laravel 邮件发送动态主题

Question

我可以使用 laravel 发送邮件，如下所示，但我想要的是这个；我想让主题部分动态化，我该如何实现？

$sendAdmin['sendAdmin'] = $data;
        Mail::to('hello@word.com')->send(new \App\Mail\ContactMail($sendAdmin));

class ContactMail extends Mailable
{
    use Queueable, SerializesModels;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public $details = [];

    public function __construct($details)
    {
        $this->details = $details;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {

        return $this->subject('Hello Mail')->view('email.contactform');
    }
}

Answer 1

假设主题来自您的$details 数组，这很简单：

public function build()
{
    return $this->subject($this->details['subject'])->view('email.contactform');
}
