Meta Box

That is what we ended up doing. For anyone in the same boat, we ended up using a role of "Pending" that was a duplicate of the Subscriber role.

[mb_user_profile_register id="meta-box-id" role="pending"]

Then as part of the approval process, the admin changes the role to "Approved" which has the capabilities we want, then we use another plugin to fire off the account activation and all of that stuff.

Thanks for the help!

We were able to accomplish this another way, thank you for your help!

Okay, follow up question:

I have followed the examples you shared, and ended up with the resulting code:

//adapted from: https://support.metabox.io/topic/mb_user_profile_register-autocompletenew-password/
//relevant docs: https://docs.metabox.io/extensions/mb-user-profile/#form-fields-filters
function add_more_registration_fields( $fields ) {
        $fields = [
			'first_name' =>[
                'id'   => 'first_name', // THIS
                'name' => 'First Name',
                'type' => 'text',
				'required' => true,
				'columns' => 4,
            ],
   			'last_name' =>[
                'id'   => 'last_name', // THIS
                'name' => 'Last Name',
                'type' => 'text',
				'required' => true,
				'columns' => 4,
            ],
            'username'  => [
                'name'     => __( 'Username', 'mb-user-profile' ),
                'id'       => 'user_login',
                'type'     => 'text',
                'required' => true,
				'columns' => 4,
            ],
            'email'     => [
                'name'     => __( 'Email', 'mb-user-profile' ),
                'id'       => 'user_email',
                'type'     => 'email',
                'required' => true,
				'columns' => 6,
				'desc' => 'Used for notifications and alerts (if opted-in).',
            ],
			'phonenumber'  => [
            'name'     => __( 'Phone Number', 'mb-user-profile' ),
            'id'       => 'phonenumber',
            'type'     => 'tel',
			'required' => true,
			'desc' => 'Used for notifications and alerts (if opted-in).',
			'columns' => 6,
        	],
			'password'  => [
                'name'     => __( 'Password', 'mb-user-profile' ),
                'id'       => 'user_pass',
                'type'     => 'password',
                'required' => true,
				'columns' => 6,
                'desc'     => '<span id="password-strength" class="rwmb-password-strength"></span>',
                'attributes' => [
                    'autocomplete' => 'new-password'
                ]
            ],
            'password2' => [
                'name'     => __( 'Confirm Password', 'mb-user-profile' ),
                'id'       => 'user_pass2',
                'type'     => 'password',
                'required' => true,
				'columns' => 6,
            ],
            // ... add more fields here
        ];
        return $fields;
    }
add_filter( 'rwmb_profile_register_fields',  'add_more_registration_fields' );

Everything works except the first 2 fields. The first and last name do not get copied into the user meta. I am following the instructions listed here: https://docs.metabox.io/extensions/mb-user-profile/#edit-default-fields. The IDs match. Is there something else I'm doing wrong?

When I try to submit the contact form, I get this error:

The link you followed has expired.

Can you send me an email directly, [email protected] so that I can respond back with the credentials?

Can you please share some screenshots of the issue (full screen)?

Here are some screenshots of what I'm seeing when I look at the offer and listing:

offer
https://prnt.sc/Db5Vz3vrv5L3

listing
https://prnt.sc/Db5Vz3vrv5L3

And please notice that the custom field (relationship) shows on the object from get object type, post type, and field settings from object to. That means when you edit a listing post, you will see a meta box with a list of offer posts and some post statuses.

I'm not sure I'm understanding what you mean here - when I view either an offer or listing I can see a dropdown for the other related field.

Taking another look at the Custom Fields section in Gravity Forms for the Advanced Post Creation it's possible to add a new custom field in and use the 'text_07vqcymyr6iw' field name from Meta Box Custom Field Group solves my issue. But I'm still left mapping each field from the form over, is there an easier way to do this or am I stuck doing this for each field?
