hi
i have a site with say 3 categories, two are children of the other
e.g.
fruit (id 3)
-- apples (id 4)
-- pears (id 6)
For all posts within the category "apples" I want to display the word "apples" and a link to that category page.
I need some code that says something like "for parent category 3 display the name of it's children and the relevant link".
I've looked at various functions but none seem to do this? Maybe the nearest is "get_the_category" but I'm unsure how to code it exactly.
Any help gratefully received

ok i've found this thread http://wordpress.org/support/topic/140469?replies=29 and this code ALMOST does what I want:
<?php
/*
*/
//exclude these from displaying
$exclude = array("Project", "London", "News");
//set up an empty categorystring
$catagorystring = '';
//loop through the categories for this post
foreach((get_the_category()) as $category)
{
//if not in the exclude array
if (!in_array($category->cat_name, $exclude))
{
//add category with link to categorystring
$catagorystring .= '<a href="'.get_bloginfo(url).get_option('category_base').'/'.$category->slug.'">'.$category->name.'</a>, ';
}
}
//strip off last comma (and space) and display
echo substr($catagorystring, 0, strrpos($catagorystring, ','));
?>
All i need is for the $exclude to be an $include and for the code to say something like "include child of fruit" rather than excluding specific categories.
Can anyone help?

Here you go - does exactly what you want
//set up an empty categorystring
$catagorystring = '';
// get all categories
foreach(get_the_category() as $category) {
// if category parent is 3 (fruit) then add this category to the string
if ($category->category_parent == 3) {
$catagorystring .= '<a href="'.get_bloginfo('url') . "/category" . '/' . $category->slug . '">' . $category->name . '</a>, ';
}
}
//strip off last comma (and space)
echo substr($catagorystring, 0, strrpos($catagorystring, ','));
