In reply to: How do I show latest post from X random categories?I found the solution. The code below will do the trick:
<?php // grab 4 random categories $cats = ''; $categories = get_categories(); $rand_keys = array_rand($categories, 4); foreach ($rand_keys as $key) { $cat = $categories[$key]->term_id; $nam = $categories[$key]->cat_name; // grab the latest post from each of the 4 random categories $latest = new WP_Query("cat=$cat&showposts=1"); while($latest->have_posts()) : $latest->the_post(); ?> <small>Latest in <a href="#"><?php echo $nam; ?></a></small> <h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3> <?php the_excerpt(); ?> <?php endwhile; ?> <?php } ?>Forum: Plugins
In reply to: preview mode for already published posts/pagesSeeing as how this was last posted to 9 months ago, maybe something new has happened.
I too would like to be able to modify a live post or page and then preview the changes before I make those changes live.
I’ve done a lot of searching but haven’t found anything on this. Can anyone at WordPress or in the community speak to this?

In reply to: display number of posts per categoryJohn,
I posted a thank you on your blog for your insight on this. I was looking for more control over the output of the number of posts for each category. Instead of the default output:
Uncategorized (2)
I wanted something like this:
Uncategorized // 2 posts
After looking at your code I came up with this:
foreach (get_categories(array('hide_empty'=>false)) as $category) { echo '<li><a href="' . get_bloginfo('wpurl') . '/category/' . $category->category_nicename . '/">' . $category->cat_name . '</a> // ' . $category->count . 'posts</li>'; }Simply drop this code in between some
<ul>tags where you want your category list to appear and you’re set. It’s also possible to wrap the “number of posts” piece in a<span>or similar tag to style it differently.Forum: Themes and Templates
In reply to: Display the number of posts beside categoryIf you are content with showing it like this:
Category (x)
Category (y)Where x and y are the number of posts in the category, then just be sure to include the “show_count” parameter in the
wp_list_categoriesfunction:<?php wp_list_categories('show_count=1'); ?>As for displaying the posts in a fancier way, paste the following snippet of code where you want to show your categories:
<ul> foreach (get_categories(array('hide_empty'=>false)) as $category) { echo '<li><a href="' . get_bloginfo('wpurl') . '/category/' . $category->category_nicename . '/">' . $category->cat_name . '</a> (' . $category->count . ' posts)</li>'; } </ul>This will output:
Category Name (X posts)
You can wrap the (X posts) piece in a <span> tag or other HTML tag if you want to style it separately. In my case, I was looking to position the category name to the left and the number of posts to the right.
Special thanks to John Herren for this one.

In reply to: Number Of Results In SearchIf this topic still needs an answer, try this. No plug-in required, and deceptively simple. Just add this line of code before your while loop:
$hit_count = $wp_query->found_posts;For example, my search results page looks like this:
<?php if (have_posts()) : ?> <?php $hit_count = $wp_query->found_posts; // count # of search results ?> <p>Your search for <b>'<?php the_search_query(); ?>'</b> returned <?php echo $hit_count . ' results'; ?></p>.
.

In reply to: Number of Search ResultsI know this topic got dropped a while ago, but I found an answer:
To count the total number of search results for a search that has paginated results, simply add this above your loop:
$hit_count = $wp_query->found_posts;For example, my search results page looks like this:
<?php if (have_posts()) : ?> <?php $hit_count = $wp_query->found_posts; // count # of search results ?> <p>Your search for <b>'<?php the_search_query(); ?>'</b> returned <?php echo $hit_count . ' results'; ?></p>.

In reply to: Problem with “current_page_item” navigation highlightingmunzli,
Your solution worked for me. However, instead of selecting a “Posts page” from the WordPress Options->Reading menu, I use a custom page template that lists posts from a single category. The page ID for this is 58, so I modified your code to read:
if ($page->ID == $current_page || ($current_page == 0 && $page->ID == '58'))This change (on line 512 of classes.php) saved me a headache. Thanks so much.
btw – running version 2.2.3

In reply to: Trouble with query_posts: multiple pages of repeated contentThe error went away, and God knows why. I suspect it might have been a conflict with Lutz Schroeer’s Pagebar plug-in, which I swapped out in favor of the superior Pagebar Navigation plug-in by Andy Staines.

In reply to: Get title for Page parentIn that last bit of code, the only change is from
$post->IDto
$post->post_parentForum: Themes and Templates
In reply to: Get title for Page parentGoing off of sojweb’s last bit of code, I came up with:
echo '<a href="'.get_permalink($post->post_parent).'">'.get_the_title($post->post_parent).'</a>';This does the trick of displaying the parent page’s title if you are on a subpage of the parent or on the parent itself.
Alternatively, you can make it a heading by swapping in <h2> tags for the
<a>tags.
