so here is my model codes:

public function GetId()
{
    $this->db->select('count(*) as total');
    $this->db->from($this->table);
    $this->db->where('dibaca', null);
    $query = $this->db->get();
    return $query->result_array();
}

and this is my code in html:

<?= $DataId['total']; ?>

i already call the function to my controller as DataId, and i get error that Undefined array key "total"

can you guys tell me what is wrong in it?

CodePudding user response：

Replace the result_array() at the model with

num_rows() 

and you can delete ['total'] from your code in html, or like this:

<?= $DataId; ?>

Some untested advice:

Your model can be refined to:

public function countNullDibaca(): int
{
    return $this->db
        ->where("dibaca", null)
        ->count_all_results($this->table);
}

Your controller should call for the model data and pass it to the view.

function myController(): void
{
    $this->load->model('my_model', 'MyModel');
    $this->load->view(
        'my_view',
        ['total' => $this->MyModel->countNullDibaca()]
    );
}

Finally, your view can access the variable that associates with the first-level key in the passed in array.

<?= $total; ?>

Here is a related post which speaks on passing data from the controller to the view.
