   Hello,

   I would like to know if it's somehow possible to add an argument to the get_the_category function to only display categories (child of a parent category) a post belongs to.

   E.g if my posts belongs to cat 1, 1>2, 3, 7
   I d'like to write get_the_category(catId=1) so that it will ouput me the category name 1>2

   Anything possibile ??

   Thanks a lot!

   Use get_categories

   Or this will only show child categories (use within the loop)
   

   <?php
   foreach((get_the_category()) as $category) {
   if($category->parent != 0){
   echo $category->cat_name . ' ';
   }
   }
   ?>

   If I use this solution, even the categories my post doesnt belong to will be shown ... no ?

   No, it will only show child categories that are assigned to the post.

   This is what I've done :

   <?php foreach((get_the_category()) as $chaine)
   { if($chaine->parent == 27){ echo $chaine->cat_name . ' ';  }
   }
   ?>

   It works...slighty modified but working.

   Thank you, you put me on the right tracks
