Question

I’ve been searching with not much luck for this… I have the code

url = params[:url];
if url == "" 
    @myString = "No URL specified, cannot continue"
else
=begin
    DO SOME STUFFS....
=end
end

But the DO SOME STUFFS is still getting called. I have my index page which I perform actions on the _GET variables. I’d like to load the index page without the parameters in the URL. How do I check if they are set – if they’re not, then display a message. If they are, process the requests…

Thanks!

Answer 1

url = params[:url]
if url
  # do stuff
else
  @my_string = "No URL specified, cannot continue"
end

params[:url] will be nil if not provided. nil evaluates false in a conditional.
