Visualforce email templates can leverage custom controllers to render highly customized content. To do so, include a custom component in a Visualforce email template that uses that custom controller.
public class findSmithAccounts { private final List<Account> accounts; public findSmithAccounts() { accounts = [select Name from Account where Name LIKE 'Smith_%']; } public List<Account> getSmithAccounts() { return accounts; } }
<apex:component controller="findSmithAccounts" access="global"> <apex:dataTable value="{!SmithAccounts}" var="s_account"> <apex:column> <apex:facet name="header">Account Name</apex:facet> {!s_account.Name} </apex:column> </apex:dataTable> </apex:component>
<messaging:emailTemplate subject="Embedding Apex Code" recipientType="Contact" relatedToType="Opportunity"> <messaging:htmlEmailBody> <p>As you requested, here's a list of all our Smith accounts:</p> <c:smithAccounts/> <p>Hope this helps with the {!relatedToType}.</p> </messaging:htmlEmailBody> </messaging:emailTemplate>
Notice that although the relatedToType attribute is required by the emailTemplate component, it does not have any effect on this example. It has the value of "Opportunity" only to show that it can take an object value that is different than the object used in the custom component.
