If I am creating a confiform field definition and selecting the definition type as 'autolink'
Basically I want to create a link with a prefix value and a dynamically added value to a field within the entry.
How do I achieve this concat ability?
do not bother too much with the autolink field definition type. If it is any other field definition type that I can use and present the resultant as a link on the entry. That should be fine.
To understand with an example:
Let us say, an entry in the form is: Facebook username: usernameXYZ
then it should create a link:
www.facebook.com/usernameXYZ
at least create the above link as the field value. If possible have a label for it: Facebook Profile(hyperlink or anchor tag).
