recursive function category database

Question

Answer 1

What you need to do, is build a recursive function. That is, a function that calls itself within. An example:

function getCategories($parent=0) {
    $res = mysql_query("SELECT * FROM categories WHERE category_parent = '$id' ORDER BY left ASC");
    if (mysql_num_rows($res) > 0) {
        $category = mysql_fetch_object();
        echo '
';
        echo '
' . $category->category_name . '';
        getCategories($category->category_id);
        echo '
';
    }
}

If I've made any typos in regards to table and column names then obviously swap them out for the correct values.
