Custom Fields isn't Working in WordPress

Question

I've created an hours of operation widget in the sidebar. It's not outputting the values that are set within the Home page template. This is located in the sidebar include file. Could that be affecting it?

<div class="widget" id="hours">
    <?php $hours = get_post_meta($post->ID, 'hours', false); ?>
    <div class="widget-title">Business Hours:</div>
    <ul>
        <?php foreach($hours as $hour) {
            echo '<li>'.$hour.'</li>';
          } ?>
    </ul>
</div>

Answer 1

I figured it out. I needed to specify that it was pulling from a page not a post:

<?php query_posts('post_type=page'); ?>
   <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
        <?php $hours = get_post_meta($post->ID, 'hours', false); ?>
        <ul>
            <?php foreach($hours as $hour) {
                echo '<li>'.$hour.'</li>';
            } ?>
        </ul>
   <?php endwhile; ?>
   <?php endif; ?>

Answer 2

It could be that a sidebar widget query has affected the post data and not reset it back to the main query. To be sure you're accessing the correct post's meta perform a reset and get the global. Example below:

<div class="widget" id="hours">
    <?php wp_reset_postdata();
    global $post;
    $hours = get_post_meta($post->ID, 'hours', false); ?>
    <div class="widget-title">Business Hours:</div>
    <ul>
        <?php foreach($hours as $hour) {
            echo '<li>'.$hour.'</li>';
          } ?>
    </ul>
</div>
