  1. Skip to note 1 content

    I looked long and hard in trying to find a working example of his function, (couldn’t!)
    The code below works, and it works well.

    Note 1: Without getting, (and using the post->ID), then the post_password_required function doesn’t work.
    Note 2: Something else you have to watch is cookies being set once the password has been used once, makes debugging a nightmare, (tip), use an Incognito Window when testing out your code.
    Note 3: I have broken with tradition here, and opened (the-Loop) with wide braces instead of the endwhile: condition, I personally find it easier to follow.

    Hope it helps.

    <?php
    
    $pass_masterPost = get_post();
    if ( post_password_required(  $pass_masterPost->ID ) )
    {
        echo get_the_password_form();
        echo '<p>THIS POST IS PASSWORD PROTECTED: PLEASE ENTER IT!</p>';
    }
    else
    {
        if ( have_posts() )
