if statement questions

[toadeny]

Hi, i am trying to do a page in php at the moment with some if statements. I know this is possible , but how is it done.

a have a variable from the address bar, ill just call it var for now.

what i want to happen is, if there is nothing in the var then a section of that page loads stating plain text options for the user.

otherwise if the var has something in it, then pass on and load the rest of the page.

thanks in advance.

if(!$var){
include "somepage.php";
}else{
// do something...
}

That only works if register_globals are on. Just an FYI before you bash your head against the wall if it doesn't work as I have done.

You should use $_GET['var'] I think.

Well, I was assuming he had set $myvar = $HTTP_GET_VARS['myvar']; because he said he had a variable from the address bar, but yes your'e correct. Be VERY careful when using query strings, they're not secure worth anything. Validate validate validate!

It dosent matter if it is secure, its just to select a products category.

i have got round it now thanks.
