Laravel 5列出htmlentities()期望参数1为字符串 [英] Laravel 5 lists htmlentities() expects parameter 1 to be string

问题描述

我有以下内容:

\ App \ Models \ Finance \ FinanceAccount :: lists('name'，'id')

\App\Models\Finance\FinanceAccount::lists('name', 'id')

在我的一种观点的顶部，但它总是给我错误:

At the top of one of my views but it keeps giving me the error:

htmlentities() expects parameter 1 to be string, array given (View: mysite\views\modals\add.blade.php)

我在做什么错了?

这是一个数组，这很有意义，我将其放入一个选择中，它现在可以正常工作:

That makes sense about it being an array, I put it into a select and it's working now:

<div class="form-group">
      {!!Form::label('Account')!!}
      {!!Form::select('account', \App\Models\Finance\FinanceAccount::getSelectOptions(), 1, ['class' => 'form-control'])!!}
  </div>

是否可以为视图设置名称空间，所以我不必一直输入完整的名称空间?

Is there a way to set the namespace for views, so I don't have to type the full namespace all the time?

推荐答案

lists给出了一个数组，您不能使用{{ }}回显该数组.您需要做的就是如果要打印其内容，则循环或implode该数组.

lists gives an array and that's not something you can echo out with {{ }}. What you need to do is to loop or implode the array if you want to print it's content.

使用foreach

@foreach ($list as $item)
    {{ $item }}<br />
@endforeach

使用 implode

{{ implode(', ', $list) }}

使用Form::select

{!! Form::select('foo', $list) !!}

如果您不想在视图中使用命名空间(永远不要使用)，请

---

If you don't want to use your namespace (which you never should) in your view, send the data from your controller to your view file.

如果您的控制器中有此

public function foo() {
    $baz = \App\Models\Finance\FinanceAccount::getSelectOptions();

    return view('bar', compact('baz'));
}

$baz变量随即在您的视图文件中可用.因此，您可以执行以下操作:

The $baz variable is then available in your view file. So you can do this:

{!! Form::select('foo', $baz) !!}
