自定义WP-Query，显示“内容”页面中的所有帖子

Question

I have a custom post type "event" with a date as custom post_meta . Using the template's built-in loop would be fine but I needed to sort by date, I created a custom query:

<?php // the query
    $args = array(
        'post_type'         => 'event' ,
        'orderby'           => 'meta_value',
        'meta_query'        => array(
            array(
                'key'       => 'event_start_date',
                'type'      => 'DATE'
            )
        ),
        'posts_per_page'    =>  20, 
        'order'             =>  'DESC'
        );

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

        <!-- the loop -->
        <?php while ( $wpb_all_query->have_posts() ) : $wpb_all_query->the_post(); ?>

            <?php get_template_part( 'loop-templates/content', 'event' ); ?>

            <?php the_post_navigation( array(
                'prev_text'                  => __( '<span class="nav-prev">Prev article: %title</span>' ),
                'next_text'                  => __( '<span class="nav-next">Next article: %title</span>' ),
                'in_same_term'               => true,
                'taxonomy'                   => __( 'category' ),
                'screen_reader_text' => __( 'Continue Reading' ),
            ) ); ?>

            <?php
            // If comments are open or we have at least one comment, load up the comment template
            if ( comments_open() || get_comments_number() ) :
                comments_template();
            endif;
            ?>

        <?php endwhile; // end of the loop. ?>

The problem I have is that while the "archive" page is now sorting by date, as expected, when I go to the single page by clicking one of the post's permalink, it shows the wrong post content and then other posts below it. It's as if it's executing the query in the content template.

Does anyone have any ideas?

Answer 1

You can use different query arguments for pages. Try to use conditional tags https://codex.wordpress.org/Conditional_Tags#Single_Post

I think you need to call wp_reset_postdata() after your custom query to reset various global post variables.

In your case, you'd add <?php wp_reset_postdata(); ?> <?php wp_reset_postdata(); ?> immediately after your custom loop (ie after the endwhile statement).
