About Twig template variables
Twig template variables put data from your ezyVet site in a document template. You can use Twig template variables in templates for printed documents and PDF documents.
When you print a document, ezyVet replaces each Twig template variable with data from your ezyVet site. For example, a variable can show the name of the client or the total of an invoice.
With Twig code, a document can also show a text only when a condition is true. And a document can show the same text for each item in a list of records or values.
How to use Twig template variables
To use Twig template variables in a document template, select Use New Templating Engine in the settings of the template. For more information, refer to Configure a document template to use the Twig template system.
The template editor does not show the {% %} tags of Twig. To see or change these tags, select the horizontal ellipsis ( ⋯ ), then select Source code.
A Twig template shows data from the record that you print it from. If you print the template from a different type of record, some variables can show no value. For a clinical document that you print from different types of records, a template that uses the classic template system can be better.
