I am using this bit of code:
$args = array(
'orderby' => 'name',
'hierarchical' => 1,
'style' => 'none',
'taxonomy' => 'category',
'hide_empty' => 0,
'depth' => 1,
'title_li' => ''
);
$categories = get_categories($args);
What I am trying to do is to list only top level categories. When I am using this code I am getting all of them not just level one. Can someone help me?
There is no depth
argument for get_categories()
, you should try :
$args = array(
'orderby' => 'name',
'parent' => 0
);
parent
: (integer) Display only categories that are direct descendants (i.e. children only) of the category identified by its ID. This does NOT work like the 'child_of' parameter. There is no default for this parameter. [In 2.8.4]

soju post is very helpful, for to get category only 1 level subcategory we should just pass the category id that has subcategories . But if the subcategory have no any post then it doesnot shows but subcategory subcategory consist the post so add 'hide_empty' => 0, in the above condition it will look like
$args = array(
'taxonomy' => 'categories',
'parent' => 7,
'hide_empty' => 0,
);
Here is my script to get top level category names from within the loop. This will include top level categories that just have a child category checked, and are not explicitly checked themselves.
<?php
$categories = get_the_category();
$topcats = array();
foreach ($categories as $cat) {
if ($cat->parent != 0) $cat = get_term($cat->parent, 'category');
$topcats[$cat->term_id] = '<a href="/category/' . $cat->slug . '">' . $cat->name . '</a>';
}
echo implode(', ', $topcats);
?>
