在wordpress中默认能置顶文章就是只有首页了,如果我们希望分类/标签等存档页也能置顶文章我们需要二次开发.
现在参考wp-includes/query.php中首页置顶的代码,稍微修改一下,可以让分类页、标签页、作者页和日期页等存档页面也能像首页一样在顶部显示其范围内的置顶文章,把下面的代码放到当前主题下的functions.php中就可以了.
代码如下:
add_filter('the_posts','putStickyOnTop');functionputStickyOnTop($posts){if(is_home()||!is_main_query()||!is_archive())return$posts;global$wp_query;$sticky_posts=get_option('sticky_posts');if($wp_query->query_vars['paged']<=1&&is_array($sticky_posts)&&!emptyempty($sticky_posts)&&!get_query_var('ignore_sticky_posts')){$stickies1=get_posts(array('post__in'=>$sticky_posts));foreach($stickies1as$sticky_post1){//判断当前是否分类页if($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;//Loopoverpostsandrelocatestickiestothefront.for($i=0;$i<$num_posts;$i++){if(in_array($posts[$i]->ID,$sticky_posts)){$sticky_post=$posts[$i];//Removestickyfromcurrentpositionarray_splice($posts,$i,1);//Movetofront,afterotherstickiesarray_splice($posts,$sticky_offset,0,array($sticky_post));//Incrementthestickyoffset.Thenextstickywillbeplacedatthisoffset.$sticky_offset++;//Removepostfromstickypostsarray$offset=array_search($sticky_post->ID,$sticky_posts);unset($sticky_posts[$offset]);}}//Ifanypostshavebeenexcludedspecifically,Ignorethosethataresticky.if(!emptyempty($sticky_posts)&&!emptyempty($wp_query->query_vars['post__not_in']))$sticky_posts=array_diff($sticky_posts,$wp_query->query_vars['post__not_in']);//Fetchstickypoststhatweren'tinthequeryresultsif(!emptyempty($sticky_posts)){$stickies=get_posts(array('post__in'=>$sticky_posts,'post_type'=>$wp_query->query_vars['post_type'],'post_status'=>'publish','nopaging'=>true));foreach($stickiesas$sticky_post){array_splice($posts,$sticky_offset,0,array($sticky_post));$sticky_offset++;}}}return$posts;}
