my other if else statement is executing php
Question
I have 3 forms with 3 radios each but executed one at a time because of random generator. If I click a radio, it will go to next page and will be checked by the if else statement. Now my problem is, when it gets answered and it's correct, it will output yes. However, my other if else statement of my other radio executes. Since it's not answered, it assumed that it was wrong, so it outputted no.
here's my code:
<!doctype html>
<html>
<head>
<title>Question and Answer</title>
</head>
<body>
<?php
//Creating random numbers
$rid = rand(1,3);
?>
<?php
if ($rid == 1){
echo "
<form action='answer.php?id=1' method='post' id='quizForm' id='1'>

}

Here is a cleaner way to do it. Inside is_correct function, it check if particular answer exist in $_POST , if so it returns if the answer is correct:
function is_correct()
{
$answer = array(
'answerOne' => 'A',
'answer2' => 'B',
'answer3' => 'C',
);
foreach ($answer as $k => $v) {
if (array_key_exists($k, $_POST)) {
return $v == $_POST[$k];
}
}
return false;
}
if (is_correct()) {
echo "yes";
} else {
echo "no";
}
