在 Laravel 中，控制器中的每个方法都将包含$heading['panelText']

例如：

   public function pageName1()
    {
     $heading['panelText'][] = "Content Here one";
     $heading['panelText'][] = "Content Here Two";
     $heading['panelText'][] = "Content Here Three";

     return View('mockup/pagename1', compact('heading'));
    }

   public function pageName2()
    {
     $heading['panelText'][] = "Some Random one";
     $heading['panelText'][] = "Some Random Line Two";

     return View('mockup/pagename2', compact('heading'));
    }

在刀片文件中，它看起来像这样

   @foreach($heading['panelText'] as $content)
        <p>{{$content}}</p>
   @endforeach

如您所见，控制器方法可能会有些混乱。我正在寻找一种更清洁的解决方案，我不必$heading['panelText']在控制器方法中定义值？也许创建一个库来包含$heading内容列表，并且控制器将使用该库或者我该怎么做？

这仅适用于控制器吗？如果是这样，我将创建一个 ControllerClass 并从中扩展我的所有控制器。像这样的东西：

class HeadController extends Controller
{
    protected $heading = [];

    public function header1(){
        $this->heading['panelText'][] = "Content Here one";
        $this->heading['panelText'][] = "Content Here Two";
        $this->heading['panelText'][] = "Content Here Three";

        return $this;
    }

    public function header2(){
        $this->heading['panelText'][] = "Some Random one";
        $this->heading['panelText'][] = "Some Random Line Two";

        return $this;
    }

    public function setPanelText(array $panelTexts){
        foreach($panelTexts as $panelText){
           $this->heading['panelText'][] = $panelText;
        }

        return $this;
    }

    public function loadView($view){
        return View($view)->withHeading($this->heading);
    }
}

然后在您的控制器上，您可以执行以下操作：

class YourController extends HeadController{
    public function pageName1(){
        return $this->header1()->loadView('mockup/pagename1');
    }

    public function pageName2(){  
        return $this->header2()->loadView('mockup/pagename2');
    }

    public function customPage3(){
        //setting on the controller

        $panelTexts = [
            "Some Random line One for page 3",
            "Some Random Line Two for page 3",
        ];

        return $this->setPanelText($panelTexts)->loadView('mockup/pagename3');
    }
}

辅助类的替代方案：

<?php namespace Your\Namespace;

use View;

class Helper
{
    protected $heading = [];

    public function header1(){
        $this->heading['panelText'][] = "Content Here one";
        $this->heading['panelText'][] = "Content Here Two";
        $this->heading['panelText'][] = "Content Here Three";

        return $this;
    }

    public function header2(){
        $this->heading['panelText'][] = "Some Random one";
        $this->heading['panelText'][] = "Some Random Line Two";

        return $this;
    }

    public function setPanelText(array $panelTexts){
        foreach($panelTexts as $panelText){
           $this->heading['panelText'][] = $panelText;
        }

        return $this;
    }

    public function loadView($view){
        return View($view)->withHeading($this->heading);
    }
}

然后在您的控制器上，您可以执行以下操作：

<?php namespace Your\Controllers\Namespace;

use Your\Namespace\Helper;

class YourController extends Controller{

    protected $helper;

    public function __construct(Helper $helper){
        $this->helper = $helper;
    }

    public function pageName1(){
        return $this->helper->header1()->loadView('mockup/pagename1');
    }

    public function pageName2(){  
        return $this->helper->header2()->loadView('mockup/pagename2');
    }

    public function customPage3(){
        //setting on the controller

        $panelTexts = [
            "Some Random line One for page 3",
            "Some Random Line Two for page 3",
        ];

        return $this->helper->setPanelText($panelTexts)->loadView('mockup/pagename3');
    }
}

您可以创建一个作曲家，它会自动将其附加到您的所有视图中。

view()->composer('*', function($view) {
    $panelText = [
        'Content Here one',
        'Content Here Two',
        'Content Here Three'
    ];

    return $view->with('panelText', $panelText);
});

您可以在此处阅读有关视图作曲家的更多信息：https ://laravel.com/docs/5.2/views#view-composers
