使用URL参数进行查询重写

Question

我无法使查询重写按预期工作。期望的结果是将请求wpsite.com/foo/bar/2/重写为wpsite.com/foo/bar/?my_id=2。functions.php// Add custom URL parametersfunction add_custom_query_var( $vars ){  $vars[] = "my_id";  return $vars;}add_filter( 'query_vars', 'add_custom_query_var' );// Add rewrite for my_idfunction custom_rewrite_basic() {    add_rewrite_rule('^foo/bar/([0-9]+)/?', 'foo/bar/?my_id=$matches[1]', 'top');}add_action( 'init', 'custom_rewrite_basic' );bar.php$my_id = filter_input( INPUT_GET, "my_id", FILTER_SANITIZE_NUMBER_INT );var_dump($my_id);当我打电话给/foo/bar/?my_id=2我2时/foo/bar/2/，我看不到。更新刷新缓存后，结果得到了改善。但是，无论传递的参数（3，256205）如何，$my_id都返回为1。wpsite.com/foo/bar/?my_id=2 表演 2wpsite.com/foo/bar/2/ 表演 1

Answer 1

这可以通过更改$matches[1]为来解决$1：

// Add rewrite for my_id

function custom_rewrite_basic() 

{

    add_rewrite_rule('^foo/bar/([0-9]+)/?', 'foo/bar/?my_id=$1', 'top');

}

add_action( 'init', 'custom_rewrite_basic' );

当然还有刷新缓存。
