Variable Flag ***Please Help*** 1

[chuckbridges]

How do I create a temporary flag variable say $flag
that can be checked from one page to another using an if ($flag=="1"){ statement. I dont want to save it in the database but I still want to flag it and unflag it from time to time...



Thanks

Chuck

Use sessions.

At the beginning of each script (before anything is output to the screen), put the statement:

session_start();

Where you want to set your flag to TRUE, use:

$_SESSION['flag'] = TRUE; // or anything else

Where you want to test it:

if (isset($_SESSION['flag']) && $_SESSION['flag']))
// do something

To unset it:

unset($_SESSION['flag']);

More information about sessions can be found at

http://www.php.net/session

chuckbridges,

Are you simply trying to pass a variable value between different pages? You can do this by simply passing the value in the anchor tag.

<a href="filename.php?flag=1">text</a>

If you do it on the URL, you will be subject to user manipulation of the flag and you better have very tight controls over what the variable is allowed to contain.

If you use SESSIONS, user will not be able to (easily) change the value.
