showing single posts from categories revisited

  • Hi,

    I just found Michael H’s very nice solution to get a single post form each category on your page.

    <?php // cycle through categories, print 1 post for each category
$categories=get_categories('orderby=name&order=ASC');
  foreach($categories as $category) {
      $posts=get_posts('showposts=1&cat='. $category->term_id);
      if ($posts) {
        echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
        foreach($posts as $post) {
          setup_postdata($post); ?>
          <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
          <?php
        } // foreach($posts
      } // if ($posts
    } // foreach($categories
?>

    It’s working magic, but I just need it even more specific. I cannot figure out how to omit categories from this query. I don’t want to show the ‘uncatagorised’ category for instance.

    To make it even more complicated I would like to omit the category that has most recently been posted in as well. Anyone any ideas?

    get_categories() has a exclude parameter

    I would like to omit the category that has most recently been posted in

    might be possibly with an extra get_posts() snippet;

    replace:

    $categories=get_categories('orderby=name&order=ASC');

    with:

    $exclude = '1'; //exclude 'uncategorized'//
$last = get_posts('numberposts=1'); //get the last post
$last_cats = get_the_category($last[0]->ID); //get the category(ies) from the last post and add to the exclude list//
foreach($last_cats as $last_cat) {
$exclude .= ','.$last_cat->term_id;
}
$categories=get_categories('orderby=name&order=ASC&exclude='.$exclude);

    (one post per category with some excludes)
