WordPress如何自定义首字母排序标签页面？制作一个首字母排序的标签页面，通过代码实现所有站内标签按照26个字母进行分类排序。中文按首字母排列标签云有些麻烦，我们必须检索出标签第一个字的拼音的第一个字母，然后进行排序输出。提供用户体验，具体效果如图：

1、第一步

把下面汉字转字母类放到 functions.php最后一个 ?>

/**

class Chinese_to_PY {

/**

* 拼音字符转换图

* @var array

);

/**

* 将中文编码成拼音

* @param string $chinese 要转换为拼音的字符串

* @param string $sRetFormat 返回格式 [first:每个字的首字母|all:全拼音|one:字符串字母]

* @return string

*/

public static function getPY($chinese, $sRetFormat=’first’){

$sGBK = iconv(‘UTF-8’, ‘GBK’, $chinese);

$sUTF8 = iconv(‘GBK’, ‘UTF-8’, $sGBK);

if($sUTF8 != $chinese) $sGBK = $chinese;

$aBuf = array();

for ($i=0, $iLoop=strlen($sGBK); $i<$iLoop; $i++) {

$iChr = ord($sGBK{$i});

if ($iChr>160)

$iChr = ($iChr<<8) + ord($sGBK{++$i}) – 65536;

if (‘first’ == $sRetFormat || ‘one’ == $sRetFormat)

$aBuf[] = substr(self::zh2py($iChr),0,1);

else

$aBuf[] = self::zh2py($iChr);

}

if (‘first’ === $sRetFormat)

return implode(”, $aBuf);

elseif(‘one’ == $sRetFormat)

return $aBuf[0];

else

return implode(‘ ‘, $aBuf);

}

/**

* 中文转换到拼音(每次处理一个字符)

* @param number $iWORD 待处理字符双字节

* @return string 拼音

*/

private static function zh2py($iWORD) {

if($iWORD>0 && $iWORD<160 ) {

return chr($iWORD);

} elseif ($iWORD<-20319||$iWORD>-10247) {

return ”;

} else {

foreach (self::$_aMaps as $py => $code) {

if($code > $iWORD) break;

$result = $py;

}

return $result;

}

}

}

2、第二步

接着就是获取所有标签生成标签页的代码（依然放入主题functions.php函数文件中）：

function specs_show_tags() {

if(!$output = get_option(‘specs_tags_list’)){

$categories = get_terms( ‘post_tag’, array(

‘orderby’ => ‘count’,

‘hide_empty’ => 1

) );

$r = array();

foreach($categories 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);

$output = “<ul class=’list-inline’ id=’tag_letter’>”;

for($i=65;$i<=90;$i++){

$tagi = $r[chr($i)];

if(is_array($tagi)){

$output .= “<li><a href=’#”.chr($i).”‘>”.chr($i).”</a></li>”;

}else{

$output .= “<li>”.chr($i).”</li>”;

}

}

for($i=48;$i<=57;$i++){

$tagi = $r[chr($i)];

if(is_array($tagi)){

$output .= “<li><a href=’#”.chr($i).”‘>”.chr($i).”</a></li>”;

}else{

$output .= “<li>”.chr($i).”</li>”;

}

}

$output .= “</ul>”;

$output .= “<ul id=’all_tags’ class=’list-unstyled’>”;

for($i=65;$i<=90;$i++){

$tagi = $r[chr($i)];

if(is_array($tagi)){

$output .= “<li id=’”.chr($i).”‘><h4 class=’tag_name’>”.chr($i).”</h4>”;

foreach($tagi as $tag){

$output .= “<a href=’”.get_tag_link($tag->term_id).”‘>”.$tag->name.”(“.$tag->count.”)</a>”;

}

}

}

for($i=48;$i<=57;$i++){

$tagi = $r[chr($i)];

if(is_array($tagi)){

$output .= “<li id=’”.chr($i).”‘><h4 class=’tag_name’>”.chr($i).”</h4>”;

foreach($tagi as $tag){

$output .= “<a href=’”.get_tag_link($tag->term_id).”‘>”.$tag->name.”(“.$tag->count.”)</a>”;

}

}

}

$output .= “</ul>”;

update_option(‘specs_tags_list’, $output);

}

echo $output;

}

function clear_tags_cache() {

update_option(‘specs_tags_list’, ”); // 清空 specs_archives_list

}

add_action(‘save_post’, ‘clear_tags_cache’); // 新发表文章/修改文章时

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。

3、第三步

之后效果都可以自己选择，在css哪里设置，下面是上面的图片一样效果的代码例子：

.tag_name{ width:1034px; float:left; line-height:30px; margin:25px 0 0 26px; font-size:14px; color:#000;line-height: 200%;}

.tag_name_a{ width:1034px; float:left; border:2px solid #d8d9d9;}

.tag_name_b{ width:680px; float:left; line-height:30px; margin:25px 0 0 26px; font-size:14px; color:#000;}

.tag_name_c{ width:980px; height:45px; float:left; border-bottom:1px solid #d8d9d9; margin:25px 0 0 26px; font-size:20px; color:#000;}

.list-unstyled{ width:1034px; float:left; line-height:30px; margin:25px 0 0 26px; font-size:14px; color:#000;line-height: 200%;margin: 2px;}

.list-unstyled li{width: 1000px;float: left;margin: 0 10px 0 0;padding: 5px;}

.list-unstyled a{color: #333333; padding: 5px 8px;}

.list-inline {width:1000px;list-style: none;height:100px; text-align:center; overflow:hidden; padding-top:0em;}

.list-inline li{float: left;}

.list-inline a{display: block;text-decoration: none;background: none repeat scroll 0 0 #333333; border: 5px solid #333333; color: #f7f8f8; margin: 1px; padding: 3px 8px;}

.list-inline a:hover,.ist-inlin a.current {text-decoration: underline;background: none repeat scroll 0 0 #da5a04; border: 4px solid #da5a04;

color: #f7f8f8; font-weight: bolder;}
