WordPress 后台编辑器上传视频的时候是以video短代码返回到内容里的,这样子有些小程序没法识别,所以需要把短代码改成video标签。
将以下代码加入到主题的functions.php里:
remove_shortcode( 'video', 'wp_video_shortcode' );add_shortcode( 'video', 'MBT_video_shortcode' );function MBT_video_shortcode( $attr, $content = '' ) {global $content_width;$post_id = get_post() ? get_the_ID() : 0;static $instance = 0;$instance++;$override = apply_filters( 'wp_video_shortcode_override', '', $attr, $content, $instance );if ( '' !== $override ) {return $override;}$video = null;$default_types = wp_get_video_extensions();$defaults_atts = array('src' => '','poster' => '','loop' => '','autoplay' => '','preload' => 'metadata','width' => 640,'height' => 360,//'class' => 'wp-video-shortcode',);foreach ( $default_types as $type ) {$defaults_atts[$type] = '';}$atts = shortcode_atts( $defaults_atts, $attr, 'video' );if ( is_admin() ) {if ( $atts['width'] > $defaults_atts['width'] ) {$atts['height'] = round( ( $atts['height'] * $defaults_atts['width'] ) / $atts['width'] );$atts['width'] = $defaults_atts['width'];}} else {if ( ! empty( $content_width ) && $atts['width'] > $content_width ) {$atts['height'] = round( ( $atts['height'] * $content_width ) / $atts['width'] );$atts['width'] = $content_width;}}$is_vimeo = $is_youtube = false;$yt_pattern = '#^https?://(?:www.)?(?:youtube.com/watch|youtu.be/)#';$vimeo_pattern = '#^https?://(.+.)?vimeo.com/.*#';$primary = false;if ( ! empty( $atts['src'] ) ) {$is_vimeo = ( preg_match( $vimeo_pattern, $atts['src'] ) );$is_youtube = ( preg_match( $yt_pattern, $atts['src'] ) );if ( ! $is_youtube && ! $is_vimeo ) {$type = wp_check_filetype( $atts['src'], wp_get_mime_types() );if ( ! in_array( strtolower( $type['ext'] ), $default_types ) ) {return sprintf( '<a class="wp-embedded-video" href="%s">%s</a>', esc_url( $atts['src'] ), esc_html( $atts['src'] ) );}}if ( $is_vimeo ) {wp_enqueue_script( 'mediaelement-vimeo' );}$primary = true;array_unshift( $default_types, 'src' );} else {foreach ( $default_types as $ext ) {if ( ! empty( $atts[ $ext ] ) ) {$type = wp_check_filetype( $atts[ $ext ], wp_get_mime_types() );if ( strtolower( $type['ext'] ) === $ext ) {$primary = true;}}}}if ( ! $primary ) {$videos = get_attached_media( 'video', $post_id );if ( empty( $videos ) ) {return;}$video = reset( $videos );$atts['src'] = wp_get_attachment_url( $video->ID );if ( empty( $atts['src'] ) ) {return;}array_unshift( $default_types, 'src' );}$library = apply_filters( 'wp_video_shortcode_library', 'mediaelement' );if ( 'mediaelement' === $library && did_action( 'init' ) ) {wp_enqueue_style( 'wp-mediaelement' );wp_enqueue_script( 'wp-mediaelement' );wp_enqueue_script( 'mediaelement-vimeo' );}if ( 'mediaelement' === $library ) {if ( $is_youtube ) {$atts['src'] = remove_query_arg( 'feature', $atts['src'] );$atts['src'] = set_url_scheme( $atts['src'], 'https' );} elseif ( $is_vimeo ) {$parsed_vimeo_url = wp_parse_url( $atts['src'] );$vimeo_src = 'https://' . $parsed_vimeo_url['host'] . $parsed_vimeo_url['path'];$loop = $atts['loop'] ?
