コメントに記載されているいくつかのケースをチェックするために、次のコードを使用します。残念ながら、ページの読み込み速度が低下しています。機能を向上させて適切に使用するために、あなたは何を提案しますか、私は何をしますか?
function insert() {
if ($this - > session - > userdata('logged_in')) { //This is for test whether the user is logged in or not?
if ($this - > siran - > access_level_active()) { //This is because the user name manager is active or not?
if ($this - > siran - > access_level('1', '5')) { //This is for whether or not permission to access this page?
if($_POST){
$this - > load - > view('admin/onepage');
}else{
$this->session->set_flashdata('message_p', $this->lang->line('nopost'));
redirect($this->session->userdata('previous_page'));
}
} else {
$this - > session - > set_flashdata('message', $this - > lang - > line('notaccess'));
redirect($this - > session - > userdata('previous_page'));
}
} else {
$this - > session - > set_flashdata('message', $this - > lang - > line('noactive'));
redirect('login', 'refresh');
