[FIXED] Why doesn't CI convert count statement to an array?

Issue

I'm trying to make it so that you can view the number of rows of something on my website, I converted the result into an array and then foreached it in the view, yet it calls the argument invalid.

As I said, I've tried the usual, passing on the data from the model to the controller and then to the view. I tried returning $query->num_rows(); as well as a count_all_results back to the controller array for it to be used in the view, both are invalid.

controller.php

  $this->load->model('Main');
  $data = array(
    'getapps' => $this->Main->countapps()
  );
  $this->load->view('header', $data);

view.php

<?php foreach($getapps as $apps) {
?>

<a href="http://localhost/Dir/index.php/Controller/Apps" class="a-m" id="a-m-id">apps <strong><?php echo $apps; ?></strong></a>

<?php }
?>

model.php

public function countapps() {

$this->db->where('usedby', $_SESSION['uid']);
$this->db->get_where('apps', 'appstatus', 'Used');
$stmt = $this->db->count_all_results();

  return $stmt;
}

What I expect to happen is for the view to display the number of rows, instead it tells me that the foreach argument is invalidly supplied.

Solution

In CI $this->db->count_all_results() substitutes $this->db->get() in a database query. Therefore you cannot use $this->db->get_where() and $this->db->count_all_results() at the same time, use num_rows() instead.

write your model function like this:

public function countapps() {

 $query=$this->db->where('usedby', $_SESSION['uid'])
                 ->get_where('apps', 'appstatus', 'Used');
  $stmt = $query->num_rows();

  return $stmt;
}

you could change in your controller to a shorter:

$data['getapps'] => $this->Main->countapps();

Then in your view, you don't need to use foreach() as $data['getapps'] is not an array but a number. You can output it in the view simply like

echo $getapps;
