定义控制器外部的内容 - Defining content outside the controller?

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

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

正如您所看到的，控制器方法可能会变得有点混乱。我正在寻找一个更清洁的解决方案，我不必在控制器方法中定义$heading['panelText']的值？也许创建一个库来拥有$heading内容的列表，控制器将使用该库，或者我该如何处理？

这只适用于控制器吗？如果是这样的话，我会创建一个ControllerClass并从此扩展我的所有控制器。类似这样的东西：

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);
    }
}

然后在你的控制器上，你可以做这样的事情：

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');
    }
}

辅助程序类的替代方案：

<?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);
    }
}

然后在你的控制器上，你可以做这样的事情：

<?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composer，它将自动将其附加到所有视图中。

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