add_rewrite_rule() permite transformar o URL bonito em variáveis.
- números:
(\d*)
- seção:
/rid/ou/pageid/
- lesma:
([a-zA-Z0-9-]+
Aqui está uma classe para registrar a reescrita e manipular a solicitação se uma correspondência for encontrada.
<?php
if ( ! class_exists( 'CPTURLRewrite' ) ):
class CPTURLRewrite {
const ENDPOINT_QUERY_NAME = 'pageid';
const ENDPOINT_QUERY_PARAM = '__pageid';
// WordPress hooks

add_filter( 'query_vars', array ( $this, 'add_query_vars' ), 0 );

add_action( 'init', array ( $this, 'add_endpoint' ), 0 );

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

return $vars;

ATUALIZAR
Eu encontrei uma maneira mais simples de lidar com isso.
http://example.com/pageid/333/rid/444/title/your-title-here/
Essa nova maneira utiliza add_rewrite_tagwith _para executar a consulta para o ID de uma página sem atrapalhar a consulta principal. No exemplo acima, 333apenas modificaria a consulta para procurar esse ID da postagem pre_get_posts. Você poderia facilmente modificar template_redirectou template_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' );
Para fazer referência a todos os parâmetros passados posteriormente:
/**
* 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>";
}
