I am trying to update the amount of postings remaining down everytime a user posts so if the user had a limit of 200 posts then when the user posts it counts down by 1 and updates the table field for that user to 199.
Now the error that I am getting is that it does not count down correctly and puts 20 instead and then the next time the user posts after that it will put 0.
$remain = mysql_query("SELECT postings_remaining FROM ".TBL_USERS." WHERE username = '$session->username' limit 1");
$postings = $remain; //Count the number of postings remaining the user has
$postingsremain = $postings - 1; //Remove 1 to the users posting remainings
$sqlcountdown = mysql_query("UPDATE ".TBL_USERS." SET postings_remaining = '$postingsremain' WHERE username = '$session->username'");
If someone can help me with this function I would very much appreciate it.
