RE: first time array
I am missing the form but I think it is probably something like a loop over 4 textboxes that have the same name. In your action page (code posted) you only create one record, with a comma delimited list of values in it. I suppose you want each line in the form to be a record and create an array from it? Here it comes: The form: Issue Title Date Publication The action page: Record #i# #cassettes_Array[i][j]# The first loop loops the rows, the second loops the columns.

RE: first time array
In experimenting with a 2 dimensional array I used Pascal's coding example and have the below code now (which works and generates the correct output) but I don't understand the loop mechanics. For example: when I enter 8 cassettes in the form feeding this array, I get the following output, which is correct, but don't know why--... can someone breakdown how the cfloops below work? (for instance I thought this output would relect 8 records, not 1). I get totally lost with the 2nd loop ... then one loop is wrapped within another -- whoa! thanks in advance OUTPUT: Record 1 iss1,iss2,iss3,iss4,iss5,iss6,iss7,iss8 cass1,cass2,cass3,cass4,cass5,cass6,cass7,cass8 date1,date2,date3,date4,date5,date6,date7,date8 pub1 Record #i# #cassettes_Array[i][j]# [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]
Re: first time array
Frank, Yep, you're going down the right track - that'd pretty much copy elements out of someCollection into your books structure.

Haven't played with structure yet, so .. If you have a bunch of items (cassettes), it makes sense to store them in an array. If you have things that you want to associate with each cassette, that cassette should be described as a structure. So, it sounds like an array of structures is a good way to describe your data.

RE: first time array
You should use structures if you want to group info about something (like you are doing) because you have an alphanumerical index that can reflect the content. It makes writing code easier. In your example, you had to remember what 1,2,3 and 4 stands for. If you use a struct this is easier Example: Employee = ArrayNew(1); Employee[1] = "Pascal"; Employee[2] = "Peters"; Here you have to remember 1 stands for first name and 2 for last name Employee = StructNew(); Employee["firstname"] = "Pascal"; Employee.lastname = "Peters"; It is easier to know what employee.firstname means (and makes more readable code). I only use arrays if I need ordered data (that's what they are for). > -Original Message- > From: Tim Laureska [mailto:[EMAIL PROTECTED] > Sent: dinsdag 29 juni 2004 16:35 > To: CF-Talk > Subject: RE: first time array > > Tony... why are structures a better way to go than than arrays > > -Original Message- > From: Tony Weeg [mailto:[EMAIL PROTECTED] > Sent: Tuesday, June 29, 2004 10:08 AM > To: CF-Talk > Subject: RE: first time array > > tim, then there is this GREAT > thing called a structure, play with this one... > > > > > > > > > > > > > Hello world, my name is #me.myFirstName# > #me.myLastName# and i live in #me.myCity# > > > > -----Original Message- > From: Pascal Peters [mailto:[EMAIL PROTECTED] > Sent: Tuesday, June 29, 2004 10:06 AM > To: CF-Talk > Subject: RE: first time array > > A 2D array requires 2 indexes.

Because 2 is the number of dimensions in ArrayNew(2). If you want one dimension, you have to use ArrayNew(1).

RE: first time array
OK... so in the case I have... a form where a client enters cassette reference material into a form (each cassette has 4 attributes... issue no., cassette title, date and publication title) an array would appear to be better since there would be upwards of 25-30 cassettes entered at one time..no?

RE: first time array
agreed, 100% dave has such an eloquent way of explaining things... I just cant. I use arrays for dumb data, and structures for more intelligent data. I use arrays when I have to order things, add them up, or whatever... I use structures when I have multi-dimensional data that is easier to decipher. anyway, STUDY the heck outta these (Structs and Arrays) since the cfmx cert exam is laden heavily with their syntax etc... tw -Original Message- From: Dave Watts [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 29, 2004 10:52 AM To: CF-Talk Subject: RE: first time array > Tony... why are structures a better way to go than than arrays While I'm not Tony, I wouldn't say that structures are better than arrays or vice-versa.

RE: first time array
Thomas... I changed what I had to this: (but now getting the error below, which is a bit cryptic). Error Diagnostic Information An error occurred while evaluating the _expression_: cassettes_Array[1]=form.issue Error near line 11, column 22. Cannot set element of indexed object The element at position 1 of the object cannot be set. May be the object is read-only. The object has elements in positions 1 through 0. The error is in dimension 1 of object "cassettes_Array". -Original Message- From: Thomas Chiverton [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 29, 2004 9:42 AM To: CF-Talk Subject: Re: first time array On Tuesday 29 Jun 2004 14:42 pm, Tim Laureska wrote: > > > > > > cassettes_Array[ArrayLen(cassettes_Array)+1][4]=#form.publication#> That should be cfset cassettes_Array[1]=form.issue cfset cassettes_Array[2]=form.title cfset cassettes_Array[3]=form.date1 to match your cfloop. cfdump var="#cassettes_Array#" is useful for figuring out what you've just built when constructing nested structures. -- Tom Chiverton Advanced ColdFusion Programmer Tel: +44(0)1749 834997 email: [EMAIL PROTECTED] BlueFinger Limited Underwood Business Park Wookey Hole Road, WELLS.

Re: first time array
Hi Tim, I'm not sure why you're using a two-dimensional array here - also, this looks like a place where a structure could simplify your life greatly. Instead of having to remember "1 = issue, 2 = title, etc.," with a structure, you can just name things what they are. Maybe try something like this: #cassette_Structure.issue# #cassette_Structure.title# #cassette_Structure.date1# #cassette_Structure.publication# #i#: #cassette_Structure[i]# You can expand on this at will - if you need to keep track of multiple cassettes, you could create a cassette_Array where each element is, in turn, a cassette_Structure like the one created above. -Joe - Original Message - From: Tim Laureska <[EMAIL PROTECTED]> Date: Tue, 29 Jun 2004 09:42:21 -0400 Subject: first time array To: CF-Talk <[EMAIL PROTECTED]> This is the first time I've tried to use an array and I have a very basic question... how do you get the array contents to display !? this must be something silly I'm not doing I have one form template that sends 4 form field entries to a processing template.

This is the first time I've tried to use an array and I have a very basic question... how do you get the array contents to display !? this must be something silly I'm not doing I have one form template that sends 4 form field entries to a processing template.
