在CodeIgniter中包含视图的最佳方法。

I'm starting a large codeigniter project and would like to try to create some reusable 'mini' views for snippets of content like loops of data which may be displayed on different pages/controllers.

我正在启动一个大型的codeigniter项目，我想尝试创建一些可重用的“迷你”视图，用于内容的片段，比如可以在不同的页面/控制器上显示的数据循环。

Is it better to call the views from within the main controller's view? If so, how? Or should I call the 'mini view' from the controller and thus pass the view's code to the main view?

从主控制器的视图中调用视图是否更好?如果是这样,如何?或者我应该从控制器调用“mini view”，从而将视图的代码传递给主视图?

Views within other views are called Nested views. There are two ways of including nested views in CodeIgniter:

其他视图中的视图称为嵌套视图。在CodeIgniter中包含嵌套视图有两种方法:

1. Load a nested view inside the controller

Load the view in advance and pass to the other view. First put this in the controller:

提前加载视图并传递到另一个视图。首先把这个放在控制器中:

<?php
// the "TRUE" argument tells it to return the content, rather than display it immediately
$data['menu'] = $this->load->view('menu', NULL, TRUE);
$this->load->view ('home', $data);
?>

Then put <?=$menu?> in your view at the point you want the menu to appear.

然后把< ? = $菜单吗?在您的视图中，您希望菜单出现的位置出现>。

2. Load a view "from within" a view

First put this in the controller:

首先把这个放在控制器中:

<?php
  $this->load->view('home');
?>

Then put this in the /application/views/home.php view:

然后把这个放到/application/view /home。php视图:

<?php $this->view('menu'); ?>

<p>Other home content...</p>

About best method, I prefer the 1st method over 2nd one, because by using 1st method I don't have to mix up code, it is not like include php. Although indirectly both are same, the 1st method is clearer & cleaner than 2nd one!

关于最佳方法，我更喜欢第一种方法而不是第二种方法，因为使用第一种方法我不需要混淆代码，它不像包含php。虽然间接地两者都是一样的，但是第一种方法比第二种更清晰、更干净!

Honestly I prefer to do this by having template views then loading that with the necessary data from the controller, it means a lot less repeated code and follows the DRY concept better than loading views from views. Especially for things like headers, footers and menus.

老实说，我更喜欢使用模板视图来实现这一点，然后用来自控制器的必要数据来加载这些视图，这意味着重复代码要少得多，并且比从视图加载视图更好地遵循DRY概念。特别是对于页眉、页脚和菜单。

So my template view would look something like this:

我的模板视图是这样的

template.php

template.php

$this->load->view('header',$title);
$this->load->view('sidebar',$sidebar_content);
$this->load->view('main_content',$main_content);
$this->load->view('footer');

Then in my controller I pass the data required to the template like this:

然后，在我的控制器中，我将所需的数据传递给模板，如下所示:

$data['title'] = 'Home Page';
$data['sidebar_content']='pages/standard_sidebar';
$data['main_content'] ='pages/my_home_page'; 
$this->load->view('template',$data);

There are a number of benefits to doing it this way. First is I can have multiple templates, for example I have, in my case, two main ones, one for full page views without a sidebar and one for pages with a sidebar, I also call an if statement to decide which header to include, the regular one or the one with the admin menu in it.

这样做有很多好处。首先是我可以有多个模板,比如我,在我的例子中,两个主要的,一个完整的页面浏览量没有侧边栏和页边栏,我也叫一个if语句来决定哪个头包括定期与管理一个或一个菜单。

Yes I could include the header, sidebar and footer in every main view page, but that ends up in a ton of duplicate code. And what happens if for example I want all my pages to have something new, some other small snippet? Using templates I add the snippet to the appropriate template and it's done. Going the other route I find every page and add the snippet view there, it's the equivalent to having CSS in the page in my opinion, wasteful and not ultimately maintainable.

是的，我可以在每个主视图页面中包含页眉、侧边栏和页脚，但那将导致大量重复的代码。如果我想让我所有的页面都有一些新的东西，一些其他的小片段，会发生什么?使用模板，我将代码片段添加到适当的模板中，这样就完成了。按照另一种方式，我找到每一个页面并在其中添加snippet视图，在我看来，这相当于在页面中添加CSS，既浪费又不能维护。

METHOD 1

方法1

I use this method into my view to insert the include view where I want

我在视图中使用这个方法来插入我想要的包含视图。

$this->load->view('include/include_view');

METHOD 2

方法2

or in the controller you can load kore than a view like this:

或者在控制器中，你可以加载kore，而不是像这样的视图:

$this->load->view('header_view');
$this->load->view('list_view');
$this->load->view('footer_view');

Isn't a better method, depends if you have to pass some data (int his case use the method2) or if you want to include a view in a specific part of your main view (in this case is better to use the method 1)

这不是一个更好的方法，这取决于您是否需要传递一些数据(在他的案例中使用method2)，或者如果您想在主视图的特定部分中包含一个视图(在本例中，最好使用方法1)

METHOD 3

方法3

Passing data to your include view by your main view

通过主视图将数据传递给包含视图

into your controller:

控制器:

$data['title'] = "Title";
$this->load->view('main_view',$data);

in your view

在你的观点

$data2['title'] = $title;
$this->load->view('include/include_view',$data2);

If you want to pass entire data to your include view you can do in this mode: in your controller:

如果您想将整个数据传递给包含视图，可以使用以下模式:在控制器中:

$data['nestedView']['title'] = 'title';

in your view

在你的观点

$this->load->view('includes/included_view', $nestedView);

#4

This a simple way of including views within views.there is no need to load views in advance.just pass view path to other view.

这是包含视图内视图的简单方法。不需要预先加载视图。通过查看路径到其他视图。

In your controller use this:

在您的控制器中使用:

$data['middle'] = 'includeFolder/include_template_view';  //the view you want to include
$this->load->view('main_template_view',$data);  //load your main view

and in main_template_view you can include other views :

在main_template_view中，可以包含其他视图:

$this->load->view($middle);

In my opinion for solve in more efficient way this problem I have done so:

在我看来，为了更有效地解决这个问题，我这样做了:

You create a new helper (in application/helpers) with name (es. common_helpers.php, the underscore is important). In this file, you put all the functions for example build pieces of html in common.

您将创建一个具有名称的新助手(在应用程序/助手中)。common_helpers。php，下划线很重要)。在这个文件中，您将所有的函数(例如构建html片段)放在一起。

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

    function getHead(){
    require_once(APPPATH."views/common/head.php");
    }   

    function getScripts(){
    require_once(APPPATH."views/common/scripts.php");
    }

    function getFooter(){
    require_once(APPPATH."views/common/footer.php");
    }

In your controller you call only one view in respect of MVC and call the functions from your custom helper.

在您的控制器中，您只调用一个MVC视图，并从自定义助手调用函数。

class Hello extends CI_Controller {

   public function index(){
       $this->load->helper('common');
       $this->load->view('index');   
   }

}
