Passing variables to email footer in Laravel - laravel

Question

I would like to show a disclaimer in the footer saying
This email was sent to {recipients email address}.
but i can't figure out how i can get the email address into the standard footer blade.
Here is what I have:
In my notification component I make the following call with $rcp_email having the email address of the recipient:
return (new MailMessage)
->subject('Contact Form Submitted')
->markdown('emails.generic.contactform', [
'first_name' => $this->first_name,
'message' => $this->message,
'rcp_email' => $this->rcp_email,
'url_security_issue' => $url_security_issue,
]);
The emails.generic.contactform looks like this
#extends('emails.main')
#section('content')
(body of email)
#endsection
emails.main looks like this
#component('mail::message')
#yield('content')
#if (isset($unsubscribe_url))
(html code for unsubscribe)
#endif
#endcomponent
the standard vendor\mail\html\message blade looks like this:
#component('mail::layout')
{{-- Header --}}
#slot('header')
#component('mail::header', ['url' => config('app.front_end_url'), 'logo' => asset('logo-image-white-circular-background.png')])
{{ config('app.name') }}
#endcomponent
#endslot
{{-- Body --}}
{{ $slot }}
{{-- Subcopy --}}
#isset($subcopy)
#slot('subcopy')
#component('mail::subcopy')
{{ $subcopy }}
#endcomponent
#endslot
#endisset
{{-- Footer --}}
#slot('footer')
#component('mail::footer')
© {{ date('Y') }} {{ config('app.name') }}. #lang('All rights reserved.')
#endcomponent
#endslot
#endcomponent
I traced each level of blade and $rcp_email is first of all not availble in the message blade. I tried to pass it on by changing the first line of emails.main to
#component('mail::message', ['rcp_email' => $rcp_email])
but in either case when i try to use the variable in the message blade, i get the error Undefined variable: rcp_email
In an ideal case, I would want to add the html code and make use of the variable in the actual footer blade, but I don't know if that's possible.
I would much appreciate if there is any hints/any docus or articles you can share that describes in depth how this works?
Thanks,
Goppi

Answer 1

hopefully this helps for others with issue
From what I did, when you use #component('mail::message', ['rcp_email' => $rcp_email]) it will pass the variable $rcp_email to the message blade.
Here change your message blade #component('mail::footer') to #component('mail::footer', ['rcp_email' => $rcp_email]) to pass it again to your footer blade.
In footer blade access the variable like {{$rcp_email}}
so example would be <p>sent to {{$rcp_email}}</p>
Also as a note, when passing the variable like ['name' => $variable] it uses the name as the variable in the next blade. so here you would access it like $name

Thanks #Jack C - your solution didn't work for me back then as you can see from my original post. I tried to pass rcp_email on to the message blade using
#component('mail::message', ['rcp_email' => $rcp_email])
and when I tested $rcp_email within the message blade, it came back with undefined variable. That said, I didn't figure out why it wasn't working, but I used #component with variables for other blades without issues. Perhaps it didn't work due to caching issue.
The solution that I came up with back then opened itself up once I decided not to use the standard email template, but design my own.
The emails.generic.contactform changed as follows:
#extends('emails.layout.layout')
#section('content')
{{-- body of email --}}
#endsection
The emails.layout.layout blade looks like this:
#component('mail::layout')
{{-- Content --}}
{{-- Footer --}}
#slot('footer')
#component('mail::footer')
{{ $recipient ?? '' }}
#endcomponent
#endslot
to summarize, my understanding on how to pass variables between blades is as follows:
extend - extends allows the layout blade to use all variables with the same names as the extended blade.
#extends('layout')
components have no access to the variables of the parent blade. Instead they need to be passed on. There are two ways to pass them on: as one or more variables or as a slot. In the example below $name is available within the component footer.
#component('footer', ['name' => $rcp_email])
#endcomponent
component - the second way is as a slot. In the example below the variable $slot would contain the email address.
#component('footer')
{{ $rcp_email }}
#endcomponent
