Hi, Is there any trick to initializing the params hash via submit\_to\_remote()? I have a form with two submit methods - the regular, non-AJAX method, and the AJAX method. The regular method works like a champ. The submit\_to\_remote invokes the correct controller, but the params hash is empty except for the values for :action and :controller. I’d show my code, but it’s on an internal network and I can’t cut-and-paste. Thanks, -stan ---

Nothing magic here, just add the other parameters to the remote\_function or link\_to\_remote calls like this… \<%= link\_to\_remote “Link”, :update=\>‘updatediv’, :controller=\>‘controller’, :action=\>'action", :id=\>object.id, :other =\>‘other stuff’ %\> Things like other should now be in the params array for the recieving action \_Kevin ---

I thought the whole idea with submit\_to\_remote() was to make the contents of a form available to the controller in the params hash, just as if I had submitted it via non-AJAX form. Otherwise, I could have just called link\_to\_remote() instead. Any suggestions? ---

Kevin, Thanks. Believe it or not, it was a missing tag in the view that was preventing the form values from being passed. -stan Kevin O. wrote: > It would help if I actually read your question right. > > Take a close look at the API for submit\_to\_remote… if you also read > the docs for form\_remote\_tag.

It would help if I actually read your question right. Take a close look at the API for submit\_to\_remote… if you also read the docs for form\_remote\_tag. This indicates that there is a way to set it up to fallback to a normal submit if JS is disabled. You shouldn’t need wo submit mechanisms. I haven’t actually used this yet, so I can’t help much more than that. \_Kevin ---

Hi guys, i’ve got the same problem. But in my situation I have to send values of text-inputs via submit\_to\_remote() to my controller. I don’t know how to get the value of this text-input: \<%= text\_field\_with\_auto\_complete(:vorgang, :bez, {:value =\> ‘\*\*\*\*’}, {:skip\_style =\> true} ) %\> to my controller: def filterDatensatz() tmp = params[:vorgang][:bez] my\_redirect\_to(:action =\> ‘list’, :tmp =\> tmp) end params[:vorgang] is always nil. Can you help me? Greetings Chris ---

try something like this: rhtml: \<%= text\_field\_with\_auto\_complete :person, :nachname, {}, { :select =\> ‘name’, :after\_update\_element =\> “function(element,value) " + “{ " + remote\_function(:update=\>‘Kundendaten’, :url=\>{:action=\>:update\_kundendaten}, :with=\>”‘adr\_id=’+value.id”) + “;” + “}” } %\> controller: def update\_kundendaten #params[:adr\_id] should be ok in controller end but with this solution i have the problem that the autocomplete is only working on IE. FF wont show the autocomplete popup. ☹ HTH On 12 Jan., 11:42, Christian R. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)
