Undefined offset

Posted on 16th Feb 2014 07:03 pm by admin

The following script checks to see if the user answer matches the correct answer.

Form Fields are set up the following way...

user_answer[$i] | value = a
user_answer[$i] | value = b
user_answer[$i] | value = c

all radio fields (above)

orgid[$i] | value = $i
answer[$i] | value = (a or b, c)

all hidden fields (above)

$i = question id/number

Basically when question answer isn't selected an undefined offset error message is generated. Adding if empty or isset messes up the order.


Code: foreach ($_POST['orgid'] as $k =>$v) {
$orgid[$k] = $v;
}

$k = 0;
$m = 0;
while ($k <= 19) {
if ($_POST['user_answer'][$k] == $_POST['answer'][$k]) {
$correct++;

unset ($_POST['user_answer'][$k]);
unset ($orgid[$k]);
} else {
$incorrect++;
}
$k++;
}
Any ideas/suggestions?
