我知道我正在尝试做什么，而且我知道代码可以正常工作，但我的网站无法显示。
如果其他人可以看一遍，因为我确实在寻找一个半小时的实力。
如果你们可以浏览它，那就太棒了。
代码：
<?php include('includes/pageNav.php');
include('config.php');
$sql = "SELECT * FROM sponsoredBackground ORDER BY id DESC";
$retval = mysql_query( $sql, $con );
if(! $retval )
{
die('Could not get data: ' . mysql_error());
}
echo "<div id=\"headerSlider\">";
while($row = mysql_fetch_array($retval, MYSQL_ASSOC))
{
echo "<div class=\"headerContainer\" style=\"background: transparent url('/images/".$row['imageName']."') 0 0 no-repeat;\">";
echo "<div class=\"headerLeftContent\">";
echo "<div class=\"sponsoredBackground\">";
echo "<a href=\"".$row['imageName']."\">";

苦苦寻找故障的位置，明确地说是愚蠢的。提前谢谢。
