Wordpress - 分页不适用于自定义循环，但在博客页面中工作

Question

I have a loop with custom post types, and pagination doesn't appear, when I enter the URL with /page/2, /page/3... it shows the content correctly, but links don't appear on the page.

Here is the code:

<?php 
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$parent_only_query = new WP_Query(array(
    'post_type' => 'my_cpt',
    'posts_per_page' => 4,
    'paged' => $paged,
    'post_parent' => 0 
));

while ($parent_only_query->have_posts()){
    $parent_only_query->the_post();

//content

}       
pagination(); ?>

Archive page with pagination working:

<?php /* Start the Loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>

<?php //content ?>

<?php endwhile; ?>

<?php else : ?>

<?php get_template_part( 'loop-templates/content', 'none' ); ?>

<?php endif; ?>
<?php pagination(); ?>

Answer 1

 add this in your functions.php function pagination_nav() { global $wp_query; if ( $wp_query->max_num_pages > 1 ) { ?> <nav class="pagination" role="navigation"> <div class="nav-previous"><?php next_posts_link( '&larr; Older posts' ); ?></div> <div class="nav-next"><?php previous_posts_link( 'Newer posts &rarr;' ); ?></div> </nav> <?php } } display on page.php <?php pagination_nav(); ?> 

Answer 2

pagination can be shown in custom post type archive template and on custom template as well.

Pagination for archive template.

    // current page
   $paged = get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1;


    // prepare arguments
   $args = array( 'post_type' => 'product',
    'post_type' => 'my_cpt',
    'posts_per_page' => 4,
    'paged' => $paged,
    'post_parent' => 0 
   );


    //prepare query
    new WP_Query( $args ); 

        // Call pagination function before wp_reset_postdata()
        the_posts_pagination( array(
            'prev_text'          => '<span class="fa fa-angle-left" aria-hidden="true"></span>',
            'next_text'          => '<span class="fa fa-angle-right" aria-hidden="true"></span>',
            'screen_reader_text' => '&nbsp;',
            'before_page_number' => '',
            'mid_size'    => 3,
        ) );

Pagination for custom Template

    // Get current page.
    $paged = get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1;


    // prepare arguments
    $args = array( 
     post_type' => 'my_cpt',
     'posts_per_page' => 4,
     'paged' => $paged,
     'post_parent' => 0 
   );


    //prepare query
    $query = new WP_Query( $args );
    $totalPage=$query->max_num_pages;



    $big = 999999999; // need an unlikely integer
    echo paginate_links( array(
         'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
         'format' => '?paged=%#%',
         'current' => max( 1, get_query_var('paged') ),
         'total' => $totalPage
     ) );
