当今是个信息共享的时代，好的东西就要拿出来与大家分享，才能体现它的价值。今天我要分享的是如何在WordPress首页展示四分栏文章列表样式，效果如下图所示。
第一步：将下列代码另存为rand-hot-comment.php。
<?php
//按时间获得浏览器最高的文章
function post_viewed_tab($mode = '', $limit ='', $days = '', $display = true) {
global $wpdb, $post;
$today = date("Y-m-d H:i:s"); //获取今天日期时间
$daysago = date( "Y-m-d H:i:s", strtotime($today) - ($days * 24 * 60 * 60) ); //Today - $days
$where = '';
$temp = '';
if(!empty($mode) && $mode != 'both') {
$where = "post_type = '$mode'";
} else {
$where = '1=1';
}
$most_viewed = $wpdb->get_results("SELECT $wpdb->posts.*, (meta_value+0) AS views FROM $wpdb->posts LEFT JOIN $wpdb->postmeta ON $wpdb->postmeta.post_id = $wpdb->posts.ID WHERE post_date < '$today' AND post_date > '$daysago' AND $where AND post_status = 'publish' AND meta_key = 'views' AND post_password = '' ORDER BY views DESC LIMIT $limit");
if($most_viewed) {
foreach ($most_viewed as $post) {
$post_views = intval($post->views);
$post_views = number_format($post_views);
$temp .= "<li class=\"list-title\"><span class=\"tab-icon\"></span><a href=\"".get_permalink()."\" title=\"".get_the_title()."\" target=\"_blank\" rel="noopener noreferrer">".get_the_title()."</a></li>";
}
} else {
$temp = '<a>'.__('N/A', 'Nana').'</a>'."\n";
}
if($display) {
echo $temp;
} else {
return $temp;
}
}
?>
<?php
//按时间获得评论数最多的文章
function hot_comment_viewed_tab($number, $days){
global $wpdb, $post;
$today = date("Y-m-d H:i:s"); //获取今天日期时间
$daysago = date( "Y-m-d H:i:s", strtotime($today) - ($days * 24 * 60 * 60) ); //Today - $days
$sql = "SELECT * FROM $wpdb->posts WHERE post_type = 'post' AND post_status = 'publish' AND post_date < '$today' AND post_date > '$daysago' AND post_password = '' ORDER BY comment_count DESC LIMIT 0 , $number ";
$posts = $wpdb->get_results($sql);
$output = "";
if(empty($posts)) {
$output = '<li>None data.</li>';
} else {
foreach ($posts as $post){
$commentcount = $post->comment_count;
if ($commentcount != 0) {
$output .= "<li class=\"list-title\"><span class=\"tab-icon\"></span><a href=\"".get_permalink()."\" title=\"".get_the_title()."\" target=\"_blank\" rel="noopener noreferrer">".get_the_title()."</a></li>";
}
}
}
echo $output;
}
?>
<div class="tab-site wow fadeInUp sort" data-wow-delay="0.3s">
<div id="layout-tab" class="tab-product">
<h2 class="tab-hd">
<span class="tab-hd-con"><a href="javascript:">站长推荐</a></span>
<span class="tab-hd-con"><a href="javascript:">热门文章</a></span>
<span class="tab-hd-con"><a href="javascript:">热评文章</a></span>
<span class="tab-hd-con"><a href="javascript:">随机推荐</a></span>
</h2>
<div class="tab-bd dom-display">
<ul class="tab-bd-con current">
<?php query_posts( array ( 'meta_key' => 'hot', 'meta_value' => 'true','showposts' => 8, 'orderby' => 'rand', 'ignore_sticky_posts' => 1 ) ); while ( have_posts() ) : the_post(); ?>
<li class="list-title"><span class="tab-icon"></span><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>" target="_blank"><?php the_title(); ?></a>
</li>
<?php endwhile;wp_reset_query();?>
</ul>
<ul class="tab-bd-con">
<?php post_viewed_tab('post',8,90, true, true);wp_reset_query(); ?>
</ul>
<ul class="tab-bd-con">
<?php hot_comment_viewed_tab(8, 90);wp_reset_query(); ?>
</ul>
<ul class="tab-bd-con">
<?php $args = array('numberposts' => 8, 'orderby' => 'rand',);$rand_posts = get_posts($args); foreach( $rand_posts as $post ): ?>
<li class="list-title"><span class="tab-icon"></span><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; wp_reset_query(); ?>
</ul>
</div>
</div>
</div>
<div class="clear"></div>
第二步：将rand-hot-comment.php上传到主题inc文件夹内，并在需要显示的位置插入下列代码。
get_template_part( '/inc/rand-hot-comment' );
第三步：将下列css代码，加入到主题style样式中。
.tab-site {overflow: hidden;margin: 0 0 10px 0;border: 1px solid #ddd;border-radius:0px;box-shadow: 0 1px 1px rgba(0, 0, 0, 0.04);}
.tab-hd {overflow: hidden;height: 40px;line-height: 40px;}
.tab-hd-con {float: left;text-align: center;cursor: pointer;height: 39px;border-right: 1px solid #ddd;font-size: 1pc;}
.tab-hd-con {width: 25%;}
.dom-display .current {display: block;}
.tab-hd .current{border-bottom: 3px solid #c01e22;}
.tab-hd .current a{color:#c01e22;}
.tab-bd-con {display: none; overflow: hidden;}
.tab-bd li {float: left;width: 47.35%;line-height: 210%;margin: 0 20px 0 0;white-space: nowrap; word-wrap: normal;text-overflow: ellipsis;overflow: hidden;}
@media screen and (max-width: 480px) {.tab-bd li {width: 95%;margin: 0 0 0 0;}}
.list-title {width: 84%;line-height: 210%; white-space: nowrap;word-wrap: normal;text-overflow: ellipsis; overflow: hidden;}
.tab-site {overflow:hidden;background:#fff;padding-bottom:10px}
.tab-bd li a{color:#555;}
.tab-bd .list-title .tab-icon:before{content:'\f105'}
.tab-bd .list-title .tab-icon{font-family:fontawesome; margin-right:5px;}
.tab-bd li a:hover{color:#c01e22;text-decoration:underline}
.tab-bd {background: #fff; padding:10px 15px;margin-top:-1px; border-top: 1px solid #ddd;}
第四步：将下列代码加到主题的script.js里。
$(document).ready(function(){
$("#layout-tab span:first").addClass("current");
$("#layout-tab .tab-bd-con:gt(0)").hide();
$("#layout-tab span").mouseover(function(){
$(this).addClass("current").siblings("span").removeClass("current");
$("#layout-tab .tab-bd-con:eq("+$(this).index()+")").show().siblings(".tab-bd-con").hide().addClass("current");
});
});
好了，方法就介绍完成了，大致方法如上所示，可能不能完全适应其它主题，需自行修改。
修改后，按照天数自动对有评论的文章进行排序。
只需要将主题下inc/functions下的hot-comment.php中的第5-11行代码
修改后，如下图，在后台设置期限，可以正常显示。
