Question

"fnServerParams": function (aoData) {
            var sReportType = (jQuery('#report_type').val() == "") ? "Downline" : jQuery('#report_type').val();
            var aRankID = (jQuery('#rank_id').val() == null) ? [] : jQuery('#rank_id').val();

            aoData.push({
                "name": "report_type",
                "value": sReportType,
                "name": "rankid",
                "value": aRankID.join(',')
            });
        },

aRankID should either be an empty array or populated with the values from a multi select box.

When I first load the page here is what firebug returns.

>>> jQuery('#rank_id').val();
null

After I make some selections here is what it returns.

>>> jQuery('#rank_id').val();
["1", "2", "3"]

I must be missing something because it is causing my ajax page to crash. And I need to use.join because my ajax page is expecting a string.

Any help is appreciated!

Try this:

 "fnServerParams": function (aoData) {
        aoData.push({
            "name": "report_type",
            "value": jQuery('#report_type').val() || "Downline",
            "name": "rankid",
            "value": (jQuery('#rank_id').val() || []).join(",")
        });
  }
