回应会话php的名字

Question

I'm a student and I'm making a quiz using php and mysql, my problem is I'm trying to echo a name on the results page but it doesn't work.

My first page is an index page where I create a form which gets the users name which I send to my quiz.php page.

<form method="post" action="quiz.php"> 
    <img src="pictures/indeximage.jpg" alt="horrormovies" width="1024" height="640">
    <p> 
        Please Enter Your Name
        <br>
        <input type="text" name="name"> 
    </p>
    <input type="submit" name="submit" value="Start"> 
</form> 

on my quiz.php page i put make a variable and put it in a session

<?php
    //start session
    session_start();
    $var_name=$_REQUEST['name'];
    $_SESSION['ses_name']=$var_name;
?>

On my results page I have this

<?php
    session_start();
    $var_name=$_SESSION['ses_name'];

?>
<p>
    Thank you for taking the quiz  <?php echo $var_name; ?>.
</p>

Answer 1

Use isset for assign value in session variable. for good practice.

if(isset($_POST['submit']))
{
  //start session
  session_start();
  $var_name=$_REQUEST['name'];
  $_SESSION['ses_name']=$var_name;
}
