Question

first time posting, hopefully this will be helpful to others too. I’ve found a few posts on this topic but it appears I’m having quite a specific problem.

This is my output in PHP

questions=The ‘Sea Swallow’ is an alternative name for which bird?/In which sport would you see a ‘Western Roll’?/Who is better known as ‘Herbert Khaury’?/’Diet’ is the parliament of which country?/What is the real first name of Coco Chanel?/’The Aztecs’ were natives of which country?/What was invented by‘O.A. North’ in 1869?/King Zog was the ruler of which country?&answers=Seagull/Penguin/Tern/Cormorant&correct=0/0/1/0&

And this is my AS3 code

     var         request:URLRequest = new             
URLRequest("http://localhost:8888/Quiz/questions.php");
            request.method = URLRequestMethod.GET;

            var loader2:URLLoader = new URLLoader();
            loader2.addEventListener(Event.COMPLETE, completeHandler);
            loader2.dataFormat = URLLoaderDataFormat.TEXT;
            loader2.load(request);


            function completeHandler(event:Event) :void{

            var questions1 = event.target.data.questions1;

            // dynamic text box called username

            questionbox.question.text=event.target.data.questionbox.question.text;

            }

            var questions:String;
            var questionsArray:Array=questions.split("/");

I’m trying to get the question to appear in a dynamic text box,but am receiving the error code #2007 Parameter text must be non-null.

I’m effectively trying to turn my string into an array.

Can anybody see the problem here?

Any help would be greatly appreciated! Thanks in advance

EDIT:

This is my PHP code

<?php
//functions

function get_id($column, $table)
{
 $sql    = mysql_query("select $column FROM $table") ;
 while ($row    =mysql_fetch_array($sql))
 {
  return $row["ID"];
 }
}

function getquestions($id)
{
 $sql    =mysql_query("select text FROM questions WHERE quiz_ID =$id ");
 $questions   = array();
 while($row   = mysql_fetch_row($sql))
 {
  $questions[] = $row[0];
 }
 return $questions;
}

function getanswers($id)
{
 $sql    = mysql_query("select answer FROM answers WHERE question_ID= $id ");
 $answers = array();
 while($row    =mysql_fetch_row($sql))
 {

  $answers[] = $row[0]; 
 }

 return $answers;
}

function getcorrect($id)
{
 $sql    = mysql_query("SELECT correct FROM answers WHERE question_ID= $id ");
 $correct   =array();
 while($row    =mysql_fetch_assoc($sql))
 {
  $correct[]    =$row["correct"]; 
 }
   return $correct;
}


//Connect to Database
$con = mysql_connect("localhost","dinita","3nd3m0luk");

if(!$con)
{
 die('Could not connect: '.mysql_error());
}

else
{

 // SELECT DATABASE
mysql_select_db("quizCreation", $con);

// Create an array of data from database


$quizid    = get_id("ID","quizName");
$questionid    = get_id("ID", "questions");
$ques   = implode("/",getquestions($quizid));
$ans    =implode("/",getanswers($questionid)); 
$cor    =implode("/", getcorrect($questionid));


echo htmlentities( "questions"."=". $ques."&");
echo htmlentities("answers"."=".$ans."&");
echo htmlentities("correct"."=".$cor."&");

}

mysql_close($con); 

?>

If that is the output of your php code, then if you have to visualize it in the textield, you should change it like this:

        var questions:String = event.target.data.questions;
        questionbox.question.text=questions;

And if you want to convert the String as an Array, then do like this:

       var questionsArray:Array=questions.split("/");
