Showing the Content of the ‘Posts Page’ before all Posts

If you have set a static front page, and defined a ‘posts page’, WordPress will use the index template to show the list of posts.
This also means that any content you might have entereed into the ‘posts page’ will not get shown.

Make sure to add any content before you set the page as the ‘posts page’; otherwise the editor will not be shown, and a warning message will be displayed instead.

To show this content of the ‘posts page’ before the list of posts, you can use following code (to be inserted into functions.php of a child theme, the html structure of the example below is based on Twenty Fourteen):

function page_content_on_posts_page() {
if( get_option( 'page_for_posts' ) && is_home() ) {
global $wp_query;
if( !is_paged() && $wp_query->current_post == 0 ) { ?>
<article id="post-<?php echo get_option( 'page_for_posts' ); ?>" class="<?php echo implode(  ', ', get_post_class( 'posts-page-content', get_option( 'page_for_posts' ) ) ); ?>">

<div class="entry-content">
echo apply_filters( 'the_content', get_post( get_option( 'page_for_posts' ) )->post_content );
</div><!-- .entry-content -->
</article><!-- #post-## -->
<?php }

add_action( 'the_post', 'page_content_on_posts_page' );



Comments on the ‘Posts Page’ in WordPress

If you are using a static home page and have set one of your other pages to be the ‘posts page‘ [Codex], then there is no direct way to allow comments on that page.

You will need to do some custom programming to allow viewers to comment on the ‘posts page‘, i.e. not just on the individual posts, but on the whole page in general.

WordPress does not use any page templates for the ‘posts page‘, but uses index.php or home.php of the currently active theme – see template hierarchy.

This example assumes that the theme does not have a home.php, so we are doing the coding in index.php.

First, we need to check that we are on the ‘posts page‘, and that is set under dashboard – settings – reading:

if( is_home() && get_option('page_for_posts') ) :

Then we get the ‘original’ page using WP_Query():

$posts_page = new WP_Query( array( 'post_type' => 'page', 'posts_per_page' => 1, 'post__in' => array(get_option('page_for_posts')) ) );

We could then for instance output the content of that page as it is written in the page editor; this content would otherwise not get shown for a ‘posts page’; or use ‘get_template_part(‘content’,’page’)’ as in the example for Twenty Twelve.

Last we output the comments and comment form with:

global $withcomments; $withcomments = 1;
$withcomments = 0; 

The $withcomments = 1;  is needed to show the comments part in a ‘posts page‘.

The full example code is:

<?php if( is_home() && get_option('page_for_posts') ) :
$posts_page = new WP_Query( array( 'post_type' => 'page', 'posts_per_page' => 1, 'post__in' => array(get_option('page_for_posts')) ) );
if( $posts_page->have_posts() ) while( $posts_page->have_posts() ) : $posts_page->the_post();
//this is for Twenty Twelve; or whatever you want to output from the 'posts page'
global $withcomments; $withcomments = 1;
$withcomments = 0;
endwhile; wp_reset_postdata();
endif; ?>

Show Page Title and Content of the ‘Posts Page’ in WordPress

When you set a static front page and at the same time set a Posts Page, WordPress will automatically use index.php (or home.php *) to display the Posts Page; as described in the Codex, you’ll lose the output of the title and content of that page.
To show this information on the Posts Page, for instance as an introduction for the posts, add some code to index.php (or home.php):

<?php //this is to output the page title and content for a 'page for posts' page as set under  'settings' - 'reading'
	if( is_home() && !is_paged() && get_option('page_for_posts') ) { 
	$posts_page_id = get_option('page_for_posts'); ?>			
	<header class="entry-header">
		<h1 class="entry-title"><?php echo get_the_title($posts_page_id); ?></h1>
	</header><!-- .entry-header -->
	<?php $posts_page = get_page( $posts_page_id ); ?>
	<div class="entry-content posts-page-entry-content">
	<?php echo apply_filters('the_content', $posts_page->post_content); ?>
	</div><!-- .posts-page-entry-content -->	
<?php } ?>
