PHP函數不顯示內嵌YouTube影片

Question

PHP代碼工作，並顯示聯繫人的形式和畫廊，然而，YouTube視頻鏈接不embeding就像他們在正常的WordPress的頁面。它只是在彈出窗口中顯示地址。這在使用頁面上的html代碼時起作用，但在PHP函數中不起作用。如果任何人都可以提供幫助，這裏是代碼。謝謝。

Answer 1

do_shortcode不尋找oEmbeds。您必須直接調用oEmbed代碼，但在oEmbed代碼查看您的內容之前需要先完成一些設置。

取而代之的是...

return do_shortcode($output); 

...你需要做這樣的事情：

// 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;
