Meta Box

Update:
Hi Peter,

With the following code, I have got the avatar and photo to show within the metabox group on elementor. The first value correctly populates the name and avatar.

//For display_name
add_shortcode("former_team_member_get_name", function (){
	global $post;
$ftm_post_type = get_post_type($post->ID); 
if(is_singular() && "team" == $ftm_post_type)
{
$group_id = rwmb_meta( 'archived_team_users_group','',$post->ID); 
foreach ($group_id as $x){
$f_user_id = $group_id['former_team_member'] ?? '';
foreach ($f_user_id as $user){
	$ff_user = get_usermeta($user);
}
		return sprintf($ff_user[1]);
		}}});

//For the avatar
add_shortcode("former_team_member_get_avatar", function (){
	global $post;
$ftm_post_type = get_post_type($post->ID); 
if(is_singular() && "team" == $ftm_post_type)
{
$group_id = rwmb_meta( 'archived_team_users_group','',$post->ID); 
foreach ($group_id as $x){
$f_user_id = $group_id['former_team_member'] ?? '';
foreach ($f_user_id as $user){
$profile_pic = get_avatar_url($user);
$main_html_markup = "<img src='$profile_pic'>";
}}
return $main_html_markup;	

		}});

However, when I try to use the metabox group field within a template that has values, it shows as blank.

How do I populate the metabox group correctly with shortcodes that then loop to show all the post values on a template?

Hi Peter,

Yes of course:

       $prefix = '';

'name'   => __( 'Archived Users', 'your-text-domain' ),
                'id'     => $prefix . 'archived_team_users_group',
                'type'   => 'group',
                'fields' => [
                    [
                        'name'            => __( 'Former team members', 'your-text-domain' ),
                        'id'              => $prefix . 'former_team_member',
                        'type'            => 'user',
                        'field_type'      => 'checkbox_list',
                        'select_all_none' => true,
                        'query_args'      => [
                            'role' => 'archive_team',
                        ],
                    ],

Hi Peter,

I am just trying to query a term from a post. And so dependent on if a taxonomy term was selected to do X
So I guess its your last snippet - thank you!

You can delete this. It was not the shortcode..

Oh I think I worked it out - the above was my first attempt using the label, not the value - and I think that is what was wrong!

$checked_box = rwmb_get_value('hidden_published_already', '', $post->ID );
if (( $new_status == 'publish') && ($old_status != 'publish') && (get_post_type( $post ) == 'research') && (($checked_box == 'Not published') || ($checked_box == 0))){ ..}// 0 is the value of unpublished

This is what I have. It either works, or it doesn't work. It doesn't work if I use === 0, but it does work if I use ==0. The issue is, using == 0 also means it fires when the value is 1

Thanks Long, that clarifies.

But if I use the post field, how do I update the relationship field too? I use the relationship to query both ways on other parts of the site, so important this is also updated

Ok Long, thank you for the clarification.

And my second question - how do you add custom fields to if statements?

Can I do it like:

$co_author_email = rwmb_meta( 'academicadd_co_author', '', $post->ID )

If ($co_author_email == 'y')

This is for something else, and the code works perfectly if no custom field conditions in the if statement, but then adding custom field conditions into if statements stops it from executing, even though the value is definitely there
