Question

我想创建一个控制器文件，如果我动态创建一个菜单并且还想创建连接到这个主控制器的视图页面，它会自动创建一个函数..怎么做？

当前代码：

public function our_history() 
      { 
          $data['category']= $this->menu_model->getCategory('$lang'); 
          $data['subcategory']= $this->menu_model->getSubCategory('$lang'); 
          $this->load->view('vwMain',$data);//Left Menu } 
      }

Answer 1

按照以下步骤希望有意义。 - 管理部分 -

/ * content.php - 控制器从这里开始* /

class Content extends VCI_Controller {

# Class constructor
function __construct()
{
    parent::__construct();
    $this->load->model('content_model');
}

/*
Add page logic
*/
function edit_page($id = null)
{

    $this->_vci_layout('your_layoutname');
    $this->load->library('form_validation');
    $view_data = array();

    //Set the view caption
    $view_data['caption'] = "Edit Content";

    //Set the validation rules for server side validation
    // rule name editcontent should be defined

    if($this->form_validation->run('editcontent')) {

        //Everything is ok lets update the page data
        if($this->content_model->update(trim($id))) {
            $this->session->set_flashdata('success', "<li>Page has been edited successfully.</li>");
            $this->output->set_header('location:' . base_url() . 'content/manage_content');
        } else {
            $this->session->set_flashdata('error', "<li>Unknown Error: Unable to edit page.</li>");
            $this->output->set_header('location:' . base_url() . 'content/manage_content');
        }

    } else {

        $page = $this->content_model->get_content_page(trim($id)); 
        $view_data["id"] = $page->id;
        $view_data["page_title"] = $page->page_title;
        $view_data["page_menu_slug"] = $page->page_menu_slug;
        $view_data["page_name"] = $page->page_name;
        $view_data["page_content"] = $page->page_content;
        $view_data["status"] = $page->status;
        $this->_vci_view('content_editpage', $view_data);
    }
}

/*
Edit page logic
*/
function add_page()
{

    $this->_vci_layout('your_layoutname');
    $this->load->library('form_validation');

    $view_data = array();

    $view_data['caption'] = "Edit Content";

    if($this->form_validation->run('editcontent')) { 
        // after passing validation rule data to be saved
        // editcontent rule must be defined in formvalidations file

        //Everything is ok lets update the page data
        if($this->content_model->add()) {
            $this->session->set_flashdata('success', "<li>Page has been edited successfully.</li>");
            $this->output->set_header('location:' . base_url() . 'content/manage_content');
        } else {
            $this->session->set_flashdata('error', "<li>Unknown Error: Unable to edit page.</li>");
            $this->output->set_header('location:' . base_url() . 'content/manage_content');
        }

    } else {

        $page = $this->content_model->get_content_page(trim($id)); 
        $view_data["id"] = $page->id;
        $view_data["page_title"] = $page->page_title;
        $view_data["page_menu_slug"] = $page->page_menu_slug;
        $view_data["page_name"] = $page->page_name;
        $view_data["page_content"] = $page->page_content;
        $view_data["status"] = $page->status;
        $this->_vci_view('content_editpage', $view_data);
    }
}

} / ** * content.php - 控制器在这里结束 * /

/ * Content_model从这里开始 * /

class Content_model extends CI_Model {

// update logic goes here
function update($id = null) {
    if(is_null($id)) {
        return false;
    }

    $data = array(
        'page_title' => htmlspecialchars($this->input->post('page_title',true)),
        'page_name' => htmlspecialchars($this->input->post('page_name',true)),
        'page_content' => $this->input->post('page_content',true),
        'page_menu_slug' => htmlspecialchars($this->input->post('page_menu_slug',true)),
        'status' => htmlspecialchars($this->input->post('status',true))
    );

    $this->db->where('id', $id);
    $this->db->update('content', $data);
    return true;

}

// Add logic goes here
function add() {
    $data = array(
        'page_title' => htmlspecialchars($this->input->post('page_title',true)),
        'page_name' => htmlspecialchars($this->input->post('page_name',true)),
        'page_content' => $this->input->post('page_content',true),
        'page_menu_slug' => htmlspecialchars($this->input->post('page_menu_slug',true)),
        'status' => htmlspecialchars($this->input->post('status',true))
    );

    $this->db->where('id', $id);
    $this->db->insert('content', $data);
    return true ;
}

} / * Content_model在此处结束#Admin部分更改在此处结束 * / - 还将视图文件添加到管理部分content_editpage.php

现在转到前面部分的routes.php文件 - 最后添加以下行 -

$route['(:any)'] = 'page/view_usingslug/$1';

这适用于所有urls like --- http://yourdomainname/your_slug_name

//在前面部分再次创建一个控制器page.php -

class page extends VCI_Controller {

    function __construct()
    {
        parent::__construct();

    }

    function view_usingslug($slug='')
    {
        // retrieve the data by slug from content table using any model class and assign result to $view_dat
        $this->_vci_view('page',$view_data);
        //page.php will be your view file
    }

}

Answer 2

假设您的网址为

www.example.com/controllername/methodname/menutitle1

或

www.example.com/controllername/methodname/menutitle2

这就是你处理这些页面的方式。

public function method()
{
   $menutitle = $this->uri->segment(3);
   $query = $this->db->get_where('TableName',array('Menutitle'=>$menutitle))
   $data['content'] = $query->row()->page_content;
   $this->load->view('common_page',$data);

}
