Passing variables into functions and classes

Hi all,

Just a quick question. How do you pass a variable from a form into a function or class ? That is with register globals off and using something like $_POST['myVariable']. I'm new to all this stuff so please kind.


Thanks in advance,

Niall

Yes... with globals set to off, use this:

For post form method: $_POST['var_name'];
For get form method: $_GET['var_name'];

Or you can use a PHP special function that creates the variables for you, use this:

@import_request_variables("GP");

The @ symbol is to omit errors...
The G and P means: GET and POST.
Using this will make any form variable avaible at your script, even if globals are set to off.
You can even use the letter C too, that is for Cookies.
And don't forget, that if you use this, the variable name at your script will be the same name as the form field name. In example: if a form field is named: "txtZip" then you'll have a variable in your script named: $txtZip

Thanks for your reply Ramiro.
Sorry it took me so long to get back to you.

all the best,

Niall

Doesn't that just defeat the purpose of globals being off? Correct me if I'm wrong...

Not really, no r_g being off is to reduce the risks of variable poisioning - import_request_variables simply takes the GPC superglobals and effectively performs extract() on them all. There's no risk of variable poisoning this way.

But I'd still say stick with $_*.

Okay.... I wasn't sure what the main difference was. But as you said, I too, would rather stick with the superglobals!
