Change Number Of Posts On Homepage Only

[chad1008]

Fought with this one all day, and I've gotten pretty close - just need a fresh pair of eyes to tell me what I'm missing.

I need my front page to display 3 posts, and all other pages (/page/2, etc.) to display a different number. Probably ten, but I'm testing with 2 as I don't have a huge database on my test site. The Blog Page template doesn't seem to allow for different post per page values.

Here's the code I've been playing with... The offsets all work fine, but for some reason every page is grabbing the homepage post count. The variable works fine and modifies the query, but it does it for every page.

add_action( 'pre_get_posts', 'w2wp_query_mod' );
function w2wp_query_mod( $query ) {
//Set up post count and pagination values
  global $paged;
  $homepage_count = 3;
  $otherpage_count = 2;
  $paged = $paged ? $paged : 1;

//Use homepage post count on first page with no offset
if ( $paged == 1 ) {
  $posts_per_page = $homepage_count;
  $offset = 0;

// Use other pages post count on second page, offset by homepage post count
} elseif ( $paged == 2 ) {
  $posts_per_page = $otherpage_count;
  $offset = $homepage_count;

// use other page post count on all other pages. Offset by number of posts displayed on the homepage, plus all other pages before the current.
} else {
  $posts_per_page = $otherpage_count;
  $offset = $homepage_count + ( $otherpage_count * ( $paged - 2 ) );
}
 
//Modify the query using the populated variables 
  if ( is_home() && $query->is_main_query() && !is_admin() ) {
		$query->set( 'posts_per_page', $posts_per_page );
		$query->set( 'post_type', array( 'post', 'w2wp_video' ) );
		$query->set( 'offset', $offset );
    
		return $query;
    }
}

The $paged values seem to work - I set up another function to output the current $paged value from the query, as well as the current $posts_per_page value from the above function - but that's always showing the $homepage_count value.

I've added this into a fresh, unmodified copy of Genesis Child, just to have a clean slate and I get the same result.

Any ideas? Hoping it's something painfully obvious that I've just overlooked!

I think you're over complicating things:

function custom_posts_per_page($query) {
    if (is_home()) {
        $query->set('posts_per_page',3);
    }
}  
add_action('pre_get_posts', 'custom_posts_per_page');

If you're not on the home page, the number of posts per page will be the value set in Admin Menu/Reading.

I don't this will work. When paginating the pages are all "home" - so whether you are on http://abc.com/page/2 or http://abc.com the call to is_home() will return true

it will not work. You will get wrong pagination number on home page. You need to re-create a new function of genesis pagination function.

Have you tried the Genesis Grid Loop plugin? I have it on my test site (here), and am able to get a different number of posts on my home page, versus other pages

[chad1008]

@Susuan That's good solution, but I think I'm too stubborn to give up on coding it myself 😉

@Genesis Developer

Okay, let me back up a step then. Before the query modification I posted above, I was working with this custom loop function:

remove_action ('genesis_loop', 'genesis_do_loop');
add_action( 'genesis_loop', 'w2wp_custom_loop' );

function w2wp_custom_loop() {
//Set up post count and pagination values
  global $paged;
  $homepage_count = 3;
  $otherpage_count = 2;
  $paged = $paged ? $paged : 1;

//Use homepage post count on first page with no offset
if ( $paged == 1 ) {
  $posts_per_page = $homepage_count;
  $offset = 0;

// Use other pages post count on second page, offset by homepage post count
} elseif ( $paged == 2 ) {
  $posts_per_page = $otherpage_count;
  $offset = $homepage_count;

// use other page post count on all other pages. Offset by number of posts displayed on the homepage, plus all other pages before the current.
} else {
  $posts_per_page = $otherpage_count;
  $offset = $homepage_count + ( $otherpage_count * ( $paged - 2 ) );
}

      global $query_args; // grab the current wp_query() args
      $args = array(
          'posts_per_page' => $posts_per_page,
          'offset' => $offset, 
          'paged'            => $paged, // respect pagination
          'post_type' => array( 'post', 'w2wp_video' )
      );
   
      genesis_custom_loop( wp_parse_args($query_args, $args) );
   
}

The pagination and offsets all work! The only problem is that I get a 404 message displaying after the posts on any page that shouldn't exist based on the post count value in Reading Settings. Any suggestions?

[Susan]

@chad1008 - I understand! I know some people don't like to use extra plugins, but others are just wanting a quick fix. 🙂

[Genesis Developer]

You should clean your custom code ( keep a backup first ) and then add the following code in functions.php file

$first_page_limit = 5;
$posts_per_page = $next_pages_limit = 10;
        
//add_filter( 'pre_get_posts', 'mwm_posts_per_page_archive_query' );
function mwm_posts_per_page_archive_query( $query ) {

    if ( is_admin() || is_feed() || ! $query->is_main_query() ) {
        return $query;
    }

    global $first_page_limit, $next_pages_limit, $posts_per_page;
    $paged = get_query_var( 'paged' ) ? absint( get_query_var( 'paged' ) ) : 1;
    
    if ( is_home() ) {

        if ( $paged == 1 ) {
            $posts_per_page = $first_page_limit;
        } else {
           $offset = $first_page_limit + (($paged - 2) * $next_pages_limit);
            set_query_var('offset', $offset);
        }
        set_query_var('posts_per_archive_page', $posts_per_page);
        set_query_var('posts_per_page', $posts_per_page);
        
        remove_action( 'genesis_after_endwhile', 'genesis_posts_nav' ); 
        add_action( 'genesis_after_endwhile', 'gd_custom_posts_nav' );
    }

    return $query;  
}

function gd_custom_posts_nav(){
  
  if ( 'numeric' === genesis_get_option( 'posts_nav' ) )
		gd_numeric_posts_nav();
	else
		genesis_prev_next_posts_nav();
}

function gd_numeric_posts_nav() {

	if( is_singular() )
		return;

	global $wp_query, $first_page_limit, $next_pages_limit;

	//* Stop execution if there's only 1 page
	if( $wp_query->max_num_pages <= 1 )
		return;
    
  $paged = get_query_var( 'paged' ) ? absint( get_query_var( 'paged' ) ) : 1;
	
  $found_posts = $wp_query->found_posts - $first_page_limit;
  $max = $wp_query->max_num_pages = intval( ceil( $found_posts / $next_pages_limit ) ) + 1;

	//* Add current page to the array
	if ( $paged >= 1 )
		$links[] = $paged;

	//* Add the pages around the current page to the array
	if ( $paged >= 3 ) {
		$links[] = $paged - 1;
		$links[] = $paged - 2;
	}

	if ( ( $paged + 2 ) <= $max ) {
		$links[] = $paged + 2;
		$links[] = $paged + 1;
	}

	genesis_markup( array(
		'html5'   => '<div %s>',
		'xhtml'   => '<div class="navigation">',
		'context' => 'archive-pagination',
	) );

	echo '<ul>';

	//* Previous Post Link
	if ( get_previous_posts_link() )
		printf( '<li class="pagination-previous">%s</li>' . "\n", get_previous_posts_link( apply_filters( 'genesis_prev_link_text', '«' . __( 'Previous Page', 'genesis' ) ) ) );

	//* Link to first page, plus ellipses if necessary
	if ( ! in_array( 1, $links ) ) {

		$class = 1 == $paged ? ' class="active"' : '';

		printf( '<li%s><a href="%s">%s</a></li>' . "\n", $class, esc_url( get_pagenum_link( 1 ) ), '1' );

		if ( ! in_array( 2, $links ) )
			echo '<li class="pagination-omission">…</li>';

	}

	//* Link to current page, plus 2 pages in either direction if necessary
	sort( $links );
	foreach ( (array) $links as $link ) {
		$class = $paged == $link ? ' class="active"' : '';
		printf( '<li%s><a href="%s">%s</a></li>' . "\n", $class, esc_url( get_pagenum_link( $link ) ), $link );
	}

	//* Link to last page, plus ellipses if necessary
	if ( ! in_array( $max, $links ) ) {

		if ( ! in_array( $max - 1, $links ) )
			echo '<li class="pagination-omission">…</li>' . "\n";

		$class = $paged == $max ? ' class="active"' : '';
		printf( '<li%s><a href="%s">%s</a></li>' . "\n", $class, esc_url( get_pagenum_link( $max ) ), $max );

	}

	//* Next Post Link
	if ( get_next_posts_link() )
		printf( '<li class="pagination-next">%s</li>' . "\n", get_next_posts_link( apply_filters( 'genesis_next_link_text', __( 'Next Page', 'genesis' ) . '»' ) ) );

	echo '</ul></div>' . "\n";

Unreal.

That's awesome - even solves the problem of the phantom navigation links that I was going to have to tackle next.

Just saved me a ton of time working all of that out... Thanks a MILLION.
