Pass $cmb->object_id to function in select options

OK got it.

Call the function like so:

'options'  => 'example_get_array',

And get the ID like so:

function example_get_array($cmb){

$id = $cmb->object_id;
...
}

Good to hear you got this worked out ??

Hi there,

I’m trying to do a very similar thing but can’t quite get it to work!

I would like to dynamically populate a cmb2 select field with an array created from a repeatable group. The group has multiple fields, but I would only like to use the fields with the ID ‘name’.

I was trying something like this for the select field:

$cmb_user->add_field( array(
		'name'             => __( 'Select Contact', 'cmb2' ),
		'desc'             => __( 'Choose the default Contact person', 'cmb2' ),
		'id'               => $prefix . 'select_contact',
		'type'             => 'select',
		'show_option_none' => true,
		'options'  => 'contacts_get_array',
	) );

But can’t quite get my head around the function I would have to set up to get the name array out of the group array:

function contacts_get_array($cmb){

	$contacts = get_post_meta( get_the_ID(), '_dbem_user_contacts', true );

	foreach ( (array) $contacts as $key => $contact ) {
		$name = $position = $subject = $phone = $email = '';
	    $school_contact = esc_html( $contact['name'] );
	}
}

Any advice?

something like your $school_contact variable would need to be treated as an array and then returned in your contacts_get_array() function

something like

$school_contact[] = esc_html( $contact['name'] );

and then after the foreach is done simply

return $school_contact;

If things still aren’t quite right, I’d check on the necessary setup which may be a proper key => value setup for the array, instead of just an indexed array. I can’t recall at the exact moment.

the setup for the select field looks like this, according to the field types:

$cmb->add_field( array(
    'name'             => 'Test Select',
    'desc'             => 'Select an option',
    'id'               => '_wiki_test_select',
    'type'             => 'select',
    'show_option_none' => true,
    'default'          => 'custom',
    'options'          => array(
        'standard' => __( 'Option One', 'cmb' ),
        'custom'   => __( 'Option Two', 'cmb' ),
        'none'     => __( 'Option Three', 'cmb' ),
    ),
) );

Just can’t quite work out how to combine the two!

Is this what you are after:

function contacts_get_array($cmb){

	$contacts = get_post_meta( $cmb->object_id, '_dbem_user_contacts', true );
        $school_contact = array();
	foreach ( (array) $contacts as $key => $contact ) {
            //populate array with name of contact
	    $school_contact[] = esc_html( $contact['name'] );
	}
       return $school_contact;
}

and call it

$cmb->add_field( array(
    'name'             => 'Test Select',
    'desc'             => 'Select an option',
    'id'               => '_wiki_test_select',
    'type'             => 'select',
    'show_option_none' => true,
    'default'          => 'custom',
    'options'          => 'contacts_get_array',
) );

Hopefully Glinch helped with your issue Kaimee, let us know ??

Still no dice, can’t quite work out if it’s the function array, or how the select receives the options!

Using Glinch’s advice I revised both, however unfortunately I’m now getting a select field with 2 empty options, as per screenshot: https://postimg.org/image/x11q6ff27/

Note that the array is currently getting the data for 2 different contacts, so those 2 empty options could either be the function not getting their names meta data, or not formatted correctly for the select option to display them.

What code are you using? Will be easier to figure out where its going wrong.

If you are using the code I sent over it would suggest that there is nothing in the array you are passing to the select option.

This is the repeatable contacts group:

add_action( 'cmb2_init', 'asi_repeatable_contacts_user_profile_metabox' );
/**
 * Hook in and add a metabox to demonstrate repeatable grouped fields
 */
function asi_repeatable_contacts_user_profile_metabox() {
	// Start with an underscore to hide fields from custom fields list
	$prefix = 'dbem_user_';
	/**
	 * Repeatable Field Groups
	 */
	$cmb_group = new_cmb2_box( array(
		'id'           => $prefix . 'teachers',
		'title'        => __( 'Teacher Contacts', 'cmb2' ),
		'object_types'     => array( 'user' ), // Tells CMB2 to use user_meta vs post_meta
		'show_names'       => true,
		'new_user_section' => 'add-new-user', // where form will show on new user page. 'add-existing-user' is only other valid option.
	) );
	$cmb_group->add_field( array(
	    'name' => 'Teacher Contacts',
	    //'desc' => 'This is a title description',
	    'type' => 'title',
	    'id'   => 'teacher_contacts_title'
	) );
	// $group_field_id is the field id string, so in this case: $prefix . 'demo'
	$group_field_id = $cmb_group->add_field( array(
		'id'          => $prefix . 'contacts',
		'type'        => 'group',
		'title'        => __( 'Teacher Contacts', 'cmb2' ),
		'description' => __( 'Please add and update Teacher or Individual details here', 'cmb2' ),
		'options'     => array(
			'group_title'   => __( 'Contact {#}', 'cmb2' ), // {#} gets replaced by row number
			'add_button'    => __( 'Add Another Contact', 'cmb2' ),
			'remove_button' => __( 'Remove Contact', 'cmb2' ),
			'sortable'      => false, // beta
		),
	) );
	/**
	 * Group fields works the same, except ids only need
	 * to be unique to the group. Prefix is not needed.
	 *
	 * The parent field's id needs to be passed as the first argument.
	 */
	$cmb_group->add_group_field( $group_field_id, array(
		'name'       => __( 'Full name', 'cmb2' ),
		'id'         => 'name',
		'type'       => 'text',
		// 'repeatable' => true, // Repeatable fields are supported w/in repeatable groups (for most types),
	    'attributes' => array(
	        //'placeholder' => 'A small amount of text',
	        //'rows'        => 3,
	        'required'    => 'required',
	    ),
	) );
	$cmb_group->add_group_field( $group_field_id, array(
		'name'        => __( 'Position', 'cmb2' ),
		'id'          => 'position',
		'type'        => 'text',
	) );
	// $cmb_group->add_group_field( $group_field_id, array(
	// 	'name'        => __( 'Subject area', 'cmb2' ),
	// 	'id'          => 'subject',
	// 	'type'        => 'text',
	// ) );
	$cmb_group->add_group_field( $group_field_id, array(
		'name'             => __( 'Subject area test', 'cmb2' ),
		//'desc'           => __( 'field description (optional)', 'cmb2' ),
		'id'               => 'subject',
		'type'             => 'select',
		'show_option_none' => true,
		'options'          => array(
			'physics' 	   => __( 'Physics', 'cmb2' ),
			'chemistry'    => __( 'Chemistry', 'cmb2' ),
			'biology'      => __( 'Biology', 'cmb2' ),
			'admin'        => __( 'Administrator', 'cmb2' ),
			'other'        => __( 'Other', 'cmb2' ),
		),
	) );
	$cmb_group->add_group_field( $group_field_id, array(
		'name' => __( 'Phone', 'cmb2' ),
		'id'   => 'phone',
		'type' => 'text',
	) );
	$cmb_group->add_group_field( $group_field_id, array(
		'name' => __( 'Email', 'cmb2' ),
		'id'   => 'email',
		'type' => 'text_email',
	    'attributes'  => array(
	        //'placeholder' => 'A small amount of text',
	        //'rows'        => 3,
	        'required'    => 'required',
	    ),
	) );
}

This is my attempt to populate the select with the contact name data:

function contacts_get_array($cmb){

	$contacts = get_post_meta( $cmb->object_id, '_dbem_user_contacts', true );
    $school_contact = array();
	foreach ( (array) $contacts as $key => $contact ) {
        //populate array with name of contact
	    $school_contact[] = esc_html( $contact['name'] );
	}
       return $school_contact;
}

add_action( 'cmb2_init', 'asi_contact_select_user_profile_metabox' );
/**
 * Hook in and add a metabox to add fields to the user profile pages
 */
function asi_contact_select_user_profile_metabox() {
	// Start with an underscore to hide fields from custom fields list
	$prefix = 'dbem_user_';
	/**
	 * Metabox for the user profile screen
	 */
	$cmb_user = new_cmb2_box( array(
		'id'               => $prefix . 'edit',
		'title'            => __( 'User Profile Metabox', 'cmb2' ),
		'object_types'     => array( 'user' ), // Tells CMB2 to use user_meta vs post_meta
		'show_names'       => true,
		'new_user_section' => 'add-new-user', // where form will show on new user page. 'add-existing-user' is only other valid option.
	) );
	$cmb_user->add_field( array(
		'name'             => 'Select Contact',
		'desc'             => 'Choose the default Contact person',
		'id'               => 'select_contact',
		'type'             => 'select',
		'show_option_none' => true,
		'default'          => 'custom',
		'options'          => 'contacts_get_array',
	) );
}

If I actually check the database, what is stored against dbem_user_contacts in the wp_usermeta table is:

a:2:{i:0;a:5:{s:4:"name";s:9:"Test name";s:8:"position";s:25:"Marketing & Comms Manager";s:7:"subject";s:7:"physics";s:5:"phone";s:10:"1234567890";s:5:"email";s:20:"[email protected]";}i:1;a:5:{s:4:"name";s:12:"Test name 2";s:8:"position";s:19:"Science Coordinator";s:7:"subject";s:7:"biology";s:5:"phone";s:10:"1234567890";s:5:"email";s:33:"[email protected]";}}

Hi Kaimee

The problem is that this is user as opposed to post meta, so to retrieve it you need to use get_user_meta()

If you change the function to:

function contacts_get_array($cmb){

   // Get the meta info from the User profile
   $contacts =  get_user_meta( $cmb->object_id, 'dbem_user_contacts', true ) ;

    $school_contact = array();
	foreach ( (array) $contacts as $key => $contact ) {
        //populate array with name of contact
	    $school_contact[] = esc_html( $contact['name'] );
	}
       return $school_contact;
}

this should hopefully work!

Oh my gosh. I was just being blind. Thank you so much for your hard work and patience, that was totally it!

No worries, glad I could help!

Hi i have a somewhat similar issue.

I’m trying to populate multiple checkboxes with an array that should consist of all usernames attached to the site. Making it possible to ‘tack off’ a bunch of the different users.

This is the code i’m using now, but i does not, obviously, work.

function checkboxes_get_array($cmb){
  $users = get_user_meta( $cmb->object_id, 'user_nicename', true );
  $user_array = array();

	foreach ( (array) $users as $key => $user ) {
	  $user_array[] = esc_html( $user );
	}

  return $user_array;
}

add_action( 'cmb2_init', 'project_password_metabox' );

function project_password_metabox() {

	$prefix = '_project_password_';

	$cmb_demo = new_cmb2_box( array(
		'id'            => $prefix . 'metabox',
		'title'         => __( 'Password protected project', 'cmb2' ),
		'object_types'  => array( 'fluxus_portfolio' )
	) );

	$cmb_demo->add_field( array(
		'name'    => __( 'Test Multi Checkbox', 'cmb2' ),
		'desc'    => __( 'field description (optional)', 'cmb2' ),
		'id'      => $prefix . 'multicheckbox',
		'type'    => 'multicheck',
		'options' => 'checkboxes_get_array',
		'inline'  => true,
	) );
}

I’ve tried a solution somewhat similar to the suggestions above, but i cannot seem to make it work.

This is how the options array should look like:

array('check1' => __( 'Check One', 'cmb2' ),
	  'check2' => __( 'Check Two', 'cmb2' ),
	  'check3' => __( 'Check Three', 'cmb2' )
),

I solved it by doing this to the function:

function checkboxes_get_array($cmb){
	$blogusers = get_users( array( 'fields' => array( 'display_name' ) ) );

	$users = array();
	foreach ( $blogusers as $user ) {
		$users[] = esc_html( $user->display_name );
	}

	return $users;
}
