pre_oembed_result filter

This allows one to short-circuit the default logic, perhaps by replacing it with a routine that is more optimal for your setup.

To use pre_oembed_result filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at Flipper Code, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_pre_oembed_result_defaults which takes 3 parameters and we registered using add_filter. The first parameter pre_oembed_result is name of the hook, The second parameter modify_pre_oembed_result_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_filter to remove pre_oembed_result filter.


    Below are the 3 parameters are required to use this hook.

  • $result : (null|string) The UNSANITIZED (and potentially unsafe) HTML that should be used to embed. Default null to continue retrieving the result.
  • $url : (string) The URL to the content that should be attempted to be embedded.
  • $args : (string|array) Additional arguments for retrieving embed HTML. See wp_oembed_get() for accepted arguments. Default empty.

Live Example

apply_filters( 'pre_oembed_result', null|string $result, string $url, string|array $args )

Below is an example how you can use this hook.

                        function modify_pre_oembed_result_defaults($result, $url, $args) { 
                            // Update the $result variable according to your website requirements and return this variable. You can modify the $result variable conditionally too if you want.

                            return $result; 
                        // add the filter
                        add_filter( "pre_oembed_result", "modify_pre_oembed_result_defaults", 10, 3 );

To remove a hook callback, use the example below.

remove_filter( "pre_oembed_result", "modify_pre_oembed_result_defaults", 10, 3 );

Please make sure provide the same callback function name, priority and number of arguments while removing the hook callback.
