How to use http_request_redirection_count filter in WordPress

http_request_redirection_count filter

Filters the number of redirects allowed during an HTTP request.

To use the http_request_redirection_count 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 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 modify_http_request_redirection_count_defaults which takes 2 parameters and we registered it using add_filter. The first parameter http_request_redirection_count is the name of the hook, the second parameter modify_http_request_redirection_count_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_redirection_count filter.

Parameters

Below are the 2 parameters required to use this hook:

• $redirect_count: (int) Number of redirects allowed. Default 5.
• $url: (string) The request URL.

Live Examples

Example 1: Basic Usage

Below is an example of how you can use this hook:

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

Example 2: Conditional Modification

In this example, we modify the redirect count conditionally based on the URL:

    function weplugins_modify_http_request_redirection_count_conditionally($redirect_count, $url) {
        if (strpos($url, 'example.com') !== false) {
            $redirect_count = 3;
        }
        return $redirect_count;
    }
    // Add the filter
    add_filter("http_request_redirection_count", "weplugins_modify_http_request_redirection_count_conditionally", 10, 2);
    

Example 3: Removing the Hook

To remove a hook callback, use the example below:

    remove_filter("http_request_redirection_count", "weplugins_modify_http_request_redirection_count_defaults", 10, 2);
    

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