wordpress分类文章置顶首页不要置顶

昨晚做本博客的工作日志，分类置顶文章，我想要的效果是在分类下文章是置顶的，但是首页却不要置顶，我在网上找到了分类文章置顶，但是都没解决首页文章不置顶的问题，都说说改首页sticky。所以我就想到了一个办法，第一步用这个分类置顶，第二步，让首页不显示置顶文章，就这样解决了。目前只是占时需要，并不需要多么强大的功能，所以就这样勉强用着。

第一步

将下面的代码添加到主题的 functions.php 文件即可：

add_filter('the_posts',  'putStickyOnTop' );
function putStickyOnTop( $posts ) {
  if(is_home() || !is_main_query() || !is_archive())
    return $posts;
 
  global $wp_query;
 
  $sticky_posts = get_option('sticky_posts');
 
  if ( $wp_query->query_vars['paged'] <= 1 && is_array($sticky_posts) && !empty($sticky_posts) && !get_query_var('ignore_sticky_posts') ) {        $stickies1 = get_posts( array( 'post__in' => $sticky_posts ) );
    foreach ( $stickies1 as $sticky_post1 ) {
      // 判断当前是否分类页 
      if($wp_query->is_category == 1 && !has_category($wp_query->query_vars['cat'], $sticky_post1->ID)) {
        // 去除不属于本分类的文章
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);
        unset( $sticky_posts[$offset1] );
      }
      if($wp_query->is_tag == 1 && has_tag($wp_query->query_vars['tag'], $sticky_post1->ID)) {
        // 去除不属于本标签的文章
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);
        unset( $sticky_posts[$offset1] );
      }
      if($wp_query->is_year == 1 && date_i18n('Y', strtotime($sticky_post1->post_date))!=$wp_query->query['m']) {
        // 去除不属于本年份的文章
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);
        unset( $sticky_posts[$offset1] );
      }
      if($wp_query->is_month == 1 && date_i18n('Ym', strtotime($sticky_post1->post_date))!=$wp_query->query['m']) {
        // 去除不属于本月份的文章
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);
        unset( $sticky_posts[$offset1] );
      }
      if($wp_query->is_day == 1 && date_i18n('Ymd', strtotime($sticky_post1->post_date))!=$wp_query->query['m']) {
        // 去除不属于本日期的文章
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);
        unset( $sticky_posts[$offset1] );
      }
      if($wp_query->is_author == 1 && $sticky_post1->post_author != $wp_query->query_vars['author']) {
        // 去除不属于本作者的文章
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);
        unset( $sticky_posts[$offset1] );
      }
    }
 
    $num_posts = count($posts);
    $sticky_offset = 0;
    // Loop over posts and relocate stickies to the front.
    for ( $i = 0; $i < $num_posts; $i++ ) {
      if ( in_array($posts[$i]->ID, $sticky_posts) ) {
        $sticky_post = $posts[$i];
        // Remove sticky from current position
        array_splice($posts, $i, 1);
        // Move to front, after other stickies
        array_splice($posts, $sticky_offset, 0, array($sticky_post));
        // Increment the sticky offset. The next sticky will be placed at this offset.
        $sticky_offset++;
        // Remove post from sticky posts array
        $offset = array_search($sticky_post->ID, $sticky_posts);
        unset( $sticky_posts[$offset] );
      }
    }
 
    // If any posts have been excluded specifically, Ignore those that are sticky.
    if ( !empty($sticky_posts) && !empty($wp_query->query_vars['post__not_in'] ) )
      $sticky_posts = array_diff($sticky_posts, $wp_query->query_vars['post__not_in']);
 
    // Fetch sticky posts that weren't in the query results
    if ( !empty($sticky_posts) ) {
      $stickies = get_posts( array(
        'post__in' => $sticky_posts,
        'post_type' => $wp_query->query_vars['post_type'],
        'post_status' => 'publish',
        'nopaging' => true
      ) );
 
      foreach ( $stickies as $sticky_post ) {
        array_splice( $posts, $sticky_offset, 0, array( $sticky_post ) );
        $sticky_offset++;
      }
    }
  }
 
  return $posts;
}
