laravel 实现向公共模板中传值 (view composer)

php artisan make:provider ComposerServiceProvider

public function boot() {  view()->composer(   'app', //模板名   'App/Http/ViewComposers/MovieComposer' //方法名或者类中的方法  ); }

view()->composer('app','App/Http/ViewComposers/MovieComposer@foobar'); //自己定义的方法

<?phpnamespace App/Http/ViewComposers;use Illuminate/View/View;//**记得引入这个啊（因为在composer函数参数里使用了View类）**class MovieComposer{ public $movieList = []; public function __construct() {  $this->movieList = [   'Shawshank redemption',   'Forrest Gump',  ]; } public function compose(View $view) {  $view->with('latestMovie'); }}

view()->composer('*', function (View $view) { //logic goes here});

view()->composer(['nav', 'footer'],'App/Http/ViewComposers/MovieComposer');

 view()->composer(['admin.admin'], function ($view){   $column = $this->object_array(DB::table('column')->get());   foreach($column as $k=>$v){    $chid = explode(',',$v['childid']);    foreach($chid as $value){     $column[$k]['chname'][] = $this->object_array(DB::table('column_child')->where('id',$value)->first());    }   }   $view->with('columns',$column);  });
