Why it doesn't display POST value?

Error: Notice: Undefined index: q[abc] in line: echo $_POST['q[abc]'];


<form method="POST" action="post.php" name="tq">

    <input type="hidden" name="q[id]" value="1035">

    <input type="radio" name="q[abc]" value="3001"></div>


    <input type="radio" name="q[abc]" value="3002"></div>


    <input type="radio" name="q[abc]" value="3003"></div>


    <input type="submit" name="add" value="Next">



if (isset($_POST['add'])) {

    echo $_POST['q[abc]']; //error line

Instead of echo $_POST['q[abc]']; you should try echo $_POST['q']['abc'];
