Kohana模板$ content变量不显示任何内容 [英] Kohana template $content variable shows nothing

问题描述

我有一个Kohana控制器，可扩展Kohana模板类. Kohana模板类具有

I have a Kohana controller that extends Kohana template class. The Kohana template class has

const CONTENT_KEY = 'content';

在此控制器中，我声明了要使用的模板视图:

In this controller I have declared the template view to be used:

public $template = 'homepage_template';

在此控制器中，我还有一些方法和一些关联的视图.

Also in this controller I have some methods, and some associated views.

具有所有这些，当我在 homepage_template 视图中echo $content时，什么也没显示(视图中没有内容属于此控制器的动作). (我在动作中具有auto_render true).可能是什么原因造成的?

Having all these, when I echo $content in the homepage_template view, nothing shows (no content from the views that belong to the actions from this controller). (I have auto_render true in the actions). What can be the cause for that?

推荐答案

这就是我使用模板控制器的方式，希望对您有所帮助:

Thats how I use Template Controller, hope it will help:

<?php defined('SYSPATH') or die('No direct script access.');

class Controller_Template_Default extends Controller_Template
{
    public $template = 'templates/default';

    protected $auth;

    protected $user;

    public function before()
    {
        parent::before();

        Session::instance();

        $this->auth = Auth::instance();     

        if (($this->user = $this->auth->get_user()) === FALSE)
        {
            $this->user = ORM::factory('user');
        }

        if($this->auto_render)
        {
            $this->template->title            = '';
            $this->template->meta_keywords    = '';
            $this->template->meta_description = '';
            $this->template->meta_copywrite   = '';
            $this->template->header           = '';
            $this->template->content          = '';
            $this->template->footer           = '';
            $this->template->styles           = array();
            $this->template->scripts          = array();
            $this->template->bind_global('user', $this->user);
        }
    }

    public function after()
    {
        if($this->auto_render)
        {
                $styles                  = array('css/default.css' => 'screen', 'css/reset.css' => 'screen');
                $scripts                 = array('js/infieldlabel.js', 'js/menu.js', 'js/jquery.js');

                $this->template->styles  = array_reverse(array_merge($this->template->styles, $styles));
                $this->template->scripts = array_reverse(array_merge($this->template->scripts, $scripts));
            }

        parent::after();
    }
} // End Controller_Template_Default

P.S.您不应该对内容使用常量. 从Controller_TEemplate_Default扩展您的控制器，并将其绑定为$ this-> template-> content = View :: factory('view的路径');

P.S. you shouldn't use constant for content. Extend your controller from Controller_TEemplate_Default and bind it like $this->template->content = View::factory('path to the view');
