RE: array - structure question

2002-01-11 Thread Raymond Camden


Others have sent in suggestions, but I'd like to show another way of
doing it as well... with UDFs! I have an article coming out for CFDJ
that discusses this concept, but the idea is simple. You can use a UDF
to quickly create structures and, if you know what you are doing, safely
append to the local scope. Watch:

Original:

 // DEPARTMENT 1
 item.department = 'Department 1;
 item.name = 'Bill Jones;
 item.email = '[EMAIL PROTECTED];
 
 additem = arrayAppend(request.contact, item);
 
 // DEPARTMENT 2
 item.department = 'Department 2;
 item.name = 'Joe Jones;
 item.email = '[EMAIL PROTECTED];

With UDFs:

request.contact = arrayNew();
addContact(Department 1,Bill Jones,[EMAIL PROTECTED]);
addContact(Department 2,Jpe Jones,[EMAIL PROTECTED]);
etc...


function addContact(dpt,name,email) {
var d = structNew();
d.dpt = dpt;
d.name = name;
d.email = email;
arrayAppend(request.contact,d);
}

 Subject: array - structure question
 
 
 On my Application.cfm page, I want to use an array to 
 populate a feedback
 form with contacts, and the response page with the 
 corresponding e-mail
 addresses in the to attribute.
 
 This seemed more practical than storing the info in a database, for an
 amount of data this limited, but still give some flexibility 
 for making
 changes down the road.
 
 So here's a snip from within my CFScript:
 
 
 // department mail addresses
 // e-mail addresses and contact information dropped into an 
 array of structs
 to facilitate retrieval and updating
 
 request.contact = arrayNew(1);
 item = structNew();
 
 
 // DEPARTMENT 1
 item.department = 'Department 1;
 item.name = 'Bill Jones;
 item.email = '[EMAIL PROTECTED];
 
 additem = arrayAppend(request.contact, item);
 
 // DEPARTMENT 2
 item.department = 'Department 2;
 item.name = 'Joe Jones;
 item.email = '[EMAIL PROTECTED];
 
 additem = arrayAppend(request.contact, item);
 
   and so on.
 
 The problem is, the last entry keeps overwriting the 
 structures at each
 array position.  In other words, request.contact[1] contains 
 the data for
 array position 10, and position 2 contains the data for 10 
 ... and so on.
 
 Should position 1 of the array remember what it had initially 
 and not get
 over written by the time the 2 position is created, and so on?
 
 How can I get each position in the array to have structures 
 with discrete
 and unique information?

RE: array - structure question

2002-01-10 Thread Brendan Avery


Structs are like Pointers/Linked-Lists and reference-based 
data-structures
in other programming languages.  If you don't know what I'm talking 
abooot,
thats okay.  Just remember this simple example:

cfset x=StructNew()
cfset y=x

y is now x and x is now y for all intents and purposes.  any 
modifications
to y are made to x and visa versa.  you have 2 options.

option #1: Use StructCopy to copy Item to that array element
option #2: Set Item=StructNew after assigning the value.  Example:

// department mail addresses
// e-mail addresses and contact information dropped into an array of 
structs
to facilitate retrieval and updating

request.contact = arrayNew(1);

// DEPARTMENT 1
item = structNew();
item.department = 'Department 1;
item.name = 'Bill Jones;
item.email = '[EMAIL PROTECTED];

additem = arrayAppend(request.contact, item);

// DEPARTMENT 2
item=StructNew();
item.department = 'Department 2;
item.name = 'Joe Jones;
item.email = '[EMAIL PROTECTED];

additem = arrayAppend(request.contact, item);

2002-01-10 Thread Birgit Pauli-Haack


this may be looking a little awkard but it works...

try

item1 = structNew();
item1.department = 'Department 1;
item1.name = 'Bill Jones;
item1.email = '[EMAIL PROTECTED];
additem = arrayAppend(request.contact, item1);


item2 = StructNew();
item2.department = 'Department 2;
item2.name = 'Joe Jones;
item2.email = '[EMAIL PROTECTED];
additem = arrayAppend(request.contact, item2);

cheerio
