pre_http_request filter-hook . WP 2.9.0

Filters whether to preempt an HTTP request's return value.

Returning a non-false value from the filter will short-circuit the HTTP request and return early with that value. A filter should return either:

  • An array containing 'headers', 'body', 'response', 'cookies', and 'filename' elements
  • A WP_Error instance
  • boolean false (to avoid short-circuiting the response)

Returning any other value may result in unexpected behaviour.


add_filter( 'pre_http_request', 'filter_function_name_337', 10, 3 );
function filter_function_name_337( $preempt, $r, $url ){
	// filter...

	return $preempt;
