Question

I want to add elements to JSON object.

{"email":"[e-mail]",
 "password":"utheu",
 "meta":
       {
         "screen_resolution":
                         {
                          "height":1080,
                          "width":1920
                         }

Above are the parameters. I want to add email, password and meta elements to JSON Object. I was able to add email and password but cannot successfully add the meta element.

Answer 1

It looks as if you forgot a couple of closing curlies

{"email":"[e-mail]", 
 "password":"utheu",
 "meta":{"screen_resolution":
           {"height":1080,"width":1920}
         }
 }

is valid JSON, you can browse it here by copy/pasting it in!

Agreeing with Marc B, modifying a JSON string directly is risky!

Good luck!
