Question 1

I’ve tried numerous things to make this functionality work. I’ve searched all over stackoverflow to see if there was a solution for the particular issue that I’m having and I’m getting no where. I was wanting to reset the session variable to have the value of 0 when the user hit’s the reset button, which is simply just a submit button. I’ve tried changing it to a get and then setting the if statement to pull from the server to see if the request is GET. I did the same with POST and had no luck. The session just remains and won’t destroy at all. It’s like it’s just neglecting the if statement because I’ve tried doing a test with an echo statement and get nothing in response. Any ideas of what might be causing the issue? I am populating the session variable then setting it to a variable called $db_value. The reason I did that is so that I can write the result to the database and then pull again from the database when the user continues playing.

<?php session_start();
    $host = "localhost";
    $user = "username here";
    $pass = "";
    mysql_connect($host, $user, $pass) or die(mysql_error());
    mysql_select_db("RPS") or die(mysql_error());
    mysql_query("SET SQL_SAFE_UPDATES=0;"); // allows updating of table
    mysql_query("Create table if not exists RPS (score int);");
?>

Question 2

You might try $_REQUEST[‘Reset’] instead of get or post to cover your bases. Use the following sequence at the very top of your code only to destroy a session…

$session_id = session_id();

if(empty($session_id)){
 session_start();
}

if(isset($_REQUEST['Reset'])){
 session_unset();
 session_destroy();
 $_SESSION = array();
 session_start();
 session_regenerate_id();
}

by and by, your form is way wrong. I doubt you’re even getting data from the values here. change it to this:

echo ' You\'re score is currently: ' . $_SESSION['Score'];
echo '<form method="POST" action="rps.php"><input type="hidden" name="hidden" /><input type="submit" value ="Play Again" name="Reset" /></form>';

…

then on the top of the page do what i put plus a little of yours…

$session_id = session_id();

if(empty($session_id)){
 session_start();
}

if(isset($_REQUEST['Reset'])){
 $_SESSION['Score'] = 0;
 $db_value = $_SESSION['Score'];
 session_unset();
 session_destroy();
 $_SESSION = array();
 session_start();
 session_regenerate_id();

 mysql_query("UPDATE RPS SET score = $db_value WHERE unique_field = $unique_field");
 header('Location:rps.php');
 exit;
}

where you use this:

if ($_POST['reset']) {

that will always return true if you write it without a condition. for the value. Plus PHP is case sensitive, so use Reset if you do it how I wrote it.

You’re not using XHTML validation, you’re using HTML 4.01 Transitional so don’t do this:

<br />

do this:

<br>

also that goes for the / on your images as well.

Final thought, use a unique value when doing your update, because your statement will change every record in the entire table. See my example with the WHERE clause.
