Looping over data submittted via jquery ajax routine with Coldfusion - coldfusion

Question

If FF firebug window, I see this is being passed to my coldfusion action page:
RowOrder[]=&RowOrder[]=row_5&RowOrder[]=row_2&RowOrder[]=row_1&RowOrder[]=row_3&RowOrder[]=row_4&RowOrder[]=row_6&RowOrder[]=row_7&RowOrder[]=row_8&RowOrder[]=row_11
Now I need to loop over this to get the updated sort order but due to the [], I'm having issues. How can I loop over this so that I can update my table??? I expected this to be the easy part but I'm obviously missing something.
+ I'm using the jquery plugin (http://www.isocra.com/2008/02/table-drag-and-drop-jquery-plugin/). +
Here is the code I'm using to loop over the submitted data:
<cfif StructKeyExists(form, "RowOrder")>
<!---<cfset variables.Order = ReReplaceNoCase(form.RowOrder, "(&){0,1}row_\[\]=", ",", "all") />--->
<cfset variables.Order = ReplaceNoCase(form["RowOrder[]"],"row_","","all")>
<cfloop from="1" to="#ListLen(variables.Order)#" index="index">
<cfquery name="qryOrder" datasource="#dsn#">
update SystemTypes
set Order = <cfqueryparam value="#index#" cfsqltype="cf_sql_integer" />
where WETypeNum = <cfqueryparam value="#ListGetAt(variables.Order, index)#" cfsqltype="cf_sql_integer" />
</cfquery>
</cfloop>
</cfif>
+ The ajax code I'm using is as follows:
$("#RowOrder").tableDnD({
onDrop: function(table, row) {
var RowOrderData = $.tableDnD.serialize();
$.ajax({
type: 'POST',
url: '../../ajax/UpdateListingOrder.cfm',
cache: false,
data: RowOrderData
});
}
});

Answer 1

How is the problem manifesting itself? Are you getting an error, the query is not executing, .. ?
Dump the FORM scope to verify the name of field being passed? It looks like FORM['RowOrder[]'] rather than form.RowOrder. In which case you would need to use:
<cfif StructKeyExists(form, "RowOrder[]")>
<cfset variables.Order = ReReplaceNoCase(form["RowOrder[]"], "(&){0,1}row_\[\]=", ",", "all") />
... rest of code ...
<cfelse>
oops, that variable name does not exist
</cfif>

Answer 2

Could you not match the number rather than replace?
I've done the regex match within the loop - You can then focus on just one part of the string at a time.
An an illustration of the approch:
<cfif structKeyExists(form, "rowOrder")>
<cfset data = listToArray(form.rowOrder, "&")/>
<cfif not arrayIsEmpty(data)>
<cfloop form="1" to="#arrayLen(data)#" index="index">
<cfset match = reFind("[1-9][0-9]+", data[index], 1, true)/>
<cfif arraySum(match)>
<cfset weTypeNumber = val(mid(data[index], match["pos"], match["len"]))/>
<cfquery name="qryOrder" datasource="#dsn#">
UPDATE
system_types
SET
order = <cfqueryparam cfsqltype="cf_sql_integer" value="#index#"/>
WHERE
we_type_num = <cfqueryparam cfsqltype="cf_sql_integer" value="#weTypeNumber#"/>
</cfquery>
</cfif>
</cfloop>
</cfif>
</cfif>
