<p>Want to replace the old <em>← Older posts | Newer posts →</em> links with some page links?</p>
<p>This plugin provides the <code>wp_pagenavi()</code> template tag which generates fancy pagination links.</p>
<h3>Usage</h3>
<p>In your theme, you need to find calls to next_posts_link() and previous_posts_link() and replace them.</p>
<p>In the Twentyten theme, it looks like this:</p>
<pre><code><div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav">&larr;</span> Older posts', 'twentyten' ) ); ?></div>
<div class="nav-next"><?php previous_posts_link( __( 'Newer posts <span class="meta-nav">&rarr;</span>', 'twentyten' ) ); ?></div>
</code></pre>
<p>You would replace those two lines with this:</p>
<pre><code><?php wp_pagenavi(); ?>
</code></pre>
<p>For multipart pages, you would look for code like this:</p>
<pre><code><?php wp_link_pages( ... ); ?>
</code></pre>
<p>and replace it with this:</p>
<pre><code><?php wp_pagenavi( array( 'type' => 'multipart' ) ); ?>
</code></pre>
<p>Go to <em>WP-Admin -> Settings -> PageNavi</em> for configuration.</p>
<h3>Changing the CSS</h3>
<p>If you need to configure the CSS style of WP-PageNavi, you can copy the <code>pagenavi-css.css</code> file from the plugin directory to your theme’s directory and make your modifications there. This way, you won’t lose your changes when you update the plugin.</p>
<p>Alternatively, you can uncheck the “Use pagenavi.css?” option from the settings page and add the styles to your theme’s style.css file directly.</p>
<h3>Changing Class Names</h3>
<p>There are <a href="https://codex.wordpress.org/Glossary#Filter" rel="nofollow ugc">filters</a> that can be used to change the default class names that are assigned to page navigation elements.</p>
<h4>Filters</h4>
<ul>
<li><code>wp_pagenavi_class_pages</code></li>
<li><code>wp_pagenavi_class_first</code></li>
<li><code>wp_pagenavi_class_previouspostslink</code></li>
<li><code>wp_pagenavi_class_extend</code></li>
<li><code>wp_pagenavi_class_smaller</code></li>
<li><code>wp_pagenavi_class_page</code></li>
<li><code>wp_pagenavi_class_current</code></li>
<li><code>wp_pagenavi_class_larger</code></li>
<li><code>wp_pagenavi_class_nextpostslink</code></li>
<li><code>wp_pagenavi_class_last</code></li>
</ul>
<h4>Filter Usage</h4>
<pre><code>// Simple Usage - 1 callback per filter
add_filter('wp_pagenavi_class_previouspostslink', 'theme_pagination_previouspostslink_class');
add_filter('wp_pagenavi_class_nextpostslink', 'theme_pagination_nextpostslink_class');
add_filter('wp_pagenavi_class_page', 'theme_pagination_page_class');

function theme_pagination_previouspostslink_class($class_name) {
  return 'pagination__control-link pagination__control-link--previous';
}

function theme_pagination_nextpostslink_class($class_name) {
  return 'pagination__control-link pagination__control-link--next';
}

function theme_pagination_page_class($class_name) {
  return 'pagination__current-page';
}


// More Concise Usage - 1 callback for all filters
add_filter('wp_pagenavi_class_previouspostslink', 'theme_pagination_class');
add_filter('wp_pagenavi_class_nextpostslink', 'theme_pagination_class');
add_filter('wp_pagenavi_class_page', 'theme_pagination_class');

function theme_pagination_class($class_name) {
  switch($class_name) {
    case 'previouspostslink':
      $class_name = 'pagination__control-link pagination__control-link--previous';
      break;
    case 'nextpostslink':
      $class_name = 'pagination__control-link pagination__control-link--next';
      break;
    case 'page':
      $class_name = 'pagination__current'
      break;
  }
  return $class_name;
}
