codeigniter count_all_results

Have you read up on https://www.codeigniter.com/userguide2/database/active_record.html#caching ?

I see you are trying to do some pagination where you need the "real" total results and at the same time limiting.

This is my practice in most of my codes I do in CI.

    $this->db->start_cache();

    // All your conditions without limit
    $this->db->from();
    $this->db->where(); // and etc...
    $this->db->stop_cache();

    $total_rows = $this->db->count_all_results(); // This will get the real total rows

    // Limit the rows now so to return per page result
    $this->db->limit($per_page, $offset);
    $result = $this->db->get();

    return array(
        'total_rows' => $total_rows,
        'result'     => $result,
    ); // Return this back to the controller.

I typed the codes above without testing but it should work something like this. I do this in all of my projects.

$this->db->count_all_results() replaces $this->db->get() in a database call.

I.E. you can call either count_all_results() or get(), but not both.

You need to do two seperate active record calls. One to assign the results #, and one to get the actual results.

Something like this for the count:

$this->db->select('id');
$this->db->from('table');
$this->db->where($your_conditions);
$num_results = $this->db->count_all_results();

And for the actual query (which you should already have):

$this->db->select($your_columns);
$this->db->from('table');
$this->db->where($your_conditions);
$this->db->limit($limit);
$query = $this->db->get();

You dont actually have to have the from either, you can include the table name in the count_all_results like so.

$this->db->count_all_results('table_name');

Count first with no_reset_flag.

$this->db->count_all_results('', FALSE);
$rows = $this->db->get()->result_array();
