check if query string exists


Recommended Posts



I am wondering if there is way of checking if a query string exists (without any other string)


for example:




i can check if the string exits:


if($_GET[value] == true && $_GET[value2] == false){


however, there are a lot of combinations where "value" strings apears.

so is there a way of checking if ONLY one string exists?


hope you can help

I have tried checking Request["foo"] as well as Request.QueryString["foo"] and I get null for both. I have also tried populating a List with the values from the QueryString collection but as I mention below, it does not include the value.
