最新WordPress网站B2主题美化之文章彩色角标

2.B2主题实现教程

①.打开B2主题文件：/b2/Modules/Settings/Post.php  464 在$gg_meta = new_cmb2_box 之前添加：处加入以下代码：

// 文章添加角标开始-https://www.uwwuww.com
    $post_meta = new_cmb2_box(array(
    'id' => 'b2_post_onecad_jb',
    'title' => __( '文章角标', 'b2' ),
    'object_types' => array('post','document','page'),
    'context' => 'normal',
    'priority' => 'high',
    'show_names' => true
    ));
    $post_meta->add_field(array(
    $g_name = b2_get_option('normal_custom','custom_announcement_name'),
    'name' => sprintf(__('列表需要显示角标','b2'),$g_name),
    'id' => 'b2_post_onecad_lb',
    'type' => 'select',
    'options'=>array(
    0=>__('推荐','b2'),
    1=>__('VIP','b2'),
    2=>__('原创','b2'),
    3=>__('免费','b2')
    ),
    'default'=>0,
    'desc'=> __('支持 HTML，尽量短小才好看。','b2')
    ));
    add_filter('post_side_settings', 'wporg_custom');
    // 文章添加角标结束-https://www.uwwuww.com

②.刷新缓存，在后台文章写作页面，即可看到角标设置项

③.在文章样式列表文件中b2/Modules/Templates/Modules/Posts.php 在第一个$hove_avatar前添加以下代码：第108行下方增加：

$b2_post_onecad_lb= get_post_meta($v['id'],'b2_post_onecad_lb',true);
if($b2_post_onecad_lb == ''){
$meta_jiaobiao_html ='<span>'.$b2_post_onecad_lb.'</span>';
}else if($b2_post_onecad_lb ==0){
$meta_jiaobiao_html ='<span class="tipss huodong b2-radius">推荐</span>';
}else if($b2_post_onecad_lb ==1){
$meta_jiaobiao_html = '<span class="tipss remen b2-radius">VIP</span>';
}else if($b2_post_onecad_lb ==2){
$meta_jiaobiao_html ='<span class="tipss jingping b2-radius">原创</span>';
}else if($b2_post_onecad_lb ==3){
$meta_jiaobiao_html ='<span class="tipss tuijain b2-radius">免费</span>';
}

④.然后再同文件的第168行下方增加调用

'.$meta_jiaobiao_html.'

⑤下面就是CSS了，将下方的CSS代码复制到子主题style.css文件中即可

/*角标CSS-https://www.uwwuww.com*/

    position: absolute;
    top: 10px;
    left: 10px;
    z-index: 1;
    width: 50px;

    z-index: 100;
    }
    .yellow {background-color: #ff6000;}
