Part 3 - adding the code

OK here comes the fun part the code!!!

Actions on frame 1 of (actions layer)

loadVariablesNum ("http://localhost/pub_news.cfm", 0);

Here we load the data that the coldfusion page returns, we load the data into level 0 of the movie.(localhost is the address of the coldfusion server holding the cfm page)

Actions on frame 2

if (_root.go == "1") {
	gotoAndStop ("loaded");
} else {
	gotoAndStop ("headlines");
}

OK here we check that the data is fully loaded, if we continue without fully loaded data we will produce errors. This works by having the coldfusion page pass "go" as its last variable, therefore we can check that all other data is loaded and if it isn't loop until it is.

Actions on frame 3

ID_array = _root.N_IDs.split("|");
Title_array = _root.N_titles.split("|");
Dates_array = _root.N_dates.split("|");

h1 = title_array[0];
h2 = title_array[1];
h3 = title_array[2];
h4 = title_array[3];
h5 = title_array[4];

story1 = ID_array[0];
story2 = ID_array[1];
story3 = ID_array[2];
story4 = ID_array[3];
story5 = ID_array[4];

OK this is the core part of the code! Firstly the coldfusion page passes the data in this format :

&N_IDs=15|19|20|13|17&N_titles=Deposed Wahid leaves Jakarta palace|Alcatel to slash 14,000 jobs|Uproar as Turkey plans virginity tests|Macedonia rebels pull back|Croatian general to appear at tribunal&go=1

Flash separates this into its variables. e.g.. N_IDS=15|19|20|13|17

Each variable is separated by the & symbol, but the data after this is useless in its current format e.g.. 15|19|20|13|17. So what can we do with this?

OK the data is separated by the "|" symbol, so we use the split function to separate each value into an array.

Syntax

myString.split(delimiter);

Arguments delimiter

The character used to delimit the string. Description Method; splits a String object by breaking the string wherever the specified delimiter argument occurs, and returns the substrings in an array. If no delimiter is specified, the returned array contains only one element—the string itself. If the delimiter is an empty string, each character in the String object becomes an element in the array.

So when we split the data we put it into the variables ID_array etc.

Next we make our titles appear in the buttons by assigning the array elements to the h1,h2,h3,h4, and h5 dynamic text boxes.(Remember that arrays start a 0 not 1).

The next part of our code assigns the elements of the ID_array to the story1,2,3,4,5 variables. The IDs are for the next part when we query the database.

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
