How to use http_request_reject_unsafe_urls filter in WordPress

http_request_reject_unsafe_urls filter

Filters whether to pass URLs through wp_http_validate_url() in an HTTP request.

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

We at WePlugins 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 weplugins_modify_http_request_reject_unsafe_urls_defaults which takes 2 parameters and we registered using add_filter. The first parameter http_request_reject_unsafe_urls is the name of the hook, the second parameter weplugins_modify_http_request_reject_unsafe_urls_defaults is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook so you can use remove_filter to remove the http_request_reject_unsafe_urls filter.

Parameters

Below are the 2 parameters required to use this hook.

• $pass_url : (bool) Whether to pass URLs through wp_http_validate_url(). Default false.
• $url : (string) The request URL.

Live Example 1

This example shows how you can use this hook to modify the $pass_url variable.

    function weplugins_modify_http_request_reject_unsafe_urls_defaults($pass_url, $url) { 
        // Update the $pass_url variable according to your website requirements and return this variable. 
        // You can modify the $pass_url variable conditionally too if you want.
        return $pass_url; 
    }
    // add the filter
    add_filter("http_request_reject_unsafe_urls", "weplugins_modify_http_request_reject_unsafe_urls_defaults", 10, 2);
    

Live Example 2

To remove a hook callback, use the example below.

    remove_filter("http_request_reject_unsafe_urls", "weplugins_modify_http_request_reject_unsafe_urls_defaults", 10, 2);
    

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

Live Example 3

Another way to modify the $pass_url based on specific conditions.

    function weplugins_conditionally_modify_http_request_reject_unsafe_urls($pass_url, $url) {
        if (strpos($url, 'example.com') !== false) {
            $pass_url = true; // Example condition
        }
        return $pass_url;
    }
    add_filter("http_request_reject_unsafe_urls", "weplugins_conditionally_modify_http_request_reject_unsafe_urls", 10, 2);
