Question

I’m trying to delete several files based on a list but I’m having problems getting the params from the chekcbox’s

This is my list.haml:

%form(method="post" action="/selection" enctype="multipart/form-data")
        -   @files.each do |file|
            %br
            %input{:type => "checkbox", :name => "checkbox[]", :value => "#{file}" }
            =file
        %br
        %input(type='submit' value="Delete Selected Files")

Now, for now I was just trying to see what I get in params, so I can later deal with how to delete this list of files.

params.inspect

“Gives me” ≃> {“checkbox”=>[“yet_another_file.txt”, “file1”, “file2”]}

But I can’t figure out how do I put this into an Array so I can do something like

var.each do |c|
    puts c
end

I tried var = params[:checkbox] but var is empty, does anyone now how can I do this?

Thanks

You should use var = params["checkbox"], since the params key is not a symbol, but a string.
