Radyo düğmesi veya seçilen açılan listesinde bağlı PHP form yönlendirmeyi nasıl değiştirilir?

1 Cevap php

The idea is to be able to perform some search query depending on radio button selected or drop-down choice. I know my PHP code is wrong, that's why I need your help ;-)

Radyo düğmeleri ile benim eski sürümü sadece gibi olabilir test here (click) çalışıyor.

-S: Ama ben açılır liste ile bunu nasıl anlamaya olamaz

Cevaplar için teşekkürler.

Not: W3C XHTML olmalı Sıkı uyumlu ve working when JavaScript is disabled (bu radyo düğmesini tek sürümü için önceden olduğu gibi).

Sen metin girişi, radyo grubu için aynı ad özniteliği ve seçme-seçenek grubu kullanamazsınız.

Farklı isimler ile aralarına ve sonra her durumda işlemek için birden conditionals kullanmayı deneyin.

Örnek:

switch ($_REQUEST['radio_group']) 
{
    case 'google':
        ... look for $_REQUEST['google_lang_dropdown'] ... 
    break;
    case 'bing':
        .. do something..
    break;
    case 'wikipedia':
        ... look for $_REQUEST['wikipedia_lang_dropdown'] ... 
    break;

}
