{% capture CFH %}{{ content_for_header  }}{% endcapture %}{{ CFH }}

{% if CFH contains 'admin_bar_iframe' %}
  {% assign isAdmin = true %}
{% endif %}

Thanks for the gist! Just thought I'd mention {% capture CFH }} should be {% capture CFH %}.

Also, is it necessary to have {{ CFH }} at the end of line 8?

Finally got round to updating the typo mentioned above.
Slow, be I got there in the end...

Really useful, thanks for this!

doesnt works anymore

Change 'admin_bar_iframe' to 'adminBarInjector'

I just used preview_bar_injector and it's working correctly for me.

  if CFH contains 'adminBar' or CFH contains 'previewBar'
    assign isAdmin = true
  endif

shopify uses:
adminBarInjector when you are viewing the live theme
previewBarInjector when you are previewing a non-live theme

this whole snippet will trigger a Shopify theme-check linter ContentForHeaderModification error but I'm choosing to ignore it
