package actions {

 

    import flash.display.movieclip;

    import flash.events.*;

    import flash.net.*;

    import flash.text.*;

       

    public class main extends movieclip {

       

        public function main ():void {

           

            submit_button.buttonmode = true;

 

            submit_button.addeventlistener(mouseevent.mouse_down, checklogin);

           

            username.text = "";

            password.text = "";

       

        }

       

        public function checklogin (e:mouseevent):void {

            if (username.text == "" || password.text == "") {

               

                if (username.text == "") {

               

                username.text = "enter username";

               

                }

               

                if (password.text == "") {

               

                password.text = "enter password";

               

                }

           

            } else {

           

                processlogin();

           

            }

       

        }

       

        public function processlogin ():void {

                   

            var phpvars:urlvariables = new urlvariables();

           

            var phpfilerequest:urlrequest = new urlrequest("login.php");

           

            phpfilerequest.method = urlrequestmethod.post;

           

            phpfilerequest.data = phpvars;

           

            var phploader:urlloader = new urlloader();

            phploader.dataformat = urlloaderdataformat.variables;           

            phploader.addeventlistener(event.complete, showresult);

           

            phpvars.systemcall = "checklogin";

            phpvars.username = username.text;

            phpvars.password = password.text;

           

            phploader.load(phpfilerequest);

       

        }

       

        public function showresult (event:event):void {

                       

            result_text.autosize = textfieldautosize.left;

           

            result_text.text = "" + event.target.data.systemresult;

        }

    }

}

 

[php]

 

<?php

 

include_once "dbconnect.php";

 

$username = $_post['username']; //variables flash

$password = $_post['password'];

 

if ($_post['systemcall'] == "checklogin") {

    

$sql = "select * users username='$username' , password='$password'";

 

$query = mysql_query($sql);

 

$login_counter = mysql_num_rows($query);

 

if ($login_counter > 0) {

    

print "systemresult=welcome $username!";

 

} else {

 

print "systemresult=invalid user!";

 

}

}

?>

you want check value returns , use decide whether go next scene or not.

 

        public function showresult (event:event):void {

                       

            result_text.autosize = textfieldautosize.left;

           

            result_text.text = "" + event.target.data.systemresult;

 

            if(string(result_text.text).indexof("welcome") == 0) {

 

                   gotoandplay(1, "scenename");

            }

 

 

        }

 

what first line checks see if word welcome @ start of whatever in textfield (starts @ index 0).  if does, issues command move frame/scene
