Codeigniter Setting Homepage ( Default Controller )
提问by Serip88
I'm trying to implement page templating in my codeigniter application, templating is working fine for instance, i have a blog page, which i'm trying to assign as my homepage, with different view and pagination and so on. When i write www.mywebsite.com/blog, it gets opened in homepage template, or assume that i have a page www.mywebsite.com/about , it gets opened in page template too. But when i try to access my website via www.mywebsite.com, i have a 404 error page. How can i assign my blog page as the homepage ?
我正在尝试在我的 codeigniter 应用程序中实现页面模板，例如，模板工作正常，我有一个博客页面，我试图将其分配为我的主页，具有不同的视图和分页等等。当我写 www.mywebsite.com/blog 时，它会在主页模板中打开，或者假设我有一个页面 www.mywebsite.com/about，它也会在页面模板中打开。但是当我尝试通过 www.mywebsite.com 访问我的网站时，我有一个 404 错误页面。如何将我的博客页面指定为主页？
Page Controller :
页面控制器：
class Page extends Frontend_Controller {
public function __construct(){
parent::__construct();
$this->load->model('page_m');
}
public function index() {
// Fetch the page template
$this->data['page'] = $this->page_m->get_by(array('slug' => (string) $this->uri->segment(1)), TRUE);
count($this->data['page']) || show_404(current_url());
add_meta_title($this->data['page']->title);
add_meta_keyword($this->data['page']->keywords);
add_meta_description($this->data['page']->description);
// Fetch the page data
$method = '_' . $this->data['page']->template;
if (method_exists($this, $method)) {
$this->$method();
}
else {
log_message('error', 'Could not load template ' . $method .' in file ' . __FILE__ . ' at line ' . __LINE__);
}
// Load the view
$this->data['subview'] = $this->data['page']->template;
$this->load->view('_main_layout', $this->data);
}
private function _page(){ // methods }
private function _homepage(){ // methods }
}
in my Routes, i have set my default controller to page controller
在我的路线中，我已将默认控制器设置为页面控制器
$route['default_controller'] = "page";

The problem is that there's no URI segment when you visit www.mywebsite.com. You can try setting the default value as:
问题是当您访问www.mywebsite.com. 您可以尝试将默认值设置为：
$this->uri->segment(1 , 'blog')

Your code
你的代码
// Fetch the page template
$this->data['page'] = $this->page_m->get_by(array('slug' => (string) $this->uri->segment(1)), TRUE);
count($this->data['page']) || show_404(current_url());
the uri segment code
uri 段代码
$this->uri->segment(1)
is looking first url segment, when you browse your site like www.yousite.come/blog it will work find but when you do www.yoursite.com 1st uri segment is missing so it will return false , so i will show 404 page.
正在寻找第一个 url 段，当您像 www.yousite.come/blog 这样浏览您的网站时，它会找到，但是当您执行 www.yoursite.com 时，第一个 uri 段丢失，因此它将返回 false，因此我将显示 404 页面。
Solution :You can just add the second parameter to the function like
解决方案：您可以将第二个参数添加到函数中，例如
$this->uri->segment(1,'blog');
now if the first url segment is missing it will not return false,it will return the default vlaue 'blog'
现在，如果第一个 url 段丢失，它不会返回 false，它将返回默认的 vlaue 'blog'
