You can send a parameter in a image\_submit\_tag?

I have two buttons on a form and I do not know how to differentiate  
which has been pressed.

\<=% Image\_submit\_tag ("…/ images / incluir.gif “: op =\>” addImage “)%\>  
\<=% Image\_submit\_tag (”…/ images / eliminar.gif “: op =\>” delImage ")%\>

Thank you

Ramon – I just had a similar case with submit\_tag (which creates a  
submit button and calls the action associated with the form). I  
solved the problem by adding a :name parameter as one of the optional  
parameters, then testing for in in the submit action associated with  
the form. (I am not sure if :name is special, I was just copying an  
example I found :-). , for example

\<=% Image\_submit\_tag ("…/ images / eliminar.gif ", :name =\>  
“del\_image”) %\>

then in the controller, if your form action was called “manage\_image”,  
you can test for the presence of the specific name value in the params  
hash, like so:

def manage\_image  
if params[‘del\_image’] ##  
… code to delete the image …  
else  
… code to add the image …  
end  
end

Here’s the link I found with a more complete description of the  
solution:
