Check current user in sharepoint group

Question

I need to write a function where I need to check if current user belong to specific sharepoint group.

Senario: I have site like ship, logistic etc and sharepoint group like ship site member, logistic site member. User ABC is added in ship site member as he belong to ship.

When user login to site function need to validate if ABC belong to ship or logistic or both or more.

Please someone provide me piece of code

Answer 1

Here you go:

<script type="text/javascript" src="/_layouts/js/jquery-1.11.0.js"></script>
<script type="text/javascript" src="/_layouts/js/jquery.SPServices-2014.01.js"></script>

<script type="text/javascript">

$(document).ready(function(){

isGroupMember("Your User Group", function(result){
if(result){

//do something
}
});
});
function isGroupMember(groupName, callback)
{
$().SPServices({
    operation: "GetGroupCollectionFromUser",
    userLoginName: $().SPServices.SPGetCurrentUser(),
    async: true,
    completefunc: function(xData, Status) {

callback( !!($(xData.responseXML).find("Group[Name='" + groupName + "']").length) ); /* returns bool */
}
});
};

</script>

This should do what you need it to do. I hope :) Good Luck!

You can use the below C# code:

SPGroup group = site.Groups["GroupName"];

bool isUser = site.IsCurrentUserMemberOfGroup(group.ID);

if (isUser)
{
   //condition
}
