It seems as if you are extremely new to coding so I'll try to help you out.
Here is the code you can use and I'll explain below.
<?php
session_start();
$host = 'localhost'; $db = 'db-name'; $user = 'db-user'; $pw = 'db-pwd';
$conn = new PDO('mysql:host='.$host.';dbname='.$db.';charset=utf8', $user, $pw);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
try {
$tbl_name = 'table-name-here';
$un = $username;
$sql = "SELECT * FROM $tbl_name WHERE username=:un";
$query = $conn->prepare($sql);
$query->bindValue(':un', $un, PDO::PARAM_STR);
$query->execute();
$row = $query->fetch(PDO::FETCH_ASSOC);
$totalRows = $query->rowCount();
} catch (PDOException $e) {
die("Could not get the data: " . $e->getMessage());
}
$_SESSION['spinNum'] = $row['name-of-your-field-with-spin-numbers'];
?>
Then...
if($_SESSION['spinNum'] >= 1) {
// allow them to do something
} else {
echo "I'm sorry. It looks like you don't have any spins left. Please try again later.";
}
This code is written using pdo_mysql. You might want to read up on it here.
Line 2 starts your session
Lines 3-5 creates a connection to your database. Make sure to replace "db-name", "db-user" & "db-pwd" with your information.
On line 8 replace "table-name-here" with your database table name
On line 9 you can set "10" to whatever minimum number you want to make sure the account holder has.
On line 19 change "name-of-your-field-with-spin-numbers" to the actual name of the field in your database table that stores the account users available spins.
Now you can use $_SESSION['spinNum'] on your other pages.
Don't forget to use session_start(); at the top of any page where you want to use session variables.
