Hello

I have a view which have 2 radio buttons :

…

Actuel \<%= radio\_button\_tag(:actuel, value = "1", checked = false, options = {}) %\> Last \<%= radio\_button\_tag(:last, value = "1", checked = false, options = {}) %\> ...

I dont know how to proceed to control the status of my radio buttons.  
When I click on the first one, i want to put the 2nd unchecked. When I  
click on the 2nd one I want to uncheck the first one.

I know how to to it using html radio buttons + javascript. But using  
radio\_button\_tag I dont know how to proceed.  
Anyone can help me please?

thanks  
regards

I had put the radio buttons with the same name to be on the same group.

actuel \<%= radio\_button\_tag(:type\_recherche, value = "1", checked = false, options = {}) %\> last \<%= radio\_button\_tag(:type\_recherche, value = "2", checked = false, options = {}) %\>

To pass the values I use a link\_to\_remote:

\<%= link\_to\_remote “Rechercher”,  
:update =\> “resultlist”,  
:url =\> { :action =\> ‘rechercher’},  
:with =\> “…+ ‘&’ +  
‘type\_recherche=’ + $F(‘type\_recherche’)”,  
:complete =\> visual\_effect(:appear, ‘resultlist’, :duration =\> 1.00)  
%\>

In my controller when i try to access to the “type\_recherche” value (my  
2 radio buttons), I do this:

if params[:type\_recherche].nil?  
puts “1”  
@demand.type\_recherche = “0”  
else  
if params[:type\_recherche].to\_s == ‘null’  
@demand.type\_recherche = “0”  
else  
puts "6 -\> " + params[:type\_recherche].to\_s  
@demand.type\_recherche = params[:type\_recherche]  
end  
end

When i check the first radio it works fine. I receive the value “1”. But  
when i check the second radio button, i always receive null. It seems  
that the only radio button used is the first one.

Any idea about this problem.

Thanks
