getSalesforceBaseUrl() in a Custom Email Template

Question

I've created a Custom Email Template. In the HTML Email Content, a few fields are displayed and I've created a button with a link

<a href="https://c.cs15.visual.force.com/apex/PortalCasePage?id={!Case.Id}" class="btn-Open-Case">Open Case</a>

to direct the customer to the Portal Case Page. This is working in one environment. To make this work in the other environments where the URL changes, I'm trying to make use of the getSalesforceBaseUrl(). We have an URL helper class that returns the appropriate URL. But how do I merge that in this HTML link? Thanks in advance.

Answer 1

To get the string value of the base url use:

String fullFileURL = URL.getSalesforceBaseUrl().toExternalForm()

then append the '/' + your other parameters you may need

Assuming your URL helper class is not named URL

Also, you will probably need to change to a VF email template. Look for other answers though that may have a way to do it in the HTML template. (One clunky way is to populate a field on the case that holds the base URL and use a trigger to set the value. Then you could use that in the custom HTML email template. Or use a custom setting)

Answer 2

You can simply use, this will solve your problem.

href='{!Case.Link}' target='_blank' >{!Case.CaseNumber}

between anchor tag i.e. a

Answer 3

To get Base URL just simply use

{!MID(Account.Link, 1, LEN(Account.Link)-15)}

This will give you Base URL. Were Account.Link is standard field in Email Template for Account Object. Similarly you can get this Link fields for all objects in email Template.

If you want related record Link in Email Template then simply use

{!MID(Contact.Link, 1, LEN(Contact.Link)-15)}{!Contact.AccountId}
