Composite

The composite field type combines one or more text values into a single field. This can be useful for creating a value to sort the region by, or for outputting commonly combined fields as a single unit.

It has no form input of its own – it takes values from other text fields.

<perch:content id="firstname" type="text" label="First name" />
<perch:content id="lastname" type="text" label="Last name" />
<perch:content id="fullname" type="composite" for="firstname lastname" />

In the above example, if the first name was “Oscar” and the last name “Wilde”, then the fullname composite field would contain the value “Oscar Wilde”.

Joining fields

By default, the fields are joined with a single space. You can specify a different joining character with the join attribute.

<perch:content id="firstname" type="text" label="First name" />
<perch:content id="lastname" type="text" label="Last name" />
<perch:content id="fullname" type="composite" for="lastname firstname" join=", " />

This time, the composite field would contain “Wilde, Oscar”. This might be useful for sorting a region by last name, first name.
