$_SERVER[REQUEST_URI] and page navigation

[phprock]

Hello,

I m getting problem in the following case..

I have page let say
code]
htp://localhost/index.php?file=cat
[/code]

It display all the records in all category wit page navigation.

My page navigatin url becomes like

 htp://localhost/index.php?file=cat&page=1
 htp://localhost/index.php?file=cat&page=2
.. etc

I want to send $sort paramter ... so it does not matter where you are you it will add sort paramater to the current url

ie.

<a href=$_SERVER[REQUEST_URI]&amp;sort=1>Sort by latest entry</a> <a href=$_SERVER[REQUEST_URI]&amp;sort=1>Sort by highest price </a>

But it keeps adding $sort paramter..

ie.

[url]http://localhost/motortrader/index.php?file=home&page=2&sort=2&sort=3&sort=2&sort=1&sort=2&sort=2[/url]

is there any way to solve. I am sorry If i could not explain it very well.

All I want is , where ever you are either in

 index.php?file=home  or
 index.php?file=home&page=1 or
 index.php?file=home&page=3

I just want to send $sort paramater.so i can requery the database depending one what sort you want.

 index.php?file=home&sort=1  or
 index.php?file=home&page=1&sor=2 or
 index.php?file=home&page=3&sor=1

If i use

<a href= $_SERVER[REQUEST_URI]&sort=1>Sort by ending date</a> | <a href= $_SERVER[REQUEST_URI]&sort=2>sort by highest price</a> .

it keeps adding $sort paramter when you click on the link ie,

[url]http://localhost/motortrader/index.php?file=home&page=2&sort=2&sort=3&sort=2&sort=1&sort=2&sort=2[/url]

Create a new variable, stripping out the sort parameter at the top of the page to use in your links.

$newLink = str_replace("&sort=".$_GET['sort'],"",$_SERVER['REQUEST_URI']);

Something like that should work...

[phprock]

$url = str_replace("&sort=".$_GET['sort'],"",$_SERVER['REQUEST_URI']);

echo"Sort by items:  <a href=\"index.php?file=home\">newly listed </a> |<a href=\"$url&amp;sort=1\">ending first</a>| <a href=\"$url&amp;sort=2\">lowest priced</a>| <a href=\"$url&amp;sort=3\">highest priced</a>";

My first page is

just index.php

and navigation and soriting
page is index.php?file=home

so if i m in url index.php?file=home it works however if i m in the index.php it does not work..

Any suggestions

Thanks

Okay, so you only want it when file=home?

So, same thing you're doing, just with a conditional

if(isset($_GET['file']) && $_GET['file'] == "home") {
   $url = str_replace("&sort=".$_GET['sort'],"",$_SERVER['REQUEST_URI']);
   echo"Sort by items: .....";//your text
}
