之前写过一篇《
WordPress 自动内链关键词》，今天和大家分享wordpress文章的标签内链的方法。
php
/**
* WordPress 文章标签自动链接
*/
function wpkj_auto_add_tag_link($content){
$limit = 1; // 设置同一个标签添加几次链接
$posttags = get_the_tags();
if ($posttags) {
foreach($posttags as $tag) {
$link = get_tag_link($tag->term_id);
$keyword = $tag->name;
$cleankeyword = stripslashes($keyword);
$url = '<a target="_blank" href="/'.$link.'" title="'.str_replace('%s', addcslashes($cleankeyword, '$'), __('View all posts in %s')).'" rel="noopener">'.addcslashes($cleankeyword, '$').'</a>';
$regEx = '\'(?!((<.*?)|(<a.*?)))('. $cleankeyword . ')(?!(([^<>]*?)>)|([^>]*?</a>))\'s';
$content = preg_replace($regEx,$url,$content,$limit);
}
}
return $content;
}
add_filter( 'the_content', 'wpkj_auto_add_tag_link', 1 );
