纯代码实现RiPro主题和日主题网页滚动弹幕教程

1、在主题根目录下创建server.php文件,PHP代码如下：

<?php
/*!
 *@name     server.php
 *@project  jquery.barrager.js
 *@des        RiPro弹幕插件服务端
 *@author   Ernie
*/
require_once($_SERVER['DOCUMENT_ROOT'] . '/wp-config.php');
require_once($_SERVER['DOCUMENT_ROOT'] . '/wp-includes/wp-db.php');
$list = $wpdb->get_results("SELECT * FROM $paylog_table_name WHERE status =1 ORDER BY pay_time DESC limit 10");
$mode = intval($_GET['mode']);
$barrages = array();
foreach ($list as $value) {
  $info = substr_replace(get_user_by('id', $value->user_id)->user_login, '**', '2') . " 刚刚下载了 " . mb_substr(get_the_title($value->post_id), 0, 8);
  $img = str_replace('http:', 'https:', get_user_meta($value->user_id)['user_custom_avatar'][0]);
  $href = get_permalink($value->post_id);
  $new = array(
    'info'   => $info,
    'img'   => $img,
    'href'   => $href,
    'speed'   => 15,
    'color'  =>  '#fff',
    'bottom'  => 70,
    'close'  => false
  );
  array_push($barrages, $new);
};
if ($mode === 1) {
  echo json_encode($barrages[array_rand($barrages)]);
} elseif ($mode === 2) {
  echo json_encode($barrages);
}

2、，在主题的assets/js文件夹下创建jquery.barrager.js文件，js代码如下：

(function($){$.fn.barrager=function(barrage){barrage=$.extend({close:true,bottom:0,max:10,speed:8,color:"#fff",old_ie_color:"#000000"},barrage||{});var time=new Date().getTime();var barrager_id="barrage_"+time;var id="#"+barrager_id;var div_barrager=$("<div class='barrage' id='"+barrager_id+"'></div>").appendTo($(this));var window_height=$(window).height()-100;var this_height=(window_height>this.height())?this.height():window_height;var window_width=$(window).width()+500;var this_width=(window_width>this.width())?this.width():window_width;var bottom=(barrage.bottom==0)?Math.floor(Math.random()*this_height+40):barrage.bottom;div_barrager.css("bottom",bottom+"px");div_barrager_box=$("<div class='barrage_box cl'></div>").appendTo(div_barrager);if(barrage.img){div_barrager_box.append("<a class='portrait z' href='javascript:;'></a>");var img=$("<img src='' >").appendTo(id+" .barrage_box .portrait");img.attr("src",barrage.img)}div_barrager_box.append(" <div class='z p'></div>");if(barrage.close){div_barrager_box.append(" <div class='close z'></div>")}var content=$("<a title='' href='' target='_blank' rel="noopener noreferrer"></a>").appendTo(id+" .barrage_box .p");content.attr({"href":barrage.href,"id":barrage.id}).empty().append(barrage.info);if(navigator.userAgent.indexOf("MSIE 6.0")>0||navigator.userAgent.indexOf("MSIE 7.0")>0||navigator.userAgent.indexOf("MSIE 8.0")>0){content.css("color",barrage.old_ie_color)}else{content.css("color",barrage.color)}var i=0;div_barrager.css("margin-right",0);$(id).animate({right:this_width},barrage.speed*1000,function(){$(id).remove()});div_barrager_box.mouseover(function(){$(id).stop(true)});div_barrager_box.mouseout(function(){$(id).animate({right:this_width},barrage.speed*1000,function(){$(id).remove()})});$(id+".barrage .barrage_box .close").click(function(){$(id).remove()})};$.fn.barrager.removeAll=function(){$(".barrage").remove()}})(jQuery);$.ajaxSettings.async=false;$.getJSON("https://你的域名/wp-content/themes/ripro/server.php?mode=2",function(data){var looper_time=5000;var items=data;var total=data.length;var run_once=true;var index=0;barrager();function barrager(){if(run_once){looper=setInterval(barrager,looper_time);run_once=false}$("body").barrager(items[index]);index++;if(index==total){clearInterval(looper);return false}}});

3、修改主题的header.php文件，引用刚刚创建的js文件，插入代码：

<script type='text/javascript' src='https://你的域名/wp-content/themes/ripro/assets/js/jquery.barrager.js'></script>

4、在主题assets/css/diy.css文件里插入样式代码：

.barrage{position: fixed;bottom:70px;right:-500px;display: inline-block;width: 500px;z-index: 99999}
.barrage_box{background-color: rgba(0,0,0,.5);padding-right: 8px; height: 40px;display: inline-block;border-radius: 25px;transition: all .3s;}
.barrage_box .portrait{ display: inline-block;margin-top: 4px; margin-left: 4px; width: 32px;height: 32px;border-radius: 50%;overflow: hidden;}
.barrage_box .portrait img{width: 100%;height: 100%;}
.barrage_box div.p a{ margin-right: 2px; font-size: 14px;color: #fff;line-height: 40px;margin-left: 18px; }
.barrage_box div.p a:hover{text-decoration: underline;}
.barrage_box .close{visibility: hidden;opacity: 0; text-align: center; width:25px;height: 25px;margin-left: 20px;border-radius: 50%;background:rgba(255,255,255,.1);margin-top:8px; background-image: url(close.png);}
.barrage_box:hover .close{visibility:visible;opacity: 1;}
.barrage_box .close a{display:block;}
.barrage_box .close .icon-close{font-size: 14px;color:rgba(255,255,255,.5);display: inline-block;margin-top: 5px; }
.barrage .z {float: left !important;}
.barrage  a{text-decoration:none;}
