带有额外查询变量var

的搜索结果相当固定

我想知道如何使用wp_redirect和template_redirect钩子将还包含额外查询变量的搜索URL重写为漂亮的永久链接.

我从 Nice Search 插件中获取了代码,该插件可以很好地更改http://example.com?s=africa放入http://example.com/search/africa:

 add_action( 'template_redirect', 'my_rewrite' ) );

function my_rewrite() {

        if ( is_search() and false === strpos( $_SERVER['REQUEST_URI'], '/search/' ) ) {
            wp_redirect( get_bloginfo( 'home' ) . '/search/' . str_replace( ' ', '+', str_replace( '%20', '+', get_query_var( 's' ) ) ) );
            exit();
        }

    }

但是我将选择下拉菜单与 Relevanssi 插件结合使用,以允许访问者将搜索范围缩小到特定的帖子类型.这会添加一个post_type查询变量,例如http://example.com?s=africa&post_type=features.我希望它具有类似http://example.com/search/africa/section/features的URL.

Nice Search代码导致post_type查询var丢失.所以我尝试了以下代码:

 function my_rewrite() {

    if ( is_search() and false === strpos( $_SERVER['REQUEST_URI'], '/search/' ) ) {
        if ( isset( $_GET['post_type'] ) and '' !== $_GET['post_type'] ) {
            wp_redirect( get_bloginfo( 'home' ) . '/search/' . str_replace( ' ', '+', str_replace( '%20', '+', get_query_var( 's' ) ) ) . '/section/' . str_replace( ' ', '+', str_replace( '%20', '+', get_query_var( 'post_type' ) ) ) );
        } else {
            wp_redirect( get_bloginfo( 'home' ) . '/search/' . str_replace( ' ', '+', str_replace( '%20', '+', get_query_var( 's' ) ) ) );
        }
        exit();
    }

}

但是WordPress现在认为搜索词是africa/section/features.

有没有办法使搜索字词和查询var都保持在一个很好的永久链接中?

谢谢西蒙

I'd like to know how I can rewrite a search URL that also contains an extra query var into a pretty permalink using wp_redirect and the template_redirect hook.

I have taken the code from the Nice Search plugin which works fine to change http://example.com?s=africa into http://example.com/search/africa:

add_action( 'template_redirect', 'my_rewrite' ) );

function my_rewrite() {

        if ( is_search() and false === strpos( $_SERVER['REQUEST_URI'], '/search/' ) ) {
            wp_redirect( get_bloginfo( 'home' ) . '/search/' . str_replace( ' ', '+', str_replace( '%20', '+', get_query_var( 's' ) ) ) );
            exit();
        }

    }

But I am using a select dropdown in combination with the Relevanssi plugin to allow visitors to narrow down the search to a particular post type. This adds a post_type query var, e.g. http://example.com?s=africa&post_type=features. I would like this to have a URL something like http://example.com/search/africa/section/features.

The Nice Search code causes the post_type query var to be lost. So I tried the following code:

function my_rewrite() {

    if ( is_search() and false === strpos( $_SERVER['REQUEST_URI'], '/search/' ) ) {
        if ( isset( $_GET['post_type'] ) and '' !== $_GET['post_type'] ) {
            wp_redirect( get_bloginfo( 'home' ) . '/search/' . str_replace( ' ', '+', str_replace( '%20', '+', get_query_var( 's' ) ) ) . '/section/' . str_replace( ' ', '+', str_replace( '%20', '+', get_query_var( 'post_type' ) ) ) );
        } else {
            wp_redirect( get_bloginfo( 'home' ) . '/search/' . str_replace( ' ', '+', str_replace( '%20', '+', get_query_var( 's' ) ) ) );
        }
        exit();
    }

}

but WordPress now thinks the search term is africa/section/features.

Is there a way I can keep the search term and the query var all in a nice permalink?

Thanks Simon

要修改搜索重写规则,您可以插入search_rewrite_rules过滤器.您可以自己添加与帖子类型匹配的额外重写规则,也可以更改默认的"搜索重写结构"以包含帖子类型,然后重新生成规则(有四个规则:一个标准,一个带有分页的规则和两个供稿).因为WP_Rewrite::generate_rewrite_rules() 在每个"目录级别"生成规则,您将获得/search/[keyword]/section/[post_type]/,/search/[keyword]/section/和/search/[keyword]/.您不需要中间规则,但是保持中间规则也不会受到伤害.

 add_filter( 'search_rewrite_rules', 'wpse15418_search_rewrite_rules' );
function wpse15418_search_rewrite_rules( $search_rewrite_rules )
{
    global $wp_rewrite;
    $wp_rewrite->add_rewrite_tag( '%post_type%', '([^/]+)', 'post_type=' );
    $search_structure = $wp_rewrite->get_search_permastruct();
    return $wp_rewrite->generate_rewrite_rules( $search_structure . '/section/%post_type%', EP_SEARCH );
}

要查看规则,请使用我的重写分析器插件.

To modify the search rewrite rules you can hook into the search_rewrite_rules filter. You can either add the extra rewrite rules that match post types yourself, or you can change the default "search rewrite structure" to also include the post type and then re-generate the rules (there are four rules: one standard, one with paging and two for feeds). Because WP_Rewrite::generate_rewrite_rules() generates rules at every "directory level", you will get rules for /search/[keyword]/section/[post_type]/, /search/[keyword]/section/ and /search/[keyword]/. You don't need the middle rule, but it won't hurt to keep it in.

add_filter( 'search_rewrite_rules', 'wpse15418_search_rewrite_rules' );
function wpse15418_search_rewrite_rules( $search_rewrite_rules )
{
    global $wp_rewrite;
    $wp_rewrite->add_rewrite_tag( '%post_type%', '([^/]+)', 'post_type=' );
    $search_structure = $wp_rewrite->get_search_permastruct();
    return $wp_rewrite->generate_rewrite_rules( $search_structure . '/section/%post_type%', EP_SEARCH );
}

To check the rules, use my Rewrite analyzer plugin.
