@sr57 So what should I do?

@Sinnbeck

@component('mail::message')
<h1>Hello, {{ $companyholder_name }}!</h1>
<p>You received new {{ $review_stars }} star review from {{ $author_name }} for your company in {{ config('app.name') }}.</p>
<a href="{{ route('review.index', ['review' => $review_id]) }}"><button>Give it a read</button></a>
@endcomponent

I can try to rename it.

@Sinnbeck Still getting the same error after renaming it.

@Laralex Can you try this?

 $this->markdown('emails.sendcompanynotificationfornewreview', ['review_id' => $this->review_id, 'review_stars' => $this->stars, 'author_name' => $this->author_name, 'companyholder_name' => $this->companyholder_name]);
dd($this->buildMarkdownView());

@Laralex Yes it does not use markdown, so you need to use a regular view with css etc.

@Sinnbeck But my other emails are using markdown and I didn't faced any problems. What is causing the problem here?

@Laralex That is what we are trying to find out. I dont think anyone has spotted the problem yet, so we need to do some debugging.

@Sinnbeck OK, after chaning to ->view() I received an email but there is nothing inside. The email header (title) is correct but there is nothing inside the email contents. What can I do?

@Laralex Sounds like that file is returning nothing. Did you perhaps forget .blade. in the file name or something?

@Sinnbeck It's named newreview.blade.php.

I'm sharing app/Mail/SendCompanyNotificationForNewReview.php again

namespace App\Mail;

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

class SendCompanyNotificationForNewReview extends Mailable
{
    use Queueable, SerializesModels;

    public $review_id;
    public $stars;
    public $author_name;
    public $companyholder_name;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct($review_id, $stars, $author_name, $companyholder_name)
    {
        $this->review_id = $review_id;
        $this->stars = $stars;
        $this->author_name = $author_name;
        $this->companyholder_name = $companyholder_name;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->subject('New ' . $this->stars . ' star review for your website in ' . config('app.name'))
        ->view('emails.newreview', ['review_id' => $this->review_id, 'review_stars' => $this->stars, 'author_name' => $this->author_name, 'companyholder_name' => $this->companyholder_name]);
    }
}

@Laralex Did you try the debugging I suggested above?

@Sinnbeck

return $this->subject('New ' . $this->stars . ' star review for your website in ' . config('app.name'))
        ->markdown('emails.newreview', [
            'review_id' => $this->review_id, 
            'review_stars' => $this->stars, 
            'author_name' => $this->author_name, 
            'companyholder_name' => $this->companyholder_name
        ]);
        dd($this->buildMarkdownView());

returns the same error.

DOMDocument::loadHTML(): Argument #1 ($source) must not be empty 

@Laralex Does it work if you set it to use any of your other markdown email templates? I am trying to figure out if the error is with the mailable or the template.

@Sinnbeck When I use other markdown email template it's not showing any error. Shouldn't it die&dump when we have dd($this->buildMarkdownView()) in the SendCompanyNotificationForNewReview.php ?

@Laralex Ah just noticed you did something else than suggested. You are returning before the dd. In php you cannot run any code after a return.

But interesting that it works with another template. Can you try creating a new file to test with, and just write some test text in it to see if it work

This works..

Just did some digging around, and the error is most likely due to invalid html.. This isnt valid as you cannot have a button inside an a tag. Remove this line and I am sure the error is gone.

<a href="{{ route('review.index', ['review' => $review_id]) }}"><button>Give it a read</button></a>

Instead use the button component: https://laravel.com/docs/8.x/mail#button-component

@Sinnbeck Ok, so.

$this->subject('New ' . $this->stars . ' star review for your website in ' . config('app.name'))
        ->view('emails.newreview', [
            'review_id' => $this->review_id, 
            'review_stars' => $this->stars, 
            'author_name' => $this->author_name, 
            'companyholder_name' => $this->companyholder_name
        ]);
        dd($this->buildMarkdownView());

this is returning

View [] not found. 

and this

$this->subject('New ' . $this->stars . ' star review for your website in ' . config('app.name'))
        ->markdown('emails.newreview', [
            'review_id' => $this->review_id, 
            'review_stars' => $this->stars, 
            'author_name' => $this->author_name, 
            'companyholder_name' => $this->companyholder_name
        ]);
        dd($this->buildMarkdownView())

is returning the same DOM error
