Question

我正在编写一个短代码，我想定位最近的＆＃34;事件＆＃34;。针对最近的＆＃34;事件＆＃34;我想做两件事。

能够应用特定的课程，以便我可以采用不同的方式（我不想使用first-child）。
将the_excerpt()添加到其中。

目前，短代码会拉动最近的4＆＃34;事件＆＃34;。所以最近需要我上面提到的。我想象它必须用＆＃34;计数＆＃34;但我还不完全确定，还在努力学习这些东西。

add_shortcode( 'show_events', 'events_query' );

function events_query() {
    $args = array(
        'posts_per_page' => 4,
        'category_name' => 'events',
    );
    $events_query = new WP_Query( $args );
    if ( $events_query->have_posts() ) :
        $html_out = '<article>';
        while ( $events_query->have_posts() ) :
            $events_query->the_post();
            // Do stuff with each post here
            $html_out .= '<div class="events-item"><div class="meta-date">' . Date('F j, Y') . '</div><div class="meta-info"><div class="meta-title"><h4><a href="' . get_permalink() . '">' . get_the_title() . '</a></h4></div>/div></div>';
        endwhile;
        $html_out .= '</article>';
    else : // No results
        $html_out = 'No Events Found.';
    endif;
    wp_reset_query();
    return $html_out;
}

修改

使用答案中的代码进行了更新：

add_shortcode( 'show_events', 'events_query' );

function events_query() {
    $args = array(
        'posts_per_page' => 4,
        'category_name' => 'events',
    );
    $events_query = new WP_Query( $args );
    if ( $events_query->have_posts() ) :
        $html_out = '<article>';
        $counter = 0;
        $event_class = 'events-item';
        while ( $events_query->have_posts() ) :
            if ( $counter == 0 ) {
                 $event_class = 'events-item most-recent';
            }
            $events_query->the_post();
            // Do stuff with each post here
            $html_out .= '<div class="' . $event_class . '"><div class="meta-date">' . Date('F j, Y') . '</div><div class="meta-info"><div class="meta-title"><h5><a href="' . get_permalink() . '">' . get_the_title() . '</a></h5></div></div>';

            if ( $counter == 0 ) {
                $html_out .= '<div class="meta-info">' . get_the_excerpt() . '</div>';
            }
            $html_out .= '</div>';
            $counter++;
        endwhile;
        $html_out .= '</article>';
    else : // No results
        $html_out = 'No Events Found.';
    endif;
    wp_reset_query();
    return $html_out;
}

嘿达伦，这又是我:) 您可以使用其他var $counter来检查它是否是第一篇文章这是代码

add_shortcode( 'show_events', 'events_query' );

function events_query() {
    $args = array(
        'posts_per_page' => 4,
        'category_name' => 'events',
    );
    $events_query = new WP_Query( $args );
    if ( $events_query->have_posts() ) :
        $html_out = '<article>';
        $counter = 0;

        while ( $events_query->have_posts() ) :
            $event_class = 'events-item';
            if ( $counter == 0 ) {
                 $event_class = 'events-item first-event, additiona-classes';
            }
            $events_query->the_post();
            // Do stuff with each post here
            $html_out .= '<div class="' . $event_class . '"><div class="meta-date">' . Date('F j, Y') . '</div><div class="meta-info"><div class="meta-title"><h4><a href="' . get_permalink() . '">' . get_the_title() . '</a></h4></div>/div>';

            if ( $counter == 0 ) {
                $html_out .= '<div class="meta-info">' . $post->post_excerpt . '</div>';
            }
            $html_out .= '</div>';
            $counter++;
        endwhile;
        $html_out .= '</article>';
    else : // No results
        $html_out = 'No Events Found.';
    endif;
    wp_reset_query();
    return $html_out;
}

您好亲爱的请使用if codition

add_shortcode( 'show_events', 'events_query' );

function events_query() {
    $args = array(
        'posts_per_page' => 4,
        'category_name' => 'events',
    );
    $events_query = new WP_Query( $args );
    if ( $events_query->have_posts() ) :
        $html_out = '<article>';
        $i=1;
        while ( $events_query->have_posts() ) :
            $events_query->the_post();
            if($i==1){
             $class = "new_class";
             $excerpt = the_excerpt(); 
             }
            $html_out .= '<div class="events-item'.$class."><div class="meta-date">' . Date('F j, Y') . '</div><div class="meta-info"><div class="meta-title"><h4><a href="' . get_permalink() . '">' . get_the_title() . '</a></h4>
            <p>'.$excerpt.'</p></div></div></div>';
            $i++;
        endwhile;
