2 session arrays combined into 1
Hi everyone, I'm stuck on this and it must be so simple but can't get my head round it. I have 2 different shopping cart arrays going at the same time because some products are handled differently to 'normal' products, know it's unusual but this is how it had to be. I also need to have a 3rd cart array which combines all items form Cart 1 and Cart 2 into 1 single array. Each cart array is actually a new structure to hold items with ItemName and ItemID. Is it possible to 'dynamically' populate cart 3 with the contents of cart 1 and 2 so if I add an item to cart 1 it'll automatically be shown in cart 3, or if I add one to Cart 2 it'll also be shown in cart 3. All these arrays with structures are store in SESSION. Hope that all makes sense. Any help would be greatly appreciated. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:346654 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
CF 9, WebService, arrays, and objects
So, I have this method setup
remote com.foo.StateDTO[] function getAllStates() {}
1) if I invoke via web browser via
http://myurl/myservice.cfc?wsdlmethod=getAllStates
it works a treat
2) if I use cfinvoke method=getAllStates webservice=
http://myurl/myservice.cfc?wsdl; I get the below error
3) if I use Flex to hit the WSDL, I get the same error
Now, reading in docs and a few blogs, returning a typed array is supposed to
work, but it ain't captain! Any hints or thoughts?
If I replace the return type with array, it all works, but hey, the WSDL
says its any type.
The error:

RE: Storing Arrays or Structures in a database
Arrays are easy as you can simply use Arraytolist() to convert it to a delimited text string and then use ListtoArray() to convert back once you get it out. Though, CF has some really nice list functions, so you might not even have to do that. Also, select boxes return comma separated lists back to CF when a form is submitted (ditto for checkboxes with the same name)... So that might work in your favor. For structures though, WDDX is your friend, and quite easy to do... Try cfwddx action=CFML2WDDX input=#workweek# output=workweekXML Then stuff workweekXML into the database field.

Re: Storing Arrays or Structures in a database
Keep in mind that WDDX adds quite a bit of extra stuff around your data as compared to JSON. For example, take this ColdFusion array: cfset myArray = [John,Paul,George,Ringo] Here is the serialized JSON version: [John,Paul,George,Ringo] Here is the WDDX version: wddxPacket version='1.0'header/dataarray length='4'stringJohn/stringstringPaul/stringstringGeorge/stringstringRingo/string/array/data/wddxPacket The larger the array or structure, the bigger the bloat from WDDX, and the more database space required to store it. This needs to be considered when designing your database columns. HTH, Carl On 4/6/2011 10:52 AM, Michael Grant wrote: Serialize them as JSON or WDDX and store them as text.

Re: Storing Arrays or Structures in a database
Another way to do it is to serialize the object in a base64 string.
I've had some great success using this method to persist complex
objects to the database.
cfscript
function serializeObject(object){
var local = structNew();
local.byteOut = createObject(java, java.io.ByteArrayOutputStream);
local.byteOut.init();
local.objOut= createObject(java, java.io.ObjectOutputStream);
local.objOut.init(local.byteOut);
local.objOut.writeObject(arguments.object);
local.objOut.close();
return toBase64(local.byteOut.toByteArray());
}
function deserializeObject(objectString){
var local = structNew();
local.inputStream = createObject(java,
java.io.ByteArrayInputStream);
local.objIn = createObject(java, java.io.ObjectInputStream);
local.returnObj = ;
local.inputStream.init(toBinary(arguments.objectString));
local.objIn.init(local.inputStream);
local.returnObj = local.objIn.readObject();
local.objIn.close();
return local.returnObj;
}
/cfscript
I've been using this in http://sessionswap.riaforge.org/ for a long time.

Just make sure that your db field can handle a decent sized chunk of data,
especially if you are allowing user defined data in this column as the WDDX
format can get kinda bloated.

RE: arrays and looping around
No you do not need to declare an array in this case. It is not actually an array; it is just called array notation because it is the same syntax you would use on an array. FORM is actually a predefined structure/collection (aka 'scope')... such as URL or VARIABLES scopes Most variables that you can reference as scope.variable, you can reference as scope[variable] In your last example: cfset LegalProteinSequence_#LoopCount# = ...

Re: Looping through arrays with structures
No worries. An honest mistake. I've actually never used the Array attribute since I've been looping this way for 10 years. And unless it's inherently faster (which I doubt) I suspect I never will. I actually prefer my loops to use an int as the index. That was I've always got an easily available currentrow-like variable.

Re: Checking arrays for any values
You can do listFind(arrayToList(aYourArray),1) for the bit datatypes. I'm not sure what the performance of that will be if your array is very large, though. For the string array, you can do NOT listFind(arrayToList(aYourArray,)) I'm not sure if that logic is exactly correct, but it should get you going down the right path.

Thanks in advance. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:336831 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Re: Arrays - humbug! - Part 2
Larry, Not sure exactly what you're going for. But rather than go into array usage (and looping a collection), which you can probably learn better elsewhere, maybe there's a simpler way to attack the problem. In the end, you seem to simply want to go over a query result: cfquery name=GetLats datasource=#SESSION.ds# SELECT tblLaterals.latID, tblLaterals.lateralID, tblLaterals.Why, [FirstName] Chr(32) [LastName] AS Who, tblPlayers.Title, tblPlayers.TX, tblPlayers.FAX, tblPlayers.Email, tblLaterals.DateSent FROM tblLaterals LEFT JOIN tblPlayers ON tblLaterals.lateralID = tblPlayers.playerID WHERE tblLaterals.MasterID=#SESSION. Report.MasterID# ORDER BY [FirstName] Chr(32) [LastName]; /cfquery ... and output it onto the page. Now, I'm assuming that you're stuffing the results into the session scope because you need to use it more than one place. But I can't see why you need to create the array or do all that looping. Can't you simply place the query result into the session scope: cfset session.Report.Lats = getLats / ... then output it on the page: cfif session.Report.Lats.recordCount GT 0 cfoutput query=session.Report.Lats ... and built your list item here. /cfoutput /cfif Or have I missed what you're going for? -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 ~| Want to reach the ColdFusion community with something they want?

Re: Arrays - humbug! - Part 2
For further manipulation, it's also sometimes handy to remember that a query object is essentially a struct of arrays, with the selected columns at struct keys. So you can also do things like: cfif Session.Report.lats.recordCount GT 0 cfloop from=1 to #Session.Report.lats.recordCount# index=i do something with Session.Report.lats.Why[i] /cfloop /cfif Of course, you can always just cfloop query=Session.Report.lats and avoid the use of the index. Just thought I'd point out that you can access individual records in the array for each column with array notation. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 ~| Want to reach the ColdFusion community with something they want?

Sorting 2d arrays
I have an app currently that needs a list sorted alphabetically with alpha-numeric chars. I am using a query and then narrowing the results into an array and then creating two lists for an autosuggest. Imagine searching by an alphanumeric ID (not SQL ID) and also by the description: 1234ii -- apple 1234i -- banana 123x -- orange orange -- 123x banana -- 1234i apple -- 1234ii Then once the sorting is completed, I need to grab the unique ID (incremental SQL ID) from the original array again and then use that to update the database. Currently I am building the array, sorting with quickSort2D(), building the list and then to grab the SQL ID from the array again I use a function that loops through the array to match ID ' -- ' text or vice versa. This takes about 20 seconds to build. Also, this is something that will change per page refresh so storing anything in memory is pretty much nil. Any thoughts on simplifying the process? Anyone have experience with speeding up array processes? ~| Want to reach the ColdFusion community with something they want?

RE: Sorting 2d arrays
Tony, Probably a ton of ways to do this. Would this get you what you want?: (note: the below would be for oracle, you need + instead of || for Sql server - not sure about what db you're using) cfquery datasource=whatever name=qMySuggestions select sql_id, alphanumeric_id || description as auto_suggest_descr from mytable union select sql_id, description || alphanumeric_id as auto_suggest_descr from mytable order by augo_suggest_descr /cfquery Now you should have a query with the results in the order you want them with the original sql_id also there. Now instead of looping through an array to do a match, you simply do a query of query: cfquery name=qFindMatch dbtype=query SELECT sql_id FROM qMySuggestions WHERE (put your condition here to find a match) /cfquery qFindMatch.sql_id is the record you want.

Re: Sorting 2d arrays
Okay I figured it was going to be a query based solution.

Re: Sorting 2d arrays
Sorry, forgot to mention that the query above just returns the ASCII chars. Then I use a different query to classify the first char: DECLARE @ErrorNum INT SET @ErrorNum = 1 DECLARE @ TABLE ( [Id]INT, [Name] VARCHAR(255), [Number]VARCHAR(255), [_] VARCHAR(255), [_] VARCHAR(255), [SortOrder] TINYINT) ERT INTO@ SELECT a.[Id], a.[Name], CASE WHEN ISNULL(a.[Number], '') = '' THEN '' ELSE a.[Number] END, CASE WHEN ISNULL(a.[Number], '') = '' THEN a.[Name] ELSE a.[Name] + ' -- ' + a.[Number] END, CASE WHEN ISNULL(a.[Number], '') = '' THEN '' ELSE a.[Number] + ' -- ' + a.[Name] END, CASE WHEN ASCII(LEFT(a.[Name], 1)) BETWEEN 0 AND 47 THEN 1 -- symbols ordered first WHEN ASCII(LEFT(a.[Name], 1)) BETWEEN 48 AND 57 THEN 2 -- numbers ordered second WHEN ASCII(LEFT(a.[Name], 1)) BETWEEN 58 AND 64 THEN 1 -- symbols ordered first WHEN ASCII(LEFT(a.[Name], 1)) BETWEEN 65 AND 90 THEN 3 -- letters ordered third WHEN ASCII(LEFT(a.[Name], 1)) BETWEEN 91 AND 96 THEN 1 -- symbols ordered first WHEN ASCII(LEFT(a.[Name], 1)) BETWEEN 97 AND 122 THEN 3 -- letters ordered third ELSE 1 END FROM[dbo].[] AS a WHERE a.[Name] 'All s' There is more but you get the idea.

Outputting implicit arrays?
I thought this would be something fun to discuss. How do you output implicit
arrays?
here is the array (we will use a navigation as an example):
navigation = [
{name=home,href=index.cfm,class=nav},
{name=contact,href=contact.cfm,class=nav}
];

Re: Append Arrays with Structures
it's been said over and over in this thread. arrayAppend() returns a boolean. if you do cfset session.pageList = arrayAppend(myArray, structNew()) /, you're essentially setting the value of session.pageList to true. Then, when you try to run an array function on session.pageList, you get the error because it's not an array. it's a boolean whose value is true. read thru the replies and you'll see. you're asking for help and people are trying to give it to you, but you don't seem to want to take it. cfset arrayAppend(myArray, structNew()) /. that will fix your problems.

All speculation (though I'm sure someone here knows the answer for sure) but: It may not be due to the java link. I found a reference that says ArrayAppend returned a boolean back in the days of CF 4.5. So it may just be a carry over.

Re: Append Arrays with Structures
Nowhere states that the function returns a boolean ;) But it is odd, indeed, why return anything at all. I've done it myself in functions and justified it with 'One day I may have some logic that returns false and then the calling code that is checking for the boolean wont break. CF functions have traditionally returned a Boolean value even when this value doesn't indicate anything meaningful.

Re: Append Arrays with Structures
Ah, we are at cross wires! I was citing the java method as a possible reason for the function only ever returning true (or my suspicion that it never returns false, in response to Adrian's question) - not for it returning a boolean (which of course it does). Perhaps pre-6 it did sometimes return false, though as David points out, CF has traditionally followed this pattern so quite probably not. The docs may have changed their wording to reflect the wording in the javadocs, if indeed that is the method that is being used. Anyways, I wonder if the OP has found his solution yet ;) Dominic 2009/3/11 C S cfsearch...@yahoo.com: No, I just meant that the function returning a boolean at all probably had nothing to do with the java link.

Re: Arrays
Interesting Will. So does your outer-most structure have some sort of incremental key? Personally an array of structs seems easier to me because the array implies a series of something. As far as updating and the code to deal with them it is pretty much 6 or 1/2 dozen I would think. I have a timeAdded key which I sort on using structSort(). cfset keyArray = structSort(cart, numeric, desc, timeAdded) Then use the resulting array to loop over the cart. cfloop from=1 to=#arrayLen(keyArray)# index=thisKey pSKU: #keyArray[thisKey]# | Time Added: #cart[keyArray[thisKey]].timeAdded# | Price: #cart[keyArray[thisKey]].price#/p /cfloop Will ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:319952 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Re: Arrays
Hey Jason, if you don't already know which position in the array the item id is located, then you'll need to loop through the array and find it. Once found, you are actually dealing with a structure, so updating is just a simple cfset. Something like this (assuming item id is in session and new zoneCost coming from a form variable): cfloop from=1 to=#arrayLen(Items)# index=i cfif Items[i].ID eq session.ID cfset Items[i].zoneCost = form.zoneCost /cfif cfloop Does that make sense? I'm hoping I understand your question correctly.

Re: Arrays
An array of structs is effectively a query. And having it in query form generally makes it easier to handle - much more powerful sorting and filtering (using QoQ). ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:319043 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
RE: Arrays
Your point about being able to use QoQ is a good one. It turns out that a query is actually implemented as a struct of arrays (where the struct key is the name of the column), and the most annoying thing about that is having to index the arrays by current row all of the time, vs a true array of structs, where each struct stands on its own (so you can pass the struct representing one row/object to a function, for example). It can also be handy to be able to put different fields/data in each struct, and the true query model stinks for that.

Re: Multi-dimentions Arrays
Hi Charlie, many thanks for your message. Yes, your tutorial is excellent for what I need to do; part3 (an array of structures) is most relevant. I am trying to adapt it to my problem, which is as follows. There can be any number of (i.e. 2-digit) projects, each has a few overhead codes with a number of financial years (up to 6), each financial year will have a few types of costs (4) and each of these costs have to be divided between 12 months. So, I think I need an array of projects, which has structures of financial years and then another level of structures for monthly amounts? Does that sound reasonable? e.g. cfset projects[finYear][month] = StructNew(). Please advise. Regards, Kamru i did a 3 part tutorial on arrays and structures that might be of some help. http://tutorial171.easycfm.com/ http://tutorial172.easycfm.com/ http://tutorial173.easycfm.com/ check 'em out and see if they help wrap your brain around the concepts.
