How to use pre_http_send_through_proxy filter in WordPress

As a fellow WordPress enthusiast, you might have come across various hooks that allow you to extend and modify functionality without altering core files. One such hook is the pre_http_send_through_proxy filter. This handy hook lets you control whether requests are sent through a proxy or not. By returning false, you bypass the proxy; returning true sends the request through, and null bypasses the filter altogether.

To get started with the pre_http_send_through_proxy filter, you’ll need to register it using add_filter. This can be done in your theme’s functions.php file or, ideally, in a custom WordPress Plugin. Creating a custom plugin is a great practice as it ensures your modifications remain intact through theme updates. Let’s dive into some live examples to understand this better.

Example 1: Modifying Proxy Behavior

In this example, we define a function weplugins_modify_pre_http_send_through_proxy_defaults that customizes proxy behavior based on your website’s needs.

  function weplugins_modify_pre_http_send_through_proxy_defaults($override, $uri, $check, $home) {
      // Your custom logic here
      return $override;
  }
  add_filter("pre_http_send_through_proxy", "weplugins_modify_pre_http_send_through_proxy_defaults", 10, 4);
  

Example 2: Removing a Hook Callback

If you need to remove a hook callback, use the example below. Ensure you provide the same callback function name, priority, and number of arguments.

  remove_filter("pre_http_send_through_proxy", "weplugins_modify_pre_http_send_through_proxy_defaults", 10, 4);
  

Parameters

Below are the parameters required for using this hook:

• $override: (bool|null) Whether to send the request through the proxy. Default null.
• $uri: (string) URL of the request.
• $check: (array) Result of parsing the request URL with parse_url().
• $home: (array) Result of parsing the site URL with parse_url().
