hi problem solved because the path inside a function and the variable definition outside all i needed to do was adding (global) function to get the things to work like this // this is the variable i want to use as a directory definition $logger=$login_session; class UploadHandler { protected $options; function __construct($options=null) { // global function to allow the variable to work inside the function_construct // use this with any function you wanted the variable to work in global $logger; $this->options = array( 'script_url' => $this->getFullUrl().'/', // i used the variable as a folder path here and works fine 'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME'])."/account/".$logger."/",

i modified the code to write the slashes before and after file name like this 'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME']) . "/"."12345"."/", i did this because i thought the variable might not getting the slashes this works fine but again when i identify 12345 as a variable in the top of the same document its not working s.th like this $path="123445"; the code should be 'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME']) . "/".$path."/", but its not working why i have no idea any help

it didn't work the code posted by Pikachu2000 is good I'm sure but where should i write the value $path in this document i wrote it directly under <? php do i need a function or any thing else to identify $path or its ok to write it anywhere ? example : $path="12345";

I'll try this and give you the result Thank you pro

I left spaces to show you its not this " ;-)

hello i have a code to get some uploaded files from different folders i have users and i want each user session ( the username ) get his file from the server but simple thing here how to use a variable like $session_user in a path look at this code $FileName = "test.php"; $fh = fopen('./premium/$FileName', 'w') or die("can't open file"); i got this from other site but this doesnt work for me i have the path inside a function see this <?php class UploadHandler { protected $options; function __construct($options=null) { $this->options = array( // mysql connection settings 'database' => "ecf", 'host' => "localhost", 'username' => "root", 'password' => "99801277", 'script_url' => $this->getFullUrl().'/', 'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME']).'/12345/', 'upload_url' => $this->getFullUrl().'/files/', 'param_name' => 'files', // Set the following option to 'POST', if your server does not support // DELETE requests.

'.$path.' ', this didn't work how to get this variable inside this path ? please help .

problem solved what i did as some mates said the problem from session_start(); so i added this code to lock.php and remove all the other codes and include this file with every single php thank you very much

The $login_session isnt used any where else Actually im not that good in php im good at html more I used login_session to show the user in external page to say hellow ( user) but i needed the same result to get data from marks table i didnt have any other code with $login_session Im sure i miss understand something in this code and its about this value and this is why i need help because i got sick trying to solve it i really really thank you I will keep trying and inform you and if you want the whole source files i can upload them to you its not website its a school project

oh no it didn't fix it your code is good i replace my code and the whole site works fine but the graph still has the problem any fix

Thank you i will try your codes now Thank you again its great i will return ASAP

and another thing i didnt use session_start(); in Get_marks.php but it gives the result why the other file (mysql_graph_bar.php) can't git it ? is there any effect of including two phps in this php ? i spent masive hours trying to solve this

when i started it it gives an error in the top Notice: A session had already been started - ignoring session_start() in

hello i really need help i cant get session to work in a particular php file but it works with others here are the codes i'm working in mysql tables of student marks i want to allow all students to logon and each one see his greads with a chart i started with login.php login.php <?php include("config.php"); session_start(); if($_SERVER["REQUEST_METHOD"] == "POST") { // username and password sent from Form $myusername=addslashes($_POST['username']); $mypassword=addslashes($_POST['password']); $sql="SELECT id FROM users WHERE username='$myusername' and password='$mypassword'"; $result=mysql_query($sql); $row=mysql_fetch_array($result); $active=$row['active']; $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1) { session_register("myusername"); $_SESSION['login_user']=$myusername; header("location: users/panel.php"); } else { header("Location: invalid_login.html"); } } ?> then this will start a session in lock.php <?php include('config.php'); session_start(); $user_check=$_SESSION['login_user']; $ses_sql=mysql_query("select username from users where username='$user_check' "); $row=mysql_fetch_array($ses_sql); $login_session=$row['username']; if(!isset($login_session)) { header("Location: login.php"); } ?> then the result will be showed in auth.php which i included in the students' page to say welcome ..user... <?php include('lock.php'); print $login_session; ?> i have a table with the marks and i need to do charts and show marks from that table to show marks i used the following code and then include it in students page to see results get_marks.php <?php include("config.php"); // connect to the mysql server $link = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die ("Could not connect to mysql because ".mysql_error()); // select the database mysql_select_db($mysql_database) or die ("Could not select database because ".mysql_error()); $query = "SELECT id, sno, maths, english, physics, servicew, ast, defstudy, nav, other FROM Marks WHERE sno = '$login_session'"; $result = mysql_query($query); if (mysql_query($query)) { echo ""; } else { echo 'Incorrect Name: ' . mysql_error() .
