WYSIWYG-editor removes template partials/template variables

Question

I am using Wygwam as WYSIWYG-editor. Now when I add a template variable or template partial inside an html-tag in a field which uses Wygwam it will be removed when switching from source to visual.

That means I enter e.g. in the source-code something like

<a href="test1" {variable1}>test1</a>
<p>test{variable2}</p>

and after switching to Wysiwyg-layout the code changes to

<a href="test1">test1</a>
<p>test{variable2}</p>

Note that the variable outside the tag still is there (variable2), but the one inside the a-link is gone (variable1).

The "restrict allowed HTML"-setting is off, see image:

Possibly the CKEditor-setting "extraAllowedContent" could help me, but I am not sure and do not understand how I could change this setting.

Thanks for any help with this!

Answer 1

I think Wyvern (an other wysiwyg) can "process" the ee variables and partials. https://expressionengine.com/add-ons/wyvern

Answer 2

I don't think template variables are supposed to be rendered inside WYGWAM to begin with. I just ran a test and the variable name {tp_test} was retained literally from Source to Preview, and then in an actual web page, as well.

EDIT: You can use https://expressionengine.com/add-ons/allow-ee-code to allow template code in fields.

So chasing if/when WYGWAM erases it is kind of a red herring. But yes the extraAllowedContent would fix that. e.g., I have "i[*]" to allow everything inside <i> tags (FontAwesome).
