Quick Submit Button Question

Rails
1

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 M.

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.

<%= 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)” %>

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?

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.

Thanks again,
