wordpress修改默认的媒体播放器

本来几乎少有在blog上放置音乐，但是看到之前的帖子的哪个音频播放UI简直难受的很，已经记不起WP是从多少版本开始有这种协调默认的媒体播放界面。刚开始应该是使用html5的默认audio播放界面，后面就使用MediaElement.js的播放器且覆盖了样式，默认都是黑色调的蓝/白色进度条的那种。

音频播放界面如上图样子，早就该改了的 实在难受 😱 😱

，style很好看 也就照教程搬过来用了。
修改后的样式：

添加样式文件

主题目录下新建文件

/* Media Element Player styles */

/* Player background */
.mytheme-mejs-container.mejs-container,
.mytheme-mejs-container .mejs-controls,
.mytheme-mejs-container .mejs-embed,
.mytheme-mejs-container .mejs-embed body {
    background-color: #efefef;
}

/* Playmejs-time-floater controls */
.mytheme-mejs-container .mejs-button > button {
    background-image: url(images/mejs-controls-dark.svg);
}

.mytheme-mejs-container .mejs-time {
    color: #888888;
}

/* Progress and audio bars */

/* Progress and audio bar background */
.mytheme-mejs-container .mejs-controls .mejs-horizontal-volume-slider .mejs-horizontal-volume-total,
.mytheme-mejs-container .mejs-controls .mejs-time-rail .mejs-time-total {
    background-color: #fff;
}

/* Track progress bar background (amount of track fully loaded)
  We prefer to style these with the main accent color of our theme */
.mytheme-mejs-container .mejs-controls .mejs-time-rail .mejs-time-loaded {
    background-color: rgba(219, 78, 136, 0.075);
}

/* Current track progress and active audio volume level bar */
.mytheme-mejs-container .mejs-controls .mejs-horizontal-volume-slider .mejs-horizontal-volume-current,
.mytheme-mejs-container .mejs-controls .mejs-time-rail .mejs-time-current {
    background: #db4e88;
}

/* Reduce height of the progress and audio bars */
.mytheme-mejs-container .mejs-time-buffering,
.mytheme-mejs-container .mejs-time-current,
.mytheme-mejs-container .mejs-time-float,
.mytheme-mejs-container .mejs-time-float-corner,
.mytheme-mejs-container .mejs-time-float-current,

.mytheme-mejs-container .mejs-horizontal-volume-total,
.mytheme-mejs-container .mejs-time-handle-content {
    height: 3px;
}

.mytheme-mejs-container .mejs-time-handle-content {
    top: -6px;
}

.mytheme-mejs-container .mejs-time-total {
    margin-top: 8px;
}

.mytheme-mejs-container .mejs-horizontal-volume-total {
    top: 19px;
}

/* WordPress audio playlist styles */

.wp-playlist-light {
    box-shadow: 3px 3px 0 #e2e2e2;
}

/* Captions - Track titles / subtitles, time */
.wp-playlist-light .wp-playlist-caption,
.wp-playlist-light .wp-playlist-item-length {
    color: #787878;
}

/* Captions - Current track */
.wp-playlist-light .wp-playlist-current-item .wp-playlist-item-title {
    font-size: 16px;
}

.wp-playlist-light .wp-playlist-item-album {
    font-style: normal;
}

.wp-playlist-light .wp-playlist-item-artist {
    text-transform: none;
    opacity: .8;
}

/* Playlist items */
.wp-playlist-light .wp-playlist-item {
    padding: 10px 0;
    border-bottom-color: #efefef;
}

.wp-playlist-light .wp-playlist-item:last-child {
    padding-bottom: 0;
}

.wp-playlist-light .wp-playlist-playing {
    font-weight: normal;
    border-bottom-color: #db4e88;
}

.wp-playlist-light .wp-playlist-item-length {
    top: 10px;
}

/*调整优化*/
.mejs-time-float,.mejs-time-float-current,.mejs-time-float-corner{
    border:none ;
    color: #888888; /*设置文字颜色*/
}
.wp-audio-shortcode a,.wp-playlist a{
    border-bottom:none; /*去除主题的a标签全局下划线*/
}

说明：
调整优化部分是我自行添加的，主要是避免和本主题的样式冲突

添加svg播放图标

mejs-controls-dark.svg放置在主题css/images目录下

挂载脚本

functions.php适当位置添加css和js加载的钩子

//加载之前新建的my-theme-player.css文件
//判断启用wp-mediaelement才会加载  避免多余的资源请求
add_action( 'wp_footer', 'ci_theme_footer_scripts' );

function ci_theme_footer_scripts() {
    if ( wp_style_is( 'wp-mediaelement', 'enqueued' ) ) {
        wp_enqueue_style( 'my-theme-player', get_template_directory_uri() . '/css/my-theme-player.css', array(
            'wp-mediaelement',
        ), '1.0' );
    }
}

//给MediaElementJs播放器添加自定义样式mytheme-mejs-container  用于重写系统自带css
/**
 * Add an HTML class to MediaElement.js container elements to aid styling.
 *
 * Extends the core _wpmejsSettings object to add a new feature via the
 * MediaElement.js plugin API.
 */
add_action( 'wp_print_footer_scripts', 'mytheme_mejs_add_container_class' );

function mytheme_mejs_add_container_class() {
    if ( ! wp_script_is( 'mediaelement', 'done' ) ) {
        return;
    }
    ?>
    <script>
        (function() {
            var settings = window._wpmejsSettings || {};
            settings.features = settings.features || mejs.MepDefaults.features;
            settings.features.push( 'exampleclass' );
            MediaElementPlayer.prototype.buildexampleclass = function( player ) {
                player.container.addClass( 'mytheme-mejs-container' );
            };
        })();
    </script>
    <?php
}

PEACE～
