How to use post_password_expires filter in WordPress

Example 1: Basic Usage

In this example, we’ll see how to apply the post_password_expires filter to modify the cookie expiry time. The code snippet shows the application of the filter.

    $time = apply_filters( 'post_password_expires', $time ); 
                             
    if ( !empty( $time ) ) { 
        // everything has led up to this point... 
    } 
    

Example 2: Adding a Hook Callback

Let’s add a callback to the post_password_expires filter. This will allow us to modify the expiry time with our custom logic.

    // define the post_password_expires callback 
    function weplugins_filter_post_password_expires( $time ) { 
        // make filter magic happen here... 
        return $time; 
    }; 
             
    // add the filter 
    add_filter( 'post_password_expires', 'weplugins_filter_post_password_expires', 10, 1 ); 
    

Example 3: Modifying Cookie Expiry

In this example, we’ll customize the cookie to expire after 10 minutes. Adjust the time as needed to suit your specific requirements.

    function weplugins_modif_expir_cookie( $time ) { 
        return time() + 600;  // 10 minutes
        // for 5 minutes :  
        // return time() + 300;  in this case 60 * 5 
        // return 0; set cookie to expire at the end of the session
    }
    add_filter('post_password_expires', 'weplugins_modif_expir_cookie' );
