I solved this using the optional   helper   Using the example here it would be      optional  usersType      A more complicated example would be if  like me  say you are trying to access a property of a null object  ie   users- gt type  in a view that is using old   helper   value     old  type   optional  users - gt type      Important to note that the brackets go around the object variable and not the whole thing if trying to access a property of the object   https   laravel com docs 5 8 helpers method-optional

usersType or       is working fine  The problem here is your foreach loop    foreach   usersType as  type        lt input type  checkbox  class  default-checkbox  gt   lt span gt     type- gt type    lt  span gt   amp nbsp    endforeach   I suggest you put this in an  if      if isset  usersType        foreach   usersType as  type            lt input type  checkbox  class  default-checkbox  gt   lt span gt     type- gt type    lt  span gt   amp nbsp        endforeach  endif   You can also use  forelse  Simple and easy    forelse   users as  user      lt li gt     user- gt name    lt  li gt   empty     lt p gt No users lt  p gt   endforelse
