Re: [PHP] Session help please?

The reason I thought I could do this is because I can do $_SESSION['test'] = $_POST['test'] and be able to refer to just $test on other pages. This is because you probably have register_globals enabled, so the value of test in the user POST request is available to you as both: $_POST['test'] and $test It has nothing to do with you also setting $_SESSION['test']. Hope that helps.

RE: [PHP] Session Help
This is such an annoying thing. And it seems as though no one is willing to cover it in any manual, book or tutorial. Apparently the problem is that PHP sessions automatically set the no-cache header. So at the top of each script, after the session_start() function set header(Cache-Control: public); That will the trick. Actually it may work too well but at least your visitors won't get discouraged by that annoying message. -- Kevin Stone [EMAIL PROTECTED] -Original Message- From: Michael: Dave II, Electric Boogaloo [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 29, 2002 3:47 PM To: [EMAIL PROTECTED] Subject: [PHP] Session Help I'm having a little problem with my sessions on a website I'm programming for. After a user logs in, if that user follows a link, the variable information is being passed correctly, but when they hit Back, Internet Explorer gives a Warning This Page Has Expired error. Hitting refresh does fix this, but Forward/Back is such a common procedure that I'd like for this to work smoothly. Could someone tell me what I'm doing wrong here? Thanks in advance.

Re: [PHP] Session Help
PHP automatically calls the appropiate function instead if you. But consider that the save handler is not called on individual session_register functions, only when all output is gone, and the whole session - each registered variable - must be saved. manual Note: The write handler is not executed until after the output stream is closed. Thus, output from debugging statements in the write handler will never be seen in the browser. If debugging output is necessary, it is suggested that the debug output be written to a file instead. /manual - Original Message - From: phantom [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, November 30, 2001 10:10 AM Subject: [PHP] Session Help | I am trying to set my session data to be stored in MySQL so I am using | session_set_save_handler() which sets the six user-level session storage | functions (which I have already defined). | | Will session_set_save_handler automatically run the appropiate storage | function when required (like when i say session_register(Variable)) | --OR-- do I specifically have to run that function | (mysql_sessions_write(SID,$Value)) from my script when I want to save | info to the session table? | | I would appreciate any scripts anyone might have that would illustrate | how this works, the PHP manual and online examples I have found just are | not cutting it. | | Thank you.
