Quick Submit Button Question...

Hello, Can I pass a variable from a submit button only? I have a form that the user fills out and I need two different submit buttons - one for 'sync' and one for 'full push'. I was thinking I could add some sort of param to the button, but it's not working... is there a way to do this? I have this:

<%= submit_tag 'push to Exchange', :name => "rad", :id => "0", :onclick => "doClick(this)" %>

<%= submit_tag 'force full push', :name => "radtwo", :full => "full", :onclick => "doClick(this)" %>

I tried to add param[:full], but it doesn't work. Any suggestions?

Thanks, - Jeff Miller

check your params--you might find it's already in there.

Unless you gave a :name => nil option to your submit_tag, you can test params[:commit] for the button label (or, I think, supply your own :value => 'sync' or :value => 'full')

I've used this to give both a "Create" and a "Create and Add Child" button to a form that changed where you were redirected on success.

I'm a newbie myself, but suspect that submit_tag can not be made to do this. To pass arbitrary parameters to your controller from a form you specify them on the form_for call.

One option that comes to mind is to give the user a drop-down to select which of the two types of submits they want to do. I don't suppose that appeals?

<%= submit_tag 'force full push', :name => "radtwo", :full => "full", :onclick => "doClick(this)" %>

You should specify params[:full] at function doClick(this). But if you put 2 submit_tag buttons there, it's nasty way. Another way is :

<%= submit_tag 'push to Exchange', :name => "rad", :id => "0", :onclick => "doClick(this)" %>

<%= button_to_function 'force full push', {:name => "radtwo", :full => "full"}, :onclick => "doClick(this)" %>

Another way is : <%= button_to "push to Exchange", {:action=>'go',:name => "rad", :id => "0"}, :onclick => "doClick(this)" %>

<%= button_to "force full push", {:action => 'where', :name => "radtwo", :full => "full"}, :onclick => "doClick(this)" %>

Thanks guys, I ended up passing it through Javascript, like the last suggestion. And yes, it turns out that HTML submit buttons cannot pass variables themselves, as they just initiate the post.
