PHP questions...

Okay, I'm totally lost on the PHP thing. I'm trying to pass variables into my 'index.php' so that I can use a case statement to select which block of code to display in the main view. Currently it's showing all of them:

http://wizardcode.port5.com

Now, I have a switch statement in there that's supposed to display the pages based on the variable $page. How do I give this a value? I tried this (just a shot in the dark...), but it didn't do anything:

http://wizardcode.port5.com/index.php?s=&page=0

your server must not have render_globals on.
At the beginning of your code, put this line:

Code:

parse_str($_SERVER['QUERY_STRING']);

It'll parse the variable values into the proper variables. Cool, huh?

You can do this:

Code:

if (!empty($HTTP_POST_VARS['page']) || !empty($HTTP_GET_VARS['page']))
{
    $page = (!empty($HTTP_POST_VARS['page'])) ? $HTTP_POST_VARS['page'] : $HTTP_GET_VARS['page'];
}
else
{
    $page = '';
}

I don't understand what that does. Sorry I haven't had a chance to try the other code either. I have to upload with FTP and it's a lot more trouble to work on the site than it was on Angelfire. I need a real chunk of time, not just a half-hour here and there.

I hope you're not referring to my code, so blurg.

if (!empty($HTTP_POST_VARS['page']) || !empty($HTTP_GET_VARS['page']))

/*This part above just says if the POST or GET variables are not empty, do this code*/

{
$page = (!empty($HTTP_POST_VARS['page'])) ? $HTTP_POST_VARS['page'] : $HTTP_GET_VARS['page'];
}

/*The code above says if the POST variable has something in it, page equals that, if not, then it equals the GET variable.*/

else
{
$page = ''"; //Nothing, nar.
}

Hmm... I still don't understand the difference between POST and GET vars... Couldn't I just put $HTTP_POST_VARS['page'] right into the case statement?

POST variables aren't able to be input through the address bar, GET variables are.

in the url http://domain.com/index.php?var=8

var is the GET variable. POST are more secure, but GET allows the user to bookmark and such.
