I have this:

\<%= start\_form\_tag({:action =\> ‘search’}, :method =\> “GET”)%\>

 selected="selected"\<%end%\>\>Sort Alphabetically selected="selected"\<%end%\>\>Sort by Rating \<%= end\_form\_tag %\>

And I there are some parameters that have previously been set that I  
would like to pass to the method here also.

I’ve tried doing the following:

\<%= start\_form\_tag({:action =\> ‘search’, :query =\> params[:query]},  
:method =\> “GET”)%\>

And also:

\<%= start\_form\_tag({:action =\> ‘search’, :params =\> {:query =\>  
params[:query]} }, :method =\> “GET”)%\>

To no avail.

one way is to put the previously set params as hidden fields in this  
form.

Here’s a link\_to\_remote tag I have which sends some parameters up to the  
controller:

\<%= link\_to\_remote(image\_tag(photo.sizes[0] [‘source’]),  
:with =\> “'bigpic=”+ photo.sizes[3][‘source’] + “&flickrurl=”+  
photo.owner.photos\_url + photo.id + “'”,  
:before =\> %(Element.hide(‘bigphoto’)),  
:update =\> ‘bigphoto’,  
:complete =\> visual\_effect(:toggle\_blind, ‘bigphoto’, :duration =\>  
1),  
:url =\> {:action =\> “see\_picture”}) %\>

The :with =\> part is where you send the parameters. I think you can use  
it  
with form tags as well, but I’m not sure…

In the :with part above, I have a parameter named “bigpic” and another  
named  
“flickrurl” seperated by an &.

In the controller you view the parameters like this:

```
@url = params['bigpic']
@flickrurl = params['flickrurl']

```

I’m not sure this will help in your case, but it sounds similar.

Sorry in advance if it doesn’t do any good! 🙂

I’d have to guess that the \* in \*parameters\_for\_url indicates that you  
can  
have 0 or more. But that’s just a guess. The Rails API documentation  
leaves a little to be desired. 🙂

Hrmm.

I’ve looked in the API and it says:

form\_tag(url\_for\_options = {}, options = {}, \*parameters\_for\_url, &proc)

so if I bracket :method =\> “GET” and then put my parameters in? What  
does the ‘\*’ symbol mean in this case though?
