[PHP] $_SESSION variable gets lost on FORM action
Hi,
I'm working on a website and one of the features that I've implemented
so far is the user timeout.
Every time that a user browses to a different page, the variable named
$_SESSION['user']['lastactive'] is updated to the current time.
However, before that, my PHP scripts check if the session for this user
had timed out or not...
The script that checks that is named session.php and it is included in
every file. If it detects a timeout, it sets a variable
$_SESSION['form']['errors'] to a string ('Your session has expired...
Bla, bla, bla...') and then redirects to the login.php and the user will
see that he his being asked to login again for the reason displayed.
Everything works great except in one situation... If the timeout period
happens when the user is filling a form, the action that it executes
(process.php) will also include session.php and it sets the error string
but when it redirects to login.php the $_SESSION['form']['errors']
variable is empty...
Can anyone help me with this?
Thanks

You must be unsetting the individual $_SESSION['form']['errors'] variable
or the entire $_SESSION array somewhere in there.

Hi Davis, thanks for the reply.
I think that I've found the problem... But if you (or anyone else) can
confirm I would appreciate.
Sometimes in my code I use the Header('Location: index.php?var=value');
and I've found out (I think) that when one of these headers are executed
by PHP, the rest of the script gets executed.
I'm thinking that this is the problem because I've eliminated all the
occurrences where the SESSION var was cleared until only one exists and
it was after a Location Header.
I've put an exit(); after the header and the problem was gone... :)
Is this the correct PHP/HTML behavior or is there another problem? Am I
supposed to put an exit(); after a header Location to make sure that
no more code gets executed?
Thanks

The example on the manual page for the header() function says as much (http://php.net/header), you read that right? ?php header(Location: http://www.example.com/;); /* Redirect browser */ /* Make sure that code below does not get executed when we redirect. */ exit; ? -Stut Well, I feel like a du***ss! No, I hadn't read that. I promisse, and this one is to keep, I won't post to this list again without dedicate enough time to the problem, at least to read the manual. Anyway, thank you for confirm what I should have known in advance and also for remembering me that PHP developers have a PHP manual for PHP users...

Re: [PHP] email validation string.
1. Why did you remove the backslash? (the original was correct) I have a regular expression tester plugin in firefox and it validates Ok with the expression he provided. If I add the second (original) backslash it won't validate emails anymore. Also, from my little knowledge of Red.Exp. the backslash will escape special chars. In this case the backslash will escape the dot to match only a dot and not all chars... This my way of seing it... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] email validation string.
1. Why did you remove the backslash? (the original was correct) I have a regular expression tester plugin in firefox and it validates Ok with the expression he provided. JavaScript is *not* PHP. As far as I can read, I never talked about JavaScript... Maybe the fact that I talked about a browser made you think I was using Java. NO! I'm not. This is a php list and I gave my answer based on that. This plugin I was talking about uses PHP/5.2.0 In either case... Aren't both expressions supposed to validate an e-mail?? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] email validation string.
Where can I check out the plugin? Maybe I shouldn't have mentioned plugin and firefox... It's not a plugin for firefox like other firefox's plugins... In fact, when I downloaded somewhere arround the web the name of the thing (won't call it plugin again) was Site Programmer Plugin Assistant (or something alike) and it's just a bunch of php scripts that run as a local site... That's why I said that the plugin was using PHP/5.2.0 because that's the php version I have installed. It needs Apache with PHP support to work and the php code it uses is a form that processes a text field and do a ereg($Pattern, $Text) on an if statment that outputs Match or No Match. Meaning pure PHP (in my case v5.2.0) For a real Firefox plugin that shows the matched part of the text in real time as you change the pattern, you can search for a plugin (a real one) named Regular Expressions Tester. I don't have it but you can search http://www.mozilla.com for it. Wait... https://addons.mozilla.org/firefox/2077/ this is the homepage for the plugin. However, I don't know if this uses Java(script) or what... About what I asked in my last post... In php, if you have a string like $Text=[a-zA-Z]+\\. php will save it like [a-zA-Z]+\. because the first backslash is escaping a special character which is the second backslash but if you have the string $Text=[a-zA-Z]+\. php will save it the exactly the same way because even that the backslash is used to escape special characters, there is no special char after it. It's just a dot. So the string gets stored the same way. Also it doesn't get different with quotes or double quotes. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
