WordPress教程:置顶文章显示在分类/标签等存档页的最上方
WordPress自带的文章置顶功能,只支持在首页让置顶文章在顶部显示,在分类、标签、作者和日期等存档页面,就没法让置顶文章在顶部显示了,只能按默认的顺序显示。在使用的过程中,很多时候,我们需要把置顶文章显示在这些存档页面的顶部。 这篇WordPress教程里,我们参考 wp-includes/query.php 中首页置顶的代码,稍做修改,向大家讲解一下存档页面的顶部显示置顶文章的方法。 切换到主题目录,打开functions.php文件,添加如下代码: query_vars['paged'] <= 1 && !empty($sticky_posts) && is_array($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置顶文章
$offset1 = array_search($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,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,array( $sticky_post ) );
$sticky_offset++;
}
}
}
return $posts;
