adding variables to search

[wwwfilmfilercom]

if i have a line such as:

http://www.site.net/index.php?s=1

in my browser and i want to be able to click on another link in my website and end up with:

http://www.site.net/index.php?s=1&t=2

what is the correct method to do this via an anchor tag?

i tried:

<?php echo $PHP_SELF;?>?t=<?php echo $tnum;?>">

but as you will know that only returned:

http://www.site.net/index.php?t=2

so what is the correct way? (without using cookies if possible)

many thanks for your help,

Im not sure what you asking, but here is how you add another variable:

<?php echo $PHP_SELF; ?>?t=<?php echo $tnum; ?>&amp;s=<?php echo $snum; ?>

what i mean is that

if my url is:

http://www.site.net/index.php?s=1

this:

<?php echo $PHP_SELF; ?>

still = http://www.site.net/index.php

ie.

<?php echo $PHP_SELF;?>?t=<?php echo $tnum;?>">

will just do:

http://www.site.net/index.php + $t

but i want to add $t onto whatever the url is (and keep any other variables already there intact)

hope that makes sense,

Use the $_SERVER['QUERY_STRING'] variable.

Validate all variables in $_GET and then use the results to generate a new query string for the hyperlink.
