Define user as Guest – help

Copy linkTweet thisAlerts:
Oct 01.2005

I have on each page
script for session:

[code=php]
 session_start();
if(!isset($_SESSION[‘logged’]) or $_SESSION[‘logged’] != TRUE)
{
$_SESSION[‘caller’] = $_SERVER[‘PHP_SELF’];
header(‘Location: index.php’);
}
[/code]

How can I define user as guest. So, he can just look for pages and not redirect
to index.php? Please help. ?

@SheldonOct 01.2005 — you could have this in the top of each page

[code=php]
session_start();
if(!isset($_SESSION['logged']) or $_SESSION['logged'] != TRUE)
{
$_SESSION['caller'] = $_SERVER['PHP_SELF'];
header('Location: page.php?guest=yes');
}

[/code]then do a check on the page to see if guest is set.

@SheldonOct 01.2005 — Or better yet start a session as guest.


[code=php]
<?php
session_start();
if(isset($_SESSION['logged']) && $_SESSION['logged'] == 1) {
// DO NOTHING
}
else {
$_SESSION['guest'] = 'Guest';
//start session as a guest.
}
?>
[/code]

@bokehOct 02.2005 — [code=php]session_start();
if(empty($_SESSION['logged'])){ // if you are checking for boolean true this is all you need
$_SESSION['caller'] = $_SERVER['PHP_SELF'];
header('Location: guest_page.php');
exit; // after a redirect you need to exit so the script stops at that point
} // no need for an else statement

// page content here[/code]

@toplisekauthorOct 02.2005 — If visitor is redirected to start Guest page (welcome) I would like that each page which is marked as allowed to guest will be visable and visitor will be defined as guest.

What do you think can be changed your script? I have also LgIN page for registered users. I'm new to this. Need help.

@bokehOct 02.2005 — [code=php]print 'if you are a guest or a logged in user you can read this part';

if(!empty($_SESSION['logged']) and empty($_SERVER['guest'])){
print 'only members can read this part';
}

if(!empty($_SESSION['logged']) and !empty($_SERVER['guest'])){
print 'only guests can read this part';
}[/code]

@toplisekauthorOct 03.2005 — I would like that registered user can be also as Guest if he decides.

I will show in table what are possibilities:

Guest Non logged Logged

Non registered YES No NO

Registered YES YES YES


So, if registered user clicks on link in page

there will be $_SESSION['guest'] = TRUE;

How to do this with PHP? Please suggest.

I put in guest_page.php following code and Submit button does not work. Please help why.
[code=php]
<?
session_start();
echo 'If you would like to be just Guest please click on Submit&nbsp;';
?>
<FORM>
<br /><center><input type="image" name="guest" src="images/submit.gif" /></center>
</FORM>
<?PHP

if(isset($_POST['submit']))
{
$_SESSION['guest'] = TRUE;
$_SESSION['logged'] = FALSE;
}
else { $_SESSION['guest'] = FALSE;};
?>
[/code]

Success!
