The append attribute

A handy Perch template feature is the append attribute. The template engine appends the value of the append attribute to the end of a field.

Perhaps it is most commonly used when you want to append an ellipsis to truncated text:

<perch:content id="desc" type="textarea" words="50" append="...">

You can also use it instead of littering your template with a bunch of perch:if tags. Instead of checking whether a field exists to append something like a comma ,:

<perch:content id="city" type="text"><perch:if exists="city">,</perch:if>

You can use the append attribute which is only applied if the field exists:

<perch:content id="city" type="text" append=",">
