    $this->load->library('session');
    $this->load->helper(array('form', 'url'));
    $this->load->model('M_Data');
}

public function save_physical() {
    if($this->session->userdata('login')){
        $session = $this->session->userdata('login');
        $get = $this->uri->uri_to_assoc(1);
        $atlet = $get['atlet'];
        $current_dttm = date('Y-m-d');

        $nama_komponen  = $_POST['input_name'];
        $nilai_komponen = $_POST['input_nilai'];

        $data = array(

}
}

Answer 1

In codeigniter Controller name and controller file name should only first letter Capital

change file name to "atlet_goal.php" and controller name to "Atlet_goal"

or use url like

http://awd.esy.es/index.php/atlet_Goal/save_physical/atlet/fashah
