Math question by a form don't work

[KlappenVanJePa]

Hello, 
 
I have set up a form but when I fill it in it says the captcha math question is wrong. 
I have checked everthing but I can't find my problem.

 

The strange thing that I get the error but It still sends a email. 

http://klappenvanjepa.co.nf/

<?php 
	
					$num_one = rand() % 10;
					$num_two = rand() & 10;
					$final_num = $num_one + $num_two;
					$_SESSION['answer'] = $final_num;
					echo $num_one . ' + ' . $num_two . ' = ';
					    ?>
    
    				
    				
   					<input type="text" name="answer" /> <br />
				
                        <input type="submit" name="send_message" value="Send!">		 

 

 

 

 

$user_answer = $_POST['answer'];
$real_answer = $_SESSION['answer'];



if(empty($naam) OR empty($email) OR empty($email)) {
	echo "Your forget somthing.";

} elseif($user_answer != $real_answer) {
	echo "Can't send because the question is wrong.";

 

Can someone please help me with this problem. 

 

Thanks

Do a var_dump on both answers. What are they?

Are you using session_start() on both pages?

 

 

EDIT:

You don't show enough code to see that problem. All you have is this

 

elseif($user_answer != $real_answer) {
    echo "Can't send because the question is wrong.";

 

If you close out that execution block and have code later on in the page to send the email, then that error handling would do nothing to prevent that. You need to ensure the email logic is only run if there are no errors.

I am fairly new to php and I do not know what a var_dump is.

I've looked on google but I can not clearly find it there. And also I looked in your "debbugging  url but I still do not understand it". 

 

Can you please explain it otherwise. 

Thanks

var_dump.

 

And yes, you need session_start() as the first line on each page.

Thanks very much, that was the problem.  I'd did not expected the problem was so simple. 

[KlappenVanJePa]

Oke I thought the problem was finaly over because it says that it was sent, but now I don't get a email anymore. 

[Jessica]

You didn't post any code that sends an email.

As I stated previously, you don't provide enough code to see where that problem may be.

<?php

session_start();

$email = $_POST['email'];
$naam = $_POST['naam'];
$onderwerp = $_POST['onderwerp'];
$vragen = $_POST['vragen'];
$user_answer = $_POST['answer'];
$real_answer = $_SESSION['answer'];

if(empty($naam) OR empty($email) OR empty($email)) {
	echo "Uw bent iets vergeten in te vullen.";

} elseif($user_answer != $real_answer) {
	echo "can't send because the question is wrong.";
}

else {
	mail($to, $subject, $message, "From: $email");
	echo "Message sent";
}
$to = '[email protected]';
$subject = 'contact';

$body = <<<EMAIL

Naam: $naam
Email: $email
Onderwerp: $onderwerp
vragen: $vragen

EMAIL;

$header = ('Location: index.html');

if($_POST){
if($naam == ''|| $email == ''|| $vragen == '' ){
$feedback = 'U forget something';
}else{
mail($to, $subject,  $body, $header);
$feedback = 'Thanks The message has been sended';
}
} 
?>

So... you send the email before you define the variables that you use to send the email.

[KlappenVanJePa]

Yes, I guess so. 

That was pretty stupid of me

I've now done and put it on the end of the page,  but nothing changes it still don't works.

Do you see a theme yet with your posts and ours?

[Jessica]

1. $header = ('Location: index.html'); This is just way wrong. header() is a function. I doubt you want to create a string with "Location: index.html' stored in it.

2. you use $body and $message. Pick one.
