
"impetusb_bilal") or die ("could not connect to mysql");

    $sql="SELECT pk_followup_id,report_id,report_nature, group_id, created_date
    FROM users_follow_up
    WHERE DATE(created_date) > DATE_SUB(CURDATE(), INTERVAL 1 DAY) AND group_id = " . $this->session->userdata['user']['group_id'] . "  AND NOT EXISTS ( SELECT notification_id
               FROM readsbaby
               WHERE users_follow_up.pk_followup_id = readsbaby.notification_id AND users_follow_up.group_id = readsbaby.group_id  AND readsbaby.user_id = " . $this->session->userdata('id') . " AND users_follow_up.report_nature = readsbaby.notification_type
             ) 

      ";

$query=mysqli_query($myConnection, $sql) or die(mysqli_error($myConnection));

var_dump($_POST);


return ($query);




}

控制器：

public function show_followup_details( $id,$report_nature,$follow_up_id)

  $report_nature = str_replace ('%20', ' ', $report_nature);
  $this->session->set_userdata('page_title','Details');
