标签: javascript php rss undefined elements

我在javascript中使用此代码显示rss:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>jQuery RSS Reader</title>

<link rel="stylesheet" type="text/css" href="style.css" />

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" ></script>
<script type="text/javascript" src="js/jquery.jfeed.pack.js"></script>
<script type="text/javascript" src="js/jquery.flips.min.js"></script>
<script type="text/javascript">
jQuery(function() {

jQuery.getFeed({

    url: 'last_20_reports.php',
    success: function(feed) {

        var html = '';

        for(var i = 0; i < feed.items.length && i < 20; i++) {

            var item = feed.items[i];

            html += "<div class='block'>"
            // Gets the RSS link and title
            + '<h3>' + item.title + '</h3>';

            html += item.description + '<br><br>';// Gets the RSS description


            html += "<div class='grey'>"
            // Gets the RSS pubDate
            + 'από ' + item.author +'<br>'
            + 'στις ' + item.updated
            + '</div>';               

            // Gets the RSS category
            //html += item.category
            html += '</div>';


        }
        jQuery('#latestnews').append(html);

        // Adds the jQuery Flips element. The direction can left, top or bottom/
        $('#news').flips( { autorun_delay:1000, direction: 'right'});
    }    
});
});
</script>
</head>

<body>

<div class="to-flips" id="news">        
    <h1>Πρόσφατες αναφορές</h1>        
    <div class="content">           
       <div id="latestnews"></div>            
    </div>
    <div class="flipnav"></div>
</div>

</body>
</html>

显示每个项目的元素标题和描述,但作者和类别显示为未定义。你能帮助我吗?

xml''file''(last_20_reports.php)是:

<?php
header ("Content-Type: application/xml;");


$db_host = "***";
$db_username = "***";
$db_pass = "***";
$db_name = "dhmos_patras_db";

$con = mysql_connect("$db_host","$db_username","$db_pass") or die ("Could not connect to mysql");
$sel = mysql_select_db("$db_name") or die ("No database");  


$sql = "SELECT * FROM reports INNER JOIN categories ON reports.categoryID = categories.categoryID INNER JOIN members ON reports.userID = members.memberID ORDER BY submit_date DESC LIMIT 0, 20"; 
$result = mysql_query ($sql,$con);

//xml 
echo  '<?xml version="1.0" encoding="UTF-8" ?> 
<rss version="2.0">
<feed xmlns="http://www.w3.org/2005/Atom">';

echo '<channel> ';

while($row = mysql_fetch_array($result)) 
{
    echo '<item>';
    echo    '<title>'.$row['title'].'</title>';  
    echo    '<description>'.$row['description'].'</description>';
    echo    '<pubDate>'.$row['submit_date'].'</pubDate>';
    echo    '<category>'. $row['category_name'] .'</category>';
    echo    '<author>'. $row['username'] .'</author>';
    echo '</item>';
}

echo '</channel>';
echo '</feed>';
echo '</rss>';

?>

提前致谢并抱歉我的英语!
