Laravel: Passing data to default.blade.php from base controller

laravellaravel-3

提问by Fraser

I have a base controller with a method to return a twitter feed to my view.

我有一个基本控制器,有一个方法可以将 Twitter 提要返回到我的视图。

I want to move this in the view from the page view to the default blade to reduce redundancy as it will be appearing site wide. How do I pass data from the base controller to blade?

我想在视图中将它从页面视图移动到默认刀片以减少冗余,因为它会出现在站点范围内。如何将数据从基本控制器传递到刀片?

I can send it to my view from the page controller like so:

我可以将它从页面控制器发送到我的视图,如下所示:

public function get_index()
{
    ..................
    $this->layout->nest('content', 'home.index', array(
        'tweets' => $this->get_tweet()
    ));
}

and in the view, output it like this:

在视图中,输出如下:

if ($tweets)
{
    foreach ($tweets as $tweet)
    {
        ..............

I want to do all this from within default.blade.php and my Base_Contoller:

我想从 default.blade.php 和我的 Base_Contoller 中完成所有这些:

<?php
class Base_Controller extends Controller {
    /**
     * Catch-all method for requests that can't be matched.
     *
     * @param  string    $method
     * @param  array     $parameters
     * @return Response
     */
    public function __call($method, $parameters)
    {
        return Response::error('404');
    }

    public function get_tweet()
    {
        ...........
        return $tweets;
    }
}

How is this possible?

这怎么可能?

Step 1 - Make a view just for your tweets, let's call it widgets/tweets.blade.php, that will accept your $tweetsdata. This makes it very easy to cache the tweets view in the future if you want a little more performance. We also want a model that will generate the tweet data for you.

第 1 步 - 为您的推文创建一个视图,我们称之为widgets/tweets.blade.php,它将接受您的$tweets数据。如果您想要更高的性能,这使得将来缓存推文视图变得非常容易。我们还需要一个模型来为您生成推文数据。

Step 2 - Pass the tweet data into your tweets view, let's use a View Composerfor this so the logic is kept with (but outside) the view.

第 2 步 - 将推文数据传递到您的推文视图中,让我们为此使用View Composer,以便将逻辑保留在(但在视图之外)视图。

Step 3 - Create your default layout, let's call this layout/default.blade.php. This will accept $contentand $tweets. We'll nest the tweets view with another View Composer. You can nest the $contentin your controller actions.

第 3 步 - 创建您的默认布局,我们称之为layout/default.blade.php. 这将接受$content$tweets。我们将使用另一个View Composer嵌套推文视图。您可以将 嵌套$content在您的控制器操作中。

Step 4 - Set the $layouton your Base_Controller.

第 4 步 -$layout在您的Base_Controller.

Step 5 - Profit!

第 5 步 - 利润!

Note - If these are your first view composers then you'll need to include them in application/start.php

注意 - 如果这些是您的第一个视图作曲家,那么您需要将它们包含在 application/start.php



// application/models/tweets.php
class Tweets {
    public static function get($count = 5)
    {
        // get your tweets and return them
    }
}

// application/views/widgets/tweets.blade.php
@foreach ($tweets)
    {{-- do something with your tweets --}}
@endforeach

// application/views/layouts/default.blade.php
<section class="main">{{ isset($content) ? $content : '' }}</section>
<aside class="widget widget-tweets">{{ $tweets }}</aside>

// application/composers.php
View::composer('widgets.tweets', function($view)
{
    $view->tweets = Tweets::get();
});
View::composer('layouts.default', function($view)
{
    $view->nest('tweets', 'widgets.tweets');
});

// application/start.php (at the bottom)
include path('app').'composers.php';

// application/controllers/base.php
class Base_Controller extends Controller {
    public $layout = 'layouts.default';
}

// application/controllers/home.php
class Home_Controller extends Base_Controller {

    public $restful = true;

    public function get_index()
    {
        $this->layout->nest('content', 'home.welcome');
    }

}

View::share('key', 'value');

in you view use (Blade syntax)

在您的视图中使用(刀片语法)

{{$key}}

or (PHP syntax)

或(PHP 语法)

echo $key;
