    Im using this code to bring back records from my shoutbox, what i would like to do...when the user posts a message for it to be displayed to them straight away, and then bring it back from the database.

     

    So what I am trying to do is write an SQL statement that brings back all the other messages apart from the ones that are submitted by the user user that is logged in.

     

    Can anyone help me. thanks

    Need help with shoutbox....

    Hi all,

     

    I have been working on a shoutbox for ages, from the feedback i have been getting is that the problem with it is that messages take to long to be displayed.

     

    Currently

     

    1.) Users write a message and send it.

    2.) It then is added to the database.

    3.) Every 3 seconds a call to a php file called ajaxgetshoutbox.php is called to get the last message posted.

    4.) This data is then put into JSON format.

    4.) This is then outputted to the screen.

     

    Obviously i cant put to much pressure on the server by posting a request to the database every second.

     

    Have i gone about this all the wrong way?

     

    Is there a way to improve responsivness of message sending??

     

    If anyone would like to look at the code, please ask. Or you can view it live at http://shoutbox.thedesignmonkeys.co.uk

     

    thanks

    Timestamp Always Starts at 3600

    in PHP Coding Help

    Posted

    Hi all,

     

    can someone tell me whenever i update my users timestamp on the server it always starts at 3600 but locally it always starts at 0. this is the code im running...

     

    user_online.php

     

    <?php
session_start();
include("dbconnect.php");

$sql = mysql_query("SELECT last_activity,username FROM users");

echo "<ul class='online'>";
while($row = mysql_fetch_assoc($sql)) {

$usertime = strtotime($row['last_activity']);

$difference = time() - $usertime;
$idletime = 300; //3 Minutes

echo $difference." is the difference<br/>";
echo $idletime." is the idletime<br/><br/>";

if($difference > 600)
{
echo $row['username']." is offline<br/>";
} else

if($difference > 150)
{
$idletime++;
echo $row['username']." is idle<br/>";
} else {

echo $row['username']." is online<br/>";
}

}


?>

     

    update.php

     

    <?php
session_start();

include('dbconnect.php');
$username = $_SESSION['login']['username'];
$sql = mysql_query("UPDATE users set last_activity = CURRENT_TIMESTAMP  WHERE username = '$username'");

?>

    Need Help With Time Script

    in PHP Coding Help

    Posted

    Ok....

     

    The reason for the ONLINE/IDLE/OFFLINE thing is that it is a Chat Application written in JQuery/PHP. Much like the popular facebook, when a user has been inactive for a certain amount of time, it shows that user to be idle.

     

    Then after a longer amount of time, it times the user out and they need to log in again. This is what I am trying to achieve here.

     

    I have updated the code to this..

     

     

    userstatus.php

     

    <?php
session_start();
include("dbconnect.php");

$sql = mysql_query("SELECT last_activity,username FROM users");

echo "<ul class='online'>";
while($row = mysql_fetch_assoc($sql)) {

$usertime = strtotime($row['last_activity']);

$difference =time() - $usertime 
$idletime = $difference - 150;

echo $difference." is the difference";

if($difference < -500)
{
echo $row['username']." is offline<br/>";
} else

if($idletime <= 0)
{
$idletime++;
echo $row['username']." is idle<br/>";
} else {

echo $row['username']." is online<br/>";
}

echo "--------------------------------<br/>";

}


?>

     

     

    then the

     

    update.php

     

    <?php
session_start();

include('dbconnect.php');
$username = $_SESSION['login']['username'];
$sql = mysql_query("UPDATE users set last_activity = CURRENT_TIMESTAMP  WHERE username = '$username'");

?>

    I am trying to write a script to let me see who is online, who is idle and who is offline. This is the script I have so far.

     

    <?php
session_start();
include("dbconnect.php");

$sql = mysql_query("SELECT last_activity,username FROM users");

echo "<ul class='online'>";
while($row = mysql_fetch_assoc($sql)) {

$usertime = strtotime($row['last_activity']);

$difference = $usertime - time();
$idletime = $difference - 150;

if($difference < -500)
{
echo $row['username']." is offline<br/>";
} else

if($idletime <= 0)
{
$idletime++;
echo $row['username']." is idle<br/>";
} else {

echo $row['username']." is online<br/>";
}

echo "--------------------------------<br/>";


}


?>

     

    Everytime a message is sent, i run the script below to update the users last activity timestamp ahead so it knows there has been activity from the user so get it to say they are online.

     

    After an amount of inactivity i want it to say they are idle.

     

    <?php
session_start();

include('dbconnect.php');
$username = $_SESSION['login']['username'];
$sql = mysql_query("UPDATE users set last_activity = CURRENT_TIMESTAMP + 100  WHERE username = '$username'");

?>

     

    The problem I am having is when the user sends the message, im not sure how much i have to update the time by for the countdown to start again.

     

    Thanks

    Using time to work out Online Status

    I really cannot guage anything from this as it is ASP....

     

    What do you think is the best thing to update the time with everytime a message is sent.

     

    update.php

    <?php
session_start();

include('dbconnect.php');
$username = $_SESSION['login']['username'];
$sql = mysql_query("UPDATE users set last_activity = CURRENT_TIMESTAMP WHERE username = '$username'");

?>

     

    guestsonline.php

     

    <?php

include("dbconnect.php");


$sql = mysql_query("SELECT last_activity,username FROM users");

echo "<ul class='online'>";
while($row = mysql_fetch_assoc($sql)) {

$usertime = strtotime($row['last_activity']);
$currenttime = time();


if($usertime < $currenttime)
{
echo "online";
}

}


?>

    nope this is what ive got

     

    <?php

include("dbconnect.php");


$sql = mysql_query("SELECT last_activity,username FROM users");

echo "<ul class='online'>";
while($row = mysql_fetch_assoc($sql)) {

$usertime = strtotime($row['last_activity']);
$currenttime = time();

$offlinetime = $usertime - time() * 60 * 1;

if($usertime < $currenttime)
{
echo $row['username']."IDLE<br/>";

}elseif($usertime < $offlinetime) {

echo $row['username']."OFFLINE";

} else {

  echo $row['username']."ONLINE<br/>";
}

}
echo "</ul>";


?>

     

    it works between ONLINE and IDLE just not offline!!
