?p=2 with $_SERVER['REQUEST_URI']

[XeroXer]

Hi there!

I am making my whole menusystem with ?m=1&p=2&f=folder

I am doing this with linking to $_SERVER['REQUEST_URI'].

The problem is that if m=1 is in the URL and I click a link with m=2 it is also entered into the URL.

So I have both 1 and 2 and the site doesn't work.

Or the problem that if m=2 and I press a link that goes to p=3 it has to add the & between them.

 

Can I check if the URL contains a m=, p= or f= and depending on what link is pressed replace the number/text or append it with a & at the end of the URL.

 

Hope that someone understands my problem...

Why are you using REQUEST_URI and not the query string $_GET?

Well the problem is that I want to replace the number in the URL if it's already there.

And if it's not I want to add a & and then enter the new.

If none of them exists I want to add a ? and then the code.

 

If a user goes to http://www.test.com/mysite/ and they click a link to my gallery.

The URL then goes to http://www.test.com/mysite/?m=2 that is my gallery.

They then select a subcategory in my gallery to my vacation pictures.

The URL then goes to http://www.test.com/mysite/?m=2&p=1 that is my gallery with the subcategory vacation.

In that gallery they select the folder Ibiza2006 and the URL goes to http://www.test.com/mysite/?m=2&p=1&f=Ibiza2006

 

If they now select a different gallery say London2003 the URL becomes http://www.test.com/mysite/?m=2&p=1&f=Ibiza2006&f=London2003

And it doesn't work.

I can also select main section such as my guestbook and the URL goes to this:

http://www.test.com/mysite/?m=2&p=1&f=Ibiza2006&f=London2003?m=3

* note the ? and not & *

All this is because I use REQUEST_URI and just add the ?m=1, &p=2 or &f=folder.

Can I somehow search the REQUEST_URI for m=, p= and f= ?

And if the one I am trying to enter exists it replaces that number and if none of them exists it adds a ? in the start.

And if another one exists but not the one I am trying to enter it adds a &.

 

 

( I know that this can be hard to understand but I so need your help. )

I understand now, and what you're trying to do is standard enough but you're doing it in a rather roundabout way.

Now, what you would do is:

$m = (( isset($_GET['m']) )?( trim($_GET['m']) ) '' ));
$p = (( isset($_GET['p']) )?( trim($_GET['p']) ) '' ));
$f = (( isset($_GET['f']) )?( trim($_GET['f']) ) '' ));

 

And now you can work with, and check the different variables.

 

if( $m != '' )
{
   $newp = '2';
   echo '<a href="?m='.$m.'&p='.$newp.'"> ... </a>';
}

 

I hope you get what I mean which is that you should re-construct the URL from the data you already have, not keep adding parts to the URL.
