Variable to check for web view vs. email

[luke-nehemedia]

A client of mine often includes videos in their newsletters. Since this is not really possible in an email, I only include a cover-image of the video with a link to the web-view of the newsletter in place of the video. When the user clicks on the link it opens the web-view and the video is loaded in place of the cover-image.

To implement this, I have to check whether the current render is a web-view or the email-view. It would be very handy to have a variable in place like isWebRequest to check for this.

Right now I use the following code:

{% if craft.app.controller is instance of('craft\\controllers\\TemplatesController') %}
      <mjml...>display video</mjml>
{% elseif (craft.app.controller is instance of ('craft\\controllers\\QueueController')) or (craft.app.controller is instance of ('putyourlightson\\campaign\\controllers\\SendoutsController')) %}
    <mj-image href="{{browserVersionUrl}}" target="_blank" /> Link to web-version</mjml-image>
{% endif %}

This works for the sendout-preview and the sent mail, but not for test-mails. Therefore it would be really handy to have a variable or function to check for this.

Makes sense, will try to fit this in for the next release, thanks for the suggestion!

Looked into this and there are some other things that you should be able to check for to determine whether this is a web request or not, the simplest being whether the variables variable is defined.

{% if variables is defined %}
    This is a web request.
{% endif %}

I went ahead and added the isWebRequest variable in 175911f for the next release.
