Question

我有这个PHP代码，我试图生成一个包含html文件内容的弹出窗口，但是在添加脚本标签后，没有显示html。我尝试回显$ row2，但是字数组被打印到屏幕上，没有别的。

<?php
session_start();
if (isset($_GET["cmd"]))
  $cmd = $_GET["cmd"];
else
  die("You should have a 'cmd' parameter in your URL");
 $pk = $_GET["pk"];
$con = mysql_connect("localhost","root","geheim");
if(!$con)
{
die('Connection failed because of' .mysql_error());
}
mysql_select_db("ebay",$con);
if($cmd=="GetAuctionData")
{
$sql="SELECT * FROM Auctions WHERE ARTICLE_NO ='$pk'";
$sql2="SELECT ARTICLE_DESC FROM Auctions WHERE ARTICLE_NO ='$pk'";
$htmlset = mysql_query($sql2);
$row2 = mysql_fetch_array($htmlset);
echo $row2;
echo '<script> 
function makewindows(){
child1 = window.open ("about:blank");
child1.document.write('.$row2["ARTICLE_DESC"].');
child1.document.close(); 
}
</script>';

$result = mysql_query($sql);
while ($row = mysql_fetch_array($result))
{
echo "<div id='leftlayer'>
    <strong>Article Number</strong> ".$row['ARTICLE_NO']."
    <p><strong>Article Name</strong></p> ".$row['ARTICLE_NAME']."
    <p><strong>Subtitle</strong></p> ".$row['SUBTITLE']."
    <p><strong>Username</strong></p> ".$row['USERNAME']."
    <p><strong>Total Selling</strong></p> ".$row['QUANT_TOTAL']."
    <p><strong>Total Sold</strong></p> ".$row['QUANT_SOLD']."
    <p><strong>Category</strong></p> ".$row['CATEGORY']."
    <p><strong>Highest Bidder</strong></p> ".$row['BEST_BIDDER_ID']."
  </div>
<div class='leftlayer2'>
  <strong>Current Bid</strong> ".$row['CURRENT_BID']."
  <p><strong>Start Price</strong></p> ".$row['START_PRICE']."
  <p><strong>Buyitnow Price</strong></p> ".$row['BUYITNOW_PRICE']."
  <p><strong>Bid Count</strong></p> ".$row['BID_COUNT']."
  <p><strong>Start Date</strong></p> ".$row['ACCESSSTARTS']."
  <p><strong>End Date</strong></p> ".$row['ACCESSENDS']."
  <p><strong>Original End</strong></p> ".$row['ACCESSORIGIN_END']."
  <p><strong>Auction Type</strong></p> ".$row['AUCTION_TYPE']."
</div>
<div class='leftlayer2'>
    <strong>Private Auction</strong></p> ".$row['PRIVATE_AUCTION']."
  <p><strong>Paypal Accepted</strong></p> ".$row['PAYPAL_ACCEPT']."
  <p><strong>Auction Watched</strong></p> ".$row['WATCH']."

  <p><strong>Country</strong></p> ".$row['COUNTRYCODE']."
  <p><strong>Location</strong></p> ".$row['LOCATION']."
  <p><strong>Conditions</strong></p> ".$row['CONDITIONS']."
</div>
<div class='leftlayer2'>
  <strong>Auction Revised</strong></p> ".$row['REVISED']."
  <p><strong>Cancelled</strong></p> ".$row['PRE_TERMINATED']."
  <p><strong>Shipping to</strong></p> ".$row['SHIPPING_TO']."
  <p><strong>Fee Insertion</strong></p> ".$row['FEE_INSERTION']."
  <p><strong>Fee Final</strong></p> ".$row['FEE_FINAL']."
  <p><strong>Fee Listing</strong></p> ".$row['FEE_LISTING']."
  <p><a href='#' onclick='makewindows(); return false;'>Click for full description </a></p>
</div>";

$lastImg = $row['PIC_URL'];
echo "<div id='rightlayer'>Picture Picture
<img src=".$lastImg.">
</div>";

}

}
mysql_close($con);
?>

编辑：我修复了Roborg指出的错误，但是脚本仍然无法加载，也没有给出精确的错误。

我已更新上面的代码

Answer 1

缺少</script>，

child1.document.write('.$row2["ARTICLE_DESC"].') 应该是

child1.document.write(' . json_encode($row2["ARTICLE_DESC"]) . ');

json_encode()功能会为您处理任何报价。

编辑：

<a href='#' onclick=makewindows()>应该是<a href='#' onclick='makewindows(); return false;'> - 你应该在那里有引号，当你点击链接时return false将停止你被带到“＃”。

另外，从内存中我不确定你可以打开：空白然后写入它 - 我认为它看作是跨域脚本。您可能最好在服务器上创建一个最小的“blank.html”文件并使用它。

Answer 2

您的<script＆gt;标签永远不会关闭，您的javascript说明不会以分号结束。它可能是问题的根源

Answer 3

你必须print_r一个数组，如print_r($row2);

Answer 4

在这一行：

$row2 = mysql_fetch_array($htmlset);

您将$row2设置为表示查询结果的整行的数组。即使“行”只是一个字段，它仍然是一个数组。如果您只想获得第一个字段的值，可以使用mysql_result。

参数是：resource $result , int $row [, mixed $field ]所以使用的示例是：

// get the first field of the first row
$fieldVal = mysql_result($htmlset, 0);

// get the third field
$fieldVal = mysql_result($htmlset, 0, 2);

// get the first field of the 2nd row
$fieldVal = mysql_result($htmlset, 1);

使用javascript输出html时出错
