Conditional execution

Post functions are provided with an option to control their execution. You need to input a Nunjucks template in the Condition field, and based on the result of that expression, the post-function will either be executed or skipped.

To add a condition to control the execution of the post-function :

Select the check box Run this post-function only if a condition is verified.
Type a Nunjucks template that returns either true or false.

Note that any non-empty string that is not false will be considered as true and will thus let the post-function run.

For information on how to insert Nunjucks annotations see, How to insert information using Nunjucks annotations.
