You need to add another ampersand to the begining of booking[centre_id] like this: '&booking[centre_id]=' Sorry about that. (That's what comes of not testing my code!) I’m an idiot. You need to add another ampersand to the begining of booking[centre_id] like this: ‘&booking[centre_id]=’

Sorry about that. (That’s what comes of not testing my code!)

If you want to put multiple parameters in there; it's simple once you know how (but I took 15 minutes to get this working properly!): link_to_remote 'Check Availability', {:update => "check", :url => {:controller => "availability", :action => "check"}, :with => "'booking[date]=' + $F('booking_date') + 'booking[centre_id]=' + $F('booking_centre_id')"} The magic is once again in the :with, but convention leads you to believe that HTTP parameters should be passed with an ampersand, in Rails though it's the concatenation symbol + (plus). Hope that helps someone. Gav I’ve posted here since I used this page as the basis to get the first parameter in there; someone else Googling will hopefully reach here too.

link_to_remote ‘Check Availability’, {:update => “check”, :url => {:controller => “availability”, :action => “check”}, :with => “‘booking[date]=’ + $F(’booking_date’) + ‘booking[centre_id]=’ + $F(’booking_centre_id’)”}

I was wondering if there is a way to send multiple parameters with link_to_remote? I've been searching and trying, to no avail. Thanks, Adrian Hi.

shop_postcode should have returned the value. It looks like the new helper escapes the javascript….

Any ideas. If I put an alert for $F(’shop_postcode’), I get the value entered….
