PHP mysql not showing up admin panel feature - php

Question

so i've been up for a long time working on this. So basically want I need to do is make an add, update, delete user table. Right now i'm currently just working on a table that shows what I have in my database and options to edite, delete, or add.
I have 2 tables in my database.
Links Table with the fields of : PID, LinkName, AnchorText, CategoryID, CategoryName
linkCategory table with the fields of : CategoryID, CategoryName
here's what I have so far.... and it's not showing up at all. No errors or anything.
<?php
// acquire shared info from other files
include("dbconn.inc.php"); // database connection
include("shared.php"); // stored shared contents
// make database connection
$conn = dbConnect();
print $HTMLHeader;
print $PageTitle;
?>
<script>
function confirmDel(title, pid) {
// javascript function to ask for deletion confirmation
url = "admin_delete.php?pid="+pid;
var agree = confirm("Delete this item: <" + title + "> ? ");
if (agree) {
// redirect to the deletion script
location.href = url;
}
else {
// do nothing
return;
}
}
</script>
<?php
// Retrieve the product & category info
$sql = "SELECT Links.PID, Links.AnchorText, linkCategory.CategoryName FROM Links, linkCategory where Links.CategoryID = linkCategory.CategoryID order by linkCategory.CategoryName";
$stmt = $conn->stmt_init();
if ($stmt->prepare($sql)){
$stmt->execute();
$stmt->bind_result($PID, $Title, $CategoryName);
$tblRows = "";
while($stmt->fetch()){
$Title_js = htmlspecialchars($Title, ENT_QUOTES); // convert quotation marks in the product title to html entity code. This way, the quotation marks won't cause trouble in the javascript function call ( href='javascript:confirmDel ...' ) below.
$tblRows = $tblRows."<tr><td>$Title</td>
<td>$CategoryName</td>
<td><a href='admin_form.php?pid=$PID'>Edit</a> | <a href='javascript:confirmDel(\"$Title_js\",$PID)'>Delete</a> </td></tr>";
}
$output = "<table border=1 cellpadding=4>\n
<tr><th>Title</th><th>Category</th><th>Options</th></tr>\n".$tblRows.
"</table>";
$stmt->close();
} else {
$output = "Query to retrieve product information failed.";
}
$conn->close();
?>
<?= $SubTitle_Admin ?>
<br>
| Add a new item |<br>
<?php echo $output ?>
<?php print $PageFooter; ?>
</body>
</html>
This is my first page, I still have to put in the PHP for edit, update, and delete... but can't even get my main page to show up. A bit lengthy, but I need to get this done. If anyone could help me out, or point me the right direction... I would be grateful. Here is a link to what it should look like http://omega.uta.edu/~cyjang/ctec4321/lab/productList2/admin_productList.php. When I try to pull my own up it's a blank page... like this: http://omega.uta.edu/~dxh6110/4321/in%20class/linksadmin/admin_productList.php
