Display custom code only on pages with a specific tag

[annaisdevk]

For the option:

Tools & Plugins / Custom HTML / After every post

Is it possible to only display that code on specific pages? For example, all pages with a certain tag?

@annaisdevk - it is not possible via UI - you must use custom code in the theme to achieve that

@dziudek How could this be achieved with helpers?

I'm guessing you'd have to edit post.hbs, and add an #checkIf like this?

   {{#checkIf tags.id '==' 10}}
         your code here...
   {{/checkIf}}

Where "10" is the tag's ID, or could also be represented by a string of tag IDs such as "1,2,3"

[dziudek]

@candidexmedia - you can use ID, slug or any other field of post/tag/author from basic items https://getpublii.com/dev/post-tags/ to detect specific post.

In your code you have used non-strict equal so there is no diff if ID is 10 or "10" - in both cases it should work, but not for tags.id because such field does not exists - tags is array of tag elements: https://getpublii.com/dev/tag-tags/

So, if a user is aiming to have certain lines of code in a post, but only in posts that are tagged with Tag ID # 10, is this the correct form to use in post.hbs? :

   {{#checkIf tag.id '==' 10}}
         your code here...
   {{/checkIf}}

[dziudek]

@candidexmedia - It will be something like:

{{#each tags}}
  {{#checkIf this.id '==' 10}}
    custom code
  {{/checkIf}}
{{/each}}

@dziudek gotcha, thank you!!
