Question

我是AS3的新手，我正在尝试在php中执行搜索类型文件（以提取与用户名匹配的信息）并将结果返回到AS3。 php将所有变量返回到AS3，除了第一个输入，当它第二次循环时，所有变量都通过ok。我也尝试进行多字段搜索并在AS3中返回具有类似原理的结果，但同样的问题正在发生。请帮我看看它是php错误还是AS3问题。谢谢你的时间

Autoresult.php

<?php
ini_set('display_errors', 1); error_reporting(E_ALL);

session_start();

include 'connect.php';



$username=$_SESSION['username'];


$result=mysqli_query($con,"SELECT * FROM Automatch WHERE username = '$username'")or die( mysqli_error($con));
$solutions = array();
while ($row = mysqli_fetch_assoc($result))
        {

          print "nobed=".$solutions[0]=$row['nobed'];
        print "&zip=".$solutions[1]=$row['zip'];
      print "&rangelow=".$solutions[2]=$row['rangelow'];
     print "&rangehigh=".$solutions[3]=$row['rangehigh'];
        }

        ?>

Answer 1

尝试类似的东西：

tf.text = books[k].nobed || '';
tf1.text = books[k].zip || '';
tf2.text = books[k].rangelow || '';
tf3.text = books[k].rangehigh || '';

或者这个：

tf.text = "";
if ( books[k].nobed !== null ) tf.text = books[k].nobed;
etc...

Answer 2

声明variabless = new URLVariables（）;

as

var variables：URLVariables = new URLVariables（）;

实例化varibles好友。
