How do I show child categories if in a parent category, and posts if in a child?

    I was hoping to do all of this within the category.php template, with help from the functions.php if needed.

    If my setup is:

    Parent 1
--Child 1
--Child 2
Parent 2
--Child 3
--Child 4
Parent 3
--Child 5
--Child 6

...and so on

    I would like to be able to do this:

    If I was viewing Parent 1 (or 2/3), it would show me Child 1 and Child 2. However, I don’t want to use wp_list_categories because for each Child, I would like to show a thumbnail (from a plugin function), the Child’s name, and the category description.

    If I was viewing Child 1 (or 2/3/4/5/6), it would show me the latest 2 posts using the standard Loop.

    I would like avoiding having to do this using hard-coded contitionals with the specific names of the categories, in case new ones will be added in the future.

    Any assistance will be appreciated. Thank you!

    Handiest is if you have an array of childcats, so you can use in_category() to display stuff or not.

    I wrote this function which gives you that array of childcategories, based on the name of the parent-category.

    // Get List of Child Categories
    function get_child_cats( $catname ) {
    $parentcat = get_cat_ID( ‘$catname’ );
    $subcat = get_categories( array(‘child_of’ => $parentcat ) );
    $cat_array = array();
    //array_push($cat_array, $parentcat); // add the parent cat to the array
    foreach ($subcat as $sc) {
    array_push($cat_array, $sc->cat_ID);
    }
    return $cat_array;
    }
