将自定义 URL 段添加到 wordpress 页面 [英] Add custom URL segment to wordpress page

问题描述

我试图让我的页面接收查询变量，但将其重写为漂亮的永久链接.所以我想要这个

I'm trying to allow my page to receive query variable but to rewrite it to nice permalink. So I wanted this

example.com/wordpress-page/random

所以我不希望 random 成为子页面或类似的东西，因为它来自外部服务.为了做到这一点，我已将此代码添加到我的 functions.php

So I don't want random to be a subpage or something like that, since it's coming from outside service. In order to do this, I've added this code to my functions.php

function add_my_var($public_query_vars) {
    $public_query_vars[] = 'my_var';
    return $public_query_vars;
}

add_filter('query_vars', 'add_my_var');

function do_rewrite() {
    add_rewrite_rule('wordpress-page/([^/]+)/?$', 'index.php?name=wordpress-page&my_var=$matches[1]','top');
}

add_action('init', 'do_rewrite');

当我去 example.com/wordpress-page 时我得到我的页面，但是当我去 example.com/wordpress-page/random 时我得到 404页.

When I go to example.com/wordpress-page I get my page, but when I go to example.com/wordpress-page/random I get 404 page.

我通过在 wp-admin 面板中保存永久链接来刷新重写规则.

I have flushed rewrite rules by saving permalinks in wp-admin panel.

我哪里做错了?

推荐答案

我发现我需要调用 flush_rewrite_rules() 函数.除了上面已经演示的 query_vars 动作挂钩和 add_rewrite_rule() 函数之外，还完成了这项工作.

I found I needed to call the flush_rewrite_rules() function. That was done in addition to the query_vars action hook and add_rewrite_rule() function you already demonstrated above.

在我的例子中，我选择使用 switch_theme 操作将它放在我的主题的functions.php 中挂钩并停用/重新激活我的主题.但是你可以把它放在别处，只要它在某个时候被调用一次(所以可能不是'init')

In my case I chose to put it in my theme's functions.php using the switch_theme action hook and deactivated/reactivated my theme. But you can probably put it elsewhere as long as it get's called once at some point (so probably not 'init')

add_action('switch_theme', 'mytheme_setup_options');

function mytheme_setup_options () {
    flush_rewrite_rules();
}
