WordPress功能还是比较强大的，WordPress可以进行自定义文章类型功能，可以有内容，有评论，有点赞，只是因为很多文章用到的内容用不上导致浪费，对数据库不是很友好，那么WordPress如何自定义实现问答效果？

只需使用wordpress提供的register_post_type函数即可实现。将上面的代码放在你的functions.php文件中，到wordpress后台就能看见一个名为问答的一级菜单了，其形式如文章菜单。
此时是否再访问可能会出现404未找到的现象，因此我们在代码中定义了此问答类型文章的访问路径，涉及到伪静态的，需要前往后台——设置——固定链接保存一下。
此时应该就能正确显示问答类型文章的页面了，就是你上面保存的那个HTML。只需对其进行一些动态替换即可完成内容的自动变换。
重写自定义文章类型文章的URL规则
如果我们希望问答类型文章的访问路径为：域名/question/postid.html，那么在functions.php文件中添加如下url重写规则。

//重写自定义文章类型url规则
add_filter(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’post_type_link\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’custom_question_answer_link\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, 1, 3);
function custom_question_answer_link( $link, $post = 0 ){
if ( $post->post_type == \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’question_answer\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ ){
return home_url( \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’question/\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ . $post->ID .\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’.html\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ );
} else {
return $link;
}
}
add_action( \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’init\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’custom_question_answer_rewrites_init\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ );
function custom_question_answer_rewrites_init(){
add_rewrite_rule(
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’question/([0-9]+)?.html$\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’index.php?post_type=question_answer&p=$matches[1]\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’top\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ );
add_rewrite_rule(
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’question/([0-9]+)?.html/comment-page-([0-9]{1,})$\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’index.php?post_type=question_answer&p=$matches[1]&cpage=$matches[2]\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’top\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’
);
}
再次保存一下动态链接试试效果吧。
创建单独数据表实现问答效果
这种效果是我认为最好的，因为可以高度自定义，不拘泥于wordpress，但代码量相对较大，对数据表的设计能力有一定要求，后期维护也比较复杂。建议最少能自己独立完成数据表的增删改查的站长使用，并且此种方式在wordpress后台管理不如第一种方式快捷方便。
虽然第二种比较复杂，但让我选，我仍然选第二种。最大的原因是预估本站数据会越来越大，wordpress的自定义文章类型实在太过臃肿，数据量大了后期网站速度影响较大。
