I need help Select Sum in codeigniter - codeigniter

Question

I need help to help me correct my php function in codeigniter.
I have a database; I want addirionner all values ​of " from_user_id ".
Check data
I use this sql to get the desired result.
SELECT SUM(kiff_envoi+kiff_recu+visite_recu+profile_visite+da_recu+da_envoi+topic_poster+repon_topic+conv_envoi+conv_recu) AS total_stats FROM score WHERE from_user_id = ?
In codeingniter I​ use this function.
It allows me to check if " from_user_id " exists, if it exists, we calculate the total different tables and we update the result in " total_stats ". If " from_user_id " does not exist, create it.
But my function does not return me the right result.
I had to make a big mistake but I do not know where!
Does someone could help me please.
public function count_tout_stats($user_id) //total des stats
{
$this->db->select_sum(conv_recu, conv_envoi, repon_topic, etc...);
$query = $this->db->from('score');
$this->db->where('from_user_id', $user_id);
$total_stats = $this->db->count_all_results();
if ($this->ttl_stats_score($user_id) > 0) // Check if exists
{
$data = array(
'total_stats' => $total_stats
);
$this->db->where('from_user_id', $user_id);
$this->db->update('score', $data);
}
else
{
$data = array(
'from_user_id' => $user_id,
'total_stats' => $total_stats
);
$this->db->insert('score', $data);
}
return $total_stats;
}
public function ttl_stats_score($user_id)
{
$this->db->where('from_user_id', $user_id);
$this->db->from('score');
return $this->db->count_all_results();
}
Thank you in advance for your assistance

You can try this:
$this->db->select('(kiff_envoi+kiff_recu+visite_recu+profile_visite+da_recu+da_envoi+topic_poster+repon_topic+conv_envoi+conv_recu) as total_stats');
$this->db->from('score');
$this->db->where('from_user_id', $user_id);
$result = $this->db->get()->row_array();
print_r($result);
You will get your result
