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
