News Manager

[darkblue]

A further change I have made on my weblog (News Manager) at https://www.perpetual-beta.org/ is to have proper previous and next buttons at the end of each post, in place of the JavaScript "back" link that the News Manager uses by default.

In the file /plugins/news_manager/inc/site.php, find the function called "nm_show_post" and replace the following:

Code:

# show "go back" link, if required
if (strstr($_SERVER['QUERY_STRING'], "post=$slug")) {
echo '<p class="nm_post_back"><a href="javascript:history.back()">&lt;&lt; ';
i18n('news_manager/GO_BACK');
echo '</a></p>';
}

with:

Code:

// BOF: Previous & Next article links
if ( !$excerpt && ($post->private != 'Y') ) {
    echo '<div id="pagerBottom">';
    $articleIndex = nm_get_posts();
    $articleDirectory = array();
    foreach ($articleIndex as $article) $articleDirectory[strtotime($article->date)] = $article->title . '|' . nm_get_url('post') . $article->slug;
    unset($articleIndex);
    ksort($articleDirectory);

    $current = strtotime($post->date);
    reset($articleDirectory);
    while (key($articleDirectory) !== $current) next($articleDirectory);

    prev($articleDirectory);
    $previous = key($articleDirectory);
    if ( ($previous !== $current) && $previous ) {
        $prevTemp = explode('|', $articleDirectory[$previous]);
        echo '<div class="prevLink"><a href="' . $prevTemp[1] . '" title="read: ' . $prevTemp[0] . ' (dated: ' . date('l jS \of F Y h:i:s A', $previous) . ')"><span class="button">&larr; Previous Post</span></a></div>';
        next($articleDirectory);
    } elseif (!$previous) {
        reset($articleDirectory);
    }

    next($articleDirectory);
    $next = key($articleDirectory);
    if ( ($next !== $current) && $next ){
        $nextTemp = explode('|', $articleDirectory[$next]);
        echo '<div class="nextLink"><a href="' . $nextTemp[1] . '" title="read: ' . $nextTemp[0] . ' (dated: ' . date('l jS \of F Y h:i:s A', $next) . ')"><span class="button">Next Post &rarr;</span></a></div>';
    }
    unset($articleDirectory);
    echo '</div>';
}
// EOF: Previous & Next article links

Have fun!
