因此，我正在使用Framework Laravel 5.3开发Web应用程序，包括laravel-backpack和使用PHP版本5.6.30。我是从我的应用程序的场阿贾克斯试图使用字段类型选择2，但我得到的错误是说我的代码有4bb1a9dc582e785d21cadb68014f51787068f3ed.php行语法错误90.使用背包字段类型的PHP版本5.6.30得到了框架Laravel 5.3的问题从ajax中选择
然后我看向文件：
我的控制器是：
<?php
namespace App\Http\Controllers\Admin;
use Backpack\CRUD\app\Http\Controllers\CrudController;
// VALIDATION: change the requests to match your own file names if you need form validation
use App\Models\Report;
use App\Http\Requests\ReportRequest as StoreRequest;
use App\Http\Requests\ReportRequest as UpdateRequest;
class ReportCrudController extends CrudController
{
public function setUp()
{
/*
|--------------------------------------------------------------------------
| BASIC CRUD INFORMATION
|--------------------------------------------------------------------------
*/
$this->crud->setModel("App\Models\Report");
$this->crud->setRoute("admin/report");
$this->crud->setEntityNameStrings('report', 'reports');
/*
|--------------------------------------------------------------------------
| BASIC CRUD INFORMATION
|--------------------------------------------------------------------------
*/
//$this->crud->setFromDb();
$this->crud->setColumns([

我会尽力修复代码但失败。最后，我最终在这里试图从你们那里得到帮助。感谢您的关注。
你试图将PHP代码转换为JavaScript文件。这将无法正常工作。 – Ohgodwhy
尽管不是很好的做法，但它也不应该抛出错误。向我们展示发生这种情况的视图。这是编译的缓存视图，找到原始视图。你正在做'$ field ['value']？旧的（$ field ['name']）?? 0'某处。这是不正确的PHP 5.6语法 – devk
