AEM form email template - Read repeatable fields

Avatar

Level 2

Hi,

 

We are working on a form where we have a panel with 5 fields repeated 10 times. These fields are text fields and user is supposed to enter values. Now we want to read user entered values of these fields and send in email.

We can read the value in Javascript using guideBridge as follows => guideBridge.resolveNode('parentPanel').instanceManager.instances[2].field1.value;.

But we are not able to read this value in email template. Any pointers will help here.

Sample form screen shot: -

As you can see the rows are repeated 10 times using repeatable settings.

I have created a custom workflow process step. In this step you pass the repeatable panel name,field in the repeatable panel, and the metadata property you want to store the value in

The form has this repeatable panel

workflowuser_1-1643410484851.png

When you submit this form the following metadata property gets created with the values entered in the form

workflowuser_2-1643410625277.png

 

You can then use the "guests" metadata property in your email template

Let me know if you need the code for the workflow process step

It would need some custom code

how would you want the repeatable values to show up in the email?

We want to capture all the fields entered by user in a table in email. I was hoping to find if there is an out of the box way to capture this (similar to text field  =>${textFieldName})

Thank you for your response. 

IF we have to write custom code, I was thinking to capture it using clientlib (by using guideBridge instancemanager) and then call rest api. It will work for us because we also have an api to send email.

 

Please do share your code for reference.

 

Thank you

the folowing is the code(no way production ready), but should allows you to test the functionality.

This code will be associated with the process step in your workfow.
