Populate email body on custom CKEDITOR email editor in Salesforce.com

Other than using out-of-the-box Salesforce email editor , there are some scenarios where you need to build your custom email editor. You can build a custom email editor using CKEDITOR HTML editor.

Once you build the custom editor , you will face the issue while fetching the body of the template.

To display the email body in a HTML format from the predefined email templates , you can send the email using apex and then rollback immediately and fetch the email body in correct HTML format. 

Here is the sample code :-

Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();

String toAddress = 'testemaildomain@test.com';

String templateId = '<Fetch Id of email template>'

// Set the template id for which we need the HTML formatted body.

email.setTemplateId(templateId);

email.setWhatId(<Object Id>);

email.setSaveAsActivity(false);

email.setTargetObjectId(contactId);

email.setToAddresses(new String[] {toAddress });

if(!Test.isRunningTest()){

    Savepoint savept = Database.setSavepoint();

    Messaging.sendEmail(new Messaging.SingleEmailMessage[] {email});

    Database.rollback(savept);

} 

// Use the email instance to fetch the body                   

EmailTemplate emailTemlt = [Select id , body , TemplateType from EmailTemplate where id=: templateId];

String htmlEmailBody ='';                         

if(emailTemlt.TemplateType=='html' || emailTemlt.TemplateType=='visualforce' || emailTemlt.TemplateType=='Custom' ) {

    htmlEmailBody = email.getHTMLBody();

}else if(templateObj.TemplateType=='Text') {

    htmlEmailBody = email.getPlainTextBody();  

}
