I, know its a bit messy but lets me see it and design it in Dreamweaver

Any way, for the comment system for users, I want it to show their avatar as well, which is stored in the users table. How would one do this.

I did think of it submitting the avatar along with the post but then it wouldnt update if the user would to change their avatars :\

Any helps???

Hello PHP mates!

I am having some doubts and I am going to share them with you so maybe someone can help. Okay, I know how to make signup and login page. And here is the problem. How to make signup page for multiple types of users? For example, type A user has its own signup form, user type B also has its own and same goes for C type of user. How can I make that?

Thanks in advance PHP freaks!

Hello Guys, I would really appreciate some feedback on this one.
Here's the basic simplified code for my bidding system site (querys for when a user sends a new valid bid):
Its working fine but if 2 users send a bid at exactly the same precise moment (even same milliseconds), I have 2 problems (described below code, for better understanding)

Please picture this code as if its happening 2 times at the same time (from 2 different users)

Code: [Select]

$time = microtime(true) * 10000;

$result = mysql_query("UPDATE `AUCTIONS` SET Current_Price = Current_Price + '$increase_price', Bids = Bids + 1, Bidder = '$bidder', Bidder_Time = '$bidder_time' WHERE PId = '$id'");
//grab the current price to save on bidding history DB


if($result)
{
$resultPrice = mysql_query("SELECT Current_Price FROM AUCTIONS WHERE PId = '$id'");
while($row=mysql_fetch_array($resultPrice))
{
$current_price = $row['Current_Price'];
    }

if($resultPrice)
{
$result = mysql_query("INSERT INTO `BIDDING_HISTORY_DB` (Id, Bidder, Bidder_Time, Raw_Time, Ip, Type, Bid_Amount) VALUES ('$id', '$last_bidder', '$last_bidder_time', '$time', '$client_ip', '$credit_type', '$current_price')");
        }
}

If 2 users bid at exactly the same SAME moment, its possible that on BIDDING_HISTORY_DB... I get the Bid_Amount field with the same value (when it should be always 1 number higher than the previous) ( Bid_Amount is coming from $current_price) $current_price grabs the new updated value from the AUCTIONS DB on the first query (Current_Price = Current_Price + '$increase_price').
So its impossible to have 2 values that are the same (at least I am not expecting that), but I realized that if the query from 2 users are being processed at the same time and the UPDATE AUCTIONS query is processed 2 times and AFTER THAT then the SELECT Current_Price FROM AUCTIONS WHERE PId = '$id' is processed on both bids...that is when the Current_Price is grabbed with the same value for both USERS!! Any ideas on how I can find a solution to this ???

The other problem is that I am knowing which bid was made (by which user) before/after because of the $time variable. But sometimes when 2 bids are made at the SAME precise time with the same milliseconds (yes it happens) ... this is when problems arise (because 1 user could have as Current_Price 10.11 and the other one 10.12 and then on DB the user with 10.12 could be shown as if he made the bid first, any ideas/suggestions on how I can find a solution to this?

Hiya! ,

I'm currently working on a script that will allow me to track the total users on my website, and how many of these user are logged in members, or guests.

I need to be able to find out the total users, total logged in, and total guests within the last 15 minutes, and the total users, total logged in, and total guests for today.

Ideally, I would like to user only one table for this, and would also like to group together records in the database that have the same users_id and ip_address, as there's not much point in storing this more than once.

I currently have a table that contains the following fields.

sid - Stores the users session ID.
user_id - Stores the user id of a logged in user. 0 is stored if the user is a guest.
ip_address - Stores the IP address of the user.
last_updated - Stores a timestamp of when the user was last active.

I look forward to reading your responses

Cheers!
