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
        });
    }   
});

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>
