Question

我很难弄清楚如何在Wordpress中使用相同的分类“年”对一组帖子进行分组，而不使用单独的存档模板。

我终于设法让它与Wordpress一起工作，但现在我想把它翻译成木材，而我似乎无法做到这一点。谁能给我一些指示？

这是有效的wordpress代码

$date_now = date('Y-m-d H:i:s');
$ex_terms = get_terms( 'exhibition-year','orderby=name&order=desc' );

foreach ( $ex_terms as $ex_term ) {
    $member_group_query = new WP_Query(
        array(
            'post_type' => 'exhibition',
            'tax_query' => array(
                array(
                'taxonomy' => 'exhibition-year',
                'field' => 'slug',
                'terms' => array( $ex_term->slug ),
                'operator' => 'IN'
                )
            ),
            'meta_query'        => array(
                array(
                'key'           => 'date_end',
                'compare'       => '<',
                'value'         => $date_now,
                'type'          => 'DATETIME'
                )
            )
        )
    );

    if($ex_term->slug <= date('Y')){
    ?>
        <h2><?php echo $ex_term->name; ?></h2>
        <ul>
        <?php
        if ( $member_group_query->have_posts() ) : while ( $member_group_query->have_posts() ) : $member_group_query->the_post(); ?>
            <li><?php echo the_title(); ?></li>
        <?php endwhile; endif; ?>
        </ul>
        <?php
        // Reset things, for good measure
        $member_group_query = null;
        wp_reset_postdata();
    }
}

期望的结果应该与此类似，我只显示标题。但它应该包含整个postdata。

我调查过：

请帮助，这让我疯了：）

对您的查询进行了两处更改

元查询中的当前时间戳

在将其与当前年份进行比较之前转换为integer类型

$ current = current_time（'timestamp'）; $ ex_terms = get_terms（'exhibition-year'，'orderby = name＆amp; order = desc'）;

foreach（$ ex_terms as $ ex_term）：

$member_group_query = new WP_Query(
    array(
        'post_type' => 'exhibition',
        'tax_query' => array(
            array(
                'taxonomy' => 'exhibition-year',
                'field' => 'slug',
                'terms' => array( $ex_term->slug ),
                'operator' => 'IN'
            )
        ),
        'meta_query'        => array(
            array(
                'key'           => 'date_end',
                'compare'       => '<',
                'value'         => $current
            )
        )
    )
);

if( (int)$ex_term->slug <= date('Y')):

    echo '<h2>'.$ex_term->name.'</h2>';
    echo '<ul>';

    if ( $member_group_query->have_posts() ) : 

        while ( $member_group_query->have_posts() ) : $member_group_query->the_post();

            echo '<li>'.get_the_title().'</li>';

        endwhile; 

    endif;

    echo '</ul>';

endif;

$member_group_query = null;
wp_reset_postdata();

endforeach;

希望这有帮助。

@CKDT这是未经测试的，但这是在Timber中的重写...

PHP

$date_now = date('Y-m-d H:i:s');
$ex_terms = Timber::get_terms( 'exhibition-year','orderby=name&order=desc' );

foreach ( $ex_terms as &$ex_term ) {
    $member_group_query = Timber::get_posts(
    array(
        'post_type' => 'exhibition',
        'tax_query' => array(
            array(
            'taxonomy' => 'exhibition-year',
            'field' => 'slug',
            'terms' => array( $ex_term->slug ),
            'operator' => 'IN'
            )
        ),
        'meta_query'        => array(
            array(
            'key'           => 'date_end',
            'compare'       => '<',
            'value'         => $date_now,
            'type'          => 'DATETIME'
            )
        )
    ));
    $ex_term->events = $member_group_query;
    if( $ex_term->slug <= date('Y') ){
        $ex_term->past = true;
    }
}
$context['ex_terms'] = $ex_terms;
Timber::render('my-file.twig', $context);

Twig文件

{% for term in ex_terms %}
    {% if term.past %}
        <h2>{{ term.name }}</h2>
        <ul>
        {% for post in term.events %}
            <li>{{ post.title }}</li>
        {% endfor %}
        </ul> 
{% endfor %}
