# Hide Child Category Posts

 * For many years, I have used a plug-in to hide child category posts but after 
   a recent upgrade to 3.1.2, this has stopped working and I have not been able 
   to find a replacement that works.
 * Can anyone advice how to achieve this?
 * **I only want posts for the current category to show.**
 * `while (have_posts()) : the_post(); if(in_category($cat)) {`
 * has been suggested but I don’t have $cat and can’t work out how to set it to 
   current_category.

 * Not sure but try getting the first category from the post.
 *     ```
       while (have_posts()) : the_post();
       $category = get_the_category();
       if( $category ) {
          $catid = $category->cat_ID;
       }
       ```
   
 * Or maybe:
 *     ```
       while (have_posts()) : the_post();
       if( is_category() ) {
          $category = get_the_category();
          $catid = $category->cat_ID;
       }
       ```

 * No joy… I think get_the_category() may need Post_ID as a parameter.
 * This is pretty crippling now so I may have to wind back to an early version where
   plug-ins work and stay there.
 * (Admin suffers in the same way. With several layers of sub-category, filter posts
   by category now returns many tens of pages because it includes every post from
   every child category – this was a dumb idea!).

 * The original plug-in, which has served fantastically for years, was very simply:
 *     ```
       <?php
       function kinderlose_where($where) {
         if ( is_category() ) {
           global $wp_query;
           $where = preg_replace('/.term_id IN \(\'(.*)\'\)/', '.term_id IN (\'' . $wp_query->query_vars['cat'] . '\')', $where);
         }
         return $where;
       }
   
       add_filter('posts_where', 'kinderlose_where');
       ?>
       ```
   
 * Is there an obvious reason why this no longer works?

 * It gets the first category of the current post unless you pass an ID in, as you
   are in the loop if there is a category it should return it?
 * Missed the [0]
    `$category[0]->cat_ID`
