Php 将特定于控制器的数组传递给视图

要求

我正在用Laravel创建大量表单。因此，为了简单起见，我正在尝试实现一个类似于下面的方法，希望这能帮助我减少时间

定义私有变量。这些变量对于控制器中的所有函数都是通用的

将默认预定义数组传递给该控制器中的所有视图

这就是我试图实现的目标

  //defining default variables for the page. Just changing this variable will enough for this controller
private $titleForUpdations = 'University';
//Definig a default variable for the folder name. Just renaming this variable will affect all the  views
//making route with same folder name.  changing name at this place enough for this controller
private $folderName = 'universities';


public function commonArray(){
    //this array is common for all the function
    $array = [
        'mainTitle' => $this->titleForUpdations.' Management' ,
        'secondTitle' => 'Add New '.$this->titleForUpdations ,
        'add' => 'Add New '.$this->titleForUpdations ,
        'back' => 'Back to '.$this->titleForUpdations.' list',
        'detail' => $this->titleForUpdations.' Details',
        'pluralName' => $this->titleForUpdations.'ies' ];

    return $array;
}

然后我将此

$array

传递给如下视图

 public function index(University $model)
{
    //fetching all data from model and paginating it when passing to view
    return view('dboperations.'.$this->folderName.'.index', ['items' => $model->paginate(15) , $this-> commonArray()]);
}

然后我尝试访问视图中的变量，如下所示

@extends('layouts.app', ['title' => __($mainTitle)])

@section('content')
@include('users.partials.header', ['title' => __($secondTitle)])

但这会连续返回错误未定义变量

如果我

dd（$this->commonArray）

在一个函数中，它会输出我想要的，如下所示

array:6 [▼
  "mainTitle" => "University Management"
  "secondTitle" => "Add New University"
  "add" => "Add New University"
  "back" => "Back to University list"
  "detail" => "University Details"
  "pluralName" => "Universityies"
]

有人能告诉我我有什么遗漏吗？

谢谢

您没有为您的commonArray添加键名

return view('dboperations.'.$this->folderName.'.index', ['items' => $model->paginate(15) , 'commonArray' => $this-> commonArray()]);
