How to pass boolean variable of false in a URL

Question

I cannot work out how to pass a variable with a boolean value of false through a URL string. What is the correct method?

• domain/page?test=false
• domain/page?test=
• domain/page?test=0

Answer 1

URLs are strings and all values in a URL are strings. When you see i=0 in a URL, 0 is a string. When you see b=true, true is a string. When you see s=, the value is an empty string.

For those strings to take on another meaning—the integer 0 or the Boolean true, say—the server-side program must be told how to interpret them. Often web frameworks will make intelligent guesses as to the right type, or sometimes a type is declared explicitly in a model.

How you'll do it depends entirely on what server-side language and what framework, if any, you're using.

Answer 2

Like mentioned above, it's depends on the server-side language you are using as to how you will handle it. To add to the answer, if you want to pass a true or false in the URL as a parameter you can

running node on server

const whatever = JSON.parse(queryStringParameter)

running php on server

$whatever = json_decode(queryStringParameter)

Both options will give you a boolean type that you can use on the server.
