alabtechnosoft Posting the codes in couple hours...
Edit:- @alabtechnosoft I believe if we don't show email id to the restaurant, then it's okay too.
Go to resources/views/restaurantowner/viewOrder.blade.php
Go to line no 156 and press Ctrl + /. This is to hide a line of code.
Go to line no 157 and replace the code with the code below
<p><b>{{__('storeDashboard.ovContactNumber')}}: </b> {{ substr($order->user->phone, 0, 4) . "*****" . substr($order->user->phone, 8, 4) }}</p>
This will hide your phone number. Results in the image below.
Edit 2 - Play with 0,4 and 8,4 to properly align the mobile number with your country format.
