Tell us what you are trying to do?

I have a custom post called "labs".

Every "lab" has only two text fields. Name and Email

Lets imagine I have a lab called Lab01 with email "example@example.com"

So I want to add a select box with that info to be able to select from wp-users like this (see example)

At the end, from normal wp-users (wp-admin/users.php) Will be able to select what lab we want to select

Is there any documentation that you are following?
I think I found similar ticket but is not what I am looking for :https://toolset.com/forums/topic/i-want-to-create-a-nationality-list-as-a-user-field-via-the-types-plugin/

Hi Rafael

I'm not quite sure I follow.

You want a select custom user field, and you want the options for that select dropdown to be automatically populated by posts of a custom type, is that right?

[rafaelL-2]

Totally right. Let me give a one more example. Just to be sure

My custom post, called "LAB" has currently two post:

Name: LAB01, email: example01@example.com
Name: LAB02, email: example02@example.com

So, from wp-admin/users.php, the select field will be populated from the current post type LAB, more specifically from the name field as you see on the image

Hi Rafael

You can use the wpt_field_options filter to dynamically fill a select field's options.

It is not documented (on our to-do list), so I put together some sample code which populates a field called "Choices" with the posts of the custom type "thing", which you should be able to adapt to your needs:

/**
 * Auto-populate custom User Field
 */
add_filter( 'wpt_field_options', 'tssupp_populate_user_field', 10, 2 );

function tssupp_populate_user_field( $current_options, $title_of_field ){

	if ( 'Choices' == $title_of_field ) {

		$current_options = array();

		$args = array(
			'post_type'		=>	'thing',
			'numberposts'	=>	-1
		);
		$posts = get_posts( $args );

		foreach ($posts as $key => $post) {

			$current_options[] = array(
				'#title'	=>	$post->post_title,
				'#value'	=>	$post->ID
			);
		}
	}

	return $current_options;
}

Hi again, thanks for your solution. However seems doesn't work

I did the following:

1-I create a select field called "labasociadoemail"

2- then I change on your code 'choices' by 'labasociadoemail' and 'thing' to my custom post type 'laboratorio' (as you can see at the bottom of the image.

You can see the result on the image. I understand your code. However I don't get why you do this IF:

  if ( 'Choices' == $title_of_field ) { 

I tried to remove the IF but still doesn't work.

Seems I deactivate the snippet by a failure, so I am happy to say It's working
