What is the correct syntax to test if a file has been uploaded in a webform in a twig email template?

For a text area, {% if webform_token('[webform_submission:values:question_text_area:value]', webform_submission) %} works fine but to test if a file has been uploaded, {% if webform_token('[webform_submission:values:join_a_file:value]', webform_submission) %} does not work.

Also, when there's a file uploaded, I want to display in the email only the title of the file ... {{ webform_token('[webform_submission:values:join_a_file:delta:format:value]', webform_submission) }} works but it outputs a link to that file. Is it possible to just have the text of the file name?

Thanks!

That is a great question.

Getting just the filename is not currently supported but you can pull the file's URL using [webform_submission:values:join_a_file:delta:format:url]

The current list of supported formats for uploaded files is here. I created a ticket to add machine name to element submission display formats so that this information is exposed to site builder.

If you need just the file name, please create a new ticket in the Webform module's issue queue.

  • Thank you for creating the ticket ... I was going to wait to see if I could extract the filename from the url but even when I put [webform_submission:values:join_a_file:delta:format:url] in my email twig template, the output is always a link with the filename. I should have specified my field is a Document File ... maybe it doesn't work with this filetype?

  • Also, I tried creating a conditionnal email that would be enabled only if my file field was empty to solve my problem of testing if a file has been uploaded in a twig email template ... is "Empty" the correct Trigger/Value for that use case? I tried it but the email is not sent when the condition is met.

  • The [webform_submission:values:join_a_file:delta:forma:name] token is now supported in the latest dev release. If you are finding other bugs please create a ticket in the Webform module's issue queue. drupal.org/project/issues/webform?version=8.x
