PHP session variable

**ronnil** · Jun 6 '07, 09:57 AM

try to echo out session_id() just below your session_start() statement. If those two are not the same, you got a problem with your browser starting a new session for each request.

Just for eleminating that possibility

Why don't you post the complete scripts for both the pages here in the forum.

Hi ajaxrand, I did post the complete code above but will post it again for easier reference.

first page:
<?php
session_start() ;
$_SESSION['session_var'] = "testing";
?>
<html>
<body>
<p>This is a test of the sessions feature
<form action="session Test2.php" method = "POST">
<input type="text" name="form_var" value ="testing">
<input type="submit" value="Go to the next page">
</body>
</html>

second page:
<?php
session_start() ;
echo "test ".$session_ var;
?>
<html>
<body>
<?php
$session_var = $_SESSION['session_var'];
$form_var = $_POST['form_var'];
echo "session_va r =".$session_var ."<br>\n";
echo "form_var =".$form_var."< br>\n";
?>
</body>
</html>

This is the output:

test session_var =
form_var =testing

I also did try that and came with a null result. Any settings that I can check with the browser?

do you mean that session_id() is null? in that case your session is not registered at all.

I actually don't know how to set that configuration, since I've never had that problem myself :D

Double check this parameters with your configuration settings under your php.ini.just go for a phpinfo() again.

in each and every line this is the format.
Directive - Local Value - Master Value
session.auto_st art - Off - Off

Code:

session.auto_start    Off    Off
session.bug_compat_42    On    On
session.bug_compat_warn    On    On
session.cache_expire    180    180
session.cache_limiter    nocache    nocache
session.cookie_domain    no value    no value
session.cookie_lifetime    0    0
session.cookie_path    /    /
session.cookie_secure    Off    Off
session.entropy_file    no value    no value
session.entropy_length    0    0
session.gc_divisor    100    100
session.gc_maxlifetime    1440    1440
session.gc_probability    1    1
session.hash_bits_per_character    4    4
session.hash_function    0    0
session.name    PHPSESSID    PHPSESSID
session.referer_check    no value    no value
session.save_handler    files    files
session.save_path    C:\DOCUME~1\PRARTH~1.PC\LOCALS~1\Temp    C:\DOCUME~1\PRARTH~1.PC\LOCALS~1\Temp
session.serialize_handler    php    php
session.use_cookies    On    On
session.use_only_cookies    Off    Off
session.use_trans_sid    0    0

I think I had all the configuration setup well. Here's what I have in my file:

[Session]
session.save_ha ndler = files
session.save_pa th = "C:\Temp"
session.use_coo kies = 1
session.name = PHPSESSID
session.auto_st art = 0
session.cookie_ lifetime = 0
session.cookie_ path = \
session.cookie_ domain =
session.cookie_ httponly =
session.seriali ze_handler = php
session.gc_prob ability = 1
session.gc_divi sor = 1000
session.gc_maxl ifetime = 1440
session.bug_com pat_42 = 0
session.bug_com pat_warn = 1
session.referer _check =
session.entropy _length = 0
session.entropy _file =
session.cache_l imiter = nocache
session.cache_e xpire = 180
session.use_tra ns_sid = 0
session.hash_fu nction = 0
session.hash_bi ts_per_characte r = 5

Check this line under your php.ini
session.cookie_ path = /
in yours its "\"
