if isset PHP не работает?

Question

Хорошо, я пытаюсь установить captcha вверх, но с этим кодом в, он ломается.

if(isset($_POST["captcha"])) 
    if($_SESSION["captcha"]==$_POST["captcha"]) 

Когда я это делаю, страница работает, но captcha позволяет вводить неверные сообщения.

Parse error: syntax error, unexpected '"', expecting T_STRING or T_VARIABLE or T_NUM_STRING in /hermes/waloraweb085/b2027/moo.lutarinet/jointest.php on line 71

$pagetitle = "Home";

Помогите пожалуйста кто-нибудь?

Строка 71: если (Исеть ($ _ POST [ "CAPTCHA на"]))

Line 72: если ($ _ SESSION [ "CAPTCHA на"] == $ _ POST [ "CAPTCHA на"])

Answer 1

EDIT:

Вы упускаете END;:

ECHO <<<END 

<br><br> 

<b><center><i><u>DO NOT</u> USE YOUR NEOPETS PASSWORD OR PIN NUMBER!!!</b></i></center><p> 

END; // You forgot to include this 

Кстати, session_start() должно быть первым, что называется в сценарии, как это необходимо сделать до начала любого другого выхода.

Кроме того, попытайтесь получить ваши брекеты, чтобы с ветвями многострочных (облегчает сканирование):

if (isset($_POST["captcha"])) 
{ 
    if ($_SESSION["captcha"] == $_POST["captcha"]) 
    { 
     //CAPTHCA is valid; proceed the message: save to database, send by e-mail ... 
     echo 'CAPTHCA is valid; proceed the message'; 
    } 
    else 
    { 
     echo 'CAPTHCA is not valid; ignore submission'; 
    } 
} 

Answer 2

if(isset($_POST["captcha"])) 
if($_SESSION["captcha"]==$_POST["captcha"]) 
{ 
    //CAPTHCA is valid; proceed the message: save to database, send by e-mail ... 
echo 'CAPTHCA is valid; proceed the message'; 
} 
else 
{ 
    echo 'CAPTHCA is not valid; ignore submission'; 
} 

Вы упускаете фигурную скобку на первом, если ...

if(isset($_POST['captcha'])) 
{ 
    if($_SESSION['captcha'] == $_POST['captcha']) 
    { 
     //CAPTHCA is valid; proceed the message: save to database, send by e-mail ... 
     echo 'CAPTHCA is valid; proceed the message'; 
    } 
    else 
    { 
     echo 'CAPTHCA is not valid; ignore submission'; 
    } 
} 
// Need another else for first if here or keep it closed if you don't have an else
