Question

I have a table set up with a column titled has_sub which contains a tinyint value of 1 or 0 depending on whether the subcategory has another level or not. 1 = has another level and 0 = no other level.

The problem I am having is that I cannot seem to get my anchors hrefs to change depending on the has_sub field (please see the following code)

$dbc = mysql_connect($db_host,$db_user,$db_pass);
$sdb = mysql_select_db($db_database);

$category = mysql_real_escape_string($_GET['category']);

$query = "SELECT subcategory_name, has_sub FROM subcategories WHERE subcategory_parent = '$category'";
$result = mysql_query($query, $dbc)
or die (mysql_error($dbc));

while($row = mysql_fetch_array($result)) {

$subcatname = $row["subcategory_name"];
$hassub = $row["has_sub"];

if($hassub=='1')
echo "<li><a href='getsubsubs.php?category=$subcatname'>$subcatname</a></li>";

else
echo "<li><a href='listings.php?category=$subcatname'>$subcatname</a></li>";

}

As I am a beginner, chances are that I am missing something quite basic but can’t seem to figure it out. I have been looking through the documentation to no avail. Many thanks in advance.

Result of print_r($row): (from OP comment)

Array ( 
    [0] => Alarm Systems 
    [subcategory_name] => Alarm Systems 
    [1] => 0 
    [has_sub] => 0 
) 
Array ( 
    [0] => Building Interiors and Services 
    [subcategory_name] => Building Interiors and Services 
    [1] => 1 
    [has_sub] => 1 
)

Everything is correct so check input on the database for errors.
