Laravel:从基本控制器传递数据到default.blade.php

Question

我有一个基本控制器,有一个方法可以将Twitter提要返回给我的视图.

我想在视图中将其从页面视图移动到默认刀片,以减少冗余,因为它将出现在网站范围内.如何将数据从基本控制器传递到刀片？

我可以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()
    ));
}

并在视图中,输出如下:

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

我想在default.blade.php和我的Base_Contoller中做所有这些:

<?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;
    }
}

这怎么可能？

给我一个

未定义的变量:推文

错误

Answer 1

第1步 - 只为您的推文制作视图,让我们称之为widgets/tweets.blade.php接受您的$tweets数据.如果您想要更高的性能,这使得将来很容易缓存推文视图.我们还想要一个能够为您生成推文数据的模型.

第2步 - 将推文数据传递到您的推文视图中,让我们使用View Composer进行此操作,以便逻辑与视图保持一致(但在外部).

第3步 - 创建默认布局,让我们调用它layout/default.blade.php.这将接受$content和$tweets.我们将推文视图与另一个View Composer嵌套.您可以嵌套$content在控制器操作中.

第4步 - 设置$layout你的Base_Controller.

第5步 - 获利!

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括在内 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');
    }

}

Answer 2

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

在你看来使用(刀片语法)

{{$key}}

或(PHP语法)

echo $key;
