If there are rows affected in database, then do this

I have this delete function in my model. When you press the delete button, it will subtract the number of total notes from the total notes column in my database. For eg. if you had 200 notes, and you deleted one of them, it will be 199 notes AND the note will be deleted from the database.

My code:

PHP Code:
public function entry_delete($pid) {


$whereConditions = array('pid' => $pid'uid' => $uid);

        if (
$this->db->affected_rows() == 0) {
$sql_entry "UPDATE users set total_entry = total_entry - 1 WHERE uid = $uid";
        } else {

But this doesn't work. I don't know why but when I press the delete button from my view, it will delete it from the database AND subtract -1 from my total_entry table. However, if I comment out the
PHP Code:
It will still subtract 1 from the total_entry.

How do I fix this? Thanks.

Hi Taylor,

You can try below code.

if ($this->db->affected_rows() > 0)
