Answer 1

If you want to get single row from database please use $q->row_object() or $q->row_array() . Then you don't need to use foreach on view. Please see below example:-

Your Modal

public function getall($seid)
{
    $this->db->select('uid','name','details','img');
    $this->db->where("email",$seid);
    $q=$this->db->get('tbl_reg');
    return $q->row_array();
}

On your View

<?php   echo "username:".$row['name']; ?> 
<br/>
<?php echo "email:" .$row['email'];?>
<br/>
<?php echo "user id:" .$row['uid'];?>
<?php echo "Details:".$row['details'];?>
<img src="<?php echo $row['img'] ;?>"  style="width:104px;height:142px"; />

Answer 2

modify your model to use the following:

public function getall($seid)
{
    $this->db->select('uid','name','details','img');
    $this->db->where("email",$seid);
    $q=$this->db->get('tbl_reg');

    return $q->result_array();
}

Answer 3

In controller, add the user details in the following manner,

public function view()
    {
    $seid=$this->session->userdata('user_id');
    $data['result']=$this->search_model->getall($seid);
    $newdata = array(
               'username'  => <USERNAME>,
               'email'     => <MAILID>,
                ...........
               'logged_in' => TRUE
           );

    $this->session->set_userdata($newdata);
    $this->load->view('pagination_view',$data);
}
