I'm creating a quiz-like structure. For that i'm trying to get the answer of each question and insert it into my database with the type of question that was answered. However i'm having trouble putting these data in variables and i'm getting:
Notice: Undefined index: question-0-answer
in the commented part of the code. Any help..
$options = '';
$filter=mysql_query("select afnumber from employees WHERE Status='Employed '");
while($row = mysql_fetch_array($filter)) {
$options .="<option >" . $row['afnumber'] . "</option>";
}
$menu="<form id='filter' name='filter' method='post' action=''>
AFNumber : <select name='SelectAF' id='filter' style='color:grey;'>" . $options . "</select>
Evaluation Test Type : <select name='Type' id='type' style='color:grey;'><option selected='selected'></option><option value='loyalty'>Loyalty</option><option value='performance'>Performance</option></select>

Answer 1

The $counter for outputting the radiobuttons is initialized with the value 1 but when reading the values of radiobuttons at the end of your script, you are starting with $counter = 0;.
Please change
for( $counter=0; $counter < $numQuestions; $counter++ ){
to
for( $counter=1; $counter <= $numQuestions; $counter++ ){

Answer 2

You are running loop statically 10 times in comment and what if database have less than 10 records? You need to run loop a many times as db having records or you can put condition before insert by isset($_POST['question-'.$counter.'-answers'])
