Data not printing in table


Recommended Posts

I have this script:

$table = "<table border=1>\n";

$sql = "SELECT id FROM categories LIMIT 1";
$result = $db->query($sql);
while($row = $db->fetch($result)){
	$id = $row['id'];
$table .= "

$table .= "</table>";
echo $table;


function crumbs_category2($cat_id, $level=0) {  
	global $db;
	$sql = "SELECT parentid, name FROM categories WHERE id = $cat_id";
	$result = $db->query($sql);
	list ($p, $n) = $db->fetchRow($result);

	if ($p != '0') $this->crumbs_category2($p, $level+1);
	echo ($p == '0') ? "$n " : "- $n ";   


and it outputs this:

Fashion Jewelry <table border=1>







Why is this data not printing in the table?
