Will you know exactly how many GET arguments you will have? If you do, then you can use a foreach loop to split the GET arguments by key and value and manipulate it like that.

example:

foreach($_GET as $key => $value)
{
     echo 'Key: ' . $key . '<br />';
     echo 'Value: ' . $value . '<hr />';
} 

That would print your GET index and the corresponding values

thanx a lot i solved.....
the problem was that i was tired
take a look at this $_GET game

function News_console() {
$page = $_GET["page"];
$act = $_GET["act"];
$_SESSION["p"] = $page;
$_SESSION["a"] = $act;
$p = $_SESSION["p"];
$a = $_SESSION["a"];

if($_GET["co"] == 'open') {
$_SESSION["open"] = 1;
} 

if($_GET["co"] == 'close') {
$_SESSION["open"] = 0;
} 

if($_GET["ord"] == 'category') {
$_SESSION["cat"] = 1;
$_SESSION["user"] = 0;
$_SESSION["date"] = 0;
} 

if($_GET["c"] == 'user') {
$_SESSION["cat"] = 0;
$_SESSION["user"] = 1;
$_SESSION["date"] = 0;
} 

if($_GET["ord"] == 'date' OR 
$_GET["co"] == 'close') {
$_SESSION["cat"] = 0;
$_SESSION["user"] = 0;
$_SESSION["date"] = 1;
} 

if($_GET["open"] == '1') {
$_SESSION["o"] = 1;
$o = $_SESSION["o"];
} else {
$_SESSION["o"] = 0;
}

koobi,

instead of using

foreach($_GET as $key => $value) 

Try using this instead

echo '<pre>';
print_r($_GET);

Yeah I use that when I want to see what a variable contains, I also use var_dump() to view the types as well but you can't manipulate a string using print_r()



reminder, I just quickly skimmed through your code...it's best that you first strip_tags() and then trim() any variables that can be manipulated by the user such as $_GET, $_POST (and $_REQUEST if you use that instead). Just don't ever trust user input.



Example:

 if(empty($_GET) === FALSE)
 {
     foreach($_GET as $key => $value)
     {
         $_GET[$key] = trim(strip_tags($value));
     }
 } 

So if you entered a URL like index.php?page=<script>someScriptHere</script>

After you run it through that snippet, $_GET['page'] would only contain 'someScriptHere' without the script tags.

Hi,
I'm new with PHP. When do I use $_GET and $_POST and what is the difference between the two?

Thank you in advance,

JOzin

Jozin - this thread has been solved, and what your trying to ask is something completely different.

You need to ask you question in a new thread, that way people can see what your trying to ask.

Thanks

Rather than using all of those if's you could probably clean up the code by slapping them in switch structures. I guess it's a matter of personal taste, I just think using switch() makes the code much cleaner to read.

I used to be an if / elseif fan myself... of course I used to be a 'tables' pusher too!

Yeah I have to agree that switches are better, especially because it's faster.

thanx for replies!
so u think switch is better!
i usually use switch for other stuff!
can u please show me some short example how to introduce switch into this "if $_GET" game!
thanx in advance!
