Tutorial : E-mail Templates & Custom Placeholders

E-mail templates define the structure and content of marketing e-mails that you send to customers using an e-mail or dialog activity. 

E-mail templates can contain placeholders for content, such as e-Marketing Spots, links, unique promotion codes, and the customer's first and last name. When it is time to deliver the e-mail, the server replaces the placeholders with actual content.

While using the email templates , we may be faced with providing custom placeholders , as per the client requirements.

Below are the steps to do so. For demonstration purposes , we would be introducing the customer's phone number as a custom placeholder attribute.

1. Customize the Management Center Open-laszlo files to include the new custom tag for your new custom attribute.

 File
/LOBTools/WebContent/WEB-INF/src/lzx/commerce/marketing/restricted/widgets/EmailTemplateRichTextEditor.lzx

Step 1: Modify the  open lazlo file to introduce "Customer Phone Number" in the selection dropdown.

1. Locate the text "<mktTextlistitem value="lastName" displayName="${mktMarketingResources['lastName'].string}"/>"

2. Add the below text in the next line
<mktTextlistitem value="phoneNumber" displayName="Customer Phone Number"/>

The completed code will look as follows :

Step 2: Modify the  on-click handler to insert the custom tag <e-mail:PhoneNumber /> in the editor when the user selects "Customer Phone Number" and clicks on "Insert"


1. Locate the text "<handler name="onclick">"

2. Add the below text in the function implementation
  else if(selected == "phoneNumber") {
     classroot.insertTextAtSelection("<e-mail:PhoneNumber />");
   }

The completed code will look as follows :

Step 3: Build the Open Lazlo project - LOBTools

Right Click "LOBTools" project and click on "Build OpenLaszlo Project" as show in the figure below. Restart server.

.

This concludes the Management Center customizations.

  

2. Introduce a Tag implementation class

1. Create a tag implementation class which would contain the logic to replace the placeholder tag <e-mail:PhoneNumber /> with actual content.

This class should implement the "com.ibm.commerce.emarketing.emailtemplate.tag.Tag" interface. Follow the link to understand the interface methods which need to be implemented.

For the pupose of this tutorial , let the fully qualified name of this class be :

'com.wcshub.commerce.emarketing.emailtemplate.tag.TagPhoneNumber' 

2. Make an database entry in the table TAGCLASS.
To more about this table , follow the Infocenter link.  The sample query is provided below:

 insert into tagclass values ('PhoneNumber',  'com.wcshub.commerce.emarketing.emailtemplate.tag.TagPhoneNumber' ,  'Implementation class for Phone Number Tag' , NULL  );

The tutorial is now complete. Test the customizations.
