Question

Is there a way to increment a views table for some content, or if it doesn’t exist add the first view without running 2 queries. Here’s my current code that works.

function increment_views($id = null) {

  if ($id !== NULL) {
    $record = array('id' => $id, 'views' => 'views+1');
    // check exists
    $query = $this->db->get_where('views', array('id' => $id), 1, 0);
    if ($query->num_rows() == 0) {
      // if !exists, insert
        $db_view_data = array(
        'id' => $id,
        'views' => '1'
        );
        $this->db->insert('views', $db_view_data);
    } else {
      // A record does exist, update it.
      $this->db->where('id', $id);
      $this->db->set('views', 'views+1', false);
      $this->db->update('views');

    }
    // check it worked
    if ($this->db->affected_rows() > 0) {
      return true;
    }
    return false;
  }
  return false;
}

You can achieve this using on duplicate key as follows :

$query = "INSERT into views(id,views)values($id,1) on DUPLICATE KEY UPDATE views=views+1;

Hope this helps 🙂
