SOLVED: (HREFLANG, Mulitlingual Support) -How to Decode HTML from custom field?

Hi folks,

I try to add some custom HTML in the header of a PAGE (so Tools -> custom HTML ist NOT working, because for whole site).

What I did:

• I added a custom post.config (textarea) like you can read here
• I customized head.hbs with code {{@config.post.addInHeader}} on the right place
• I added <link rel=”alternate” hreflang=”en” href=”https://www.example.com/en&#8221; /> in the field
• It works, but…

Problem:

HTML entities are encoded. I need to decode.

While I write, I found the solution, but I write it down here, because I saw more questions regadring HREFLANG, Multilingual, etc. This could be a solution for that!

You have to use 3 braces, not only 2:

{{{@config.post.addInHeader}}}

So, here is my solution for Multilingual Support:

1. Open theme -> config.json
2. Find “postConfig”-Section
3. Insert code at the end of the section:

   {
       "name": "addInHeader",
       "label": "Insert Tags in Post-Header",
       "value": "",
       "type": "textarea"        
   }
   

4. Open C:\Users\yourUserName\Documents\Publii\sites\mypagecom\input\themes\ (How to handle overrides)
5. Create folder {{theme}}-override
6. Copy sites\mypagecom\input\themes\<span style=”color: #ff0000;”>{{theme}}</span>\partials\header.hbs to sites\mypagecom\input\themes\<span style=”color: #339966;”>{{theme}}-override</span>\partials\header.hbs
7. Add {{{@config.post.addInHeader}}} directly before closing Head-Tag.
8. Save, Close and RESTART publii.
