I have been developing a flash trivia using some tutorial. Everything went fine & I have added some new features to the trivia. The tutorial provides you with a url link to their database in order for you to test your trivia. They used ASP.NET as a way to load & display questions from their DB. Now I should create my own trivia questions & answers and store them in my own DB. The tutorial teaches you how to develop the flash trivia but they didn't mention how to make the ASP.NET file to link the DB to the flash trivia. As I never used ASP.NET before, I thought I would use PHP & MySQL instead. I created my own DB, inserted some random questions & answers and wrote the php code. When I try to test the flash trivia using my DB & the php file I have wrote, it doesn't seem to work. The flash trivia file is working normally but the questions & answers are not loaded from the MySQL DB.

I have included below the ActionScript I use (Working Fine) Plus PHP file (doesn't seem to be working) & screen shots of the MySQL DB.

ActionScript -Frame 1-

//Stop the timeline
stop();

//Determine the number of questions in the database
var numQCount:Number;
//Create trivia data receiver objects
var varTriviaCount:LoadVars = new LoadVars();
//Load the data from the external web application
varTriviaCount.load("http://localhost/FlashDB/gettriviaquestioncount.php");

//Once the data loads from remote server, get the count
varTriviaCount.onLoad = function(blnSuccess:Boolean):Void {
//See if data was loaded
if(blnSuccess){
//Parse the data returned
numQCount = varTriviaCount.qCount;
} else {
//Display an error
trace("Error occurred on LoadVars");
}
};

//When the Faceoff button is clicked, go to the trivia game
btnLaunch.onRelease = function():Void {
gotoAndStop(10);
};

ActionScript -Frame 10-

//Initialize trivia variables

PHP Files
1. DB.php

<?php 
$host = 'localhost'; 
$user = 'username';
$pass = 'password';
$database = 'databasename';
?>

2.

<?php 


include("DB.php"); 

$table = 'tblTriviaAnswer';

mysql_connect ($host, $user, $pass); 
mysql_select_db ($database);

$result = mysql_query ( "SELECT * FROM `tbltriviaanswer`"); 
$newresult = mysql_query ("SELECT * FROM `tbltriviaquestion`");	



$i = 1; 

	while ( $i <= 10){

		$row = mysql_fetch_array($result); 
		 
		extract($row); 
		echo "$answerText";
		echo "$correctAnswer";
		$i = $i + 1; 
	}

$j = 1; 

	while ( $j <= 10){

		$row = mysql_fetch_array($newresult); 
		 
		extract($row);
		echo "$questionNum";
		$j = $j + 1;

	}
?>

MySQL DB ScreenShots





One Last thing is the DB ScreenShot that was included with the tutorial:



Do you have any ideas how can I edit the PHP file in order for the trivia to load the questions & answers ?

[the_3rock]

Some issues I've once experienced with loading data (sound actually) was that having the event-listener AFTER I call the load() function can actually be problematic. Would be best to have it defined BEFORE your load() execution. I don't garantee that it will fix your problem though! Just something maybe to try.

[the_3rock]

Also, the method you're using to pass the data from Flash to your PHP script is "GET". That's fine, but it seems you're not using it at all in your PHP script! You can obtain your passed variables... say... questionNum - by using $_GET["questionNum"].

To test your script as standalone (to isolate any problems in your script first), you can open your browser to that page http://localhost/FlashDB/gettriviaquestion.php and pass the questionNum in the URL as well: http://localhost/FlashDB/gettriviaqu...?questionNum=1. That's the beauty of the GET method, easy to test. If you would of chosen POST, then it would of been a little trickier!

Hope this helps!

hi, recently i have been searching some nice way to communicate with server and here you can find some working example: http://www.viztoolkit.com/2009/03/ho...ate-with-flash
