[PHP] session management
hi! i need to maintain session state in my php application. i further need to be able to distinguish between admin levels and user levels and thus the session also needs to keep this info (ie, whether person has logged in as admin or user) any ideas how to do it. thanks -- ajay --- Who Dares Wins - This mail sent through IMP: www-mail.usyd.edu.au -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] session management
hi! well i do have a MySQL database. The scenario is this, i dont want to use cookies or do any URL rewriting. i'm looking for something that mirrors J2EE's Session object that contains information about the user, their security level(user/admin etc) and this information can then be verified before each request. There would ofcourse be an expiry on the object. Is there a prewritten framework/class to handle this? thanks regards -- ajay --- Who Dares Wins - This mail sent through IMP: www-mail.usyd.edu.au -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] session management
have a user bean, and then session.setAttribute("user", userBean);
do session.getAttribute("user") and validate before processing every request.

[PHP] PHP REDIRECT
hi!
i'd like to redirect a person to another page but after a certain time interval

like the person to go to this page, stay there for like 10 seconds and then be
redirected to the index page.
i was using header("url") to redirect the user.
but how do i get that to happen after a certain time interval.
thanks

[PHP] redirecting
hi!
after having trawled through many google articles, i've been told that the best
way to redirect a person is using header("Location:url");
the problem is, i have form that is posted to another php script. This script then
processes the form and then writes up a html page and includes in that page any
warnings etc.
i want the user to have say 5s to read that page and then be redirected to
another page.
so i have something like
//process form
//write page
sleep(10);
header("Location:blah.php");
the problem is i get an error when the script gets to the header part, the error
being
Warning: Cannot modify header information - headers already sent by (output
started at c:\program files\apache
group\apache\htdocs\usydbasketball\subscribe_mailing_list.php:6) in c:\program
files\apache group\apache\htdocs\usydbasketball\subscribe_mailing_list.php on
line 67
so how do i workaround that?
thanks

[PHP] Query regarding temporarily-uploaded files
Hi all. I have a requirement, wherein I need to allow vanilla uploads of files to a HTTPD server. Any client can upload any number of files (one at a time). Also, there is just one directory, where the files get stored "finally" (that is, after being copied from the temporary location, via "move_uploaded_file") Also, I have been able to get the simple file uploading running via PHP, by picking up one of the numerous "Hello World" examples available :) Now, I am facing the following use-case :: 1) User 1 starts uploading a large file, say "big_file.avi". 2) Meanwhile, user 2 also starts uploading a (different) file, but with the same name "big_file.avi". In an ideal scenario, user 2 should be prompted with a message, that a file of the same name is already being uploaded by someone else somewhere. Is there a way to do this? ( Note that, had the user 2 started uploading AFTER user 1 had finished with the upload, we could probably modify the PHP-script at the sever-side, to let user-2 know that a file of the same name already exits. But I am failing to find a solution, when the user 2 starts the upload WHILE the large file of user 1 is in the process of completing uploading). Any way the issue may be solved? I will be grateful for any pointers :) Regards, Ajay -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Query regarding temporarily-uploaded files
Thanks Jim and Anthony. Jim, You are right, your solution is doable. But one thing I am a little skeptical about, is what would be the percentage of the people willing to suggest a new name "immediately", versus the percentage of people who would like to cancel the current upload, and come back "later" after walking and coming up with a new name. Anyhow, let me sleep over it :) Anthony, your solution is really a special case of Jim's solution :) Thanks guys for the quick replies; I am obliged, really.

[PHP] How to send "post"-variables in a "Location" header
Hi all.
I have a scenario, wherein I need to do something like this ::
###
$original_url = "/autologin.php";
$username = "ajay";
$password = "garg";
header('Location: ' . $original_url);
###
As can be seen, I wish to redirect to the URL "autologin.php".
Additionally, I wish to pass two POST key-value pairs :: "user=ajay" and
"password=garg" (I understand that passing GET key-value pairs is trivial).
Is it even possible?
If yes, I will be grateful if someone could let me know how to redirect to
a URL, passing the POST key-value pairs as necessary.
Looking forward to a reply :)

[PHP] Re: How to "download" a multi-part file at the "server" side?
I just came across http://www.w3schools.com/php/php_file_upload.asp, and
tested it..
It works fine, when the file is uploaded via a form.
It does seem that the client-method might indeed play a role.
Here is my Java code for uploading the file ::
###
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION,
HttpVersion.HTTP_1_1);
HttpPost httppost = new HttpPost(URL);
File file = new File("/path/to/png/file.png");
// Send the image-file data as a Multipart-data.
MultipartEntity mpEntity = new MultipartEntity();
ContentBody cbFile = new FileBody(file, "image/png");
mpEntity.addPart("userfile", cbFile);
httppost.setEntity(mpEntity);
HttpResponse response = httpclient.execute(httppost);
###
Any ideas if making a change at the client (Java) OR/AND server (PHP) might
do the trick?
