Hi,  
I have multiple checkboxes in a table each one representing an item.  
They are like this:

[…]

\<%= check\_box "incidencias\_ids", incidencia.id %\> \<%=h incidencia.cliente.nombre %\> [...]

In the controller I have:

```
incidencias_ids = params[:incidencias_ids]
@incidencias = []
for id in incidencias_ids
  @incidencias << Incidencia.find_by_id(id)
end

```

I think this is enough to send all the checked checkboxes and manipulate  
them.  
But I don’t know how to send all the checkboxes to the controller! I  
know how to do it with link\_to\_remote but the answer is not displayed…

How I can do this with link\_to? Another way?

Try check\_box\_tag “incidencias\_ids[]”, incidencia.id

There’s more about why this works (ie what the [] are about) in the  
guide on form helpers at [guides.rubyonrails.org](http://guides.rubyonrails.org).
