I am trying to register a new user on Drupal7 via services with JSON. Actually I am posting info from JAVA (android) with JSON format to the server with services module enabled. A sample successful JSON post is: 

    {
    "name": "erfan",
    "pass": "1234",
    "mail": "[email protected]",
    "status": "1"
     }

URL: [siteURL]/[endpoint]/user/register

I was successful creating users with basic info such as name,email,status.

I have added custom fields like field_address, field_phone, etc to the web site and want to send them via JSON to the server.

The problem is I can not figure out how to post these data to the server and couldn't find any documentation about it. My trial and error approach was not successful too, because I am not good in PHP coding. So please help me. Thanks.

    Could you edit the question and add one of the attempts? It'll be a bit easier to advise once we've seen the code. Entity fields are structured like $account->field_name[$language][$delta][$column_name] if that helps. An example for a text field might be $account->field_foo[LANGUAGE_NONE][0]['value']

Hope this will help you,

In Drupal 7 you can use the below JSON format to add custom fields(field_user_image)

{
    "name": "test",
    "pass": "password",
    "mail": "[email protected]",
    "field_user_image": {
        "und": [{
            "fid": "2"
        }]
    }
}

I have tried in my local and it is working fine.

  • Created new field UUID

    enter image description here

  • Calling the Service using Firefox poster add-on

    enter image description here

  • Code


  { 
    "name": "testuser123", 
    "pass": "testuser123", 
    "mail": "[email protected]", 
    "field_register_uuid": 
      { "und": 
        [{ 
          "value": "65C7DCA4-8F03-473C-9E8F-08B3F29E91AE" 
        }] 
      }
  }

I can able to create new user with the custom field

  • This doesn't seem to work. I'm using UUID Field, and want to create a user with a UUID, which is just a text field, really. { "name": "test", "pass": "password", "mail": "[email protected]", "field_uuid": { "und": [{ "uuid_field": "65C7DCA4-8F03-473C-9E8F-08B3F29E91AE" }] }} drupal.org/sandbox/Mile23/1326218

  • Thanks. But nope. :-) I suppose it's something to do with the way authentication is happening, or some other configuration problem.

  • I discovered I can create the user and then use PUT to update the field. The JSON above is correct, but it has to be a 2-step process. drupal.org/node/790416

This should be a comment, but I haven't enough reputation ...
When you create a user, you can only pass the fields that are shown in the registration form. Otherwise you'll need first to register the user and then update it with the new fields, as @paul-m said in his comment.

To show a field in the registration form go to

configuration->people->account settings-> manage fields
click the edit link of the desired field and check "Display on user registration form."

  • At the time of writing this answer probably it was not possible to update custom fields in one go, but now drupal.stackexchange.com/a/156404/11058 answer works for me.

The field value may have to be "flattened" in order for the user registration to work. In the example below, the field is a List (text) field with radio buttons for the widget.

  • POST ?q=[my-endpoint]/user/register.json
  • Content-Type: application/json

JSON data to POST:

{
  "name":"bob",
  "mail":"[email protected]",
  "conf_mail":"[email protected]",
  "pass":"secret",
  "pass2":"secret",
  "field_choices":"2"
}

This also works for radio buttons:

"field_choices":{"und":"a"}

However, when we use a select list widget on this same field, the JSON is formed like this:

"field_choices":{"und":[{"value":"2"}]}

The JSON above will not work for radio buttons, you'll get a 406 - Not Acceptable An illegal choice has been detected. Please contact the site administrator. This is a lesson and reminder that the Services module can sometimes be dependant on your field's widget when it comes to the JSON it expects.
