Ok, what I would do is either pass in an array of key/value pairs OR pass in
2 variables, the key name and the value.
$keyValuePairs["name"]="Company1";
$keyValuePairs["address"]="123 Main Street";
$keyValuePairs["city"]="Anytown";
$newURL = testPassVar("http://www.calevans.com",$keyValuePairs)
function testPassVar($url, $keyValuePairs) {
/*
* There here in the function you unwind the array and add each to the URL
in the form of
* $thisKey=$keyValuePairs[$thiskey]
*
*/
return $url
} // function testPassVar($url, $keyValuePairs)
A simpler method is to pass in a single key and value and let the function
add them and return you the newly munged URL.
function testPassVar($url, $key, $value) {
//won't work if it's the first pair. need to test for that!
return $url."&".$key."=".$value;
}
$newURL = testPassVar("http://www.calevans.com?test=one","name","Cal");

Hey Cal -
this makes sense but the thing is that different parts of the site will call
such a function and they will all want different variables attached to the
end -
I could do it some other way - but I wanted to know if there was some way of
doing it by sending the whole URL(incl. the variables) and letting them be
dealt with by the function.
Thanks,
Abe
