根据 URL 查询字符串重定向 URL

Question

我想根据自定义帖子类型的 URL 查询字符串重定向 URL。

示例网址：http://example.com/custom_post_type/post-name?et_fb=1

我想检查 URL 是否有查询字符串 ?et_fb=1，如果有，请不要重定向，否则重定向到管理页面。我尝试了以下功能，但它没有将我带到管理 URL

function redirect_cpt_to_admin() {
    $url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
    $redirect = strpos($url,'?et_fb') == false;

    global $wp_query;
    if ( is_singular('my_cpt') && $redirect ){
        $admin_url   = admin_url();
        wp_redirect( esc_url_raw( $admin_url ), 301 );
        exit(); 
}
}
add_action ( 'template_redirect', 'redirect_cpt_to_admin', 20);

试试这个功能：

function my_cpt_template_redirect()
{
   $url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
   $param = 'et_fb';
   $redirect = strpos($url,$param);

   $obj = get_post_type_object( 'YOURCUSTOMPOSTYPE FOR EXAMPLE POST' );

    if( $obj->labels->singular_name == "YOURCUSTOMPOSTYPE_SINGULAR_NAME" && $redirect === true )
    {
        wp_redirect( admin_url());
        exit();
    }
}
add_action( 'template_redirect', 'my_cpt_template_redirect' );

假设我们有帖子类型“认证”，我们可以这样做：

$obj = get_post_type_object( 'certification' );

基本上如果你 print_r($obj)，你会看到下面的结果：

stdClass Object
(
    [labels] => stdClass Object
        (
            [name] => Certification
            [singular_name] => Certification
