Transferring variables form one page to another

[BabeWalls]

Is there a way that I can define a variable one one php page and then link to another page and this variable is remembered.

I know this is easily done when using a form but how is it done using normal links?

I'm not very experienced in php yet but I always do this by creating a cookie, using the setcookie() command.
Then you can refer to this cookie in another page as if you were referring to a variable.

Maybe there are far better ways, so I'll check back on other peoples replies to this message 🙂

setcookie() is one possibility.
Other options are:

Sessions:
use start_session() right at the top of each of your pages.
You can then declare persitent variables with $_SESSION["someName"] = someValue;
You can access these variables on every page as long as the session exists.
Usually, sessions use cookies to maintain state. In case no cookies are available, you might need (depending on your PHP configuration / version) to add "?".SID to every url on your pages.

URL Query Strings:
Simply attach the variable to your urls with the following syntax: yourUrl.php?firstVariable=....&secondVariable=.....

you might also want to read up on things like session, $GET, $POST, $_SESSION etc. on www.php.net

And of course, if you've got a more detailed question, just post it.

Hope this help 😉
