GET values from variables with [] in url

Question

I have a URL like this

?custom[weight]=1&custom[weight2]=2

If i use echo $_GET[custom[weight]] then it doesn't work. How do i retrive this value?

Answer 1

You should access it with $_GET['custom']['weight'] and $_GET['custom']['weight2']

You can check it with print_r($_GET) and you'll get something like,

Array
(
    [custom] => Array
        (
            [weight] => 1
            [weight2] => 2
        )
)
