error outputting html with javascript - php

Question

I have this php code, with which I am trying to generate a popup window that will contain the contents of a html file, however after adding in the script tags, no html is displayed. I tried echoing out $row2, but the word array is printed to the screen and nothing else.
<?php
session_start();
if (isset($_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>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);
?>
edit: I have fixed the errors that Roborg pointed out, however the script will still not load and does not give a precise error.
i have updated the code above

Answer 1

As well as the missing </script>,
child1.document.write('.$row2["ARTICLE_DESC"].')
should be
child1.document.write(' . json_encode($row2["ARTICLE_DESC"]) . ');
The json_encode() function will take care of any quoting for you.
Edit:
<a href='#' onclick=makewindows()> should be <a href='#' onclick='makewindows(); return false;'> - You should have quotes there, and the return false will stop you getting taken to "#" when you click the link.
Also, from memory I'm not sure you can open about:blank and then write to it - I think it sees that as cross-domain scripting. You might be better off creating a minimal "blank.html" file on your server and using that.

Answer 2

You have to print_r an array, like print_r($row2);

Answer 3

In this line:
$row2 = mysql_fetch_array($htmlset);
You are setting $row2 to be an array representing an entire row of the result from your query. Even if the "row" is just one field, it's still an array. If you want to get just the value of the first field, you can use mysql_result.
The parameters are: resource $result , int $row [, mixed $field ] so an example of the usage would be:
// 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);

Answer 4

Your <script> tag is never closed and your JavaScript instructions are not ended with semicolons. It might be the source of the problem.
