<div>Pesan kesalahan "Call to a member function row() on bool" berarti variabel $cek bukan merupakan objek. Hal ini disebabkan karena variabel $cek adalah hasil dari metode $this->model_app->cek_login(), yang mengembalikan nilai integer. Untuk mengatasi kesalahan ini, Anda perlu mengubah variabel $cek menjadi objek. Anda dapat melakukannya dengan menggunakan metode CI_DB_result::result_array(). Metode CI_DB_result::result_array() akan mengembalikan sebuah array objek, di mana setiap objek mewakili satu baris dalam database.<br><br>Berikut ini adalah kode yang telah diperbarui:<br><br><br></div><pre>function index() { if (isset($_POST['submit'])) { if ($this->input->post() && (strtolower($this->input->post('security_code')) == strtolower($this->session->userdata('mycaptcha')))) { $username = $this->input->post('a', TRUE); $password = hash("sha512", md5($this->input->post('b', TRUE))); $cek = $this->model_app->cek_login($username, $password, 'users'); $row = $cek->result_array(); $total = $cek->num_rows(); if ($total > 0) { $this->session->set_userdata('upload_image_file_manager', true); $this->session->set_userdata(array( 'username' => $row[0]['username'], 'level' => $row[0]['level'], 'id_session' => $row[0]['id_session'] )); redirect($this->uri->segment(1) .
