MB User Meta

MB User Meta helps you to add custom fields to user profile.

The extension works only on the back end. If you want to edit user profile on the front end, please see MB User Profile.

Adding fields to user profile

Registering custom fields for users is similar to posts. The only difference here is you need to specify a parameter 'type' => 'user':

add_action( 'rwmb_meta_boxes', function( $meta_boxes ) {
    $meta_boxes[] = array(
        'title' => 'Contact Info',
        'type'  => 'user', // THIS: Specifically for user

        'fields' => array(
            array(
                'name' => 'Mobile phone',
                'id'   => 'mobile',
                'type' => 'tel',
            ),
            array(
                'name' => 'Work phone',
                'id'   => 'work',
                'type' => 'tel',
            ),
            array(
                'name' => 'Address',
                'id'   => 'address',
                'type' => 'textarea',
            ),
            array(
                'name'    => 'City',
                'id'      => 'city',
                'type'    => 'select_advanced',
                'options' => array(
                    'hanoi' => 'Hanoi',
                    'hcm'   => 'Ho Chi Minh City'
                ),
            ),
        ),
    );
    $meta_boxes[] = array(
        'title' => 'Custom avatar',
        'type'  => 'user', // THIS: Specifically for user

        'fields' => array(
            array(
                'name'            => 'Upload avatar',
                'id'              => 'avatar',
                'type'            => 'image_advanced',
                'max_file_uploads' => 1,
            ),
        ),
    );

    return $meta_boxes;
} );

Result:

Data

WordPress provides an identical way to store values in the meta tables for post / term / user. This extension utilizes that API and stores field value in the user meta exactly like post meta.

Getting field value

You're able to use helper function rwmb_meta() to get field value:

$value = rwmb_meta( $field_id, ['object_type' => 'user'], $user_id );
echo $value;

The code is very similar to getting post meta. The differences are:

• In the 2nd parameter, you need to pass 'object_type' => 'user', and
• In the last parameter, you need to pass the user ID

Other parameters are the same as for posts. Please see this documentation for details.

caution

It requires the extension version 1.1+ to use the helper function. If you're using an older version, please update now.

In case you use an older version than 1.1, you can get the field value manually:

$meta = get_user_meta( $user_id, $field_id, true );
echo $meta;

// Or use this code if field has multiple value
$meta = get_user_meta( $user_id, $field_id, false );
foreach ( $meta as $value ) {
    echo $value;
}

Note that the code above returns only raw data of user meta value. It doesn't return meaningful information for images, file, etc. To do that, please add a small piece of code as follow:

// Getting images
$image_ids = get_user_meta( $user_id, $field_id, false ); // Media fields are always multiple.
foreach ( $image_ids as $image_id ) {
    $image = RWMB_Image_Field::file_info( $image_id, array( 'size' => 'thumbnail' ) );
    echo '<img src="' . $image['url'] . '">';
}

These are some helper functions that you can use to retrieve more info:

Field type	Helper function(s)
image, image_advanced, plupload_image, thickbox_image	wp_get_attachment_image_src()
-	wp_get_attachment_image_url()
-	RWMB_Image_Field::file_info( $image_id, $args ); (where $args is an array and accepts only size attribute)
file, file_advanced	get_attached_file()
-	RWMB_File_Field::file_info( $image_id );
oembed	RWMB_OEmbed_Field::get_embed( $url );
taxonomy, taxonomy_advanced	get_term()
user	get_userdata()
post	get_post()
