Retrieving meta-box from a custom-post-type

Question

I am trying to display data from a custom post type on my home page, for which I am using a separate template.

I'm getting a Fatal error: Call to undefined method WP_Query::have_post() when my code looks like this:

get_header(); ?>
<div class="home_main_text">

<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( 'content', 'home' ); ?>
<?php endwhile; // end of the loop. ?>
</div><!-- #primary -->
<?php 
$current = date("d/m/Y");
$args = array('post_type' => 'jh_dedications');
$loop = new WP_Query($args);

    while ( $loop -> have_post() ) : $loop->the_post();
    the_title();
    endwhile;
    ?>

Answer 1

while ( $loop -> have_post() ) : $loop->the_post();

Your missing an s have_post() should be have_posts();

Your title says retrieving meta-box and I am assuming you mean the post_meta. Which you use the get_post_meta() function.
