Do you want link your article with the previous and the next article in Drupal 7?
Put the following code in your template.php of your theme:
<?php/** * Gets the context nodes: start, prev, next and last. * @param $variables * start, prev, next and last will be added. Passed by reference. * @param $texts * array with start, prev, next and last * having keys dominant_text, prepend_text and append_text * @return * $variables with new values * * Reference: http://drupal.org/node/37767. */function YOUR_THEME_context_nodes($node, &$variables, $texts = array()) { $query = "(SELECT 'prev' as id, n.nid, n.title FROM {node} n WHERE " . 'n.created < :created AND n.type = :type AND n.status = 1 ' . "AND language IN (:lang, 'und') " . 'ORDER BY n.created DESC LIMIT 1) '; $query .= ' UNION ' . "(SELECT 'next' as id, n.nid, n.title FROM {node} n WHERE " . 'n.created > :created AND n.type = :type AND n.status = 1 ' . "AND language IN (:lang, 'und') " . 'ORDER BY n.created ASC LIMIT 1)'; $query .= ' UNION ' . "(SELECT 'start' as id, n.nid, n.title FROM {node} n WHERE " . 'n.type = :type AND n.status = 1 ' . "AND language IN (:lang, 'und') " . 'ORDER BY n.created ASC LIMIT 1)'; $query .= ' UNION ' . "(SELECT 'last' as id, n.nid, n.title FROM {node} n WHERE " . 'n.type = :type AND n.status = 1 ' . "AND language IN (:lang, 'und') " . 'ORDER BY n.created DESC LIMIT 1)'; $rows = db_query($query, array(':created' => $node->created, ':type' => $node->type, ':lang' => $node->language)); foreach ($rows as $row) { drupal_add_html_head_link(array( 'rel' => $row->id, 'type' => 'text/html', 'title' => $row->title, 'href' => url('node/' . $row->nid, array('absolute' => FALSE)), )); if (isset($texts[$row->id])) { $text = !empty($texts[$row->id]['dominant_text']) ? t($texts[$row->id]['dominant_text']) : $row->title; $variables[$row->id] = (!empty($texts[$row->id]['prepend_text']) ? t($texts[$row->id]['prepend_text']) : '') . l($text, 'node/' . $row->nid, array('attributes' => array('rel' => array($row->id)))) . (!empty($texts[$row->id]['append_text']) ? t($texts[$row->id]['append_text']) : ''); } } return $variables;}?>
Put the following code in your template.php of your theme:
<?phpfunction YOUR_THEME_preprocess_node(&$variables) { YOUR_THEME_context_nodes($node, $variables, array( 'start' => array('dominant_text' => '« First article'), 'prev' => array('dominant_text' => '‹ Previous article'), 'next' => array('dominant_text' => 'Next article' ›'), 'last' => array('dominant_text' => 'Latest article' »'), ));?>
Finally, you can output your links in your node.tpl.php of your theme:
<?php if ($page && (isset($prev) || isset($next))): ?>
<div id="prev-next" class="prev-next clearfix">
<?php if (isset($prev)): ?>
<div class="prev">
<?php print $prev; ?>
</div>
<?php endif; ?>
<?php if (isset($next)): ?>
<div class="next">
<?php print $next; ?>
</div>
<?php endif; ?>
</div>
<?php endif; ?>
