Create header file in the child theme

Hi there,

You don't actually need a child theme to install GOogle Tag Manager.

Simply create a hook element using wp_head hook should do:

Let me know if this helps :)

Hi :)

Thank you for your reply, I also found the guide that explains it :) I have installed the child theme only to install Google Tag Manager so is it necessary that I leave the child theme activated or can I use the parent theme?

Thank you :)

Hi there,

if you have added the GTM to your Child Theme then you must keep it enabled.

Hi,

Thank you very much :) If I install the GTM in the parent theme, and I don't need any other changes, is it useful that I continue to use the child theme or can I disable it?

I'm sorry for the questions and thanks for your help :)

You should never edit the parent theme files.
If you want to add it without a child theme then following this article:

https://docs.generatepress.com/article/implement-google-tag-manager/

Ok, I have the last question: I previously added the GTM tag following that guide but with the child theme active. Following that guide, does the theme have to be parent or child?

Thank you for your help and I'm sorry because I'm not expert :)

If you used the Function method ie. this:

https://docs.generatepress.com/article/implement-google-tag-manager/#using-functions

Then those files are added to your Child Theme. And Yes you must keep the Child Theme Active.

Thank you :) And if I use the hook method do I have to keep the child theme active or is it not necessary? I installed the child theme only to add the GTM tag, in case that I don't need the child theme to use the hook method and I don't have to make other changes, would it be necessary to keep the child theme active?

Thank you! :)

And if I use the hook method do I have to keep the child theme active or is it not necessary?

No - you don't need a child theme in this case :)
