Complex object in a query string

Question

How can I have this structure in a query string?

"properties": {
        "list": [
            {
                "label": "bye",
                "value": "world"
            },
            {
                "label": "hello",
                "value": "mars"
            }
        ]
    }

I've tried it with properties[][list][label]=bye&properties[][list][value]=world&properties[0][label]=hello&properties[0][value]=mars and also with properties[][list][label]=bye&properties[][list][value]=world&properties[][list][label]=hello&properties[][list][value]=mars, none of them worked. I built them in php with http_build_query.

I need to have this structure in a query string because I have to send the data along with some other stuff with POST to a PHP site.

How about sending it as a JSON string? the newlines are just for human reading, you can just do it all in a single line and then use json_decode in PHP. — ChristianM

Well the problem is that I can't send it via PHP, instead I have to use something similar to cURL. — User2093587239023

I see two errors in your query string:

properties is an object, so there's no need to use [] to add elements.
list is an array, so you must use numeric indexes in the query string.

The correct query string is:

?properties[list][0][label]=bye
&properties[list][0][value]=world
&properties[list][1][label]=hello
&properties[list][1][value]=mars

(multi-lined for readability)
