php - Wordpress中的PHP函数不显示嵌入式YouTube视频

Question

php代码正在运行，并且正在显示联系表单和画廊，但是，youtube视频链接没有像在正常的Wordpress页面中那样嵌入。它只是在弹出窗口中显示地址。当在页面上使用html代码时，此方法有效，但在PHP函数中一次无效。如果有人可以帮助，这是代码。谢谢。

Answer 1

do_shortcode不会查找oEmbeds。您必须直接调用oEmbed代码，但是在oEmbed代码查看您的内容之前，需要先进行一些设置。

代替这个

return do_shortcode($output);

…您需要执行以下操作:

// Use the WP_Embed instance WordPress already set up
global $wp_embed;

/**
 * Replace the global $post with a fake ID (a really crazy one!)
 * or else WP_Embed::autoembed() will skip the oEmbed check
 * for some reason.
 **/
global $post;
$oldpost = $post;
$post = new stdClass();
$post->ID = PHP_INT_MAX;

// Process oEmbeds
$output = $wp_embed->autoembed( do_shortcode( $output ) );

// Restore the original $post
$post = $oldpost;

return $output;
