Insert data from multiple array form inputs using php and mysql

Question

i have three fields

<textarea rows="2" name="answer[]" ></textarea>
<select name="fraction[]">...
<textarea rows="2" name="feedback[]"></textarea>

the user should fill this fields more than one time at least four times then i use php to loop through this fields to insert it in database

$answer = isset($_POST['answer']) ? $_POST['answer'] : "" ;
$fraction = isset($_POST['fraction']) ? $_POST['fraction'] : "" ;
$feedback = isset($_POST['feedback']) ? $_POST['feedback'] : "" ;

foreach($answer as $key=>$value){
    $answer = $value;
    $fraction = $fraction[$key];
    $feedback = $feedback[$key];
    $query = "insert into `question_answer` ( answer, fraction, feedback) values ('$answer', '$fraction','$feedback')";
    $questions->insertData($query,$con);
}

this insert number of records , the first record contain all values as i want but the other records only contain the value of the field related to the array i loop through and the other fields are empty..any help ??

You overwrite your variables in the first loop... Take this:

$answer = isset($_POST['answer']) ? $_POST['answer'] : "" ;
$fraction = isset($_POST['fraction']) ? $_POST['fraction'] : "" ;
$feedback = isset($_POST['feedback']) ? $_POST['feedback'] : "" ;

foreach($answer as $key=>$value){
    $query = "insert into `question_answer` ( answer, fraction, feedback) values ('$value', '$fraction[$key]','$feedback[$key]')";
    $questions->insertData($query,$con);
}

Of course the OP should prevnet SQL Injections too and make sure the user entered all data so that there is no answer without feedback or so.
