How to get a result from a database to check if record exists?

Hello guys,

I'm trying to access a record from a table in the database to check if exists to select a checkBox.

Here are my codes so far.

This is the php code:

public function mpiIICheckIfExist($item) {

  $stmt = mysqli_prepare($this->connection,

  "SELECT mpiIIId

  FROM $this->wo2mpi2ii

  WHERE wo2mpiId = ? AND mpiIIId = ?

  LIMIT 1"

  );

  $this->throwExceptionOnError();

  mysqli_stmt_bind_param($stmt, 'ii', $item->wo2mpiId, $item->mpiIIId);

  $this->throwExceptionOnError();

  mysqli_stmt_execute($stmt);

  $this->throwExceptionOnError();

  $rows = array(); 

  mysqli_stmt_bind_result($stmt, $row->mpiIIId);

  while (mysqli_stmt_fetch($stmt)) {

       $rows[] = $row;

       $row = new stdClass();

       mysqli_stmt_bind_result($stmt, $row->mpiIIId);

     }

  mysqli_stmt_free_result($stmt);

     mysqli_close($this->connection);

     return $rows;

  }

When I test the code in Flash Builder like this {wo2mpiId:1, mpiIIId:1} I get wha I expect "mpiIIId = 1"

My problem is that I can access this variable the way I need to.

Here is my mxml file.

     protectedfunction getIItems(event:FlexEvent):void {

          getMpiII.token = mpiService.getMpiIndividualItems(mpiItemId);

          getMpiII.addEventListener(ResultEvent.RESULT, genItems);

      }

      protectedfunction genItems(event:ResultEvent):void {

          mpiVO.wo2mpiId = mpiId;

          for (var i:int = 0; i < getMpiII.lastResult.length; i++) {

          iBox = new spark.components.CheckBox();

          iBox.id = getMpiII.lastResult[i].id;

       // ***************** PROBLEM SECTION -- I Trying to do an if statement here but I can't get the return value to compare

          mpiVO.mpiIIId = int(iBox.id);

       //trace(mpiVO.wo2mpiId); // expected value - OK

       //trace(mpiVO.mpiIIId); // expected value - OK

          existMpiII.token = mpiService.mpiIICheckIfExist(mpiVO);

          trace(existMpiII.lastResult[0].mpiIIId);  // NOTHING HERE

       // ***************** END PROBLEM SECTION

          iBox.label = getMpiII.lastResult[i].individualItem;

       //iBox.addEventListener(MouseEvent.CLICK, checkboxHandler);

          iFormContent.addElement(iBox);

          }

      }

     <fx:Declarations>

       <s:CallResponder id="existMpiII" result="existMpiII.lastResult"/>

       <s:CallResponder id="getMpiII"/>

       <s:CallResponder id="createMpiII"/>

       <wampiservice:WampiService id="mpiService" showBusyCursor="true"/>

     </fx:Declarations>

Please help, if need more codes let me know.

Thank you, Robert
