我正在寻找从网站嵌入视频，不提供oembed支持。我写了一些代码，但不起作用。

链接示例：

https://openload.co/f/onU1gT5mkJ8/A_date_with_Lazar_Angelov.mp4

嵌入示例：

<iframe src="https://openload.co/embed/onU1gT5mkJ8/A_date_with_Lazar_Angelov.mp4" scrolling="no" frameborder="0" width="700" height="430" allowfullscreen="true" webkitallowfullscreen="true" mozallowfullscreen="true"></iframe>

我的代码：

  add_action( \'init\', function()
    {
        wp_embed_register_handler( 
            \'openload\', 
            \'#https://www\\.openload\\.co/f/([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)?#i\', 
            \'wp_embed_handler_openload\' 
        );

    } );

    function wp_embed_handler_openload( $matches, $attr, $url, $rawattr )
    {
        $embed = sprintf(
            \'<iframe class="openload-video" src="https://openload.co/embed/([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)" scrolling="no" frameborder="0" width="700" height="430" allowfullscreen="true" webkitallowfullscreen="true" mozallowfullscreen="true">></iframe>\',
            esc_attr( $matches[1] ) 
         );

        return apply_filters( \'embed_openload\', $embed, $matches, $attr, $url, $rawattr );
    }

我真的被这个搞砸了。如果您能提供任何有帮助的建议或信息链接，我将不胜感激。谢谢

$embed = sprintf(
    \'<iframe class="openload-video" src="https://openload.co/embed/%s" scrolling="no" frameborder="0" width="700" height="430" allowfullscreen="true" webkitallowfullscreen="true" mozallowfullscreen="true">></iframe>\',
    esc_attr(
        $matches[1]
    ) 
);
