Question

我创建了一个帖子以显示书籍列表。我添加了一个计数器来显示这本书的排名。

这是分页的帖子，每页10个帖子。当我转到下一页时，计数器不断返回原始编号。

例如：

Page 1  - 100, 99, ... 91
Page 2  - 100, 99, ... 91
...
Page 10 - 100, 99, ... 91

我希望计数器正常运行，显示 100-1 。

这是我正在使用的代码：

<?php
$postidsstring = get_field('post_ids_to_be_included');
$postidsarray = explode(", ",$postidsstring);
$countposts = count($postidsarray);
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
    'post_type'      => 'books',
    'post__in'       => $postidsarray,
    'orderby'        => 'post__in',
    'numberposts'    => -1,
    'paged'          => $paged,
    'posts_per_page' => 10
);
$myposts = new WP_Query( $args );
$total_pages = $myposts->max_num_pages;
if ( $myposts->have_posts() ) :
    while ( $myposts->have_posts() ) : $myposts->the_post(); ?>
        <?php echo $countposts; ?>. <?php the_title(); $countposts--; ?>
        //Other details
        <br>
    <?php endwhile;
    if ($total_pages > 1) :
        $current_page = max(1, get_query_var('paged'));
        echo paginate_links(array(
            'base'     => get_pagenum_link(1) . '%_%',
            'format'   => '/page/%#%',
            'current'  => $current_page,
            'total'    => $total_pages,
            'prev_text'=> __('« prev'),
            'next_text'=> __('next »'),
        ));
    endif;
endif;
wp_reset_postdata(); 
?>

如何纠正此问题？

编辑：我正在使用此代码来防止重定向到function.php中的页面1：

add_action( 'template_redirect', function() {
    if ( is_singular( 'list' ) ) {
        global $wp_query;
        $page = ( int ) $wp_query->get( 'page' );
        if ( $page > 1 ) {
            // convert 'page' to 'paged'
            $query->set( 'page', 1 );
            $query->set( 'paged', $page );
        }
        // prevent redirect
        remove_action( 'template_redirect', 'redirect_canonical' );
    }
}, 0 );

我找到了一个解决方案，尽管不确定它是否正确，但这对我有用。我添加了另一个计数器，该计数器将使用变量countposts，current_page和posts_per_page中的值来显示正确的计数器。就是这样：

<?php
$postidsstring = get_field('post_ids_to_be_included');
$postidsarray = explode(", ",$postidsstring);
$countposts = count($postidsarray);
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
    'post_type'      => 'books',
    'post__in'       => $postidsarray,
    'orderby'        => 'post__in',
    'numberposts'    => -1,
    'paged'          => $paged,
    'posts_per_page' => 10
);
$myposts = new WP_Query( $args );
$total_pages = $myposts->max_num_pages;
if ( $myposts->have_posts() ) :
    $current_page = max(1, get_query_var('paged'));
    while ( $myposts->have_posts() ) : $myposts->the_post(); 
        $counter = $countposts-(($current_page-1)*$posts_per_page); ?>
        <?php echo $counter; ?>. <?php the_title(); $countposts--; ?>
        //Other details
        <br>
    <?php endwhile;
    if ($total_pages > 1) :
        $current_page = max(1, get_query_var('paged'));
        echo paginate_links(array(
            'base'     => get_pagenum_link(1) . '%_%',
            'format'   => '/page/%#%',
            'current'  => $current_page,
            'total'    => $total_pages,
            'prev_text'=> __('« prev'),
            'next_text'=> __('next »'),
        ));
    endif;
endif;
wp_reset_postdata(); 
?>

我从旧的blog post获得了此解决方案。
