Question

具有控制器功能：

public function pageedit($id)
{
    $page = Pages::where('pgeID','=',121)->get();
    return view('admin.pageedit')->with('page',$page);
}

一个简单的观点：

@extends('admin')

@section('content')
    @include('/partials/adminpageheader')
    Edit Page {{ $page }}
@endsection

当我运行它时，我得到如下输出：

Intranet Web Control Panel (Pages)
Admin Home - Admin Home Page
Edit Page
[{"pgeID":"121","pgeActive":"0","pgeContent":"1","pgeMainLevel":"6","pgeLevel":"1","pgeParent":"6","pgeOrder":"3","pgeTitle":"Employee Assistance Program","pgeHeader":"Null","pgeBody":Employee Assistance Program that all employees can access 24\/7. The website, www.assist.com has an amazing amount of information available. If you are looking for training, articles, resources and more, check them out. The use","pgeNav":null,"pgeContents":"Null","pgeCallOut":"Null","pgeEditor":"Null","pgeTitleDRAFT":"Null","pgeTemplateDRAFT":null,"pgeNavDRAFT":null,"pgeContentsDRAFT":"Null","pgeCallOutDRAFT":"Null"}]

所以我知道它正在正确地提取数据。但是当我尝试显示JUST页面标题（pgeTitle）时，如果我尝试{{$ page-＆gt; pgeTitle}}我会得到一个未定义的属性错误，如果我尝试{{$ page [＆＃39; pgeTitle＆＃39;]}}

我知道它必须是我忘记的简单事物，但如果我能弄明白它是什么，我将会感到危险。想法？

Answer 1

$page是一个数组，据我所知，索引是数字的，所以你应该这样做：

{{$page[0]->pgeTitle}}

Answer 2

而不是使用->get()使用->first()。这将返回单个实例而不是集合，这是必须使用数组访问器之间的区别。

$page = Pages::where('pgeID','=',121)->first();
                                         ^
                                    first==single
                                get==array collection

Answer 3

与Taxicala相同的答案，但我建议您使用 - ＆gt; first（）方法而不是get，因为您只需要查找1行。

$page = Pages::where('pgeID','=',121)->first();

使用Laravel 5从数据库检索字段时出错
