People Picker Get using sp.js & Update(Single User & Multi User) using REST API IN SHAREPOINT 2013

When you try to create/update list item just check the fields details of the list using the REST API. for an example I have created a List named TestList. Following is the field details:

Title: Text
TestColumn1: Text
TextColumn2: Text
TestColumn3: People and Group

Now to check the field details and check the details of the fields using the following REST API URL:


http://SITEURL/_vti_bin/client.svc/web/lists/getByTitle('TestList')/items

Now you will get following data in IE Or Chrome:

Find your column name from the XML page. Now check the above picture carefully, the userid needs to be saved in the TestColumn3Id column not in the TestColumn3. Now check the following code:

Go To SiteAssets and & Add jquery-1.11.1.min.js and TestScript.js. Add the following code in the Scripts.js file
Open any page & Insert content editor webpart. Include the below code in Content Editor.

//Code for content editor:

<table>

<tbody>

<tr>

<td>Title:</td>

<td>

</td>

</tr>

<tr>

<td>

</td>

</tr>

<tr>

<td>

</td>

</tr>

If you want to include any CSS files then include the below line

Code For TestScript.js:

Below is the Code for people picker (This will load on page load & Change the html div control to people picker):

$(document).ready(function () {

initializePeoplePicker('peoplePickerDiv');

});

//Auto Populate User and Group Field

function initializePeoplePicker(peoplePickerElementId) {

// Create a schema to store picker properties, and set the properties.

var schema = {};

schema['PrincipalAccountType'] = 'User,DL,SecGroup,SPGroup';

schema['SearchPrincipalSource'] = 15;

schema['ResolvePrincipalSource'] = 15;

schema['AllowMultipleValues'] = true;

schema['MaximumEntitySuggestions'] = 50;

schema['Width'] = '280px';

// Render and initialize the picker.

// Pass the ID of the DOM element that contains the picker, an array of initial

// PickerEntity objects to set the picker value, and a schema that defines

// picker properties.

this.SPClientPeoplePicker_InitStandaloneControlWrapper(peoplePickerElementId, null, schema);

}

//Below code will call the Button click event for ADD list item (first we are getting the user id from the selected people Picker & in the success event we are calling the update function):

function fnCreateItem()

{

getUserInfo();

}

// Render and initialize the client-side People Picker.

// Query the picker for user information.

function getUserInfo() {

// Get the people picker object from the page.

var peoplePicker = this.SPClientPeoplePicker.SPClientPeoplePickerDict.peoplePickerDiv_TopSpan;

// Get information about all users.

var users = peoplePicker.GetAllUserInfo();

// Get the first user's ID by using the login name.

getUserId(users[0].Key);

}

// Get the user ID.

function getUserId(loginName) {

var context = new SP.ClientContext.get_current();

this.user = context.get_web().ensureUser(loginName);

context.load(this.user);

context.executeQueryAsync(

Function.createDelegate(null, ensureUserSuccess),

Function.createDelegate(null, onFail)

);

}

function ensureUserSuccess() {

addListItem('https://<SiteURL>','TestList',this.user.get_id());

}

function onFail(sender, args) {

alert('Query failed. Error: ' + args.get_message());

}

//Code to Add new list item:

// Adding a list item with the metadata provided

function addListItem(url, listname,userid) {

alert('UserID: '+userid);

// Prepping our update

var item = $.extend({

"__metadata": { "type": "SP.Data.TestListListItem"}

}, {'Title': $('#txtTitle').val(),'TestColumn1': $('#txtTestColumn1').val(),'TestColumn2': $('#txtTestColumn2').val(),'TestColumn3Id': userid }); //If it is multi user field then instead of 'userid' we need to use -> {"results": [userid]} OR {"results": [userid1,userid2]}

// Executing our add

$.ajax({

url: url + "/_api/web/lists/getbytitle('" + listname + "')/items",

type: "POST",

contentType: "application/json;odata=verbose",

data: JSON.stringify(item),

headers: {

"Accept": "application/json;odata=verbose",

"X-RequestDigest": $("#__REQUESTDIGEST").val()

success: function (data) {

alert('New item added');

error: function (data) {

alert('FAILED');

}

});

}
