disallow users from visiting site twice in 15 minutes
to keep it short, all you need to do is save the timestamp whenever the user enters the page in a MySQL database. Let's say the coloumn in which it is saved is called 'last_time' and the coloumn in which the username is saved is 'username'. Then whenever the page is loaded, get the variable for the current user. Let's say the variable is $user. Get the corresponding value for last_time from the database:
SELECT last_time FROM mytable WHERE username = $user
You must be knowing the rest with mysql_fetch_array and all that, so won't go much into it. Let's suppose you get the last time in the variable as $last_time. All you need to check is whether the current timestamp is more than 15 minutes or not:
also remember that whenever you show the page, fill the data in the last_time entry with the corresponding username with the current time stamp.
hope it helps

| Code: |

if(!((time() - $last_time) > 15*60)) { die("You cannot view the page twice in 15 minutes"); } else { //Show the page here } |
also remember that whenever you show the page, fill the data in the last_time entry with the corresponding username with the current time stamp.
