How to use nonce_life filter in WordPress

Example 1: Modifying Nonce Lifespan

In this example, we’ll create a function that modifies the default lifespan of a nonce. This is useful if you need nonces to expire sooner or last longer than the default 86,400 seconds (one day).

    function weplugins_modify_nonce_life($lifespan) { 
        // Customize the lifespan according to your needs
        return 7200; // Set lifespan to 2 hours
    }
    // Add the filter
    add_filter( "nonce_life", "weplugins_modify_nonce_life", 10, 1 );
    

Example 2: Conditional Nonce Lifespan

Sometimes, you might want to adjust the nonce lifespan based on certain conditions, like user roles or specific situations.

    function weplugins_conditional_nonce_life($lifespan) {
        if ( current_user_can( 'administrator' ) ) {
            $lifespan = 3600; // 1 hour for admins
        }
        return $lifespan;
    }
    // Add the filter
    add_filter( "nonce_life", "weplugins_conditional_nonce_life", 10, 1 );
    

Example 3: Removing the Nonce Filter Callback

If you need to remove a previously registered nonce filter, you can do so easily with the remove_filter function.

    // Remove the filter
    remove_filter( "nonce_life", "weplugins_modify_nonce_life", 10, 1 );
    

Make sure to use the same callback function name, priority, and number of arguments when removing the hook.
