How URL works? And what is the relation with GET and POST?

Question

I have question, basic question I guess. But its important for me to learn more about web application.

I've ever seen a url with there are other words. for example: http://api.openweathermap.org/data/2.5/weather?q=Setapak&mode=xml

there is q=setapak&mode=xml. what it means? and what relationship with GET or POST?

when I try to create a simple page such which the code are:

    <?lc
put $_GET['number'] into number

put number
?>

and I run the url on the browser: livecode/nana/url.lc?number=1

it shows nothing. So I get confuse. Can anyone explain to me? Thank you..

There are lot of blogs and sites which describe GET and POST methods. You can refer — Nishanthi Grashia, Jun 03 '14 at 03:19

Get will transfer you Parameter Using URL all parameters will add to the URL ?number=1 this is one such example. it will carry number variable with value 1.

Post transfer parameters by attaching them to HTTP message body. Refer below link and you can get a good understanding about that.

You can't use single quotes in LC. use normal quotes around "number", and it should work.
