retrieving array as comma separated values in codeigniter - php

Question

I am using the below code to get the ids from the pr_users table and store it in pr_notification_table,but unable to store the values separated by comma into pr_notifications table. I want to store $notification_data['show_users'] as 1,2,3,4 etc so that notifications are sent to these ids. Its inserting NULL on executing this , I have attached table images also,
pr_notifications table is as below:
My controller code is:
if($data['rows'][0]['last_status'] == 'Accepted')
{
$ids= '22';
$data['success_message'] = $this->exit_common->send_notification_to_all_roles($ids);
echo "Success";
}
My model code is:
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

I think you have to get notification_id from pr_users table, and then use the following code for get notification_id comma seprated.Assume than your notification id array is :- $user_notification_ids_info
Now go with this code.
$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);
Now simply echo $notification_ids; it will return your comma seprated notification id.
It will helps you try this one.

Answer 2

You want to store $ids comma separated? then use implode().
$arr = array('Hello','World!','Beautiful','Day!');
echo implode(",",$arr);
I hope this will help.
