something i cant under stand

03 July 2013 - 07:34 PM

hey there,
lately im was working on a new application that required alot of ajax requests...
i was wondering, many websites return fom the server a json object and then creates the html elements with javasript and then appending it to the document. why not return the html from the server and then just append it to a div, which is more easier!

for example, lets say i want to print a table with shop items and their prices, why should i return a json object and then print a table with javascript with the data insted of return the whole html table from the server? am i missing something?

thanks in advance.

update user in DB every hour

14 March 2013 - 07:10 AM

hey, im building a web based browser game.

what im trying to do is to give the user 15 tickets every hour.

what i did is to store the time the user got the tickets last time, and when the user loging in again, or refresh the page,

i check how many hours passed from the last time he got tickets, then i update his tickets to 15*$hours.

the problem is that it updates the tickets all the time :|

 

here is my code so far:

$member_id = intval($this->member['id']);

if ($member_id != 0) {
    $ticketsToAdd    = 0;
    $lastTicket      = $this->member['last_tickets']; // last time the user got tickets
    $ticketsJump     = $INFO['tickets_jump'];         // how many tickets to add the user, set to 15
    $ticketsJumpTime = $INFO['tickets_jump_time'];    // after how many hours update the user tickets, set to 1
    $timeDiff        = $std->timePassed($lastTicket); // calculate the time diffrence between now and the last time the user got tikets
    
    if ($timeDiff['hours'] >= $ticketsJumpTime) {
        $ticketsToAdd = $ticketsJump * $timeDiff['hours'];
        
        if ($timeDiff['minutes'] != 0) {
            $lastTicketWorkAround = time() - ($timeDiff['minutes']*60);
        } else {
            $lastTicketWorkAround = time();
        }

        $DB->query("UPDATE users SET tickets = tickets+".$ticketsToAdd.", last_tickets='".$lastTicketWorkAround."' WHERE id='".$this->member['id']."'");
    }
}

public function timePassed($str) {
        $sec = time() - $str;
        return array(   "hours"     =>  intval($sec / 60 / 60),
                        "minutes"   =>  intval($sec / 60));
       # if($sec < 60) {
            /* if less than a minute, return seconds */
       #     return $sec . " seconds ago";
       # }
       # else if($sec < 60*60) {
            /* if less than an hour, return minutes */
       #     return intval($sec / 60) . " minutes ago";
       # }
       # else if($sec < 24*60*60) {
            /* if less than a day, return hours */
       #     return intval($sec / 60 / 60) . " hours ago";
       # }
       # else {
            /* else returns days */
       #     return intval($sec / 60 / 60 / 24) . " days ago";
       # }
    }

i add some comments to the code so you can understend better.

the whole code is a part from a class...

 

Thanks in advance!
