基于URL查询字符串重定向URL

Question

我想基于URL查询字符串为自定义帖子类型重定向URL。

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

我想检查网址是否包含查询字符串？et_fb = 1 ，如果是，请不要重定向，否则重定向到管理页面。我尝试使用以下功能，但它不会将我带到管理员网址

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);

尝试此功能：

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＆＃39;认证＆＃39;，我们可以这样做：

$obj = get_post_type_object( 'certification' );

基本上如果你print_r（$ obj），你会看到以下结果：

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

我希望它能解决你的问题。随意根据需要和想要完善功能。
