Re: cannot figure out how to handle multi checkbox


I had seen that, but it's not clear to me (and some of the people who 
commented on there agree with me).  As I said, my checkboxes are not 
tied to a model.

Re: cannot figure out how to handle multi checkbox


As I find somewhere on the net:

View (as many times as needed):

        <input id="item_selected_keywords" name="selected_keywords[]"
        type="checkbox" value="exterior" />

Controller:

        selected_keywords = params[:selected_keywords]
        @item.keywords = selected_keywords.join(" ")

Re: cannot figure out how to handle multi checkbox

Actually, I wanted the results in a collection or array to iterate over 
in my next view, so this is what worked for that last line in the 
controller:

@item.keywords = selected_keywords

I was just trying really hard to use the Rails view helpers for a 
checkbox, but if I have to use straight HTML, then by no means am I 
opposed.  It just seems like one of those Rails helpers should work for 
me, but I figure it's because I don't understand them and when I look at 
the examples in the API docs, they don't seem to be applicable for my 
case (or I just don't get them).

Thanks...
