In this file answer is stored using GET method, but unable to get inserted into the database:
insert.php
<?php
require 'searched.php';
$conn=new mysqli("localhost","khushank","sethi","q&a");
if($conn->connect_error){
echo "unable to connect";
}
echo"connected";
if($_SERVER['REQUEST_METHOD']=='GET'){
if(isset($_GET['comment'])){
$ans=mysql_real_escape_string($_GET['ans']);
$username=$_SESSION['user'];
//$ques=$_GET['$ques'];
$insa=" INSERT INTO answer(aemail,ans) VALUES('$username','$ans') " ;
if($conn->query($insa)){
echo"inserted";
echo"<script type='text/javascript'>".'alert("your answer is posted successfully");
</script>';
}
else{
echo"not inserted";
}
}
}
else{
echo"1";
}
$conn->close();
?>
I'm unable to insert the values stored in $ans.
