How to use nonce_user_logged_out filter in WordPress

nonce_user_logged_out filter

Filters whether the user who generated the nonce is logged out.

To use the nonce_user_logged_out 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 weplugins_modify_nonce_user_logged_out_defaults which takes 2 parameters and we registered it using add_filter. The first parameter nonce_user_logged_out is the name of the hook, the second parameter weplugins_modify_nonce_user_logged_out_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 nonce_user_logged_out filter.

Parameters

Below are the 2 parameters required to use this hook.

• $uid: (int) ID of the nonce-owning user.
• $action: (string) The nonce action.

Live Examples

Example 1: Basic Usage

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

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

Example 2: Removing a Hook Callback

To remove a hook callback, use the example below.

    remove_filter( "nonce_user_logged_out", "weplugins_modify_nonce_user_logged_out_defaults", 10, 2 );
    

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

Example 3: Conditional Modification

Modify the $uid variable conditionally based on a specific action.

    function weplugins_modify_nonce_user_logged_out_conditionally($uid, $action) { 
        if ($action === 'special_action') {
            // Perform a specific modification
            $uid = 0; // Example modification
        }
        return $uid;
    }
    // add the filter
    add_filter( "nonce_user_logged_out", "weplugins_modify_nonce_user_logged_out_conditionally", 10, 2 );
