Laravel htmlspecialchars() 期望参数 1 为字符串，object 在我的项目中给出？

Question

所以我正在尝试编写一个简单的网站表单。但是它有这个 htmlspecialchars 错误。

我试过制作{{ $message }}，但没成功。有同样的错误。

这是我的控制器：

<?php
namespace App\Http\Controllers;
use Mail;
use Illuminate\Http\Request;
class ContactMessageController extends Controller
{
public function create()
    {
        return view('form');
    }

public function store(Request $request)
{
    $this->validate($request, [
        'name' => 'required',
        'email' => 'required|email',
        'address' => 'required',
    ]);

    Mail::send('emails.contact-message', [
        'message' => $request->message
    ], function($mail) use($request) {
        $mail->from($request->email, $request->name);

        $mail->to('john@example.com')->subject('Contact message');
    });

        return redirect()->back()->with('flash_message', 'thanks');
    }
}

这是我的 blade

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>Customer Details</title>

        @if (Session::has('flash_message'))
            <div class="alert alert-success">{{ Session::get('flash_message') }}</div>
        @endif
    <form method="post" action="{{ route('contact.store') }}">
    {{ csrf_field() }}
        <div class="form-group">
            <label>Full Name : </label>
            <input type="text" class="form-control" name="name">
            @if ($errors->has('name'))
                <small class="form-text invalid-feedback">{{ $errors->first('name') }}</small>
            @endif
        </div>

        <div class="form-group">
            <label>Email : </label>
            <input type="text" class="form-control" name="email">
            @if ($errors->has('email'))
                <small class="form-text invalid-feedback">{{ $errors->first('email') }}</small>
            @endif
        </div>

        <div class="form-group">
            <label>Address : </label>
            <textarea name="address" class ="form-control"></textarea>
            @if ($errors->has('address'))
                <small class="form-text invalid-feedback">{{ $errors->first('address') }}</small>
            @endif
        </div>

        <div class="form-group">
            <label>Message : </label>
            <textarea name="message" class ="form-control"></textarea>
            @if ($errors->has('message'))
                <small class="form-text invalid-feedback">{{ $errors->first('message') }}</small>
            @endif
        </div>

        <button class="btn btn-primary">Submit</button>


    </form>
</div>

</body>
</html>

这是我的 contact-message.blade.php

{{ $message }}

我也试过了 {{dd($message)}}

但是没用。

请帮忙。

Answer 1

你应该试试这个：

public function store(Request $request)
{
    $this->validate($request, [
        'name' => 'required',
        'email' => 'required|email',
        'address' => 'required',
    ]);

    $fromName = $request->name;
      $subject = "MailSent";
      $data = array(
        'message' => $request->message
        );

      $fromEmail = $request->email;

      $toName = 'test';
      $toEmail = 'john@example.com';


      Mail::send('emails.contact-message', $data, function($message) use ($toEmail, $toName, $fromEmail, $fromName, $subject){ 

        $message->from($fromEmail, $fromName);
        $message->to($toEmail, $toName);
        $message->subject($subject);
      });

        return redirect()->back()->with('flash_message', 'thanks');
    }
}

Answer 2

只需将控制器中的数组键从 message 更改为 messages，如下所示：

$data = array(
        'messages' => $request->message
        );

并且在 blade 中打印为 {{$messages}}

A $message variable is always passed to e-mail views, and allows the inline embedding of attachments. So, it is best to avoid passing a message variable in your view payload.
