学习 Laravel 模板 share 用法。

当前使用Laravel版本为5.2.43

涉及一个知识点 View::share(), 官方文档(此链接是Laravel5.0版本,适用于5.2)。

直接上代码:

// 文件在app\Http\Controllers\Controller.php
namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesResources;
use Illuminate\Support\Facades\View;

class Controller extends BaseController
{
    use AuthorizesRequests, AuthorizesResources, DispatchesJobs, ValidatesRequests;

    public $module; // 模块
    public function __construct()
    {
        View::share('active', [$this->module=> 'active']);
    }
}
// 文件在app\Http\Controllers\ArticleController.php
namespace App\Http\Controllers;

use App\Http\Requests;
use Illuminate\Http\Request;
use Illuminate\Support\Str;
use Auth, Gate;

use App\Article;

class ArticleController extends Controller
{
    public $module = 'article'; // 标识当前模块为'article'
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct() {
        parent::__construct();
    }
}

前台模板:

<ul class="nav navbar-nav">
  <li class="{{ isset($active['article']) ? $active['article'] : '' }}"><a href="{{ url('article') }}">文章</a></li>
 </ul>
