you are not getting me guyzz... i am saying that if my website is opened in any users X browser (but not doing anything on it from several hour) and user Y want to send a PM to user X only if Y knows that X can instanty reply to it...... then how would user Y came to know that user X is online..

thanx mjdamato but what if the user is sleeping and he is online (means the website is open for an hour or two)....

dude you really suck.... is anyone here other then flappy_warbucks....

I want to know how can i check wether the user is online on my website or not....

Yeah thats true.. whenever user leaves the site the session expires.... But what if the user opened the website and leave it... then for how much time session will be valid.... And how can i change its time.... that after 5 min when user will refreshed he logged in will he will be logged out.....

If i use session in my php code then for how much time the session will be valid... And how can i change the length of the session...

I have a file upload script which is working fine but i want to change the name of the uploaded file to a session varible $_session['id']... WHat should i do... I tried to do it by writing the following the following code.... $_FILES["file"]["name"]=$_SESSION['id']; But by this i looses the file extension... File can be of nay type... (.pdf, .jpg, .gif, .png) -pranshu.a.11@gmail.com

NO errors, but instead of the image file i am getting upload.php script in my upload folder..... :confused: :confused:

Well the name on the server is in lowercase... I just writed down their inUppercase to highlight it....

I using an upload script to upload image files... but the script is not working. I have created a folder named UPLOAD at same location where the file is present. But my upload script is just creating a copy of upload.php script only but not the actual image. My code is given below : if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 20000000)) { if ($_FILES["file"]["error"] > 0) { //echo "Return Code: " . $_FILES["file"]["error"] . "<br />"; } else { /* echo "Upload: " . $_FILES["file"]["name"] . "<br />"; echo "Type: " . $_FILES["file"]["type"] . "<br />"; echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />"; echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />"; */ // $_FILES["file"]["name"]=$_SESSION['id']; if (file_exists("upload/" . $_FILES["file"]["name"])) { echo $_FILES["file"]["name"] . " already exists. "; } else { move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]); $_SESSION['result']="SUCCESSFULLY UPDATED YOUR PROFILE"; header('location:members.php'); } } } else { echo "Invalid file"; } } What should i do.... Do i need to have some folder to store temporary files.... ????

@AyKay47 : I dont want to use a session because i am destroying the session at the end of page1.php but i want to take $var much more ahead.. And i dont think that their is a way to destroy only some session... As i will apply session_destroy() all running session will destroy.....

KIRA i know these GET and POST method... But my question in little bit defferent... Suppose I have a php page page1.php with following code : <?php $var ="Hello WOrld" header('location : page2.php'); ?> ANd their is page 2 page2.php <?php echo $var; ?> This is not working and i dont want to initiate a session on page1.php .. What should i do >...

Is their any way to take a variable (declared in a page 1) to another page... I dont want to use it as a session variable... -pranshu.a.11@gmail.com

Thanx webstyles...

i Have two page login.php and verify.php In login.php user is entering Username and Password and in the action of the form i am writing verify.php. If verification is a success then i will start a session() session_start(); $_SESSION['ls']="loggedin"; // ls stands for login status $_SESSION['id']=$row['id']; $_SESSION['user_name']=$row['user_name']; $_SESSION['email']=$row['email']; header('location : members.php'); die (" "); and will redirect them to members.php .... Everything is working fine... But in login.php i have written a code on the top... <?php if(isset($_SESSION['ls']) && isset($_SESSION['id']) && isset($_SESSION['user_name']) && isset($_SESSION['email']) ) { header('location:members.php'); die(" "); } ?> I want if a session is started and if user will access login.php they will automatically go to members.php But this script is not working... Iam not getting whats the problem... also i m not getting any error login.php or anything CODE WRITTEN ON THE TOP OF members.php IS : <?php session_start(); if(@$_SESSION['ls']!=="loggedin" ) // Checks if the person has done stage one (Registration.php) { header('Location: login.php'); //If they haven't done it, it sends them back. die (" "); } ?>

Yup cyberRobot as security point of view i am completely agree with you...

mjdamto i am not storing password as md5 hash in my database because i wont be able to know that what the password was... And i dont think that their is something ANTI MD5

Yup moderator... I tried it, the code written is correct ... Let me explain it to you.. The variable $userpass is already an md5 hash of the some string ... Now that string is stored in my databse.. Now to get the id associated with that string i need to write Select * from user_info where md5(user_pass)='$userpass'; And now my code is working fine i just made a silly mistake, the table name was actually user_info1 .. btw THANX everyone
