Answer 1

Your code is wrong, you are missing quotation marks. So it is trying to access the value of the array using a constant as the key, rather than a string. The below should work.

  <h3> {{trans('site.blockchain.send')}} <span style="color:red">{{ $form_data['amount']}} </span>BTC <br> {{trans('site.blockchain.to')}} <span style="color:red">{{ $form_data['sendto']}} </span> </h3> <br> <br> <h2>{{trans('site.blockchain.scan')}}</h2> {!! $form_data['code'] !!} <br> <br> <h3 style="color: red;">** {{trans('site.blockchain.confirmations')}}</h3>
