B2主题给网站首页增加一个公告模块(快讯滚动模块修改)
原教程来自哔哔鸡
B2小工具的【用户面板】其实是有公告的,但是我首页没有开通这个小工具。有个需求就是想要将公告栏放在首页banner的下面。
逛圈子的时候,发现哔哔鸡给开发了一个快讯滚动模块,这刚好就是我需要的。
原版本的教程,是滚动快讯。需要应用layui文件,我直接将其改为了不滚动,信息展示为公告。
我会在结尾放上原版的代码,如果需要原版可以自取。

我修改后的演示
直接首页看就行了。注意:上面的原版演示图是哔哔鸡开发的最新版,增加了一个发表快报按钮和手机端自适应。
我首页的是之前老版本进行修改的。
教程
进入网站后台-B2主题设置-首页。添加一个公告模块。当然也可以是其他的,商铺、快讯、供求这些都可以。我们主要是用这个样式。

<div class="indexbibi"><span class="indexbibi-box"><a title="所有公告" href="/announcement" target="_blank" class="indexbibi-title"><spanstyle="font-size: 15px;color: #fff;font-weight: 600;text-shadow: 0px 0px 2px rgb(0 0 0 / 25%);">最新公告</span><sup class="index-yuandian index-yuandian-sm ml-1 small" role="status" aria-hidden="true"style="margin-top: 2px;margin-right: 1px;margin-left: 1px;width: .5rem;height: .5rem;"></sup></a><span class="indexbibi-content"><div class="layui-carousel" id="index-bibirj"><div carousel-item><?php$args = array('post_type' => 'announcement','posts_per_page' => 1,);$posts_query = new WP_Query($args);if ($posts_query->have_posts()) {while ($posts_query->have_posts()) {$posts_query->the_post();?><div class="bibi-div"><span class="bibi-span"><a title="查看详细" class="bibi-a" target="_blank" href="<?php the_permalink(); ?>"><span style="color: #aac6d9; margin: 0 7px 0 7px;">|</span><span class="bibi-title"><?php the_title(); ?></span></a><span class="bibi-tag"><?php$tags = get_the_terms(get_the_ID(), 'newsflashes_tags');if ($tags && !is_wp_error($tags)) {foreach ($tags as $tag) {echo '<a target="_blank" href="' . get_term_link($tag) . '">' . $tag->name . '</a>';echo ' ';}}?></span></span></div><?php}wp_reset_postdata();} else {echo "嗯?最近好像没最新的公告。";}?></div></div><!-- 条目中可以是任意内容,如:<img src=""> --></span><span class="indexbibi-num"><span><?php$today = getdate(); // 获取当前日期$args = array('post_type' => 'post','post_status' => 'publish','cat' => 'your_category_id', // 替换为您的分类 ID'date_query' => array(array('year' => $today['year'],'month' => $today['mon'],'day' => $today['mday'],),),);$query = new WP_Query($args);$count = $query->found_posts;?>今日文章:<span><?php echo $count; ?></span> 篇</span><span><?php$args = array('post_type' => 'announcement','post_status' => 'publish','posts_per_page' => -1,'fields' => 'ids');$query = new WP_Query($args);$count = $query->found_posts;?>公告总数:<span><?php echo $count; ?></span> 篇</span></span></span></div>
此模块是有短代码的,简而言之,我们可以把这个公告模块,放在任何地方。
这里注意一下。
'post_type' => 'announcement',
就是文章类型为公告,如果你想改成其他的如快讯newsflashes、商品shop、圈子circle、供求infomation等等都可以根据自己的需求更换。
CSS样式
我将CSS放在了子主题中,themes/b2child/style.css ,这样下次更新主题就不会被覆盖了。

保存后,即可在首页看到你的公告栏目。
原版的我就不在这里贴代码了,样式代码有点多。自己去下面下载哈。
