php - Running an INSERT query inside an If statement -


i wondering if possible run insert query if answer correct, have tried multiple types of queries creating new stmt , array , inserting them database if answer if correct, basic understanding of how works, may missing something? not getting errors returned, getting echo statement returned.

note : know trying insert questionid multiple times put data database. updated correct fields.

can enlighten me on whats issue :

<?php  // establishing mysqli connection  require_once('connection-test.php'); $mysqli = new mysqli($host,$username,$password,$database);  if($mysqli -> connect_error)die($mysqli->connect_error);   $questionid = $_post['id']; $useranswer = $_post['answer'];  $query = "select answers answers questionid=?"; $statement = $mysqli->prepare($query); $statement ->bind_param('i', $questionid);  $statement->execute();  $statement->bind_result($answer);   while($statement->fetch()){     if($answer != $useranswer){         echo "wrong";         //return previous page       }else{        echo "correct";          mysqli_query($mysqli,"insert submissions (submissionsid,teamid,questionid,answer)  values ($questionid,$questionid,$questionid,$useranswer)");       }       }    $statement->close(); ?>

turns out had free_result()before run mysqli statement
