Session Problems :(

[benbacardi]

I'm just getting to grips with PHP, and trying to figure out a way of making sure people are logged in, like using the session variables in ASP. But when I put session_start(); at the top of my home page, i get loads of warnings:

Code: Select all

Warning: session_start(): open(/tmp\sess_e2478c752cf8239fb5ba8e8b7dda89e6, O_RDWR) failed: No such file or directory (2) in C:\Program Files\Apache Group\Apache2\htdocs\test.php on line 3

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at C:\Program Files\Apache Group\Apache2\htdocs\test.php:3) in C:\Program Files\Apache Group\Apache2\htdocs\test.php on line 3

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at C:\Program Files\Apache Group\Apache2\htdocs\test.php:3) in C:\Program Files\Apache Group\Apache2\htdocs\test.php on line 3

Warning: Unknown(): open(/tmp\sess_e2478c752cf8239fb5ba8e8b7dda89e6, O_RDWR) failed: No such file or directory (2) in Unknown on line 0

Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0

can anyone help?

My guess is that this is very much related to this:-

In other words.... they are warnings... not errors and you can turn them off somehow.

thanks rob - have turned them off, but $_SESSION variables are not constant from page to page - they lose their value when you click a link - do you know why?

Are you sure you're using PHP 4.1 or later? $_SESSION cannot be used prior to PHP 4.1.

Also, do you have register_globals turned on in your php.ini? If so then you'll need to register your variables using session_register('myvar');

im using php 4.3.3, and i have tried it both registering variables with session_register and both with register_globals turned on in php.ini

i found this in php.ini:

; Argument passed to save_handler. In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.
; As of PHP 4.0.1, you can define the path as:
; session.save_path = "N;/path"
; where N is an integer. Instead of storing all the session files in
; /path, what this will do is use subdirectories N-levels deep, and
; store the session data in those directories. This is useful if you
; or your OS have problems with lots of files in one directory, and is
; a more efficient layout for servers that handle lots of sessions.
; NOTE 1: PHP will not create this directory structure automatically.
; You can use the script in the ext/session dir for that purpose.
; NOTE 2: See the section on garbage collection below if you choose to
; use subdirectories for session storage
session.save_path = /tmp

is that anything to do with it? it says Windows users have to change this - to what?

[Webforumz Staff]

To anything you choose... Eg: C:\temp
Just create that folder and change the path.

sessions are still not holding values...

ok, i've solved it guys. For some reason, PHP did not like me putting session_start(); at the top of my pages, so i decided to set the auto start session thingy in php.ini to 1 rather than 0, and that did the trick. ty for u help tho
