【中文标题】htmlentities() 期望参数 1 是字符串，给定对象

【英文标题】：htmlentities() expects parameter 1 to be string, object given

【发布时间】：2015-06-27 14:21:48

【问题描述】：

我目前正在使用 Laravel 5，但如有任何建议，我们将不胜感激。我目前正在使用 laravel 的表单生成器，并且不断收到此 html 实体错误。我什至尝试将 textarea 更改为文本字段，但无济于事。下面是我的完整堆栈跟踪。

页面控制器

<?php namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Http\Requests\ContactFormRequest;





class PagesController extends Controller 

    public function home()
    

        // Mail::send('emails.contact', array('name' => 'Justin' ), function($message)
        //  $message->to('[e-mail]', 'Justin')->subject('Test');
        // );
        return view('pages.index');
    

    public function store(ContactFormRequest $request)


    \Mail::send('emails.contact',
        array(
            'name' => $request->get('name'),
            'email' => $request->get('email'),
            'phone' => $request->get('phone'),
            'message' => $request->get('message')


        ), function($message)
    
        $message->from('[e-mail]');
        $message->to('[e-mail]', 'Admin')->subject('Chyall Pharma Contact');
    );

  return \Redirect::route('/')->with('message', 'Thanks for contacting us!');

【参考方案1】：

你添加了吗

到composer.json：

“要求”： “照亮/html”：“5.0.*@dev” ,

到 app.php 提供者数组

'照亮\Html\HtmlServiceProvider'，

到 app.php 别名数组

'Html' => '照亮\Html\HtmlFacade',

'Form' => 'Illuminate\Html\FormFacade',

然后

composer update

【讨论】：

是通过 cmd 提示符完成的，但是是的，这是我在 composer.json 中有 "illuminate/html": "~5.0" 的行，其他一切都如您所述。

【参考方案2】：

问题出在PagesController里面的Mail::send。

'message' => $request->get('message');

您正在使用变量名'message'，应该避免使用它。

注意：$message 变量总是传递给电子邮件视图，并允许 附件的内联嵌入。所以，最好避免通过 视图负载中的消息变量。

来源：http://laravel.com/docs/5.0/mail#basic-usage 在第一个注释中。

您可能需要将变量名称更改为其他名称。

'bodyMessage' => $request->get('message');

别忘了更改contact.blade.php 中的变量名

<p>
Name:  $name 
</p>

<p>
 $email 
</p>

<p>
 $phone 
</p>

<p>
 $bodyMessage  // This line.
</p>

【讨论】：

谢谢。我摆脱了那个错误，但现在它说 Route [/] 未定义。我在索引页面上有我的联系表。有没有我不知道的更好的方法？

你可以用重定向方法替换它return redirect('/')->with('message', 'Thanks for contacting us!');链接laravel.com/docs/5.0/requests#obtaining-a-request-instance

酷所以它现在重定向但没有消息...有没有办法在屏幕上获取消息？它适用于错误

很好的答案 - 让我难过

如果有任何1，请在此处查看相同的问题...***.com/questions/38008979/…

【参考方案3】：

!! Form::submit('Submit', array('class'=>'btn btn-primary')) !!

这行需要一个非数组的第二个参数，试试改成：

!! Form::submit('Submit', '', array('class'=>'btn btn-primary')) !!

【参考方案4】：

当我使用错误的表单方法时，我也遇到了这个错误。要创建文本输入，请确保使用 text 方法，而不是 input 方法。

!! Form::text('name', null, ['class' => 'form-control']) !!

代替：

!! Form::input('name', null, ['class' => 'form-control']) !!

这已纠正错误。 这适用于带有Laravel Collective 的 Laravel 5.3（即 composer require "laravelcollective/html":"^5.3.0"）

【参考方案5】：

如果你想打印一个数组，必须这样做：

<?php dd($nameOfvarArray); ?>
