// 登陆控制 function check_login($session) { $data = $session->userdata('admin'); $cookie_login = get_cookie('cookie_login'); $login_name = get_cookie('login_name'); if (empty($data)) { if ($cookie_login == md5('maoriaty')) { $session->set_userdata('admin', ['username' => $login_name]); redirect('/recentimgtext'); } redirect('/login'); } }
登陆方法控制，如：
// 修改图文 public function modimgtext() { check_login($this->session); $imgtextid = $this->input->get('imgtextid'); $template = $this->db->get($this->recent_bg_table)->result_array(); $musiclist = $this->db->get($this->recent_music_table)->result_array(); $data = $this->db->get_where($this->recent_imgtext_table, ['imgtextid' => $imgtextid])->row_array(); if (IS_POST) { $imgtextid = $this->input->post('imgtextid'); $data = [ 'title' => $this->input->post('title'), 'cover' => $this->input->post('o_cover'), 'username' => $this->input->post('username'), 'bgid' => $this->input->post('bgid'), 'musicid' => $this->input->post('musicid'), 'ishot' => $this->input->post('ishot'), 'content' => htmlspecialchars($this->input->post('content')), 'title_color' => $this->input->post('title_color'), ]; $file = 'cover'; $save_path = 'upload/imgtext/cover'; if ($_FILES[$file]['error'] == 0) { $res = $this->uploadimg($file, $save_path); if ($res['errcode'] == 0) { $data['cover'] = $res['url']; } } $this->db->update($this->recent_imgtext_table, $data, ['imgtextid' => $imgtextid]); redirect('/recentimgtext/index'); } $data['content'] = str_replace("'",""", $data['content']); $this->load->view('recentimgtext/addimgtext', ['data' => $data, 'template' => $template, 'musiclist' => $musiclist, 'title' => '修改图文']); }
修改配置：config.php
$config['sess_save_path'] = BASEPATH.'../'.'session_file';
自动加载：autoload.php
$autoload['libraries'] = array('session'); $autoload['helper'] = array('common', 'url', 'cookie');
