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;
}
}

protected $hidden = [];
/**

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.
