Passing variables?

FoxhoundX

Okay, I have a question..I am making an RPG game site, and there will be MANY weapons. What I play to do is write them into a .txt file and use explode, then find $whatever[0] == 'weapon name', then get the price/damage/etc from there.

My question -

is there a way to send a variable (In this case, the weapon name), to another page?

would something like http://www.whatever.com/rpg/buy?name=Sword

work, where as $name would be equal to sword?

Just dont like all those big clunky form buttons :p

Passing GET information is very much possible in PHP, read this:

http://www.php.net/variables.external

GET can be passed via a form or other means, like writing it out in a link. Same difference.

Hmm, I do not see anything in there that relates to passing GET variables without a form.. 😕

The PHP manual isn't meant to explain how HTTP works, but it does give plenty of examples on how to retrieve GET information. Whether your GET information is passed via a form, or through a link, it doesn't matter to PHP one bit. ALL GET information ends up in the URL.

So pretend by passing information in the url via your links that you are using a GET form, it makes no difference at all.

Btw, that manual page should be restructered a bit to better show this is the case as the following sentence is kinda hidden:

Using a GET form is similar except you'll use the appropriate GET predefined variable instead. GET also applies to the QUERY_STRING (the information after the '?' in an URL). So, for example, http://www.example.com/test.php?id=3 contains GET data which is accessible with $GET['id']. See also $REQUEST and import_request_variables().
