Add Salesforce Community Member Programmatically

Salesforce stores community members in NetworkMemberGroup object. Using apex we cannot insert the community member. So we can make a REST API call to add community member.

Sample Code:

//Get Endpoint URL
String endpointURL = URL.getSalesforceBaseUrl().toExternalForm()+'/services/data/v48.0/sobjects/NetworkMemberGroup';
HttpRequest req = new HttpRequest();  
req.setEndpoint(endpointURL);  
req.setMethod('POST');
req.setHeader('Authorization', 'Bearer ' + UserInfo.getSessionId()); 
req.setHeader('Content-Type', 'application/json;charset=UTF-8');
//Add Community Id as NetworkId and Profile Id as ParentId
req.setBody('{"NetworkId":"0DB1I000000TP59WAG","ParentId":"00e1I000001uXJUQA2"}');
Http http = new Http();
HttpResponse response = http.send(req);
System.debug('response-' + response);

Note: Add your salesforce base URL as remote site settings and then execute above code in developer console anonymous window.

How to use jQuery in Salesforce Lightning Aura Component?

Step 1: Upload the jQuery library as a static resource in your Org.

Step 2: Use ltng:require to load static resource JavaScript libraries on your component.

<aura:component>
    <ltng:require scripts="{!$Resource.YourStaticResourceName + '/jQueryFileName.js'}" />
</aura:component>

Step 3: To utilize the library include the afterScriptsLoaded event and add the method in your aura component JS controller.

Aura Component :

<aura:component>
    <ltng:require scripts="{!$Resource.YourStaticResourceName + '/jQueryFileName.js'}" afterScriptsLoaded="{!c.handleAfterScriptsLoaded}" />
</aura:component>

JS Controller:

({
    handleAfterScriptsLoaded : function(component, event, helper) {
        jQuery("document").ready(function(){
            console.log('jQuery Loaded');
        });
    }
})

Generic File Related List Lightning Component

Apex Class:

/*

@Description : Related Files Controller
*/
public class RelatedFilesController {
    
    @AuraEnabled
    public static List<ContentDocument> getRelatedDocs(Id recordId){
        List<ContentDocument> cdList = new List<ContentDocument>();
        List<ContentDocumentLink> cdlList = [SELECT ContentDocumentId FROM ContentDocumentLink
                                             WHERE LinkedEntityId = :recordId];
        Set<Id> cdIds = new Set<Id>();
        for (ContentDocumentLink cdl : cdlList) {
            cdIds.add(cdl.ContentDocumentId); 
        }        
        cdList = [SELECT Id, Title, FileType, OwnerId, Owner.Name, CreatedDate,
                  CreatedById, CreatedBy.Name, ContentSize
                  FROM ContentDocument WHERE Id IN :cdIds];
        return cdList;
    }
    
    @AuraEnabled
    public static string getDocURL(Id docId){
        ContentVersion cv = [SELECT Id FROM ContentVersion WHERE ContentDocumentId = :docId AND IsLatest = true];
        String cvDownloadURL = URL.getSalesforceBaseUrl().toExternalForm() + '/sfc/servlet.shepherd/version/download/' + cv.Id;
        return cvDownloadURL;
    }
    
    @AuraEnabled
    public static void deleteDoc(Id docId){
        ContentDocument conDoc = new ContentDocument(Id = docId);
        delete conDoc;
    }
}

Google reCAPTCHA on Visualforce Page

Step 1: Configure the Google reCAPTCHA and get the Site Key & Secret Key

  • Login to Google reCAPTCHA
  • Register a new site
  • Add Label e.g. Salesforce.com
  • Select reCAPTCHA type “reCAPTCHA v2”
  • Select “I’m not a robot” Checkbox option.
  • Add a domain e.g. yourorgurl.com
  • Accept the reCAPTCHA Terms of Service
  • Submit and get the Site Key & Secret Key

Step 2: Add Google as a Remote Site in Salesforce

Step 3: Create apex controller

/*

*/
public class GoogleReCAPTCHAController {
    
    public Boolean verified { get; private set; }

    }
    public String firstName{get;set;}
    public String lastName{get;set;}
    public String publicKey {get;set;}

                ret = hdrs.get('x-original-remote-addr');
            else if (hdrs.get('X-Salesforce-SIP')!= null)
                ret = hdrs.get('X-Salesforce-SIP');
            return ret;
        }
    }

    }
    
    public PageReference submit(){

        HttpResponse res = getGoogleReCAPTCHAResponse(baseUrl,'secret=' + secretKey + '&remoteip=' + remoteHost + '&response=' + response);

                    break;
                }
            }            
        }   
        if(this.verified){

            System.debug('ERROR Message-' + ex.getMessage());
        }
        return response;
    }
}

Step 4: Create VF Page

<apex:page controller="GoogleReCAPTCHAController" sidebar="false" showHeader="false" cache="false" id="pg">
    <script type='text/javascript' src='https://www.google.com/recaptcha/api.js'/>
