Cannot call Session Variable to regular variable for SQL lookup

bakertaylor28 posted a topic in PHP Coding Help

My login script stores the user's login name as $_SESSION[ 'name'] on login. For some unapparent reason, i'm getting errors stating that $user and $priv are undefined variables, though I've attempted to define $user as being equal to $_SESSION['name'], using $user to look up the the user's privilege level (stored as the su column ) in the SQL table, and then where the result of the sql query is $priv which is then evaluated in an if statement. I can't seem to figure out why this might not be working. The code I'm using: <?php session_start(); function verify() { //verify that the user is logged in via the login page. Session_start has already been called. if (!isset($_SESSION['loggedin'])) { header('Location: /index.html'); exit; } //if user is logged in, we then lookup necessary privleges. $_SESSION['name'] was written with the login name upon login. Privleges // are written in db as a single-digit integer of of 0 for users, 1 for administrators, and 2 for special users. $user === $_SESSION['name']; //Connect to Databse $link = mysqli_connect("127.0.0.1", "database user", "password", "database"); if (!$link) { echo "Error: Unable to connect to MySQL." . PHP_EOL; echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL; echo "Debugging error: " . mysqli_connect_error() . PHP_EOL; exit; } //SQL Statement to lookup privlege information. if ($result = mysqli_query($link, "SELECT su FROM accounts WHERE username = $user", MYSQLI_STORE_RESULT)) { //LOOP TO CYCLE THROUGH SQL RESULTS AND STORE Privlege information as vairable $priv. while ($row = $result->fetch_assoc()) { $priv === $row["su"]; } } // close SQL connection. mysqli_close($link); // Verify privleges and take action. Only a privlege of "1" is allowed to view this page. A privlege of "2" indicates special //accounts used in other scripts that have certain indermediate additional functions, but are not trusted administrators. if ($priv !== 1) { echo $_SESSION['name']; echo "you have privlege level of $priv"; echo " "; echo 'Your account does not have the privleges necessary to view this page'; exit; } } verify(); ?>

How to access a PHP variable in both CSS and HTML?

MythicalTomatoSoup posted a topic in PHP Coding Help

Hey! I want to create a website that can test your counting pace. I’ll make colored, square div that change color after 10 to 30 seconds when you hover over it, and then you’ll type down how long you think it took in a form to check if you’re right. My solution to do this is to create the PHP variable $time = rand(10,30), and in CSS get the div:hover transition-delay to be $time. Then, after the form, I need the same variable for if($_POST[timeguess] = $time) {echo “Correct!”}. I have no idea how to access the same variable in both the CSS and HTML, so I hope some of you can help me out! Thanks
