[PHP] pobierz, plaintext


próbuje dodać kod CAPTCHA, wszystko działa ok, kod się wyświetla prawidłowo. lecz nie wiem
jak zrobić żeby kod był sprawdzany, bo teraz w pole pod obrazkiem można wpisać byle co i można wysłać wiadomość,
za sprawdzenie odpowiada poniższy plik: "sprawdz.php"

[PHP] pobierz, plaintext 
  1.  
  2. <?
  3. session_start();
  4.  
  5. if($_POST['captcha'] != $_SESSION['captcha']){
  6.  
  7.         echo '<span style="color: #ff0000;">Błędny kod. Spróbuj jeszcze raz.</span> <a href="index.php" title="Powrót">Powrót</a>';
  8.  
  9. }else{
  10.  
  11.         echo '<span style="color: #008000;">Kod poprawny.</span>';
  12.  
  13. }
  14. ?>
[PHP] pobierz, plaintext

A ten sprawdz.php includujesz jakoś w powyższym fragmencie kodu?

Wystarczy coś takiego:
[PHP] pobierz, plaintext 
  1. session_start();
  2. if($_POST['captcha'] != $_SESSION['captcha']){
  3.   $send = "no";
  4.   echo '<span style="color: #ff0000;">Błędny kod. Spróbuj jeszcze raz.</span> <a href="index.php" title="Powrót">Powrót</a>';
  5. }
