Displaying multiple post types on home page

Question

I've read several examples of how to do this but I still can't get it to work - each time I use get_posts() it seems to only keep and display the first set of results.

loop.php

function home_index() {

global $post;

echo '<ul>';

$args = array(
    'numberposts'     => 3,
    'offset'          => 0,
    'orderby'         => 'post_date',
    'order'           => 'DESC',
    'post_type'       => 'gp_news',
    'post_status'     => 'publish',
    'meta_key'        => '_thumbnail_id',
    'meta_value'      => 1,
    'meta_compare'    => '>='
);

$myposts = get_posts( $args );

foreach( $myposts as $post ) {
    setup_postdata($post);
    echo '<li>';

    if ( has_post_thumbnail() ) {
        the_post_thumbnail( 'homepage-thumbnail' );
    }
    ?>
    <h1>news <a href="<?php the_permalink(); ?>" title="Permalink to <?php esc_attr(the_title()); ?>" rel="bookmark"><?php the_title(); ?></a></h1>
    <?php the_excerpt(); ?>
    <a href="<?php the_permalink(); ?>">Continue...</a>
    <?php
    echo '</li>';
}

$args = array(
    'numberposts'     => 1,
    'offset'          => 0,
    'orderby'         => 'post_date',
    'order'           => 'DESC',
    'post_type'       => 'gp_competitions',
    'post_status'     => 'publish',
    'meta_key'        => '_thumbnail_id',
    'meta_value'      => 1,
    'meta_compare'    => '>='
);

$myposts = get_posts( $args );

foreach( $myposts as $post ) {
    setup_postdata($post);
    echo '<li>';

    if ( has_post_thumbnail() ) {
        the_post_thumbnail( 'homepage-thumbnail' );
    }
    ?>
    <h1>competition <a href="<?php the_permalink(); ?>" title="Permalink to <?php esc_attr(the_title()); ?>" rel="bookmark"><?php the_title(); ?></a></h1>
    <?php the_excerpt(); ?>
    <a href="<?php the_permalink(); ?>">Continue...</a>
    <?php
    echo '</li>';
}

echo '</ul>';   

}

Answer 1

I was able to query two custom post types by using this line:

AND wposts.post_type IN ('custom_post_type_1', 'custom_post_type_2')

This worked for my situation, where each custom post type was being sorted by the same meta_key

Answer 2

You shouldn't have to do all that. The below function will allow you to control what shows up in the default loop without having to rebuild the query itself

function cpt_pre_get_posts_filter( $query ) {
  global $wp_query;

  if ( !is_preview() && !is_admin() && !is_singular() && !is_404() ) {
    if ($query->is_feed) {
    /* set your post types in the array below */
    } else {
      $my_post_type = get_query_var( 'post_type' );
      if ( empty( $my_post_type ) )
        $query->set( 'post_type' , 'my-post-type', 'my-other-post-type' );
    }
  }

  return $query;
}
add_filter( 'pre_get_posts' , 'cpt_pre_get_posts_filter' );

So I finally figured out 2 ways of doing it. The first way is...

global $wp_query;

$args = array(
    array(
        'numberposts'     => 3,
        'offset'          => 0,
        'orderby'         => 'post_date',
        'order'           => 'DESC',
        'post_type'       => 'gp_news',
        'post_status'     => 'publish',
        'meta_key'        => '_thumbnail_id',
        'meta_value'      => 1,
        'meta_compare'    => '>='
    ),
    array(
        'numberposts'     => 1,
        'offset'          => 0,
        'orderby'         => 'post_date',
        'order'           => 'DESC',
        'post_type'       => 'gp_competitions',
        'post_status'     => 'publish'
    )
);

echo '<ul class="hp_minifeatured">';
$temp_query = clone $wp_query;
for($index = 0; $index < count($args); $index++) {
    $myposts = new WP_Query( $args );

    if($myposts->have_posts()) {
        while($myposts->have_posts()) {
            $myposts->the_post();
            echo '<li>';

            if ( has_post_thumbnail() ) {
                the_post_thumbnail( 'homepage-thumbnail' );
            }
            ?>
            <p><?php echo($args[$index]['post_type']); ?></p>
            <h1><a href="<?php the_permalink(); ?>" title="Permalink to <?php esc_attr(the_title()); ?>" rel="bookmark"><?php the_title(); ?></a></h1>
            <?php the_excerpt(); ?>
            <a href="<?php the_permalink(); ?>">Continue...</a>
            <?php
            echo '</li>';
        }
    }
}
$wp_query = clone $temp_query;  
echo '</ul><div class="clear"></div>';

...but this results in using multiple queries.

Another way is...

global $wpdb;
global $post;

$querystr = "(SELECT wp_posts.* FROM $wpdb->posts wp_posts, $wpdb->postmeta wp_postmeta WHERE wp_posts.ID = wp_postmeta.post_id and wp_posts.post_status = 'publish' and wp_posts.post_type = 'gp_news' and wp_postmeta.meta_key = '_thumbnail_id' and wp_postmeta.meta_value >= 1 ORDER BY wp_posts.post_date DESC LIMIT 3) union (SELECT wp_posts.* FROM $wpdb->posts wp_posts, $wpdb->postmeta wp_postmeta WHERE wp_posts.ID = wp_postmeta.post_id and wp_posts.post_status = 'publish' and wp_posts.post_type = 'gp_competitions' and wp_postmeta.meta_key = '_thumbnail_id' and wp_postmeta.meta_value >= 1 ORDER BY wp_posts.post_date DESC LIMIT 1)";
$pageposts = $wpdb->get_results($querystr, OBJECT);

if ($pageposts) {
    foreach ($pageposts as $post) {
        setup_postdata($post);
        echo '<li>';
        if ( has_post_thumbnail() ) {
            the_post_thumbnail( 'homepage-thumbnail' );
        }
        ?>
        <h1><a href="<?php the_permalink(); ?>" title="Permalink to <?php esc_attr(the_title()); ?>" rel="bookmark"><?php the_title(); ?></a></h1>
        <?php the_excerpt(); ?>
        <a href="<?php the_permalink(); ?>">Continue...</a>
        <?php
        echo '</li>';
    }
}

Answer 4

$args = aray(
'post_type' => array ( 'post', 'page','event')
);
query_posts($args);
