Adding Varible to $php_self

is it possible?

[havoc]

Hey there i am currently writing a script where i need a varible page number system.

There are two ways the pages come up , under a gallery or catergory. One page controls the whole lot and since page numbers comes in all sections i have to setup varible page numbers. The problem is i am trying to add 1 extra varible to the $php_self command and it isn't working.

for eg: i go to this catergory

"index.php?mode=thumbs&catergory=pics"

i need to add page number to the end of this when the numbering starts.

i have tried <a href=\"$php_self" . "&page=$pageno\">$pageno </a> this produced - "index.php&page=1"

i tried making a varible and adding it too.
$link = $php_self;
$link = $link . "&page=$pageno";
this also produced "index.php&page=1"

Is there any way i can add my page to the end of the url?
the end result would look something like
"index.php?mode=thumbs&catergory=pics&page=2"

printf( "<a href=\"%s?mode=thumbs&catergory=pics&page=%d\">%d</a>", $_SERVER['PHP_SELF'], $pageno, $pageno);

i need to add the Page to the $php_self
the reason why i cant go <a href="$php_self?mode=thumbs&catergory=pics&page=2">$pageno</a>
is that there can also be a result such as "$php_self?mode=thumbs&gallery=Cheesewheels"

One is a catergory and one is gallery.

Which is why when i grab $php_self i need to add the page=2 to the end of the $php_Self ... i cant hard code in the "?mode=thumbs&catergory=pics". i hope that makes sense.

i guess i could just make it so both varibles are in there but it would be messy.

Thanks for the above reply though. :)

I'm not sure I'm understanding why you're trying to do, but if mode and catagory are variables as well, I'd use them as such. Why not try something like:

printf( "<a href=\"%s?mode=%s&catergory=%s&page=%d\">%d</a>", $_SERVER['PHP_SELF'], $_GET['mode'], $_GET['catergory'], $pageno, $pageno);

[ edit - a few typos fixed, guess it's late :) ]

ok this makes more sense i think .. i will give it a go tonight.

but what i was originally trying to so i take the current value of $php_self which could be a variety of things
eg "index.php?mode=thumbs&catergory=pics"
or "index.php?mode=thumbs&gallery=pics"

and just plop a &page=$pageno to the value of $php_self.

if i have to split it all up i will do that

I figured out a completely different way to do it :)

Or

printf('<a href="%s&page=%d">%d</a>',$_SERVER['REQUEST_URI'],$pagenum,$pagenum);

should work.
