Custom Field: Post on page

Not sure why you would need a custom field. You can just use a second loop like this:

<?php $my_query = new WP_Query('posts_per_page=1');
if ($my_query->have_posts()) : while ($my_query->have_posts()) : $my_query->the_post();
   // Code to display the post
endwhile; endif;
?>

You can get more info from the Codex:The Loop/Multiple Loops.

Thnx.
I thought the custom field was a good way to go. But futher reading I have discarded that thought. I guess the solution is to put it inside the loop.
I’m still not sure how to proceed.

If you are using a free theme, post a link to your site and I will take a look.

Thnx you very much.
The site is in Danish, but here’s the URL:
https://www.ekstremisme.dk/

Locate <div id="right"> in index.php and paste in the code shown below (don’t include <div id="right">):

<div id="right">
     <div class="leftcol latest-post">
       <?php
         $my_query = new WP_Query('posts_per_page=1&caller_get_posts=1');
         while ($my_query->have_posts()) : $my_query->the_post();
            setup_postdata($post);
            $do_not_duplicate = $post->ID; ?>
            <div <?php if (function_exists('post_class')) { post_class(); } else { echo 'class="post"'; } ?> id="post-<?php the_ID(); ?>">
            <h2>The Latest Post</h2>
            <h3><a href="<?php the_permalink(); ?>" class="posttitle" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h3>
            <?php the_content(); ?>
            <?php if (function_exists('the_tags')) { ?>
            <?php the_tags('<p>Tags: ', ', ', '</p>'); ?>
            <?php } ?>
            <div class="metadata"><?php the_time('d M y'); ?> | <?php the_category(', ') ?> | <a href="<?php the_permalink() ?>">Read on</a> | <?php comments_popup_link('Comments (0)', 'Comment (1)', 'Comments (%)'); ?><?php edit_post_link('Edit',' | ',''); ?></div>
            </div>
         <?php endwhile;
         wp_reset_query(); ?>
       </div>

Then, change this:

<div class="leftcol">
        <?php if (have_posts()) : while (have_posts()) : the_post(); ?>

to this:

<div class="leftcol">
        <?php if (have_posts()) : while (have_posts()) : the_post();
             if ($post->ID == $do_not_duplicate) continue; update_post_caches($posts); ?>

Thnx you very much. I’ll give it a try.

Couldn’t get it to work.
But I tried with the following

<?php if ( is_front_page() ) { ?>
        <?php
	query_posts('showposts=1');
	if (have_posts()) : while (have_posts()) : the_post(); ?>
		<div>
			<h3 id="post-<?php the_ID(); ?>"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h3>

			<?php the_excerpt(); ?>
		</div>
	<?php endwhile; else: endif; ?>
	<?php wp_reset_query() ?>
<?php } ?>

I sort of works, now I have to figure out have to get rid of the few glitches and add a seperate box for the post.

You might want to change showposts to posts_per_page, as showposts is deprecated. Also, if you ever plan to use sticky posts, you will want to add ‘caller_get_posts=1’ to ignore the sticky posts. Otherwise you will always get the same sticky post every time.

Thnx for the heads up.
I have made the suggested adjustments.

If I understand what you mean by ‘add a seperate box for the post’, I think that the box might be controlled by the div classes. Try enclosing your code in <div class="leftcol"> ... </div> tags instead of the plain tags:

<div class="leftcol">
   <h3 id="post-<?php the_ID(); ?>"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h3>

   <?php the_excerpt(); ?>
</div>
