The JWT expression parser is very powerful when it come to composing texts.
This page contains a comprehensive overview of all related information.
Fixed values
-
When used inside the function mode (
%{...}), texts need to be written in double quotes, e.g., "This is a text" -
Operator + is used for concatenating texts. e.g.,
"This is" + " a text." = "This is a text.". -
The Escape character is "
\" . This character can precede any of the following characters: ",\, n, r, t, f and b in order to invoke an alternative interpretation. e.g. \n for a linefeed.
If you want to introduce a double quote in a text expression you should precede it with escape character \ as in "The man said: \"Hello!\".", where we are using the escape character\to write the text Hello! in double quotes.
Variable values (field values)
Text field values can be inserted into expressions using field codes in the format %{...somefield}, or %{...somefield.i} for referencing concrete levels in cascading select fields (i = 0 for base level).
Pro tip
For checking if a field has a value you can use %{...somefield} = null or %{...somefield} != null.
For a concrete level in a Cascading Select or Multi-Cascading Select field, you should use %{...somefield.i} = null or %{...somefield.i} != null.
Any field type has a text value, so you can also use%{...somefield} to insert text values of fields of type Number (which includes Date and Date-Time values). Read more about Data types (JWT expressions).
