when using addScriptDeclaration, the script is added in the first tag that is found inside the HEAD tag.

Is it possible to add it just before </HEAD>?

You can do this by using the new feature Child Templates in Joomla 4.1. Step by step details:

  1. System > Site Templates > Cassiopeia Details and Files > and hit "Create Child Template"
  2. Open index.php under /templates/cassiopeia
  3. Select all the code and copy. Then close.
  4. Go to System > Site Templates > and click to the newly created child template
  5. Hit to "New File" and name it index.php
  6. Paste the code.
  7. Open templateDetails.xml and add the following code:
    <field name="myJS" type="textarea" label="My JS script" />
  8. Edit child template index.php file, and add this new line inside <head> </head> tags:
    <script><?php echo $this->params->get('myJS'); ?></script>
  9. Go to System > Site Template Styles and click on the child template
  10. On the Advanced tab you will see a new field My JS script.
    There you can add your custom JS code.

That's all !

Yes you can put in the head, but its most common to put it before the tag

  • The script must be in the template index.php, or you can use Sourcerer from Regular Labs Commented Sep 17, 2020 at 21:35
  • The system has flagged this post as being low-quality (because of its length/content). I think perhaps the OP is asking about how to ensure that the new declaration is appended to the <head></head> as the last child inside of it. In other words, the OP is trying to ensure that the declaration comes after all other declarations in the head tag. Please do not extend your answer's advice by adding comments. When you have additional relevant details to add, please edit your post so that the whole story is in one cohesive place (then delete your comment). Commented Sep 17, 2020 at 22:30

There is a "dirty" way to do this. Use regular labs rereplacer and simply replace in the head and replace

with something before it
