Laravel，视图中未定义的变量

Question

我试图解决我的问题，但我被困在这里无法解决为什么变量在 home.blade.php
中未定义的原因我的 HomeController.php 我有 $items 变量导致问题

<?php
 use app\Item;
 namespace App\Http\Controllers;

class HomeController extends BaseController
{
    public function __construct(Item $items)
    {
        $this->items = $items;
    }

    public function getIndex()
    {
        $items = Auth::user()->items;

        return View::make('home', array(
        'items' => $items    
        ));
    }



    public function postIndex()
    {
        $id = Input::get('id');
        $useId = Auth::user()->id;

        $item = Item::findOrFail($id);

        if($item->owner_id == $userId)
        $item -> mark();

        return Redirect::route('home');
    }
}
?>

这是项目 class，我用 eloquent

对其进行了扩展

<?php
class Item extends Eloquent
{
    public function mark()
    {
        $this->done = $this->done?false:true;
        $this->save();
    }
}

虽然我有 items 的另一个功能，但我试图将其用作变量，因为这是 user.php[= 的文件35=] 函数定义在末尾

<?php namespace App; use Illuminate\Auth\Authenticatable; use Illuminate\Database\Eloquent\Model; use Illuminate\Auth\Passwords\CanResetPassword; use Illuminate\Foundation\Auth\Access\Authorizable; use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract; use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract; use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract; class User extends Model implements AuthenticatableContract, AuthorizableContract, CanResetPasswordContract { use Authenticatable, Authorizable, CanResetPassword; /** * The database table used by the model. * * @var string */ protected $table = 'users'; /** * The attributes that are mass assignable. * * @var array */ protected $fillable = ['name', 'email', 'password']; /** * The attributes excluded from the model's JSON form. * * @var array */ protected $hidden = ['password', 'remember_token']; public function items() { return $this->hasMany('Item','owner_id'); } }

这是来自视图 home.blade.php 的文件，它在 foreach 循环中给出错误
错误：b5a9f5fc2ee329af8de0b5c94fd30f78 第 7 行中的 ErrorException：未定义的变量：项目（视图：C:\Users\Rehman_\Desktop\todo-application\resources\views\home.blade.php）

@extends('master') @section('content') <h1>TO DO: Items</h1> <hr> <ul> @foreach ($items as $item) @endforeach </ul> @stop

更新：Route.php 文件

<?php Route::get('/',array('as'=>'home','uses'=>'PageController@getindex'))->before('auth'); Route::post('/',array('uses','HomeController@postIndex'))->before('csrf'); Route::get('/login',array('as'=>'login','uses' => 'Auth\AuthController@getLogin'))->before('guest'); Route::post('login',array('uses' => 'Auth\AuthController@postLogin'))->before('csrf');

Answer 1

您的路线可能指向错误 controller/method 因此变量未发送到视图。

尝试：

 Route::get('/', [ 'as'=>'home','uses'=>'HomeController@getIndex'] );

Answer 2

试试这个：

return View('home', compact('items'));

而不是这个：

return View::make('home', array(
    'items' => $items    
));
