wp_redirect ( $location, $status = 302, $x_redirect_by = 'WordPress' )
wp_redirect: 这个函数用于将用户重定向到一个新的页面或URL。它向用户的浏览器发送一个HTTP头以触发重定向。
重定向到另一个页面。
注意:wp_redirect()不会自动退出,几乎总是应该在后面调用`exit;`。
wp_redirect( $url );
exit;
通过使用wp_redirect()作为条件与{@see ‘wp_redirect’}和{@see ‘wp_redirect_location’}过滤器一起使用,也可以有选择地操作退出:
if ( wp_redirect( $url ) ) {
exit;
}
