Skrivene kontrole omogucavaju da na web stranicama imate skrivene podatke, sto je korisno ako zelite da imate podatke o korisniku, a korisnik ne dozvoljava upotrebu kolacica.
Primer: u skrivenoj kontroli sa imenom "skriveni_podatak" stavicemo tekst "Zdravo iz Beograda.".

<input name="skriveni_podatak" type="hidden" value="Zdravo iz Beograda.">
<input name="pogledajte" type="submit" Value="Pogledajte"/>
</form>
</body>
</html>

Objasnjenje: podaci koji se nalaze u skrivenoj kontroli nisu vidljivi, ali kada korisnik klikne dugme, PHP skript skriveni-podaci.php moze da izvadi taj podatak i da ga prikaze.
