I am building a navigation menu which lists all my categories and subcategories. The problem is it returns only one of these and not all. I have the categories echoed inside the while loop so I'm not sure why it's only showing one result and not all:
<?php
$query = mysql_query("
SELECT * FROM categories_parent");
while ($row = mysql_fetch_assoc($query)) {
$id = $row['id'];
$name = $row['name'];
$slug = $row['slug'];
$childStatus = $row['child_status'];
// if has child categories
if ($childStatus == "1") {
echo "<li class='dir'><a href='category.php?slug=$slug'>$name</a>";
echo "<ul id='dropdown'>";
$query = mysql_query("
SELECT * FROM categories_child WHERE parent=$id");
while ($row = mysql_fetch_assoc($query)) {
$id = $row['id'];
$name = $row['name'];
$slug = $row['slug'];
echo "<li><a href='category.php?slug=$slug'>$name</a></li>";
}
echo "</ul>";
echo "</li>";
}
// if singular parent
else {
echo "<li><a href='category.php?slug=$slug'>$name</a></li>";
}
}
?>
