WordPress的文章归档还是很有必要的,特别是文章多了之后,用归档可以很方便的找到想要找的文章,网上有很多的插件可以实现这个功能,不过我们喜欢折腾,那么就不用插件,而是使用代码来实现。
如果在配合Jquery的话,可以实现非常棒的效果。
下面我就说下简单的操作方法。
1、把下面的 archives_list_SHe 函数代码添加到主题的 functions.php 里面;
function archives_list_SHe() { global $wpdb,$month; $lastpost = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_date <'" . current_time('mysql') . "' AND post_status='publish' AND post_type='post' AND post_password='' ORDER BY post_date DESC LIMIT 1"); $output = get_option('SHe_archives_'.$lastpost); if(empty($output)){ $output = ''; $wpdb->query("DELETE FROM $wpdb->options WHERE option_name LIKE 'SHe_archives_%'"); $q = "SELECT DISTINCT YEAR(post_date) AS year, MONTH(post_date) AS month, count(ID) as posts FROM $wpdb->posts p WHERE post_date <'" . current_time('mysql') . "' AND post_status='publish' AND post_type='post' AND post_password='' GROUP BY YEAR(post_date), MONTH(post_date) ORDER BY post_date DESC"; $monthresults = $wpdb->get_results($q); if ($monthresults) { foreach ($monthresults as $monthresult) { $thismonth = zeroise($monthresult->month, 2); $thisyear = $monthresult->year; $q = "SELECT ID, post_date, post_title, comment_count FROM $wpdb->posts p WHERE post_date LIKE '$thisyear-$thismonth-%' AND post_date AND post_status='publish' AND post_type='post' AND post_password='' ORDER BY post_date DESC"; $postresults = $wpdb->get_results($q); if ($postresults) { $text = sprintf('%s %d', $month[zeroise($monthresult->month,2)], $monthresult->year); $postcount = count($postresults); $output .= '<ul class="archives-list"><li><span class="archives-yearmonth">' . $text . ' (' . count($postresults) . ' 篇文章)</span><ul class="archives-monthlisting">' . "\n"; foreach ($postresults as $postresult) { if ($postresult->post_date != '0000-00-00 00:00:00') { $url = get_permalink($postresult->ID); $arc_title = $postresult->post_title; if ($arc_title) $text = wptexturize(strip_tags($arc_title)); else $text = $postresult->ID; $title_text = 'View this post, "' . wp_specialchars($text, 1) . '"'; $output .= '<li>' . mysql2date('d日', $postresult->post_date) . ': ' . "<a href='$url' title='$title_text'>$text</a>"; $output .= ' (' . $postresult->comment_count . ')'; $output .= '</li>' . "\n"; } } } $output .= '</ul></li></ul>' . "\n"; } update_option('SHe_archives_'.$lastpost,$output); }else{ $output = '<div class="errorbox">Sorry, no posts matched your criteria.</div>' . "\n"; } } echo $output; }
2、复制一份主题的 page.php 更名为 archives.php,然后在最顶端加入:
<?php /* Template Name: archives */ ?>
3、再然后找到类似 ,在其下面加入如下代码
<a id="expand_collapse" href="#">全部展开/收缩</a> <div id="archives"><?php archives_list_SHe(); ?></div>
进wp后台添加一新页面,在右侧栏模板选择 archives。
4、如果你的主题本身加载了 jQuery 库,那么继续把下面的 jQ 代码加上去,就会有滑动伸缩效果了。
<script type="text/javascript"> jQuery(document).ready(function() { $('#expand_collapse,.archives-yearmonth').css({cursor:"s-resize"}); $('#archives ul li ul.archives-monthlisting').hide(); $('#archives ul li ul.archives-monthlisting:first').show(); $('#archives ul li span.archives-yearmonth').click(function(){$(this).next().slideToggle('fast');return false;}); $('#expand_collapse').toggle( function(){ $('#archives ul li ul.archives-monthlisting').slideDown('fast'); }, function(){ $('#archives ul li ul.archives-monthlisting').slideUp('fast'); }); }); </script>
css 样式可以通过 #archive 来定义,ok,搞定。
