模型 - 视图 - 控制器（MVC）是软件工程中使用的架构模式。对于Microsoft ASP.NET MVC，请改用[asp.net-mvc]或[asp.net-core-mvc]标签。对于Spring MVC，请改用[spring-mvc]标签。
$this->load->view('confirm_data_v', $a_1, $a_2);
public function get_all_subjects() { return $this->db->get('subjects'); }
如何通过控制器的模型方法结果到codeigniter中的查看 我想创建简单的搜索功能。我跟随一些例子。但是我无法获得结果。 查看页面
Controller function search_keyword() { $keyword = $this->input->post('keyword'); $data['results'] = $this->mymodel->search($keyword); $this->twig->display('result_view.php', $this->data); //$this->load->view('result_view.php', $data); } 模型 function search($keyword) { $this->db->like('item_name', $keyword); $query = $this->db->get('bracelets'); return $query->result(); } 改变 $this->twig->display('result_view.php',$this->data); to $this->load->view('result_view.php',$data); 使用此功能 function search_keyword() { $keyword=$this->input->post('keyword'); $data['results']=$this->mymodel->search($keyword); $this->twig->display('result_view.php',$data); }
呼吸引用的变量并未被渲染为其在CodeIgniter Active Record查询中的值
有人可以在代码上帮助我完成我的搜索功能吗？我是新的php和IM使用Codeigniter框架进行开发。 搜索视图 <div id="admin-col"> <div> <?php echo form_open('search_admin/search_admins'); ?> <?php $data = array('name' => 'search', 'id' => 'search'); echo form_input($data); ?> <?php $data = array( 'name' => 'submit', 'id' => 'submit', 'value' => 'Search Admin' ); echo form_submit($data); ?> </div> Controllerclass Search_admin extends CI_Controller { function __construct() { parent::__construct(); $this->load->helper(array('form', 'url')); $this->load->library('form_validation'); $this->load->library('security'); $this->load->library('tank_auth'); $this->load->model('users/usermodel'); } function index() { if (!$this->tank_auth->is_logged_in()) { redirect('/auth/login'); } else { $data['user_id'] = $this->tank_auth->get_user_id(); $data['username'] = $this->tank_auth->get_username(); } } function search_admins() { $data['query']=$this->usermodel->search_admins( $this->input->post('search') ); $this->load->view('admin/users/search_result', $data); } } 模型 class UserModel extends CI_Model { function _construct() { parent::_construct(); $this->load->helper(array('form', 'url')); $this->load->library('form_validation'); $this->load->library('security'); $this->load->library('tank_auth'); $this->load->model('users/usermodel'); $this->load->database(); } function search_admins($search) { return $query = $this->db->get_where('users', array('username =' => '$search'))->result(); } } the结果查看 <div id="admin-col"> <table> <tr> <th>ID</th> <th>Username</th> <th>Email Address</th> <th>Actions</th> </tr> <?php foreach ($query as $row) { ?> <tr> <td><?php print $row->id; ?></td> <td><?php print $row->username; ?></td> <td><?php print $row->email; ?></td> <td> <?= anchor('userslist/get_Admin/' . $row->id, 'Edit');?> | <?= anchor('userslist/deleteAdmin/' . $row->id, 'Delete'); ?> </td> </tr> <?php }?> </table> </div> 你有 array('username ='=> '$search') 在您的search_admins()函数 array('username'=> $search) instead
我想在我的模型中从称为司法管辖区的表中进行查询。 现在，我希望此查询提供有效的MySQL结果资源。即，我想将结果传递到mysql_fetch_array（）。 如果我...
