Creating a Sharepoint ‘Like’ through SOAP Requests

Sharepoint is not my most favorite environment to program in but I figure I’d share a cool javascript app I put together that communicates with Sharepoint’s SOAP API to add on to custom ‘like’ buttons (just like facebook!) With this feature, users can ‘like’ sharepoint items without going through the crazy sharepoint interface. This javascript can be added to a web interface, and users can ‘like’ items from there!

None of this garbage

I wrote some javascript/jquery code that can easily retrieve the number of ‘likes’ for a sharepoint list item or list. The script basically queries Sharepoint’s built in social services for the tag count with SOAP POST calls.

Get Like Count

Here is the script to get ‘like’ count:


<script>

function GetLikeCountFromService(strURL) {

var count = 0;

//change the webMethod var to match up to the correct sharepoint _vti_bin location. (https://msdn.microsoft.com/en-us/library/office/Bb862916(v=office.12).aspx)

var webMethod = \'/_vti_bin/SocialDataService.asmx?op=GetTagTermsOnUrl\';

var soapEnv = "<soap:Envelope xmlns:xsi=\'http://www.w3.org/2001/XMLSchema-instance\' xmlns:xsd=\'http://www.w3.org/2001/XMLSchema\' xmlns:soap=\'http://schemas.xmlsoap.org/soap/envelope/\'> <soap:Body><GetTagTermsOnUrl xmlns=\'http://microsoft.com/webservices/SharePointPortalServer/SocialDataService\'> <url>" + strURL + "</url> <maximumItemsToReturn>1</maximumItemsToReturn> </GetTagTermsOnUrl> </soap:Body> </soap:Envelope>";



$.ajax({

type: "POST",

async: true,

url: webMethod,

data: soapEnv,

contentType: "text/xml; charset=utf-8",

dataType: "xml",

success: function(data, textStatus, XMLHttpRequest) {

count  = $(\'SocialTermDetail\', data).find(\'Count\').text();

}

});

return count;

}

</script>

Called by: GetLikeCountFromService(‘<LIST OR LIST ITEM URL>’)

Example: GetLikeCountFromService(‘http://mysharepoint/list/item’)

Here is the script to post ‘likes’ to an article. Once again it’s a nice javascript that can put into an HTML header or what not.

Emulate a ‘like’

Script to post a ‘like’:


function AddLikeCountFromService(strURL) {

//change the webMethod var to match up to the correct sharepoint _vti_bin location. (https://msdn.microsoft.com/en-us/library/office/Bb862916(v=office.12).aspx)

var webMethod = \'/_vti_bin/SocialDataService.asmx?op=GetAllTagTermsForUrlFolder\';

var soapEnv = "<soap:Envelope xmlns:xsi=\'http://www.w3.org/2001/XMLSchema-instance\' xmlns:xsd=\'http://www.w3.org/2001/XMLSchema\' xmlns:soap=\'http://schemas.xmlsoap.org/soap/envelope/\'><soap:Body><GetAllTagTermsForUrlFolder xmlns=\'http://microsoft.com/webservices/SharePointPortalServer/SocialDataService\'><urlFolder>"+strURL+"</urlFolder><maximumItemsToReturn>1</maximumItemsToReturn></GetAllTagTermsForUrlFolder></soap:Body></soap:Envelope>";

$.ajax({

type: "POST",

async: true,

url: webMethod,

data: soapEnv,

contentType: "text/xml; charset=utf-8",

dataType: "xml",

success: function(data, textStatus, XMLHttpRequest) {

var info  = ($(\'SocialTermDetail\', data).text()).split(" ");

var guid = (info[0]).substring(0, info[0].length - 1);

//change the webMethod var to match up to the correct sharepoint _vti_bin location. (https://msdn.microsoft.com/en-us/library/office/Bb862916(v=office.12).aspx)

webMethod = \'/_vti_bin/SocialDataService.asmx?op=AddTag\';

//In the soapEnv request, you can change the title field to anything. This is the title of the thing the user is liking.

soapEnv = "<soap:Envelope xmlns:xsi=\'http://www.w3.org/2001/XMLSchema-instance\' xmlns:xsd=\'http://www.w3.org/2001/XMLSchema\' xmlns:soap=\'http://schemas.xmlsoap.org/soap/envelope/\'> <soap:Body><AddTag xmlns=\'http://microsoft.com/webservices/SharePointPortalServer/SocialDataService\'><url>"+strURL+"</url><termID>"+guid+"</termID><title>I like it!</title><isPrivate>false</isPrivate></AddTag></soap:Body> </soap:Envelope>";

$.ajax({

type: "POST",

async: true,

url: webMethod,

data: soapEnv,

contentType: "text/xml; charset=utf-8",

dataType: "xml",

success: function(data, textStatus, XMLHttpRequest) {

}

});

}
