It was easy to link entries to Posts if these posts were created using Gravity Forms' Post fields, by checking these options on the field modal:

However, if the Posts were created using the Advanced Post Creation add-on, this option is not present. Therefore, I end up incorrectly suggesting this workaround to a user:

The problem with that is that the APC add-on does not store the {post_id} merge tag because it works with feeds, so you can have as many posts tied to a single entry as possible. More about the {post_id}

For that reason, it stores each created post ID as a separate entry meta, rather than a single post_id field.

To help with this, @bennemann created a custom shortcode that retrieves the latest post ID created by APC for a given entry:

function gk_apc_post_id( $atts ) {
	$entry_id = absint( $atts['entry_id'] ?? 0 );
	if ( ! $entry_id ) return '';

	$posts = gform_get_meta( $entry_id, 'gravityformsadvancedpostcreation_post_id' );

	return ! empty( $posts ) ? intval( end( $posts )['post_id'] ) : '';
}
add_shortcode( 'gk_apc_post_id', 'gk_apc_post_id' );

Usage: <a href="https://www.example.com/?p=[gk_apc_post_id entry_id={entry_id}]">View Post</a>

What's needed

• We need to create a custom Merge Tag built into GravityView for this that supports the possibility of one entry having more than one post associated with it.

Steps to reproduce

1. Create a form with regular fields (Single Input Text, Paragraph, etc). Don't use Post Fields;
2. Configure a post creation feed with the Advanced Post Creation add-on;
3. Submit the form;
4. Check if a Post has been created;
5. Create a View for this form;
6. When adding fields to the View, how would you link to that recently created post?
