Display latest post from category *with slug*

    I’ve seen this topic here about how to display the last post from a particular category and I’d like to do this but using categories with slugs rather than IDs. I’ve got this request here:

    <h4 class="center">This Week</h4>
<?php $cat_id = 0;
$latest_cat_post = new WP_Query( array('posts_per_page' => 1, 'category__in' => array($cat_id)));
if( $latest_cat_post->have_posts() ) : while( $latest_cat_post->have_posts() ) : $latest_cat_post->the_post();  ?>

<h4><?php the_title(); ?></h4>	

<?php the_content(); ?>

<?php endwhile; endif; ?>

    I’d like to know how to either find out the ID of categories with slugs switched on, or how to have this request parse a slug. FYI, the page this is going into is actually a specific category template itself.

    Structure:
    root
    – events
    |_ event-reviews
    |_ event-previews
    – listings

    I’m currently altering the category-events template and trying to have it show the last listings post in the sidebar.

    I hope that’s enough context. Thanks in advance.

    To use a slug rather than an id; just change category__in to category_name.

    Then, make sure to use a slug variable (named whatever you want) instead of the id variable.

    So, we get this:

    <h4 class="center">This Week</h4>
<?php $cat_slug = 'my_cat_slug';
$latest_cat_post = new WP_Query( array('posts_per_page' => 1, 'category_name' => $cat_slug));
if( $latest_cat_post->have_posts() ) : while( $latest_cat_post->have_posts() ) : $latest_cat_post->the_post();  ?>

<h4><?php the_title(); ?></h4>	

<?php the_content(); ?>

<?php endwhile; endif; ?>

    You can learn more about ‘category parameters’ in a WP Query from the Codex.

    So I have this code on a page now rather than a category, to simplify matters. It is spitting out posts in the correct quantity but it appears to just be spitting out all posts regardless of category. Any ideas?

    <h4 class="center">This Week</h4>
<?php $cat_id = 'event-previews';
$latest_cat_post = new WP_Query( array('posts_per_page' => 1, 'category__name' => array($cat_id)));
if( $latest_cat_post->have_posts() ) : while( $latest_cat_post->have_posts() ) : $latest_cat_post->the_post();  ?>

<h6 class="center"><?php the_title(); ?></h6>
<div class="listings">
<?php the_content(); ?>
</div>
<?php endwhile; endif; ?>

    Take a closer look at my code.

    'category__name' => array($cat_id)

    Should be…

    'category_name' => $cat_slug

    Also:

    $catid = 'event-previews';

    Should be…

    $cat_slug = 'event-previews';

    It seems you just swapped category__in with category_name… without fully inspecting the differences between the code snippets.
