Passing Arrays to a cgi script

TS 6.5
Solaris 9

I've created a FormAPI script to pass an array to a cgi. However, the cgi can't seem to pick up the javascript array. Are we only allowed to pass strings to a cgi? in the code below 'fieldArray' is not showing up as one of my parameters that have been passed. Any thoughts?

javascript code

var dcrFields = new Array();
dcrFields[0] = "/site_nav/brand/leftImage";
dcrFields[1] = "/site_nav/brand/leftImageAlt";
..........
...........
var params = new Object();
params.fieldArray = dcrFields ;
...........

IWDatacapture.callServer("http://"+server+"/iw-bin/kpinfo/getDefaultValues.ipl", params);

-----------------------------------------------------------

perl code (CGI)

use CGI;
my $in = new CGI;

foreach my $key ($in->param) {
debug("key: " . $key);
}

Your code does not seem to be getting any value at all.. Were you able to pass a simple variable using the same code?

I am passing 'params' and the cgi is able to print out all the variables that are part of params. However, when I pass an Array object the cgi does not recognize the array.

Do you know how to pass an array from a FormAPI script to a cgi script?

AFAIK, you can only pass name/value pairs and not a complete array. Now there are some examples on DevNet for passing arrays back from callserver to FormAPI, but I have never see anything going from FormAPI to callserver.

You can make a list (say comma separated) and pass it and then parse that back into an array

Can you make the array declaration / definition into a string - pass that to the CGI and then have the CGI script dump the string into a script section of the "output" that would normally be rendered by the browser?

I ended up doing exactly that. Turning the array into a comma separated string. That worked! Thanks!
