我是php和AS3的新手，尝试搜索php并将循环数组解析为AS3。但不太确定如何，因为我将每个部分与＆amp ;.分开。但是当它被环回时数组的结尾，没有＆amp;附加，所以整个数组是第一项合并到最后。并且第一项返回null。
我尝试将event.target.data跟踪到动态文本字段中，第一个项目返回null，并合并到最后一个项目中。
的search.php
<?php
ini_set('display_errors', 1); error_reporting(E_ALL);
session_start();
include 'connect.php';
if($_POST)
{
$nobed = ($_POST['nobed']);
$Location = ($_POST['Location']);
$zip = ($_POST['zip']);
$price = ($_POST['price']);
$sql = array();
if (!empty($nobed)) {
$sql[] = "nobed='$nobed'";
}
if (!empty($Location)) {
$sql[] = "Location='$Location'";
}
if (!empty($zip)) {
$sql[] = "zip='$zip'";
}
if (!empty($price)) {
$sql[] = "price='$price'";
}
$sql = implode(' AND ', $sql);
$sql = "SELECT * FROM Listing" . (!empty($sql)? " WHERE " . $sql: '');
$result = mysqli_query($con,$sql);
$solutions = array();
while ($row = mysqli_fetch_assoc($result))
{
echo "nobed=".$solutions[1]=$row['nobed'],"&zip=".$solutions[2]=$row['zip'],"&Location=".$solutions[3]=$row['Location'],"&price=".$solutions[4]=$row['price'];
}
}
?>
因为“nobed =”没有＆amp;，所以最后一项PRICE不会以＆amp; ，因此循环无法正确分离和显示。而且当我试图添加一个＆amp;，在nobed之前它也显示错误。它在webbrowswer中没有任何问题。
示例结果（粗体部分是发生循环问题的地方）
nobed = 3及压缩= 19104＆安培;位置= TestListing＆安培;价格= 750nobed = testing3＆安培;拉链= testing3＆安培;位置= testing3＆安培;价格= testing3
当我尝试回复第一部分时，在动态文本中对其进行回复，并说Error #2007: Parameter text must be non-null.因为我不能放一个＆amp;在nobed之前，结果nobed合并到Location，所以nobed变为Null。
当我尝试将event.target.data设置为带有＆amp;的动态文本字段时在面前被称为“＆amp; nobed =”然后我有Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.
任何想法我应该如何解决它？谢谢你的时间。希望我的问题不是太新手。
AS3代码
function Asandler(event:Event):void{
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 )
{
// trace key => value
trace( nobed, resultObject[s] );
trace( Location, resultObject[s] );
}
}
Php
$nobed1 = array();
$zip1= array();
$Location1 = array();
$price1 = array ();
// create all you want
while( $row = mysqli_fetch_assoc($result) !== false )
{
// add result row to your output's next index
$nobed1[] = $row['nobed'];
$zip1[] = $row['zip'];
$Location1 = $row ['Location'];
$price1 = $row ['price'];
//...
}
// echo the json encoded object
echo json_encode( array('nobed'=>$nobed1, 'zip'=>$zip1,'Location'=>$Location1,'price'=>$price1 ) );
}
当我点击AS3中的搜索按钮并启动事件ASandler时，它会立即喊出错误，输出窗口中没有任何内容。

也许最好使用数组来存储结果并将数组编码为json并在as3中解析它。
例如：
$result = mysqli_query($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 );
在您的AS3代码中，您可以从json字符串中获取对象，如下所示：
// retrieve data from php call
var resultString:String = yourLoader.data;
// parse result string as json object
var resultObject:Object = JSON.parse( resultString );
在这种情况下，您的resultObject应该是一个包含所有行的数组。
// retrieve data from php call
var resultString :String = yourLoader.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;
// loop the result array
for( var i:int = 0; i<len; ++i )
{
// trace nobed value
trace( resultArray[i].nobed );
}

如果要为每个阵列部件命名，可以执行以下操作：
PHP：
$result = mysqli_query($con,$sql);
// create your outputs array
$nobed = array();
$zip = array();
$Location1 = array();
$price1 = array();
// create all you want
// fetch your results
while( $row = mysqli_fetch_assoc($result) !== false )
{
// add result row to your output's next index
$nobed[] = $row['nobed'];
$zip[] = $row['zip'];
$Location1[] = $row ['Location']; // you forgot the [] here meaning add to the end of the array
$price1[] = $row ['price']; // you forgot the [] here meaning add to the end of the array
//...
}
// echo the json encoded object
echo json_encode( array('nobed'=>$nobed, 'zip'=>$zip, 'Location'=>$Location1, 'price'=>$price1) );
AS3：
function Asandler(event:Event):void
{
// trace your recived data so you can see it before any parsing error
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 )
{
// you cannot do this as nobed and Location object don't exists i think, you can trace string or properties maybe trace( 'nobed', resultObject[s] ) but as s is not nobed all the time it's not correct
//trace( nobed, resultObject[s] );
//trace( Location, resultObject[s] );
// so maybe add a switch case to make specific operation in function of the key
// with switch case you can make a specific code block for a specific value of the variable passed in the switch
switch(s)
{
// if( s == 'nobed' )
case 'nobed'
trace( 'nobed', resultObject[s] );
// do what you want with your nobed array
break;
// if( s == 'zip' )
case 'zip'
trace( 'zip', resultObject[s] );
// do what you want with your zip array
break;
// if( s == 'Location' )
case 'Location'
trace( 'Location', resultObject[s] );
// do what you want with your Location array
break;
// if( s == 'price' )
case 'price'
trace( 'price', resultObject[s] );
// do what you want with your price array
break;
}
}
}
尝试使用这样的简单php脚本：
<?php
$row = array();
for( $i=0; $i<10; $i++ )
{
$row[] = array('nobed'=>'nobed'.$i, 'zip'=>$i, 'Location'=>$i, 'price'=>$i);
}
// create your output array
$nobed1 = array();
$zip1 = array();
$Location1 = array();
$price1 = array();
// fetch your results
for( $i=0; $i<10; $i++ )
{
// add result to your output next index
$nobed[] = $row[$i]['nobed'];
$zip[] = $row[$i]['zip'];
$Location1[] = $row ['Location']; // you forgot the [] here meaning add to the end of the array
$price1[] = $row ['price']; // you forgot the [] here meaning add to the end of the array
}
echo json_encode( array('nobed'=>$nobed, 'zip'=>$zip,'Location'=>$Location1,'price'=>$price1) );
?>
