How to assign/parse JSON data from 1 as file to another? - actionscript-3

Question

and trying to create this search form with a few fields and a search button,when search button is clicked, it goes to next page to display the results and place the results into boxes. E.g. Result 1 has(name,Location,zip), result 2(name,Location,zip) etc
What i need is, php to search and echo the data in JSON, and AS3 VO to receive the data in JSON, Split the data and parse the data to the Vector file and then put them into boxes.
I believe i am just missing 1 final step, i can get the JSON into AS3, i can trace the data. But i can't get it from the first AS(searchVO) file into the Vector AS(SEarchVector) file.
Please give me some opinion thanks.
AS3 VO(receiving the JSON)
function Asandler(event:Event):void{
trace( event.target.data );
var resultString :String = event.target.data;
// parse result string as json object
var resultObject :Object = JSON.parse( resultString );
// loop all keys in the object
for( var s:String in resultObject )
{
switch(s)
{
case 'nobed'
:'nobed', resultObject[s] ;
break;
case 'zip'
:zip=( 'zip', resultObject[s] );
break;
case 'Location'
:Location=( 'Location', resultObject[s] );
break;
case 'price'
:price=( 'price', resultObject[s] );
break;
}}}
SearchVector
public class SearchVectorTest extends MovieClip
{
public function SearchVectorTest()
{
super();
// This part is the parser, i assume i just have to fix this part and the JSON data will come through, but not sure how
var test:Vector.<searchVO1> = new Vector.<searchVO1>();
for (var i:int = 0; i < 10; i++)
{
var tests:searchVO1 = new searchVO1();
tests.nobed = nobed ;
tests.zip = zip;
tests.Location = Location[i];
tests.price = price[i];
test.push(tests);
}
// using that we can loop through every book in the entry
for (var j:int = 0; j < test.length; j++)
{
trace(test[j].nobed);
trace(test[j].zip);
trace(test[j].Location);
trace(test[j].price);
test[j].nobed;
test[j].zip;
test[j].Location;
test[j].price;
}
// loop and put the text into boxes
var currentY:int = 270;
for (var k:int = 0; k < test.length; k++)
{
var Bolder:Listing5 = new Listing5();
Bolder.x=80;
var bf:TextField = new TextField();
var bf1:TextField = new TextField();
var bf2:TextField = new TextField();
var bf3:TextField = new TextField();
bf3.width = 100;
bf.defaultTextFormat = new TextFormat("Arial", 12, 0, null, null, null, null, null, TextFormatAlign.CENTER);
bf.width = 100;
bf.autoSize = TextFieldAutoSize.CENTER;
bf1.width = 100;
bf1.autoSize = TextFieldAutoSize.CENTER;
bf2.autoSize = TextFieldAutoSize.CENTER;
bf3.autoSize = TextFieldAutoSize.CENTER;
bf3.width = 100;
bf1.y= bf.height+5;
// Pulling the textfields content out from the current bookVO
bf.text = test[k].nobed;
bf1.text = test[k].zip;
bf2.text = test[k].Location;
bf3.text = test[k].price;
bf1.x = (Bolder.height-bf.height)*.5
bf3.x = (Bolder.height-bf.height)*.5
bf.x = (Bolder.height-bf.height)*.5
bf.y = (Bolder.height-bf.height)*.15
Bolder.addChild(bf);
Bolder.addChild(bf1);
Bolder.addChild(bf2);
Bolder.addChild(bf3);
// position the object based on the accumulating variable.
Bolder.y = currentY;
//visualAssetForBook.y = (visualAssetForBook.height+15)*k;
addChild(Bolder);
currentY += Bolder.height + 35;
}
}
}
}
Just tried it and it has 2 error,
On this line
searchVOs[i] = new searchVO1(resultArray[i].nobed, resultArray[i].zip, resultArray[i].Location, resultArray[i].price ); in the searchVO file.
Error says Incorrect number of arguments. Expect no more than 0.
And 1 line below that, createBoxes(searchVOs); it has an error,
Call to a possibly undefined method createBoxes.

Answer 1

If you wanted to pass it as VO it's better to use the following solution:
PHP:
$result = mysqli_query($con,$sql);
// create your output array
$output = array();
// fetch your results
while( $row = mysqli_fetch_assoc($result) !== false )
{
// add result row to your output's next index
$output[] = $row;
}
// echo the json encoded object
echo json_encode( $output );
and now you can retrieve your result directly as follow:
SearchVO.as:
package
{
public class SearchVO
{
public var nobed :String;
public var zip :String;
public var location :String;
public var price :Number;
public function SearchVO( nobed:String, zip:String, location:String, price:Number )
{
this.nobed = nobed;
this.zip = zip;
this.location = location;
this.price = price;
}
}
}
ASHandler function:
// retrieve data from php call
var resultString :String = event.target.data;
// parse result string as json object and cast it to array
var resultArray :Array = JSON.parse( resultString ) as Array;
// get the length of the result set
var len:int = resultArray.length;
// create vector of SearchVO
var searchVOs:Vector.<SearchVO> = new Vector.<SearchVO>();
// loop the result array
for( var i:int = 0; i<len; ++i )
{
searchVOs[i] = new SearchVO(resultArray[i].nobed, resultArray[i].zip, resultArray[i].Location, resultArray[i].price );
}
// call a function to create your boxes
createBoxes(searchVOs);
// or maybe create your SearchVector class and pass it your search vector
var mySearchVector:SearchVector = new SearchVector(searchVOs);
createBoxes function:
private function createBoxes( test:vector.<SearchVO> ):void
{
// loop and put the text into boxes
var currentY:int = 270;
for( var k:int = 0; k < test.length; k++ )
{
var Bolder:Listing5 = new Listing5();
Bolder.x=80;
var bf:TextField = new TextField();
var bf1:TextField = new TextField();
var bf2:TextField = new TextField();
var bf3:TextField = new TextField();
bf3.width = 100;
bf.defaultTextFormat = new TextFormat("Arial", 12, 0, null, null, null, null, null, TextFormatAlign.CENTER);
bf.width = 100;
bf.autoSize = TextFieldAutoSize.CENTER;
bf1.width = 100;
bf1.autoSize = TextFieldAutoSize.CENTER;
bf2.autoSize = TextFieldAutoSize.CENTER;
bf3.autoSize = TextFieldAutoSize.CENTER;
bf3.width = 100;
bf1.y= bf.height+5;
// Pulling the textfields content out from the current bookVO
bf.text = test[k].nobed;
bf1.text = test[k].zip;
bf2.text = test[k].Location;
bf3.text = test[k].price;
bf1.x = (Bolder.height-bf.height)*.5
bf3.x = (Bolder.height-bf.height)*.5
bf.x = (Bolder.height-bf.height)*.5
bf.y = (Bolder.height-bf.height)*.15
Bolder.addChild(bf);
Bolder.addChild(bf1);
Bolder.addChild(bf2);
Bolder.addChild(bf3);
// position the object based on the accumulating variable.
Bolder.y = currentY;
//visualAssetForBook.y = (visualAssetForBook.height+15)*k;
addChild(Bolder);
currentY += Bolder.height + 35;
}
}
or SearchVector Class:
public class SearchVectorTest extends MovieClip
{
public function SearchVectorTest(test:Vector.<SearchVO>)
{
super();
// This part is the parser, i assume i just have to fix this part and the JSON data will come through, but not sure how
// REMOVE THAT !
/*
var test:Vector.<searchVO1> = new Vector.<searchVO1>();
for (var i:int = 0; i < 10; i++)
{
var tests:searchVO1 = new searchVO1();
tests.nobed = nobed ;
tests.zip = zip;
tests.Location = Location[i];
tests.price = price[i];
test.push(tests);
}
*/
// using that we can loop through every book in the entry
for (var j:int = 0; j < test.length; j++)
{
trace(test[j].nobed);
trace(test[j].zip);
trace(test[j].Location);
trace(test[j].price);
// trace if you want but calling variable just for fun is not usefull
/*
test[j].nobed;
test[j].zip;
test[j].Location;
test[j].price;
*/
}
// loop and put the text into boxes
var currentY:int = 270;
for (var k:int = 0; k < test.length; k++)
{
var Bolder:Listing5 = new Listing5();
Bolder.x=80;
var bf:TextField = new TextField();
var bf1:TextField = new TextField();
var bf2:TextField = new TextField();
var bf3:TextField = new TextField();
bf3.width = 100;
bf.defaultTextFormat = new TextFormat("Arial", 12, 0, null, null, null, null, null, TextFormatAlign.CENTER);
bf.width = 100;
bf.autoSize = TextFieldAutoSize.CENTER;
bf1.width = 100;
bf1.autoSize = TextFieldAutoSize.CENTER;
bf2.autoSize = TextFieldAutoSize.CENTER;
bf3.autoSize = TextFieldAutoSize.CENTER;
bf3.width = 100;
bf1.y= bf.height+5;
// Pulling the textfields content out from the current bookVO
bf.text = test[k].nobed;
bf1.text = test[k].zip;
bf2.text = test[k].Location;
bf3.text = test[k].price;
bf1.x = (Bolder.height-bf.height)*.5
bf3.x = (Bolder.height-bf.height)*.5
bf.x = (Bolder.height-bf.height)*.5
bf.y = (Bolder.height-bf.height)*.15
Bolder.addChild(bf);
Bolder.addChild(bf1);
Bolder.addChild(bf2);
Bolder.addChild(bf3);
// position the object based on the accumulating variable.
Bolder.y = currentY;
//visualAssetForBook.y = (visualAssetForBook.height+15)*k;
addChild(Bolder);
currentY += Bolder.height + 35;
}
}
}
In all solutions you have to pass the array (or vector) to a function, you cannot retrieve it from nowhere like you do in this part of code:
for (var i:int = 0; i < 10; i++)
{
var tests:searchVO1 = new searchVO1();
tests.nobed = nobed ; // nobed don't exists here
tests.zip = zip; // zip don't exists here
tests.Location = Location[i]; // Location don't exists here and so Location[i]
tests.price = price[i]; // pricedon't exists here and so price[i]
test.push(tests);
}
I hope this could help you
PS: try use capital letters on begin of word only for class names and use lowercase start letters for variables. It's more clear for everyone ;) (ex: MyClassName, myVarName)
