Question

我在侧栏上有一个带日历的活动页面。每次用户点击日期时，我都会通过我创建的API端点加载该日期的所有事件。到目前为止一切都很好，但我有一个分页问题。如果用户刚刚进入事件页面分页将完美，但是当用户点击日历以通过API加载事件时，它会破坏分页并始终将next_post_link作为第2页返回。只是因为我也在设置中配置了posts_per_page与自定义查询相同，但它没有帮助。

<?php

function get_events(WP_REST_Request $request)
{
    global $post;
    $event_date = $request["event_date"];
    $paged = ($request["paged"]) ? $request["paged"] : 1;
    $date = '';

    $args = array(
        'post_type'      => 'event',
        'posts_per_page' => 3,
        'paged'          => $paged,
        'meta_key'       => 'event_date',
        'meta_value'     => $event_date,
        'meta_compare'   => '>=',
        'orderby'        => 'meta_value',
        'order'          => 'ASC'
    );
    $the_query = new WP_Query( $args );

    ob_start();

    include(locate_template('events_template.php'));

    $events = ob_get_contents();
    ob_get_clean();
    return $events;
}

活动模板：

<div class="posts-container">
    <?php if ( $the_query->have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
        <div>
            <?php
                //Here we group events by event_date and add the date at the top.
                $event_date =  get_post_meta( $post->ID, 'event_date', true );
                if ( $event_date != $date )
                {
                    $event_date_formatted = date( 'l, F jS, Y', strtotime( $event_date ) );
                    echo "<p class='page-header'><strong>$event_date_formatted</strong></p>";
                    $date = $event_date;
                }


            ?>
            <div class="event ath-card">
                <h4><?php the_title(); ?></h4>
                <p><?php echo get_post_meta( $post->ID, 'event_location', true ) ?></p>
                <p><?php echo get_post_meta( $post->ID, 'event_details', true ) ?></p>
            </div>
        </div>
    <?php endwhile; endif; ?>
</div>

<div class="loader text-center hidden">
    <i class="fa fa-spinner fa-pulse fa-3x fa-fw"></i>
</div>

<div class="div pagination-container text-center">
    <?php
        //always returns page number 2.
        //I run the exact query in the page itself and it works fine
        next_posts_link( '<button class="ath-btn ath-btn-info">LOAD MORE</button>', $the_query->max_num_pages );
    ?>
</div>

好吧，我无法以正常方式解决问题，但幸运的是

 <?php $the_query->max_num_pages ?>

返回了正确的总页数，因此我用它来手动设置下一个帖子链接。

我补充说：

if($paged < $the_query->max_num_pages)
{
    $next_page = $paged + 1;
}
else
{
    $next_page = null;
}

而且：

<?php if ( $next_page ) : ?>
    <a href="http://localhost:8888/water/wp-json/events/v1/events/page/<?php echo $next_page ?>/?event_date=<?php echo $request["event_date"] ?> ">
        <button class='ath-btn ath-btn-info'>LOAD MORE</button>
    </a>
<?php endif; ?>

WordPress API分页只返回两页。
