I’m trying do a search field using XHR form. Look this:

In view:  
\<% form\_tag ‘dub0’ %\>  
\<%= text\_field ‘dub1’, ‘dub2’ %\>  
\<%= submit\_to\_remote ‘btn\_search’, ‘search it’, :url =\> { :action =\>  
‘my\_search\_controller’ }, :update =\> ‘some\_div\_in\_my\_html’ %\>  
\<% end %\>

In controller:

@results = Model.find(:all, :conditions =\> [“some\_object = ?”,  
params[:dub3]]

My several questions are:

What’s need i put in ‘dub0’, is it a general id name (used to format  
html?)?  
What’s need i put in ‘dub1’ and ‘dub2’, is it the id of text\_field and  
…?  
What’s need i put in ‘dub3’, is it …?

## Thanks for your attention!

Strictly speaking you don’t need anything. However it’s nice to put  
the url/url parameters such that if javascript is not available the  
submit will go the the right place

and …?  
‘dub1’ should be the name of an instance variable and dub2 a method on  
that object. The text field’s initial value will be @dub1.dub2. I’d  
guess you actually want text\_field\_tag, not text\_field

Simple answer: look in development.log at the parameters that are  
passed.
