How to use http_origin filter in WordPress

http_origin filter

Change the origin of an HTTP request.

To use the `http_origin` 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.

At WePlugins, we 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_origin_defaults` which takes 1 parameter and we registered it using `add_filter`. The first parameter `http_origin` is the name of the hook, the second parameter `weplugins_modify_http_origin_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_origin` filter.

Parameters

Below the 1 parameter is required to use this hook.

• $origin: (string) The original origin for the request.

Live Example

apply_filters( 'http_origin', string $origin )

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

Example 1: Modify HTTP Origin

In this example, we modify the HTTP origin and return the updated value.

    function weplugins_modify_http_origin_defaults($origin) { 
        // Update the $origin variable according to your website requirements and return this variable. You can modify the $origin variable conditionally too if you want.
        return $origin; 
    }
    // add the filter
    add_filter( "http_origin", "weplugins_modify_http_origin_defaults", 10, 1 );
    

Example 2: Conditional HTTP Origin Change

Here, we change the origin based on a specific condition.

    function weplugins_conditionally_modify_http_origin($origin) {
        if (some_condition()) {
            $origin = 'https://new-origin.example.com';
        }
        return $origin;
    }
    add_filter( 'http_origin', 'weplugins_conditionally_modify_http_origin', 10, 1 );
    

Example 3: Removing the HTTP Origin Filter

To remove a hook callback, use the example below.

    remove_filter( "http_origin", "weplugins_modify_http_origin_defaults", 10, 1 );
    

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