【WordPress】query_postsの代替としてのget_postsについて

Last updated at Posted at 2014-07-17

結論

get_posts()を使い、setup_postdata()し、wp_reset_postdata()する。

書き比べ

query_posts()版

<?php
    query_posts('category_name=' . $category->slug . '&orderby=title&order=ASC');
    if(have_posts()):
        while(have_posts()):
?>
            <h4><?php the_title(); ?>"></h4>
            <?php the_contents(); ?>
<?php
        endwhile;
    endif;
?>

get_posts()版

<?php
    $post_args = array(
        'category'  => $category->cat_ID
       ,'orderby'   => 'title'
       ,'order'     => 'ASC'
       ,'post_type' => 'post'
    );
    $shohin_posts = get_posts( $post_args );
    foreach($shohin_posts as $post) :
        setup_postdata( $post );
    ?>
        <h4><?php the_title(); ?>"></h4>
        <?php the_contents(); ?>
<?php
    endforeach; 
    wp_reset_postdata();
?>
