[Rails-spinoffs] Re: How do I post an array to PHP using Ajax.Updater?

[WebbedIT]

The array wouldn't go at all where it should have posted

filters=arrayString&paramsVar1=Value1&paramsVar2=value2

it just kept posting

&paramsVar1=Value1&paramsVar2=value2

I have now experimented further and have created a hash which I then
passed through toJson() before posting to PHP where I used
json_decode().  So whilst the initial issue is not resolved (it
probably can't be as I don't think you can pass through an associative
array) I have managed to get my code working.

Thanks,

Paul.
