<p>In the code below, the echo at the top returns true, but the echo at the bottom returns nothing. Apparently the code in between is causing me to lose a reference to the $_post variable?</p> <pre><code><?php echo "in category: ".in_category('is-sidebar'); //RETURNS TRUE if (!get_option('my_hide_recent')) { $cat=get_cat_ID('top-menu'); $catHidden=get_cat_ID('hidden'); $myquery = new WP_Query(); $myquery->query(array( 'cat' => "-$cat,-$catHidden", 'post_not_in' => get_option('sticky_posts') )); $myrecentpostscount = $myquery->found_posts; if ($myrecentpostscount > 0) { ?> <div class="menu"><h4><?php if ($my_sidebar_heading_recent !=="") { echo $my_sidebar_heading_recent; } else { echo "Recent Posts";} ?></h4><ul> <?php global $post; $current_page_recent = get_post( $current_page ); $myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$catHidden",'showposts' => $my_recent_count)); foreach($myrecentposts as $idxrecent=>$post) { if($post->ID == $current_page_recent->ID) { $home_menu_recent = ' class="current_page_item'; } else { $home_menu_recent = ' class="page_item'; } $myclassrecent = ($idxrecent == count($myrecentposts) - 1 ? $home_menu_recent.' last"' : $home_menu_recent.'"'); ?> <li<?php echo $myclassrecent ?>><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li> <?php } ; if (($myrecentpostscount > $my_recent_count) && $my_recent_count > -1){ ?><li><a href="<?php bloginfo('url'); ?>/site-map">View all</a></li><?php } ?></ul></div> <?php } } global $sitemap; echo "in category: ".in_category('is-sidebar'); //RETURNS NOTHING </code></pre>

1. COImpossible to tell without knowing what `in_sidebar` does exactly. Maybe the second parameter is a `&` reference and gets altered? Maybe the function imports global variables that are being changed in the block?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
