Question

我使用下面的代码从pr_users表中获取id并将其存储在pr_notification_table中，但无法将用逗号分隔的值存储到pr_notifications表中。我想将$ notification_data [＆＃39; show_users＆＃39;]存储为1,2,3,4等，以便将通知发送到这些ID。它在执行时插入NULL，我也附加了表格图像，

pr_notifications表如下：

我的控制器代码是：

＆＃13;

＆＃13;

if($data['rows'][0]['last_status'] == 'Accepted')
			{
				$ids= '22';
			$data['success_message'] = $this->exit_common->send_notification_to_all_roles($ids);
			echo "Success";
			
			}

＆＃13;

＆＃13;

＆＃13;

我的型号代码是：

＆＃13;

＆＃13;

function send_notification_to_all_roles($ids)
		{
			
			global $USER;
			$post_arr = $this->input->post();
			 $this->db->select('g.*,id');
		$this->db->from('pr_users as g'); 
		 $this->db->where('userroleid', $ids); 
		//$this->db->join($this->myTables['pr_users_details'].' as ud','ud.userid = g.userid');
		//$this->db->join('pr_users_details as ud','ud.userid = g.userids');
		
	/*	$this->db->join($this->myTables['users_details'].' as ud','ud.userid = g.userid');
		$this->db->join('pr_resignation_type as gt','gt.id = g.sr_type');*/
		$query=$this->db->get();	
		
		$return	= $query->result_array();
		$arr = explode(',',$return);
		foreach($arr as $num)
		{
			echo $num."<br>";
			}
		print_r($num);
		die;
		
			$manager_id = $this->get_value_by_id('managerid','users',$this->session->userdata('admin_id'));
			$user_id='1';
					$v_memberid = $manager_id . "," . $user_id;
						//$manager_id = $this->get_value_by_id('managerid','users',$this->session->userdata('admin_id'));
					$notification_data['ref_table']			=	'pr_resignation_requests';	
					$notification_data['ref_id']			=	'1';
					$notification_data['modifier_id']		=	$USER->id;
					$notification_data['show_users']		=	$num;
					$notification_data['notification_descr']=	"A new Job has been created" ;//$manager_id;
					$notification_data['notification_text']	=	"A new Job has been created";
					$notification_data['added_on']			=	date("Y-m-d H:i:s");
					$notification_data['url']				=	'exits';
					$notification_data['uurl']				=	'exits';
					$this->db->insert($this->myTables['notifications'],$notification_data);
					return 'Resignation Request submitted successfully';
		}

Answer 1

我认为您必须从pr_users表中获取notification_id，然后使用以下代码获取get notification_id逗号seprated.Assume比您的通知ID数组： - $user_notification_ids_info 现在使用此代码。

$ids = ''; $notification_ids = '';
for($i=0; $i<count($user_notification_ids_info); $i++)
{ 
$ids = $user_notification_ids_info[$i]['notification_id'];
$notification_ids.= $ids.", ";
}
$notification_ids = substr(trim($notification_ids), 0, -1);

现在只需echo $notification_ids;它就会返回逗号分隔的通知ID。 它会帮助你尝试这个。

Answer 2

你想以逗号分隔存储$ ids吗？然后使用implode（）。

$ arr = array（＆＃39; Hello＆＃39;，＆＃39; World！＆＃39;，＆＃39; Beautiful＆＃39;，＆＃39; Day！＆＃39;）; echo implode（＆＃34;，＆＃34;，$ arr）;

我希望这会有所帮助。
