问题 I have query that runs in the controller: $data['query'] = $this->Member->select_sql($id); $this->load->view('myform'); and then outputs data in the view: foreach ($query->result() as $row): echo $row->post_title; echo $row->post_user_id; endforeach; So this outputs me a list of posts made by a user.

问题 I got a strange problem, my current pagination link is not highlighted the pagination urls I made looks like: site.com/list/50/?some=value Everything is working great, but the current pagination link in view is not highlighted. I checked CSS and it's ok, the problem comes from the library I guess. This is my code. I can't see anything wrong in here: $pagination['base_url'] = site_url('asd'); if($_SERVER['QUERY_STRING'] !==''){ $pagination['suffix'] = '/?'.$_SERVER['QUERY_STRING']; }

问题 Currently I use CodeIgniter with regular queries, i.e.: $sql = " SELECT * FROM my_table WHERE item_id > 1 "; $q = $this->db->query($sql); I have started looking into ActiveRecord, and it does look nice, and has the advantage of the query being built regardless of which database driver is used - however, I strictly use a single database type per project in general, so this is not really a benefit for me. I found that regular queries (as I have in my example) are more readable and easier

问题 I am trying to figure out why Codeigniter is inserting 2 times the same row in my Database. I'm using PDO as interface for mySQL. I was debugging it and I am sure the function bellow is not being executed two times. It happens in a particular case, if the two foreache's don't run because the array is empty, but if one of them runs the error doesn't happen. ` public function save_all() //save all information with the launched flag FALSE { include(database_vars_url()); try { $this->add_new
