Custom template for password protected page

Question

I have a password-protected page, for whom I'd like to use a custom template to query posts from a specific category. How can I achieve that query_posts should work only after users submit the password of the page? I'm trying with this but doesn't work (page only displays header and footer)

<?php
/*
Template Name: xxxx
*/
?>

        <?php get_header(); ?>
            <?php if ( post_password_required() ) : ?>
            <?php query_posts('cat=9'); ?>
            <?php while ( have_posts() ) : the_post(); ?>


            <a href="<?php the_permalink(); ?>"><h1 style="padding-top:0;margin-top:-5px" class="entry-title"><?php the_title(); ?></h1></a>
                <div class="entry-content" style="padding:0"><?php the_content(); ?></div>
                                        <div class="entry-meta">
                    <?php edit_post_link( __( 'Edit', 'twentyeleven' ), '<span class="edit-link">', '</span>' ); ?>
                    </div>


            <?php endwhile; ?>
            <?php endif; ?>


        <?php get_footer(); ?>

Answer 1

separate the queries for the current page and the query for all posts in a category.
Untested example:

<?php
/*
Template Name: xxxx
*/
?>

<?php while ( have_posts() ) : the_post(); ?>
<?php get_header(); ?>
<?php if ( post_password_required() ) :
    $args = array(
        'cat' => 9,
        'numberposts' => -1,
        );
    $posts = get_posts( $args );
    foreach( $posts as $post ) : setup_postdata($post); ?>
        <a href="<?php the_permalink(); ?>">
            <h1 style="padding-top:0;margin-top:-5px" class="entry-title"><?php the_title(); ?></h1>
        </a>
        <div class="entry-content" style="padding:0"><?php the_content(); ?></div>
        <div class="entry-meta">
            <?php edit_post_link( __( 'Edit', 'twentyeleven' ), '<span class="edit-link">', '</span>' ); ?>
        </div>
    <?php endforeach; ?>

<?php endif; ?>
<?php get_footer(); ?>
<?php endwhile; ?>
