Send Email using Apex and vf page by using email templates.

Hi friends,

Previously in this post I showed you how we can send emails using Messaging class, but many times we need to send email using email templates in apex code.

So in this post I am using email templates to an send email from apex code:

I am using 2 vf pages and 2 controller in this example:-

• SendEmailByTemplateVFPage - This is the page from where we are sending Email from template.
• ClsSendEmailByTemplate - This is controller class of "SendEmailByTemplateVFPage".
•  SelectTemplate - This is another vf page which is calling from "SendEmailByTemplateVFPage", in this page we are querying all the Email Templates.
• ClsSelectTemplate - This is controller class of "SelectTemplate".

Here the code:-

	public with sharing class clsSelectTemplate
	{
	private Map<Id, Folder> folderMap{get;set;}
	//List of string to store Alphabets character for Alphabetically searching
	public List<EmailingTemplate> emailingTemplates {get; set;}
	//This is map to fetch all ids of email folders.
	private Set<Id> folderListIds = new Set<Id>();
	//List of all folders's ids
	private Set<Id> folderOtherIds = new Set<Id>();
	//To get Template's value
	public String folderId {get; set;}
	//constructor
	public clsSelectTemplate()
	{
	emailingTemplates = new List<EmailingTemplate>();
	folderMap = new Map<Id, Folder>( [Select id , Name from Folder where Type = 'Email']);
	this.ETData();
	}
	public void ETData() //Method to get Name TemplateType Description FolderId from EmailTemplate
	{
	for(EmailTemplate e : [select Name, TemplateType, Description, FolderId from EmailTemplate where IsActive=true Order by Name])
	{
	if(!folderListIds.contains(e.FolderId))
	folderListIds.add(e.FolderId);
	EmailingTemplate tempE = new EmailingTemplate();
	tempE.templateId = e.Id;
	tempE.Name = e.Name;
	tempE.isSelected = false;
	tempE.TemplateType = e.TemplateType;
	tempE.Description = e.Description;
	emailingTemplates.add(tempE);
	}
	for(Folder f : folderMap.values())
	if(!folderListIds.contains(f.id))
	folderListIds.add(f.Id);
	}
	public void createTempList() //Method to get all folder and email template in eamil setting
	{
	emailingTemplates = new List<EmailingTemplate>();
	List<EmailTemplate> etList = new List<EmailTemplate>();
	if('All' == folderId)
	etList = [select Name, TemplateType, Description, FolderId from EmailTemplate where FolderId IN :folderListIds AND IsActive=true Order by Name];
	else if('Others' == folderId)
	etList = [select Name, TemplateType, Description, FolderId from EmailTemplate where FolderId IN :folderOtherIds AND IsActive=true Order by Name];
	else
	etList = [select Name, TemplateType, Description, FolderId from EmailTemplate where FolderId = :folderId AND IsActive=true Order by Name];
	for(EmailTemplate e : etList)
	{
	EmailingTemplate tempE = new EmailingTemplate();
	tempE.templateId = e.Id;
	tempE.Name = e.Name;
	tempE.isSelected = false;
	tempE.TemplateType = e.TemplateType;
	tempE.Description = e.Description;
	emailingTemplates.add(tempE);
	}
	}
	public List<SelectOption> getItems() // show email template according to selaeted email template folder
	{
	List<SelectOption> options = new List<SelectOption>();
	folderOtherIds = new Set<Id>();
	options.add(new SelectOption('All', 'All'));
	for(String f : folderListIds)
	{
	if(folderMap.get(f) == null)
	{
	folderOtherIds.add(f);
	system.debug('----------------folderOtherIds-------------'+folderOtherIds);
	}
	else
	options.add(new SelectOption(folderMap.get(f).id, folderMap.get(f).Name));
	}
	if(folderMap.size() > 0)
	options.add(new SelectOption('Others', 'Others'));
	return options;
	}
	class EmailingTemplate // inner class to get emailTemplates Properties
	{
	public Boolean isSelected {get; set;}
	public String templateId {get; set;}
	public String Name {get; set;}
	public String TemplateType {get; set;}
	public String Description {get; set;}
	}
	}
