下面是一个示例&mdash；测试和工作。

SQL查询是：

AND ({$wpdb->posts}.post_content != \'\' OR {$wpdb->posts}.post_excerpt != \'\')

<?php
// This would be in functions.php or somewhere else where appropriate.
function posts_where_require_content_or_excerpt( $where, $wp_query ) {
    global $wpdb;

    $where .= " AND (" .
        " {$wpdb->posts}.post_content != \'\'" .
        " OR {$wpdb->posts}.post_excerpt != \'\'" .
    ")";

    return $where;
}


// -- SAMPLE IMPLEMENTATION --

add_filter( \'posts_where\', \'posts_where_require_content_or_excerpt\', 10, 2 );
query_posts( array(
    \'post_type\'           => \'post\',
    \'posts_per_page\'      => 5,
    \'ignore_sticky_posts\' => true,
) );
remove_filter( \'posts_where\', \'posts_where_require_content_or_excerpt\', 10, 2 );

if ( have_posts() ) {
    echo \'<ul>\';

        while ( have_posts() ) {
            the_post();

            echo \'<li>\';

                echo \'<h2>\'; the_title(); echo \'</h2>\';
                echo \'<p>\'; the_excerpt(); echo \'</p>\';

                printf( \'<p><a href="%s">Read More &rarr;</a></p>\',
                    esc_url( get_permalink() ) );

            echo \'</li>\';
        }

    echo \'</ul>\';

    //the_posts_pagination(); // Needs extra work.
}

wp_reset_query();
