Good find! Where does this script go in the file directory? Does it go in the root of the wordpress-seo folder, within a subfolder, appended to file?…

Hi dlngle,

Thanks for the response. I added this inside a custom plugin:

add_action( 'the_post', array( &$this, 'get_post_info') );

	function get_post_info() {
	    global $post;
	    var_dump( $post );
	    }

But, I get this error:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, first array member is not a valid class name or object in /Applications/XAMPP/xamppfiles/htdocs/wp-includes/plugin.php on line 507

That code is literally all I have in the plugin. It gives that error when I go into any post. I literally just want to be able to pull data about the current post. Any ideas?

I just threw this together. It’s really hacky, but it works:

add_filter('wp_link_pages_args', 'wp_link_pages_args_prevnext_add');

function wp_link_pages_args_prevnext_add($args) {
    global $page, $numpages, $more, $pagenow;

    if (!$args['next_or_number'] == 'next_and_number')
        return $args; # exit early

    $args['next_or_number'] = 'number'; # keep numbering for the main part
    if (!$more)
    	return $args; # exit early

    if($page - 1) { # there is a previous page
        $args['before'] .= _wp_link_page($page - 1)
            . $args['link_before']. $args['previouspagelink'] . $args['link_after'] . '</a>';
		} else { # First page of pagination

			$prev_url = get_permalink(get_adjacent_post(false, '', true));
			$args['before'] = '<div class="page-links"><a href="'.$prev_url.'">Last</a>';		

			}

    if ($page < $numpages) { # there is a next page
        $args['after'] = _wp_link_page($page + 1)
            . $args['link_before'] . $args['nextpagelink'] . $args['link_after'] . '</a>'
            . $args['after'];
		} else { # Last page of pagination

			$next_url = get_permalink(get_adjacent_post(false, '', false));
			$args['after'] = '<a href="'.$next_url.'">Next</a>';

			}

    return $args;
}

function wp_link_pages( $args = '' ) {
	$defaults = (array(
    'before' => '<p>' . __('Pages:'),
    'after' => '</p>',
    'next_or_number' => 'next_and_number', # activate parameter overloading
    'nextpagelink' => __('Next'),
    'previouspagelink' => __('Last'),
    'pagelink' => '%',
    'echo' => 1 )
	);

	$r = wp_parse_args( $args, $defaults );
	$r = apply_filters( 'wp_link_pages_args', $r );
	extract( $r, EXTR_SKIP );

	global $page, $numpages, $multipage, $more;

	$output = '';
	if ( $multipage ) {
		if ( 'number' == $next_or_number ) {
			$output .= $before;
			for ( $i = 1; $i <= $numpages; $i++ ) {
				$link = $link_before . str_replace( '%', $i, $pagelink ) . $link_after;
				if ( $i != $page || ! $more && 1 == $page )
					$link = _wp_link_page( $i ) . $link . '</a>';
				$link = apply_filters( 'wp_link_pages_link', $link, $i );
				$output .= $separator . $link;
			}
			$output .= $after;
		} elseif ( $more ) {
			$output .= $before;
			$i = $page - 1;
			if ( $i ) {
				$link = _wp_link_page( $i ) . $link_before . $previouspagelink . $link_after . '</a>';
				$link = apply_filters( 'wp_link_pages_link', $link, $i );
				$output .= $separator . $link;
			}
			$i = $page + 1;
			if ( $i <= $numpages ) {
				$link = _wp_link_page( $i ) . $link_before . $nextpagelink . $link_after . '</a>';
				$link = apply_filters( 'wp_link_pages_link', $link, $i );
				$output .= $separator . $link;
			}
			$output .= $after;
		}
	}

	$output = apply_filters( 'wp_link_pages', $output, $args );

	if ( $echo )
		echo $output;

	return $output;
}

The only setbacks are these:

If you’re on the first tab, the last button will bring you to the first tab of the previous article (not the last tab). I’m sure I can figure out a way to fix that, it might actually be better how it is. Everything else is functional.

You can see it working HERE. The “Next” button brings you to the next article. Then the “Last” button on the next article brings you back to the first tab of the previous article (There’s only 2 articles at this point in time, so it’s not ideal for demonstration purposes).

Thanks xavortm!

Wow thanks man. I used the code from stack exchange and it worked perfectly. If anyone’s wondering, just overwrite the entire wp_link_pages function with this:

add_filter('wp_link_pages_args', 'wp_link_pages_args_prevnext_add');

function wp_link_pages_args_prevnext_add($args)
{
    global $page, $numpages, $more, $pagenow;

    if (!$args['next_or_number'] == 'next_and_number')
        return $args; # exit early

    $args['next_or_number'] = 'number'; # keep numbering for the main part
    if (!$more)
        return $args; # exit early

    if($page-1) # there is a previous page
        $args['before'] .= _wp_link_page($page-1)
            . $args['link_before']. $args['previouspagelink'] . $args['link_after'] . ''
        ;

    if ($page<$numpages) # there is a next page
        $args['after'] = _wp_link_page($page+1)
            . $args['link_before'] . $args['nextpagelink'] . $args['link_after'] . ''
            . $args['after']
        ;

    return $args;
}

function wp_link_pages( $args = '' ) {
	$defaults = (array(
    'before' => '<p>' . __('Pages:'),
    'after' => '</p>',
    'next_or_number' => 'next_and_number', # activate parameter overloading
    'nextpagelink' => __('Next'),
    'previouspagelink' => __('Previous'),
    'pagelink' => '%',
    'echo' => 1 )
);
