Can you share a variable in two seperate

[Anon]

Hi,

I have two scripts running in two seperate frames in the same browser. I was wondering if there is a way I can share a variable between the two scripts. I just need to do something simple like set a flag true/false.

Thanks,

Are you talking javascript or php?

If you are talking about PHP, then you should be able to start a session and register the variable with session_register() - it should then be available to any PHP pages that call session_start() at the top.

Thanks Will, I was just reading about that. So in the session I register it, I can modify the variable. In the session I call session_start(), I can only view the variable or can I modify it there too and the change will reflect in the other session?

As long as both frames have called the session_start() function, they should be using the same session... the variable can be read, modified, deleted, etc by any PHP process running in the same session. You can check to see if the variable has been registered by using the session_is_registered("variable_name") function.
This will let you know if the variables are accessible to both frames. I would perform some read/write operations to the variable, and print out the values at each stage of the read or write (in both frames) to make sure that they are using the same variable.

Good luck!

Will,
I tried this:
script 1:
<?php
session_start();
$fileFlag = false;
session_register(SfileFlag);
?>

and script 2:
<?php
session_start();
?>

both placed at the top. Maybe I forgot to mention that my script run simultanesly and script 2 depends on script 1. Well, when I run it like this, script 2 runs first, when it is done, script 1 start, which is not what i want.

Other ways to do this...could I make a static class that has just 1 variable?

Is there a particular need to use frames? I have found that while frames decrease loading for the client, they become increasingly harder to code, given all the communication that needs to happen between them. When this becomes more complex, javascript is frequently used to fill this need, which is something that should not be relied on for basic functionality of a site.

You may look into doing nested tables, and using the include/require functions.

Just my $.02
