I have the following category structure for a site that I am working on:
2008
- Group 1
-- Review 1
-- Review 2
- Group 2
-- Review 1
-- Review 2
2009
- Group 1
-- Review 1
-- Review 2
- Group 2
-- Review 1
-- Review 2
I want to display the category listing page for all the categories called "review" in a different way. Therefore how to do I check for whether the category is a 3rd level category i.e. it has a parent and grandparent?
Getting round this another way I have managed to fix this however I am now using the code below in order to display the category names of child categories of the current category.
<?php $descendants = get_categories(array('child_of' => 6)); ?>
<?php foreach ($descendants as $child) { ?>
<li><?php echo $child->cat_name; ?></li>
<?php } ?>My questions is, is how do I alter this so that it only brings back the immediate child categories of the current category, rather than child and grandchild categories?
More to your first question:
<?php
$test_for_level = intval(3);
$last_level = 0;
$cat_to_test = 6;
$category=get_category($cat_to_test);
for ( $counter = 1; $counter <= $test_for_level; $counter += 1) {
if ($category->category_parent) {
$category=get_category($category->category_parent);
$last_level = $counter;
}
}
$last_level +=1;
if ($last_level == $test_for_level) {
echo '<p>Category ' . $cat_to_test . ' is at level ' .$last_level . '</p>';
} else {
echo '<p>Category ' . $cat_to_test . ' is NOT at level ' .$test_for_level . '</p>';
}
?>Add depth=x, where x is the number of levels you wish to show.
Thanks for that MichaelH - works a treat.
Regarding my second question. The depth function doesn't seem to work. It is not a parameter of the function according to this page?

Anyone have any ideas?
That depth= seems to only work with wp_list_categories and wp_dropdow_categories and both pass that argument to walk_category_tree.
At the moment when I click on category 2008 / 2009 it show the immediate children (Group 1, Group 2) but also the grand children (Review 1, Review 2). It is OK when on the Group 1 or Group 2 cat pages. How do I stop it returning Grand Children?
Michael is right, the depth var only works with the two he listed...my apologies.
I'm not sure how to limit depth with the wp_get param.
