    check if times overlap

    in Javascript Help

    Posted

    hello,

    i have an event reservation system. i need to make sure that every time someone is booking a new time, it's not overlap another reservation.

     

    for example lets say i have an event reserved starting at X and ending at Y

    X = Wed Sep 10 2014 07:30:00 GMT+0000
Y = Wed Sep 10 2014 08:00:00 GMT+0000

    and now im reserving a new event

    start = Wed Sep 10 2014 09:30:00 GMT+0000
end = Wed Sep 10 2014 09:30:00 GMT+0000

    how can i check if they are not crushing?

    lets say the first event starts at 12:00 and end 14:00,

    i need to make sure that the new event is not held between these hours.

    it need to be started and end before 12:00 or after 14:00.

     

    thanks in advance!

    something i cant under stand

    in Javascript Help

    Posted

    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

    in PHP Coding Help

    Posted

     

    What about this? I'm about 90% clear on what you require, so I'm using my judgement.

     

     

    $member_id = intval($this->member['id']);
 
 if($member_id >= 1) {
   $lastTickets    = $this->member['last_tickets'];
   $ticketsPerHour = $INFO['tickets_jump'];
   
   $timeDifference = $_SERVER['REQUEST_TIME'] - $lastTickets;
   $timeHours      = floor($timeDifference/60/60);
   $lastHour       = $lastTickets+($timeHours*60*60);
   
   if($timeHours >= 1) {
     $ticketsToAdd = ($ticketsPerHour*$timeHours);
     
     $query = "UPDATE `users` SET `tickets` = `tickets`+{$ticketsToAdd}, `last_tickets` = {$lastHour} WHERE `id` = {$member_id}";
 
     echo $ticketsToAdd .' - '. $lastHour .'<br>';
     echo $query;
   }     
 }

     

    as i see it now, it works perfectly!

    Thank you!

     

    No one benefits from sarcastic posts, get over it.

     

    The way I look at it, relating it to games:

     

    - One uses a cron job to calculate something that is publicly available. For instance, a score in a leaderboard in a game. Its imporatnt that this is always up to date even if the user itself is no longer online

    - One uses a regular page load /script to calculate stuff that only the user itself sees. For instance, the "resources" I have for a game. I dont care if I have a lot of them, or even a little. As long as the number is correct the moment I log in, I will not see any difference.

     

    In this case, I dont see how a cron job would improve the script.

     

    Thanks for clearing this up to everyone ^^

    update user in DB every hour

    in PHP Coding Help

    Posted · Edited by aviavi

    first of all Thanks!

    second, it almost work...

    i set the time i have to get tickets to 14:19, and i did get this tickets, so the next time should be 15:19...

    insted it tells the next time is 15:00...

     

    another thing is that i have to handle minutes too...

    for example, lets say the last time i got tickets wast 12:20, then the next time i logged in is 14:10

    so i have to get 30 tickets for 2 hours, and take in account that i have to get tickets again in the next 10 minutes!

     

    and yea, for the purpose im doing this tickets it is make a diffrence if a user will get tickets a few minutes after he registered :|

     

    Thanks again!

    update user in DB every hour

    in PHP Coding Help

    Posted · Edited by aviavi

    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!

   }
   for (var i = 0, L = D.length; i < L; i++) {
 D[i] = parseInt(D[i], 10);
   }
   D[1] -= 1;
   while (D.length < 6) D.push(0);
   if (M[4]) {
 min = parseInt(M[6]) * 60 + parseInt(M[7], 10); // timezone not UTC
 if (M[5] == '+') min *= -1;
   }
   try {
 d2 = fromUTCArray(D);
 if (min) d2.setUTCMinutes(d2.getUTCMinutes() + min);
   } catch (er) {
 // bad input
   }
   return d2;
  }

    finding an email in a text

    in Regex Help

    Posted

    hey,

    im trying to recognize an email address in a text paragraph, for example:

     

    1111111 <br/> 123emailaddress123@gmail.com <br/> 22222

     

    and replace it to:

     

    1111111 <br/> <a href="mailto:123emailaddress123@gmail.com">123emailaddress123@gmail.com</a> <br/> 22222

     

    it's my first time dealing with regex and so far i reached this:

     

    $text = "1111111 <br/> 123emailaddress123@gmail.com <br/> 22222";
$post_eregi = '/(.)([^0-9][a-zA-Z0-9_]+([.][a-zA-Z0-9_]+)*[@][a-zA-Z0-9_]+([.][a-zA-Z0-9_]+)*[.][a-zA-Z]{2,4})(.)/';

echo preg_replace($post_eregi, "<a href='mailto:$2'>$2</a>", $text);

     

    unfortunately it doesnt work :(

     

    but if i remove the breakline  tag before the email address it's works grate! any suggestions or ideas what wrong?

     

    thanks in advance!
