Passing variables

[Jolten]

Can someone please explain, or give me a link to understanding how variables are passed between pages with vbulletin?

I know the code to get the variable is similar to:

PHP Code:

globalize(array(
'var01' => STR,
'var02' => STR
)); 


but how does one pass the variable to the page? Is it just a matter of placing it with the url such as:

PHP Code:

http://www.domain.com?var01=yup&var02=nope 


or is there some other way?

Thanks, any guidance would be greatly appreciated.

Yes it is either attaching a ?foo=bar to the end of a file name or by submitting values through forms. Those are the only 2 real ways to pass values. Well there is cookies but other than with logins I wouldn't recommend messing with them.

The thing I struggle with is getting the actual page to pull the variables.

I know $_GET['var'] or $_POST['var'] but how does that relate to the serializing? is it replaced by the globalize array?

you gotta use the $_REQUEST['var']

PHP Code:

// globalize variables
globalize($_REQUEST, array(
    'perpage' => INT,
    'pagenumber' => INT,
    'g' => INT,
    'p' => INT,
    'do' => STR,
    'goto'
));

edit... ahh.. I'm starting to get it .. thanks sabertoothe!

Thanks!

yeah i guess you could do that though i would personally just go for

PHP Code:

// globalize variables
globalize($_REQUEST, array(
    'perpage' => INT,
    'pagenumber' => INT,
    'g' => INT,
    'p' => INT,
    'do' => STR,
    'var' => STR
    'goto'
)); 


that way $var is arleady = $_REQUEST['var'] and has been checked to make sure it's either a string or int.

but in good coding practices you'd go

PHP Code:

$var = stripslashes($_REQUEST['var']);

You mean addslashes, assuming you're manipulating the database.

yup got it perfectly. I just couldn't wrap my mind around the globalize and I wasn't using $_REQUEST. But it's all fabulous now. Thanks for the help guys. Erwins form to thread/email/post just got 500% better
