Hi,

I have created a multiple selection listbox with  
rails, when I try to get the rows selected by user,  
rails send back only the first one, how can I get the  
other selected rows???

I created the listbox with the following function:

select\_tag(“form\_\_list1”,  
options\_for\_select([“A”,“B”,“C”,“D”], selected = “A”),  
html\_options = {“size” =\> 5, “multiple” =\> true})

What I get from params is :

!map:HashWithIndifferentAccess  
commit: Next  
action: index  
controller: cellfiles  
form\_\_list1: “A”

Thanks you very much

Saiho

I’m not sure, but try adding square brackets like this:

select\_tag(“form\_\_list1[]”,

hmm you might need to do something like form\_list1[] instead of just  
form\_list1 to get all the values into an array.

try that

Saiho,

Try this:

select\_tag(‘letters[]’, options\_for\_select([‘A’,‘B’,‘C’,‘D’], ‘A’),  
:size =\> 5, :multiple =\> true)

You need to add the [] to the name to get back an array of selected  
values.
