Requests::request_multiple( array $requests, array $options = array() )

Send multiple HTTP requests simultaneously


Description

The $requests parameter takes an associative or indexed array of request fields. The key of each request can be used to match up the request with the returned data, or with the request passed into your multiple.request.complete callback.

The request fields value is an associative array with the following keys:

If the $options parameter is specified, individual requests will inherit options from it. This can be used to use a single hooking system, or set all the types to \WpOrg\Requests\Requests::POST, for example.

In addition, the $options parameter takes the following global options:

  • complete: A callback for when a request is complete. Takes two parameters, a \WpOrg\Requests\Response/\WpOrg\Requests\Exception reference, and the ID from the request array (Note: this can also be overridden on a per-request basis, although that’s a little silly) (callback)

Parameters

$requests

(Required) Requests data (see description for more information)

$options

(Optional) Global and default options (see WpOrgRequestsRequests::request())

Default value: array()


Return

(array) Responses (either WpOrgRequestsResponse or a WpOrgRequestsException object)
