WordPress自定义分页未显示在自定义帖子类型上

Question

当我在自定义帖子类型循环中调用该函数时，我的自定义分页函数没有返回任何值，我不知道为什么。

我的分页功能适用于主页，但不适用于自定义帖子类型，我也将它用于我的 WooCommerce 分页，它在那里工作正常。

这是我的循环：

<?php
  $args = array(
    'post_type'=>'winners',
    'posts_per_page' => 6,
    'paged' => get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1,
  );
  $loop = new WP_Query( $args );
  if ( $loop->have_posts() ) {
    while ( $loop->have_posts() ) : $loop->the_post();
  ?>
    <?php the_title(); ?>
  <?php
    endwhile;
    topdraw_pagination();
  }
  wp_reset_postdata();
  ?>

这是我的分页功能：

<?php
function topdraw_pagination() {
    if( is_singular() ) {
        return;
    }
    global $wp_query;
    if( $wp_query->max_num_pages <= 1 ) {
        return;
    }
    $paged = get_query_var( 'paged' ) ? absint( get_query_var( 'paged' ) ) : 1;
    $max = intval( $wp_query->max_num_pages );
    if( $paged >= 1 ) {
        $links[] = $paged;
    }
    if( $paged >= 3 ) {
        $links[] = $paged - 1;
    }
    if( ( $paged + 2 ) <= $max ) {
        $links[] = $paged + 1;
    }
    echo '<nav class="pagination">' . "\n";
    if ( get_previous_posts_link() ) {
        printf( '%s' . "\n", get_previous_posts_link('<span class="icon is-small"><i class="fas fa-caret-left"></i></span>') );
    }
    if ( get_next_posts_link() ) {
        printf( '%s' . "\n", get_next_posts_link('<span class="icon is-small"><i class="fas fa-caret-right"></i></span>') );
    }
    echo '<ul class="pagination-list">' . "\n";
    if( ! in_array( 1, $links ) ) {
        $class = 1 == $paged ? ' is-current' : '';
        $aria_current = 1 == $paged ? ' aria-current="page"' : '';
        printf( '<li><a href="%s" class="pagination-link%s" aria-label="Goto page 1"%s>%s</a></li>' . "\n", esc_url( get_pagenum_link( 1 ) ), $class, $aria_current, '1' );
        if ( ! in_array( 2, $links ) ) {
            echo '<li><span class="pagination-ellipsis">&hellip;</span></li>' . "\n";
        }
    }
    sort( $links );
    foreach ( (array) $links as $link ) {
        $class = $paged == $link ? ' is-current' : '';
        $aria_current = $paged == $link ? ' aria-current="page"' : '';
        printf( '<li><a href="%s" class="pagination-link%s" aria-label="Goto page %s"%s>%s</a></li>' . "\n", esc_url( get_pagenum_link( $link ) ), $class, $link, $aria_current, $link );
    }
    if ( ! in_array( $max, $links ) ) {
        if ( ! in_array( $max - 1, $links ) ) {
            echo '<li><span class="pagination-ellipsis">&hellip;</span></li>' . "\n";
        }
        $class = $paged == $max ? ' is-current' : '';
        $aria_current = $paged == $max ? ' aria-current="page"' : '';
        printf( '<li><a href="%s" class="pagination-link%s" aria-label="Goto page %s"%s>%s</a></li>' . "\n", esc_url( get_pagenum_link( $max ) ), $class, $max, $aria_current, $max );
    }
    echo '</ul></nav>' . "\n";
}

add_filter( 'next_posts_link_attributes', 'topdraw_next_posts_link_class' );
add_filter( 'previous_posts_link_attributes', 'topdraw_previous_posts_link_class' );

function topdraw_next_posts_link_class() {
    return 'class="pagination-next"';
}

function topdraw_previous_posts_link_class() {
    return 'class="pagination-previous"';
}

提前感谢您的帮助。

Answer 1

我通过在自定义帖子类型循环中将 $loop 重命名为 $wp_query 来解决此问题。如果有人能解释为什么这能解决问题，我将不胜感激。

Answer 2

您需要将自定义 WP_Query 实例传递给分页函数，而不是使用全局 $wp_query

  $args = array(
   'post_type'=>'winners',
   'posts_per_page' => 6,
   'paged' => get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1,
  );
  $loop = new WP_Query( $args );
  if ( $loop->have_posts() ) {

   while ( $loop->have_posts() ) : $loop->the_post();
     the_title(); ?>
   endwhile;

   topdraw_pagination( $loop );
  }
  wp_reset_postdata();

还有你的功能：

function topdraw_pagination( $loop ) {

 if( is_singular() ) {
    return;
 }

 if( $loop->max_num_pages <= 1 ) {
    return;
 }

 $paged = get_query_var( 'paged' ) ? absint( get_query_var( 'paged' ) ) : 1;
 $max = intval( $loop->max_num_pages );
 if( $paged >= 1 ) {
    $links[] = $paged;
 }
 if( $paged >= 3 ) {
    $links[] = $paged - 1;
 }
 if( ( $paged + 2 ) <= $max ) {
    $links[] = $paged + 1;
 }
 echo '<nav class="pagination">' . "\n";
 if ( get_previous_posts_link() ) {
    printf( '%s' . "\n", get_previous_posts_link('<span class="icon is-small"><i class="fas fa-caret-left"></i></span>') );
 }
 if ( get_next_posts_link() ) {
    printf( '%s' . "\n", get_next_posts_link('<span class="icon is-small"><i class="fas fa-caret-right"></i></span>') );
 }
 echo '<ul class="pagination-list">' . "\n";
 if( ! in_array( 1, $links ) ) {
    $class = 1 == $paged ? ' is-current' : '';
    $aria_current = 1 == $paged ? ' aria-current="page"' : '';
    printf( '<li><a href="%s" class="pagination-link%s" aria-label="Goto page 1"%s>%s</a></li>' . "\n", esc_url( get_pagenum_link( 1 ) ), $class, $aria_current, '1' );
    if ( ! in_array( 2, $links ) ) {
        echo '<li><span class="pagination-ellipsis">&hellip;</span></li>' . "\n";
    }
 }
 sort( $links );
 foreach ( (array) $links as $link ) {
    $class = $paged == $link ? ' is-current' : '';
    $aria_current = $paged == $link ? ' aria-current="page"' : '';
    printf( '<li><a href="%s" class="pagination-link%s" aria-label="Goto page %s"%s>%s</a></li>' . "\n", esc_url( get_pagenum_link( $link ) ), $class, $link, $aria_current, $link );
 }
 if ( ! in_array( $max, $links ) ) {
    if ( ! in_array( $max - 1, $links ) ) {
        echo '<li><span class="pagination-ellipsis">&hellip;</span></li>' . "\n";
    }
    $class = $paged == $max ? ' is-current' : '';
    $aria_current = $paged == $max ? ' aria-current="page"' : '';
    printf( '<li><a href="%s" class="pagination-link%s" aria-label="Goto page %s"%s>%s</a></li>' . "\n", esc_url( get_pagenum_link( $max ) ), $class, $max, $aria_current, $max );
 }
 echo '</ul></nav>' . "\n";
}
