AJAX :: Passing Values As Array To Php File?

Over in this thread, someone suggested a solution to an issue I was having when attempting to send multiple values per select box to a php file. You can review my original post here for reference:

[URL]

The problem is, when I change my form names to be arrays (i.e. age[] vs. age), it broke my Ajax script. I copied the original script from w3schools, and I don't really know much about javascript/Ajax to know what it is that I need to do to fix this.

Here is my Ajax script:

Code:

<script type="text/javascript">
function showResult(name,age,gender,ethnicity,facility)
{
if (name=="" && age=="" && gender=="" && ethnicity=="" && facility=="")

[Code]....

Now, when I leave my field names without the [], the script works MAHvalously. However, as soon as I add in the [] to the field names, and also update the vars to be age[].value instead of age.value, etc, it breaks.
