“htmlentities（）期望参数1是字符串，数组给定”在PHP中

Question

我的问题似乎与Laravel助手。一切工作正常，直到我一些文件更改到其他文件夹，当然我改变了路线和路线上和控制器，但现在我得到这个消息：

ErrorException in HtmlBuilder.php line 65: htmlentities() expects parameter 1 to be string, array given (View: /Library/WebServer/Documents/gamstec/resources/views/posts/create.blade.php)

这是我创建的文件：

<div class="content"> 
    <div class="container-fluid"> 
     <div class="row well bs-component"> 
      <div class="col-md-8 col-md-offset"> 
      <div class="input-group"> 

       <h3 class="text-center">Crear Nueva Publicación</h3> 
       <hr> 

       {!! Form::open(array('route' => 'posts.store', 'data-parsley-validate' => '')) !!} 

        {{ Form::label('title', ' Título:', array('class' => 'fa fa-pencil')) }} 

        {{ Form::text('title', null, array('class' => 'form-control', 'required' => '', 'maxlength' => '255')) }} 

        {{ Form::label('body', ' Contenido:', array('class' => 'fa fa-pencil-square-o')) }} 

        {{ Form::textarea('body', null, array('class' => 'form-control', 'required' => '')) }} 

        {{ Form::submit('Publicar', array('class' => 'btn btn-info')) }} 


       </div> 
      </div> <!-- col-md-8 end --> 


      <div class="col-md-4"> 
      <div class="input-group"> 
       <h3 class="text-center">Categoría e imágen</h3> 
       <hr> 


        <br> <hr> 

        {{ Form::label('badge', ' Etiqueta:', array('class' => 'fa fa-tags')) }} 

        {{ Form::text('badge', array('class' => 'form-control', 'maxlength' => '20')) }} 
        <br> <hr> 

        {{ Form::label('postimg', ' Seleccionar Imagen', array('class' => 'fa fa-picture-o')) }} 
        <br> <br> 
        {{ Form::file('postimg', array('require' => '', 'maxlength' => '255')) }} 

       {!! Form::close() !!} 

      </div> <!-- item-group end --> 
      </div> <!-- col-md-4 end --> 


     </div> <!-- end of row --> 
    </div> <!-- end of container --> 
</div> <!-- end of content --> 

这是我的控制文件：

<?php 


public function index() 
{ 
    return view('admin'); 
} 

/** 
* Show the form for creating a new resource. 
* 
* @return \Illuminate\Http\Response 
*/ 
public function create() 
{ 
    return view('posts.create'); 
} 

/** 
* Store a newly created resource in storage. 
* 
* @param \Illuminate\Http\Request $request 
* @return \Illuminate\Http\Response 
*/ 
public function store(Request $request) 
{ 
    // validate the data 
    $this->validate($request, array(
     'title' => 'required|max:255', 
     'body' => 'required', 
     )); 

    // store in database 
    $post = new Post; 

    $post->title = $request->title; 
    $post->body = $request->body; 
    $post->badge = $request->badge; 
    $post->postimg = $request->postimg; 

    $post->save(); 

    Session::flash('success', 'La publicación se ha creado correctamente'); 

    // redirect to another page 
    return redirect()->route('show', $post->id); 
} 

/** 
* Display the specified resource. 
* 
* @param int $id 
* @return \Illuminate\Http\Response 
*/ 
public function show($id) 
{ 
    $post = Post::find($id); 
    return view('show')->withPost($post); 
} 

/** 
* Show the form for editing the specified resource. 
* 
* @param int $id 
* @return \Illuminate\Http\Response 
*/ 
public function edit($id) 
{ 
    // 
} 

/** 
* Update the specified resource in storage. 
* 
* @param \Illuminate\Http\Request $request 
* @param int $id 
* @return \Illuminate\Http\Response 
*/ 
public function update(Request $request, $id) 
{ 
    // 
} 

/** 
* Remove the specified resource from storage. 
* 
* @param int $id 
* @return \Illuminate\Http\Response 
*/ 
public function destroy($id) 
{ 
    // 
} 

我会是你的帮助表示感谢。

Answer 1

这就是线生成错误：

{{ Form::text('badge', array('class' => 'form-control', 'maxlength' => '20')) }} 

可以传递一个额外值选项作为第二个参数不能是一个数组

要添加其他属性，传递第三个参数的方法。这第三个参数必须是一个数组。

改成这样：

{{ Form::text('badge', '', array('class' => 'form-control', 'maxlength' => '20')) }} 

Answer 2

这是这一行代码：

{{ Form::text('badge', array('class' => 'form-control', 'maxlength' => '20')) }} 

它需要null作为第二个值：

{{ Form::text('badge', null, array('class' => 'form-control', 'maxlength' => '20')) }}
