刀片视图不打印阵列中的数据 [英] Blade view not printing data from array

问题描述

我要打印的用户信息足够简单.

I've got a simple enough array of user information I'm trying to print.

我可以将信息发送到视图中.像这样的命令:

I can send the information to the view fine. And a command like:

{{$ who-> name}}会给我这个名字.

{{ $who->name }} will give me the name.

但是，当我执行一个foreach循环以打印数组中的所有数据时，我得到了一堆数字. 1 1 1和空格.

However when I do a foreach loop to print all the data in the array I get a bunch of numbers. 1 1 1 and blank spaces.

  @foreach ($who as $val)

          {{ $val }}

     @endforeach

这是怎么回事?

此外，由于数组具有每个值的标题:即"Name":"John Doe"，有没有办法分别打印标题?

Also, as the array has the titles of each value: ie "Name": "John Doe", is there a way to print the titles separately?

这是控制器:

 public function show(UserEdit $object) {
       return view('UserEdit', compact('object'));
   }

请注意，控制器正在加载模型UserEdit，该模型具有用户的数据，并且ID是从路线生成的.我已经确认有效.

Note the controller is loading the model UserEdit, which has the user's data, and the id is generated from the route. Which I've confirmed works.

更新文件:

UserEdit.blade:

UserEdit.blade:

@extends('layout')


@section('content')
    <h1>User Profile Data {{ $object->First_Name }} {{ $object->Last_Name }}</h1>
        <br><br>

             @foreach ($object as $key=>$value)
                 {{ $key }}  {{ $value }}
             @endforeach


@stop

给出错误:尝试获取非对象的属性

Gives error: Trying to get property of non-object

UserEntryController:

UserEntryController:

namespace App\Http\Controllers;
use App\UserEdit;
use Illuminate\Http\Request;
use DB;
use App\Http\Requests;

class UserEntryController extends Controller
{
   public function index(){
       $columns = DB::getSchemaBuilder()->getColumnListing('users');
       $profile = UserEdit::all()->where('ID', '530');
       return view('UserEntry', compact('profile', 'columns'));
   }

   public function show(UserEdit $object) {
       //$columns = DB::getSchemaBuilder()->getColumnListing('users');
      // $profile = UserEdit::all()->where('ID', '530');
      // $who = UserEdit::find($ID);
       $object = $object->toArray();
       return view('UserEdit', compact('object'));
       //return $object;
   }

}

Route::get('/', function () {

Auth::routes();

Route::get('/home', 'HomeController@index');

Route::get('DB', 'DBController@index');
            //$tables = DB::select('SHOW TABLES');

UserEdit:

<?php

use Illuminate\Database\Eloquent\Model;

class UserEdit extends Model  {



    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'users';

    /**
     * Attributes that should be mass-assignable.
     *
     * @var array
     */
    protected $fillable = ['ID', <--67 values-->, 'remember_token'];

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = [];

    /**
     * The attributes that should be casted to native types.
     *
     * @var array
     */
    protected $casts = [];

    /**
     * The attributes that should be mutated to dates.
     *
     * @var array
     */
    protected $dates = [];

}

推荐答案

您正在发送的对象仅用于查看.因此，掠过那个物体给你1 1 1.

Your are sending object only to view. So lopping though that object giving you 1 1 1.

这就是为什么它对您有用 {{$ obj-> name}}

That's why this is working for you {{ $obj->name }}

将对象转换为数组

public function show(UserEdit $object) {
   $object = $object->toArray();
   return view('UserEdit', compact('object'));
}

通过该数组循环

@foreach($object as $key=>$value)
   {{ $key }} - {{ $value }}
@endforeach

从@Mugluck 快速说明，适用于在这种情况下使用模型类型提示时获得未定义的变量"的人.我用这个解决了这个问题($ who是路线，在这种情况下是ID):

Edit from @Mugluck: A quick note, for people who get "Undefined variable" when using the model type hint in this scenario. I solved it with this ($who is the route, which in this case is the ID):

   public function show($who) {
       $array = UserEdit::find($who)->toArray();
       return view('UserEdit', compact('array'));
   }

道歉的代码.但这应该给您结果.

Apologies for mangled code. But this should give you the result.
