制作一个按标签首字母分类的WordPress标签页

| WordPress | 29 条评论 | (10评) |

前些天看到有些人的博客里有个标签页，把所有标签列出来，然后按标题首字母分类。当时留言问了下方法，但是并没有给我回复，所以就想自己来做一下，自己动手丰衣足食嘛。最后终于是做出来了，虽然可能别人的方法比我的简单，但总算是能够实现的一种吧，具体效果可以查看《标签页》。

已升级方法，添加了缓存，请查看：《升级版》

制作这个页面其中有一点是比较重要的，就是字符串的首字母，这个的方法我在前面已经分享过了，具体可以查看 这里。

代码

首先，把下面汉字转字母类放到 functions.php最后一个 ?> 之前

<?php
/**
 * 汉字转拼音类
 * Author: Specs
 * Homepage: https://9iphp.com
 */
class Chinese_to_PY {
    /**
     * 拼音字符转换图
     * @var array
     */
    private static $_aMaps = array(
        'a'=>-20319,'ai'=>-20317,'an'=>-20304,'ang'=>-20295,'ao'=>-20292,

/**

function specs_show_tags() {
	global $wpdb;

	$query .= " LEFT JOIN $wpdb->term_taxonomy ON $wpdb->term_taxonomy.term_id = $wpdb->terms.term_id ";
	$query .= " WHERE $wpdb->term_taxonomy.taxonomy = 'post_tag' ";
	$query .= " ORDER BY term_id asc";
    //echo $query;
	$categories = $wpdb->get_results($query);
    $r = array();
    foreach($categoryies as $v){
        for($i = 65; $i <= 90; $i++){
            if(strtoupper(Chinese_to_PY::getPY($v->name,'one')) == chr($i)){
                $r[chr($i)][] = $v;
            }
        }
        for($i=48;$i<=57;$i++){
            if(strtoupper(Chinese_to_PY::getPY($v->name,'one')) == chr($i)){
                $r[chr($i)][] = $v;
            }
        }
    }
    ksort($r);
    //print_r($r);
    echo "<ul class='list-inline' id='tag_letter'>";
    for($i=65;$i<=90;$i++){
        echo "<li><a href='#".chr($i)."'>".chr($i)."</a></li>";
    }
    for($i=48;$i<=57;$i++){
        echo "<li><a href='#".chr($i)."'>".chr($i)."</a></li>";
    }
    echo "</ul>";
    echo "<ul id='all_tags' class='list-unstyled'>";
    for($i=65;$i<=90;$i++){
        $tagi = $r[chr($i)];
        if(is_array($tagi)){
            echo "<li id='".chr($i)."'><h4 class='tag_name'>".chr($i)."</h4>";
            foreach($tagi as $tag){
                echo "<a href='".get_tag_link($tag->term_id)."'>".$tag->name."(".specs_post_count_by_tag($tag->term_id).")</a>";
            }
        }
    }
    for($i=48;$i<=57;$i++){
        $tagi = $r[chr($i)];
        if(is_array($tagi)){
            echo "<li id='".chr($i)."'><h4 class='tag_name'>".chr($i)."</h4>";
            foreach($tagi as $tag){
                echo "<a href='".get_tag_link($tag->term_id)."'>".$tag->name."(".specs_post_count_by_tag($tag->term_id).")</a>";
            }
        }
    }
    echo "</ul>";
}
/**
 * 9IPHP <Get post count by tag term_id> in the theme.
 * 根据标签ID活动标签文章数
 */
function specs_post_count_by_tag ( $arg ,$type = 'include'){
    $args=array(
        $type => $arg,
    );
    $tags = get_tags($args);
    if ($tags) {
        foreach ($tags as $tag) {
            return $tag->count;
        }
    }
}

然后复制一份 page.php 文件，把其中 <?php the_content(); ?> 部分换成 <?php specs_show_tags(); ?>，并把 Template Name 名字替换为“标签页面”，然后在后台新建一个页面，模板选择“标签页面”，保存即可。

2014.07.08：更新了版本，对数据进行了缓存，并修改了一些其他方面，请查看《制作一个按标签首字母分类的Wordpress标签页（升级版）》。

2015.05.06：替换了原来的汉字转字母方法。

            @ Specs 搞定，css也弄好了，感谢。我知道刚开始删除对了前台显示不出来是是因为有缓存的问题，隔断时间刷新就OK了。

    我的网站作者比较多，我想做一个按作者首字母的排序，不知要怎么做才好，能帮个忙不？

      @ 晕菜 一样的吧，用取首字母的方法

    呃，确实很多字都没办法正确的显示。上面说的“谢”就不说了，还有“皤”啊，“溧”啊……我觉得应该是因为GBK转UTF-8的问题吧。
