couldnt retrieve cookie value!!

[kenny_oh]

i have set the userID and password to cookie but when i want retrieve it, i cant get the value...why?

set cookie:

Session_start();
 
if (numRow > 0) then
      $_SESSION["usr"] = username;
      $_SESSION["pwd"] = pss;
      'do stuff
} else{
      'do stuff
}

Retrieve cookie:

Session_start()
 
       $usr = $_SESSION["usr"];
       $pss = $_SESSION["pwd"];

If you check in your cookies folder do you see the cookies you've set? Depending on your browser and/or ineternet security software settings they may be blocking your cookies from being set as well. HTH

[kenny_oh]

still cannot retrieve value

[lintz]

Have the cookies been created if you look in your cookies folder?

[kenny_oh]

i hv create a folder for store the cookie(all setting is done for path to save the cookies) ,but it still couldnt save the cookie in the folder

[kenny_oh]

this is the error message after i login and set the session

Post your code as it will help us to determine what the problem is.

<?php
 
    $adminUserID = $_POST['txtAdminUserID'];
    $adminPass = md5($_POST['txtAdminPass']);
 
    $host ="localhost";
    $dbname = "Broadcast";
    $dbpass = "";
 
    $connection = mysql_connect("$host", "$dbname");
    $db = mysql_select_db("$dbname", $connection);
 
    $results =  mysql_query("select * from tblAdmin where UserID ='$adminUserID' and Password ='$adminPass'", $connection);
    echo mysql_error();
 
    session_start();
 
    if (mysql_NumRows($results)>0){
 
    $_SESSION["adminUID"] = $adminUserID;
    $_SESSION["adminPass"] = $adminPass;
    
?>
 
    <script language = "JavaScript">
    document.location.href = "HomePage.htm";
    </script>
 
<?php
 
    } else {
        echo "Wrong !!";

You need to find the session.save_path setting in php.ini and set it to a valid directory otherwise PHP cannot save the session data.

[kenny_oh]

ya...i have change the path to c:\webCookies and created a folder named "webCookies".......and display the post #6 error

[visualAd]

The error in post number 6 says that the save path is "\tmp" are you sure that the script is using that php.ini file?

Call phpinfo(); to check that it can find php.ini too.

[kenny_oh]

hmmmm.....same problem!! i alr check the session_savepath is set to c:\webCookies

[visualAd]

phpinfo() will tell you which php.ini file is being used, if any.

[kenny_oh]

type like this??

echo phpinfo();

[visualAd]

No just:

phpinfo();

[kenny_oh]

it locate in C:\WINDOWS\php.ini .........what i need to do? change the save.path to this or .........??

[visualAd]

Well where is the php.ini you are editing? If it you have not already copy it into C:\windows

[kenny_oh]

i edit the php.ini in php inside php folder..........what not really understand what u mean?

First thing, that's not cookies, that are sessions.

<?php
session_start();
session_register("yourVar");
$_SESSION["yourVar"] = $_POST["txtAdminUserID"];

when you use $_POST['txtAdminUserID'] if the value of txtAdminUserID has spaces it will just read the first part untill the space and the rest of the value will be ignored.

Second: cookies:

#########-----> Set cookie

http/1.0 200
Content-Length: 1276
Content-Type: TEXT/HTML
Date: True, 06 Nov 2001 04:12:49 GMT
Expires: True, 06 Nov 2001 04:12:59 GMT
Server: simwebs/3.1.6
Set-Cokie: animal=egg-laying-mammal

It's donne like:
<?php
setcookie("vegetal", "rice", time() + 3600, "/", "localhost", 0);

if (isset($_COOKIE["vegetal"])) {print $_COOKIE["vegetal"];}
?>

3rd:
Be sure that exist:
C:\Myserver\www\tmp
or C:\tmp

4th:

$results = mysql_query("select * from tblAdmin where UserID ='$adminUserID' and Password ='$adminPass'", $connection);
That's wrong!
String are compared using LIKE

$results = mysql_query("SELECT * FROM `tblAdmin` WHERE UserID LIKE \"$adminUserID\" and Password LIKE \"$adminPass\"", $connection);

[visualAd]

i edit the php.ini in php inside php folder..........what not really understand what u mean?

copy C:\php\php.ini to C:\windows\php.ini then your problem will be solved

[snappel]

Is 'session_register("yourVar");' necessary? I've just posted a thread with a similar problem, except the $_SESSION variables are set but can only be retrieved from one page.

Also Kenny_Oh, it might be wise to validate the data the user puts in the form, bearing in mind your code is open to SQL injection attacks.
