Paged posts - how to use numbers and next/previous links?

Question

I want wp_link_pages (mutli-page posts) to display the page numbers, the word "previous" before those numbers, and a "next" after those numbers. It would look like this:

Prev 1, 2, 3, 4 Next

I'm attempting to do this without a plugin. Here's what I've tried so far, but it isn't working, it is only displaying numbers.

<?php wp_link_pages(array(
    'before' => '<span style="clear:both; display:block">Pages', 
    'after'  => '</span>',
    'next_or_number'=>'number',
    'previouspagelink' => 'previous',
    'nextpagelink'=> 'Next'
)); ?>

Answer 1

The function you're using, wp_link_pages^­Codex, does not have the feature you're looking for by default.

However you can easily extend it by using a callback function, registered as a filter on that functions arguments:

add_filter('wp_link_pages_args', 'wp_link_pages_args_prevnext_add');

The filter will then modify the parameters that are used in that function on-the-fly and inject the missing links to the prev and next arguments which are output on the left and right side of the numbered link list (next_or_number' => 'number'):

/**
 * Add prev and next links to a numbered page link list
 */
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>'
        ;

    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']
        ;

    return $args;
}

Usage:

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

If your theme always uses the prev and next links, then you could change the function a little to make it the default behaviour whenever number (the default) is used, so you need to write less in your themes.

This is a slightly different implementation as suggested by Velvet Blues.

Answer 2

The wp_link_pages() function only shows either text or number, never both. If you take a look at the function's code, you'll see that there is no option to make it behave differently by passing parameters.

That being said, there are three ways to do this without a plugin:

1. Create your own function in your theme's functions.php file. Works, but then you'd have a new function.
2. Use 2-3 instances of wp_link_pages(). Very inefficient hack.
3. Use a filter. Preferred Method. See below.

I've written an article on how to do this on my blog. Basically, I use the wp_link_pages_args filter and add a function in the functions.php file which adds a new option 'next_and_number'.

Answer 3

Try this, you can more customize it. But it should do as you wanted :-)

function tp_link_pages() {
    global $page, $numpages;

    echo paginate_links( array(
        'format' => get_permalink() . '%#%/',
        'current' => $page,
        'total' => $numpages
    ) );
}

Answer 4

I don't get what's the problem... Do you have any error?

This should work:

<?php $args = array(
    'before'           => '<span style="clear:both; display:block">Pages',
    'after'            => '</span>',
    'nextpagelink'     => __('Next'),
    'previouspagelink' => __('Previous')
); 

wp_link_pages($args);
?> 

You don't need to add next_or_number as number is already the default.

Answer 5

This code is on the loop of posts? The coding is OK to me. Here is the Codex example on how to use:

<?php

wp_link_pages(array(
    'before' => '<p>' . __('Pages:'),
    'after' => '</p>',
    'next_or_number' => 'number',
    'nextpagelink' => __('Next page'),
    'previouspagelink' => __('Previous page'),
    'pagelink' => '%',
    'echo' => 1 )
);

?>

Answer 6

The answer is different, but it was inspired @荒野无灯 who decided to delete his answer. Imho it's the best, as the most easy and flexible solution:

The solution depends on paginate_links(). The only thing to know is that base will be the URl from the start, appended by %_%, which will then be replaced by format. So as long as we use get_permalink().'%_%';, we know that we will in any case stay on the current post. Inside format, the # gets replaced by the page number:

function wpse37256_paginate_paged()
{
    if ( ! $paginate_links = paginate_links( array(
         'type'      => 'array'

        ,'total'     => $GLOBALS['numpages']
        ,'mid_size'  => 1
        ,'end_size'  => 1

        #,'prev_next' => false
        ,'prev_text' => '« '.__( 'Prev', 'your_textdomain' )
        ,'next_text' => __( 'Next', 'your_textdomain' ).' »'

        ,'base'      => get_permalink().'%_%'
        ,'format'    => user_trailingslashit( '%#%' )

        ,'current'   => $GLOBALS['page']
    ) ) )
        return;

    echo "<div class='pagination-container'>{$paginate_links}</div>";
}
