Question

我是Laravel的初学者。我创建了联系表单功能。

我有此代码：

public function sendContactForm($request)
    {
        $this->validate($request, [
            'name' => 'required|string',
            'topic' => 'required|string',
            'email' => 'required|email',
            'message' => 'required|string',
            'captcha' => 'required|captcha',
            'acceptReg' => 'required|integer',
        ]);
        $adminEmail = $this->frontendRepository->getSystemAdminEmail();

        $title = $request->input('topic');
        $txt = nl2br($request->input('message'));
        $userName = $request->input('name');
        $email = $request->input('email');
        $ip = $request->getClientIp();
        $dateTime = date('Y-m-d H:i:s');

        $mailTitle = "Masz wiadomość ze strony". env('APP_NAME')."<br/>";
        $message = "
        <b>Dane wiadomości:</b> $dateTime [$ip]<br/>
        <b>Tytuł wiadomości:</b> $title<br/>
        <b>Imię:</b> $userName<br/>
        <b>Adres email:</b> $email<br/>
        <b>Wiadomość:</b> $txt<br/>";

        Mail::to($adminEmail)->send(new ContactMail($message, $mailTitle, $email, $adminEmail));

        die('mail sent!');

    }

ContactMail.php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class ContactMail extends Mailable
{
    use Queueable, SerializesModels;

    public $message;
    public $title;
    public $sender;
    public $adminMail;
    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct(string $message, string $title, string $sender, string $adminMail)
    {
        $this->message = $message;
        $this->title = $title;
        $this->sender = $sender;
        $this->adminMail = $adminMail;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
{
    return $this->subject($this->title)
            ->from($this->sender)
            ->to($this->adminMail)
            ->replyTo($this->sender)
            ->view('mail.contactform', ['message' => $this->message]);
}

我的联系form.blade.php：

@section('content')
    {{ $message  }}
@endsection

运行脚本时出现错误：

htmlspecialchars（）期望参数1为字符串，指定对象（查看：> /var/www/project/resources/views/mail/contactform.blade.php）

我该如何修理？

需要build()类的

Mailable方法来配置邮件对象并返回self。因此，请在您的通话链末尾删除->send(..)通话：

public function build()
{
    return $this->subject($this->title)
            ->from($this->sender)
            ->to($this->adminMail)
            ->replyTo($this->sender)
            ->view('mail.contactform');
}

编辑：

htmlspecialchars（）期望参数1为字符串，指定对象（查看：> /var/www/project/resources/views/mail/contactform.blade.php）

问题出在您的邮件模板文件contactform.blade.php中-您不能在$message类中使用变量名Mailable，因为Laravel本身使用它来传递Mailable对象到模板（因此模板$message中包含对对象的引用，而不是对消息字符串的引用）。因此，您可以认为它是框架保留的。

要解决此问题，请将{{1}中的$message字段重命名为其他内容，例如$content（或$text，$body等） }类和ContactMail。

当我尝试在Laravel中发送电子邮件时，htmlspecialchars（）期望参数1为字符串
