这对我有用：

<?php

$args = array(
    'post_type' => 'event',
    'showposts' => 1,
    'orderby' => 'date',
    'meta_query' => array(
            array(
            'key' => 'sponsored_event',
            'value' => 1,
            'compare' => 'LIKE'
            )
        )
    );

    $the_query = new WP_Query( $args );
?>

    <?php if ( $the_query->have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>


            <a href="<?php the_permalink(); ?>"><div class="sponsored-event">
                <div class="sponsored-image" style="background-image: url(<?php the_field( 'event_image' ); ?>);">
                </div>
                <div class="sponsored-info">
                    <h2>Sponsored Event</h2>
                    <h1><strong><?php the_title(); ?></strong></h1>
                    <p><strong>Date</strong></p><br>
                    <p class="place"><?php the_field( 'event_location' ); ?></p>
                    <p class="time"><?php the_field( 'event_time' ); ?></p>
                    <p><?php the_field( 'excerpt' ); ?></p>
                </div>
            </div></a>


    <?php endwhile; else: ?>

<?php endif; ?>
