Re: url rewriting within sessions - confused newbie needs help

Mike, I hope you mean session_start(). Yes, I did. Getting a bit dyslexic nowadays. Well, you would, because PHP would use the value from the PHPSESSID= URL parameter. ... except that on the second call, the url (as displayed by the browser) does not contain the PHPSESSID parameter, yet I am still able to retrieve the session variables correctly ... My immediate reaction to this is that session.use_cookies must be set to 0 (or Off) in your php.ini (or equivalent). Have you checked this? If it looks correct, what does a phpinfo() page show? php.ini contains the following settings: [Session]

session.save_handler      = files
session.save_path         = /tmp
session.use_cookies       = 1
session.name              = PHPSESSID session.auto_start        = 0

session.cookie_lifetime = 0

session.cookie_path       = /
session.cookie_domain     =

session.serialize_handler = php

session.gc_probability    = 1
session.gc_maxlifetime    = 1440
session.referer_check     =
session.entropy_length    = 0
session.entropy_file      =
session.cache_limiter     = nocache
session.cache_expire      = 180
session.use_trans_sid     = 1
url_rewriter.tags         = "a=href,area=href,frame=src,input=src,form=fakeentry"

In phpinfo(), the "local value" matches the "master value" for all entries, and match the entries in php.ini. I appreciate that this issue isn't a big deal - but I had hoped to understand php well enough to tell the difference between a "bug" and a "feature". If it would help, I could send you the url for the page? (password protected) Peter Ford, Mike [LSS] wrote:

Mike, Thanks for the additional explanation, and I understand the sequence of events as you described. However, please bear with me a bit - the results I am getting do not quite match your explanation. Let me clarify what I am doing: I have a page (index.php) which starts out by calling start_session(),

I hope you mean session_start().

then emits some html code containing some form variables for search criteria. After the form variables, I have a "submit" button that refers to index.php. Following that, I have php logic that extracts the search criteria (if set) from $HTTP_POST_VARS, performs a MySQL query, then creates a table of results (if any); one of the table entries contains a <a href= link to determine which row the user selected. The first time I load the page, I assume the session is created by start_session(), and the cookie is sent to the browser. When I click on the "submit" button, the page is reloaded - I assume with the session active - as per your explanation. According tho the documentation I have read, the second time the page is loaded, start_session() will simply reuse the existing session parameters. At this point, the browser should already have the cookie - if it did not, I would not be able to retrieve the session variables

Well, you would, because PHP would use the value from the PHPSESSID= URL parameter.

- but the url links in the table are still rewritten. I do not understand why.

My immediate reaction to this is that session.use_cookies must be set to 0 (or Off) in your php.ini (or equivalent). Have you checked this? If it looks correct, what does a phpinfo() page show?
