global var vs session vs something else maybe? [message #169840] Tue, 28 September 2010 04:34 Go to next message

Hello,

I'm running a query in initialFile.php which then displays some
information on the page. Later, the user has the option of clicking on
a load button, which loads a map to display this information on a
Google map.

initialFile.php has a query (that I need sometime later) and this page
has a button which runs a javascript function in loadMap.js which
makes an AJAX call to another file ajaxFile.php (where I need the
query so I can run it again).
I don't want the user to be able to see the query through cookies or
anything unsafe for the site.

My question is the following, is there a way to create a global
variable in initialFile.php and then access it in ajaxFile.php ? If
so, how would I do it? I have tried and failed using several options.
Is it better to just use a session to pass that query?
Would you have any better ways of doing this?

Thank you so much!

Then use session, user will at most see the session key, no clue what values
may be stored.

I wouldn't really store the whole query in the session, but only the values to
be used in the query, that way you can do more with the values, like display
them or...

$_SESSION is the closes thing, you could store it on a file which you create
with the script, but that's kind of reinventing the wheel.

Session cookies. It's all in the manual.

I guess you're right. Using a session would be the best way. Thanks!
