Listing Posts from Two Categories

  • I am attempting to list posts that belong to two specific categories. I have attempted to create the code myself, but I’m not very experienced with PHP

    <?php

//The Query
query_posts(array('category__and' => array(8,387)));

//The Loop
if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

        <li><a href="<?php the_permalink(); ?>">
          <?php the_title(); ?>
          </a>  </li>
 <?php endwhile; else: ?>
 <?php endif; ?>

    This is the code I am using, but it comes up with only a blank page. I would appreciate any help, even if it’s suggesting a plugin.

  • your code would show only posts that have these two categories together at the same time, i.e. posts with cat8 AND cat387.

    it sounds that you are trying to show posts that belong to either one or both of these categories, i.e. cat8 AND/OR cat387.

    query_posts('cat=8,387');

    that’s exactly what I want to do — show posts that only exist in both categories, but the page shows up blank, so something’s missing from the code or I’ve typed something incorrectly.

    the code is correct (identisch with the line from the codex) and works ok in my test setup.

    are you sure that you have posts that are categorized with these two categories?
    what if you make a list of the posts in cat8 and a list of the posts in cat387: are there posts that appear in both lists?

    are you running other queries before this one?
    maybe in the sidebar?
    if so try to use ‘wp_reset_query();’ before your code.

    I have four posts that appear in both categories and I tried using the wp_reset_query before my code and the page is still completely blank. I’m using the ExecPHP

    I should mention that I am not using this code in a post, but on a page, that shouldn’t matter right?

    I’ve been playing with the code and the only time the page comes up blank is if I include the loop. Without the loop, I receive PHP errors, but the page at least comes up. I’m curious to know if it would be better to search out a plugin that might work for this as I’d like to execute several queries on the page (at least three)
