Let's say I have a table with links in the headers for sorting each column. I want to
carry the sort variable along in the $_GET array, and I need to be able to pass other
variables to this same page, also using the GET method. My trouble is when I need to
append a new variable to the REQUEST_URI -- I need to detect whether a QUERY_STRING
has already been passed, so I won't use "?" when I need "&" in the URI. Here's my
clunky attempt:
<a href="<?php
echo $_SERVER['REQUEST_URI'];
if ($_SERVER['QUERY_STRING'] && !$_GET['newVar']) {
echo "&newVar=1";
}
else if (!$_SERVER['QUERY_STRING']) {
echo "?newVar=1";
}
?>
">link description text</a>
Please tell me there is some way to just append to the query string without checking
it first...
