无法使用添加到自定义字段的自托管视频URL实现此功能。

function video() {


$self_hosted           = get_post_meta( get_the_ID(), \'self_hosted\', true );

$video_self_hosted     = $self_hosted ? $self_hosted : get_theme_mod( \'customizer-video\' ); 

$video_src_url         = wp_get_attachment_url( $video_self_hosted ); 


if ( $video_src_url ) {

        echo \'<div class="video-container">\';

        $attr = array(
            \'src\' => $video_src_url,
            \'poster\'  => $video_thumb,
            \'preload\' => \'none\',
        );

        echo wp_video_shortcode( $attr );
        echo \'</div>\';

    }

}

get_theme_mod( \'video-upload\' ); equals the default video added via the customizer which displays but the URL from the custom field doesn\'t. 

如果通过名为“self\\u hosted”的自定义字段添加视频URL，我需要改用它，但它不起作用。

function video() {

$self_hosted = get_post_meta( get_the_ID(), \'self_hosted\', true );

$video_src_url = $self_hosted ? $self_hosted : wp_get_attachment_url( get_theme_mod( \'customizer-video\' ) );

if ( $video_src_url ) {

        echo \'<div class="video-container">\';

        $attr = array(
            \'src\' => $video_src_url,
            \'poster\'  => $video_thumb,
            \'preload\' => \'none\',
        );

        echo wp_video_shortcode( $attr );
        echo \'</div>\';

    }

}
