以下是我使用的解决方案：

function wrap_embed_with_div($html, $url, $attr) {

     return \'<div class="video-container">\' . $html . \'</div>\';

}

 add_filter(\'embed_oembed_html\', \'wrap_embed_with_div\', 10, 3);

使用Wordpress过滤器。将此添加到您的函数中。php：

function div_wrapper($content) {
    // match any iframes
    $pattern = \'~<iframe.*</iframe>|<embed.*</embed>~\';
    preg_match_all($pattern, $content, $matches);

    foreach ($matches[0] as $match) {
        // wrap matched iframe with div
        $wrappedframe = \'<div>\' . $match . \'</div>\';

        //replace original iframe with new in content
        $content = str_replace($match, $wrappedframe, $content);
    }

    return $content;    
}
add_filter(\'the_content\', \'div_wrapper\');
