How to edit {{custom_field.page_header_slug}}

Page Headers don't have a slug (you can't view them like a page or post), and it doesn't have any post content (it uses a custom field for the content).

The template tag can be used to display custom fields, which are added to the individual pages or posts that the Page Header is applied to.

Let me know if you need more info :)

Thank you, Tom. Maybe I'm being oblivious. I guess I'm still wondering where the h2 text "support your headline" and p text "a simple introduction to your offer" is stored. It appears to be custom fields that are being fed from somewhere.

Big head has:

<h1>{{post_title}}</h1>
<h2>{{custom_field.page_header_slug}}</h2>
<p>{{custom_field.page_header_body}}</p>
<a href="{{custom_field.page_header_url}}" class="button">{{custom_field.page_header_label}}</a>

where are these custom_fields located? Thanks buddy!

Ah, while you're editing each post or page, look for the "Custom Fields" metabox. If you don't see it, click the "Screen Options" link at the top right of the page, and make sure "Custom Fields" is checked.

Now you'll see the Custom Fields metabox, which should contain those values (if they're set for that page).

Let me know :)

OK mind blown. Never noticed that before! I've used ACF on my site, but have no idea this functionality was here. What's plugin is providing this or where is this coming from? I think that's my last question.

The Custom Fields metabox? It's a core WordPress feature :)

Wow. Definitely never knew the custom fields were there. Mind blown. Glad to have found the answer right at the source well over a year later :)
