使用干净的URL将参数传递到自定义页面模板


8

我现在将参数传递给以下格式的自定义模板

www.example.com/?pageid=12&rid=24&title=this-is-the-title

我创建了两个表。因此,我需要获取数据并在这些页面上显示它们。

我希望它使用干净的URL格式,例如:

www.example.com/pageid/12/rid/24/title/this-is-the-title

谁能说出这是如何实现的?

谢谢


完全有可能,但您必须注意可变的段塞,以避免冲突。看看这篇文章对WordPress的抄本......这可能是你想使用挂钩,它显示了一个样本改写阵列... codex.wordpress.org/Plugin_API/Filter_Reference/...

add_rewrite_rule() 允许您将漂亮的网址转换为变量。

  • 数字: (\d*)
  • 部分: /rid//pageid/
  • ug: ([a-zA-Z0-9-]+

如果发现匹配项,这是一个注册重写并处理请求的类。

<?php

if ( ! class_exists( 'CPTURLRewrite' ) ):

    class CPTURLRewrite {
        const ENDPOINT_QUERY_NAME  = 'pageid';
        const ENDPOINT_QUERY_PARAM = '__pageid';

        // WordPress hooks

        public function init() {
            add_filter( 'query_vars', array ( $this, 'add_query_vars' ), 0 );
            add_action( 'parse_request', array ( $this, 'sniff_requests' ), 0 );
            add_action( 'init', array ( $this, 'add_endpoint' ), 0 );
        }

        // Add public query vars

        public function add_query_vars( $vars ) {

            // add all the things we know we'll use

            $vars[] = static::ENDPOINT_QUERY_PARAM;
            $vars[] = 'pageid';
            $vars[] = 'rid';
            $vars[] = 'title';

            return $vars;
        }

        // Add API Endpoint

        public function add_endpoint() {

            // numbers:   (\d*)
            // section:   /rid/
            // slug:      ([a-zA-Z0-9-]+

            add_rewrite_rule( '^' . static::ENDPOINT_QUERY_NAME . '/(\d*)/rid/(\d*)/title/([a-zA-Z0-9-]+)?', 'index.php?' . static::ENDPOINT_QUERY_PARAM . '=1&pageid=$matches[1]&rid=$matches[2]&title=$matches[3]', 'top' );

            //////////////////////////////////
            flush_rewrite_rules( false ); //// <---------- REMOVE THIS WHEN DONE
            //////////////////////////////////
        }

        // Sniff Requests

        public function sniff_requests( $wp_query ) {
            global $wp;

            if ( isset(
                $wp->query_vars[ static::ENDPOINT_QUERY_PARAM ],
                $wp->query_vars[ 'pageid' ],
                $wp->query_vars[ 'rid' ],
                $wp->query_vars[ 'title' ] ) ) {
                $this->handle_request(); // handle it
            }
        }

        // Handle Requests

        protected function handle_request() {
            global $wp;

            // (optional) act on the query vars

            $pageid = $wp->query_vars[ 'pageid' ];
            $rid = $wp->query_vars[ 'rid' ];
            $title = $wp->query_vars[ 'title' ];

            // (optional) select your custom template

            add_filter( 'template_include', function( $original_template ) {
                return __DIR__ . '/custom.php';
            } );
        }
    }

    $wpCPTURLRewrite = new CPTURLRewrite();
    $wpCPTURLRewrite->init();

endif; // CPTURLRewrite

更新

我找到了一种更简单的方法来处理此问题。

http://example.com/pageid/333/rid/444/title/your-title-此处/

这种新方法利用add_rewrite_tagwith _来运行页面ID的查询,而不会弄乱主查询。在上面的示例中,333只需修改查询以在中查找该帖子ID pre_get_posts。您可以轻松地修改template_redirecttemplate_include

/**
 * Register a rewrite endpoint for the API.
 */
function prefix__init() {

    // add tags with `_` prefix to avoid screwing up query
    add_rewrite_tag( '%_pageid%', '(\d*)' );
    add_rewrite_tag( '%_rid%', '(\d*)' );
    add_rewrite_tag( '%_title%', '([a-zA-Z\d\-_+]+)' );

    // create URL rewrite
    add_rewrite_rule( '^pageid/(\d*)/rid/(\d*)/title/([a-zA-Z\d\-_+]+)?', 'index.php?_pageid=$matches[1]&_rid=$matches[2]&_title=$matches[3]', 'top' );

    // required once after rules added/changed
    // flush_rewrite_rules( true );
}

add_action( 'init', 'prefix__init' );

/**
 * Handle data (maybe) passed to the API endpoint.
 *
 * @param $query
 */
function prefix__pre_get_posts( $query ) {

    if ( isset( $query->query_vars[ '_pageid' ], $query->query_vars[ '_rid' ], $query->query_vars[ '_title' ] ) ) {

        // set the query to search for a page using `_pageid`
        $query->set( 'p', $query->query_vars[ '_pageid' ] );
    }
}

add_action( 'pre_get_posts', 'prefix__pre_get_posts' );

要引用稍后传递的所有参数:

/**
* Debug the query params at any point
*/
function prefix__show_query_args() {
 global $wp_query;

    echo "<pre>";
    print_r( array (
        'pageid' => $wp_query->query_vars[ '_pageid' ],
        'rid'    => $wp_query->query_vars[ '_rid' ],
        'title'  => $wp_query->query_vars[ '_title' ],
        'file'   => __FILE__,
        'line'   => __LINE__,
    ) );
    echo "</pre>";
}

如果您想要一个简单的解决方案,可能就是它(没有测试过代码,因此如果它不起作用,可能就不会那么简单...)或至少给出了一些提示,您需要做些什么。如果您访问http://thereforei.am/2011/10/28/advanced-taxonomy-queries-with-pretty-urls/,则会发现额外的奖励:文章中的重写规则生成器。我以前曾使用过此功能,但在这种情况下并未使用过。尝试将该功能与以下内容结合起来:

add_rewrite_tag('%pageid%','([^&]+)');
add_rewrite_tag('%rid%','([^&]+)');
add_rewrite_tag('%title%','([^&]+)');

/* Generate rewrite rules. */
add_action( 'generate_rewrite_rules', 'example_add_rewrite_rules' );
function example_add_rewrite_rules() {
    global $wp_rewrite;
    $new_rules = eg_generate_rewrite_rules( 'post' , array('pageid','rid','title')); //    post = the post type you use
    $wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
}

/* Flush rewrite rules on theme activation only. */
add_action( 'load-themes.php', 'frosty_flush_rewrite_rules' );
function frosty_flush_rewrite_rules() {
    global $pagenow;
    if ( 'themes.php' == $pagenow && isset( $_GET['activated'] ) )
        flush_rewrite_rules();
}

如果您不想使用eg_generate_rewrite_rules函数,则需要自己设置规则。您可以在该文章中找到有关如何执行此操作的信息。
