wp_oembed_add_host_js()WP 4.4.0

Deprecated from version 5.9.0. It is no longer supported and can be removed in future releases. See {@see wp_maybe_enqueue_oembed_host_js()}.

Adds the necessary JavaScript to communicate with the embedded iframes.

This function is no longer used directly. For back-compat it exists exclusively as a way to indicate that the oEmbed host JS _should_ be added. In default-filters.php there remains this code:

add_action( 'wp_head', 'wp_oembed_add_host_js' )

Historically a site has been able to disable adding the oEmbed host script by doing:

remove_action( 'wp_head', 'wp_oembed_add_host_js' )

In order to ensure that such code still works as expected, this function remains. There is now a has_action() in wp_maybe_enqueue_oembed_host_js() see if wp_oembed_add_host_js() not been unhooked from running at the wp_head

No Hooks.

Return

null. Nothing.

Usage

wp_oembed_add_host_js();
