Using default_cb on a multicheck field

I’ve noticed that this works on admin pages, but not on the front end. That is, if I use cmb2_admin_init as the hook, it works as your screenshot indicates, but if I use cmb2_init it does not.

I’ve been using this box on the front end include file. It displays the checkboxes as expected (using the options_cb callback, but it never calls the default_cb callback.

<fieldset>
	<?php
	$args = array(
		'save_button' => esc_html__( 'Save Changes', 'cmb2' ),
		'cmb_styles'  => false,
		'enqueue_js'  => false,
	);
	echo cmb2_get_metabox_form( 'user_reading_preferences', $attributes['user']->ID, $args );
	?>
</fieldset>

And again, the meta box is on cmb2_init. This has worked as it should, otherwise. I can see the options, correctly update the user’s data for this field, etc. It just doesn’t work with the default callback.

Sure. I don’t have it as a plugin, it’s just in theme files. CMB2 is installed as a plugin.

This code is in functions.php:

// add fields to users
if ( ! function_exists( 'cmb2_user_fields' ) ) :
	add_action( 'cmb2_init', 'cmb2_user_fields' );
	function cmb2_user_fields() {

		$user_preferences = new_cmb2_box( array(
			'id'            => 'user_reading_preferences',
			'title'         => 'Reading Preferences',
			'object_types'  => array( 'user' ),
			'context'       => 'normal',
			'priority'      => 'low',
		) );

		$user_preferences->add_field( array(
			'name'    => 'Subscribe to these regular newsletters:',
			'desc'    => '',
			'id'      => '_newsletters',
			'type'    => 'multicheck',
			'options_cb' => 'user_mc_newsletter_options',
			'default_cb' => 'mp_set_checkbox_default',
		) );
	}
endif;

function mp_set_checkbox_default( $field_args, $field ) {
	error_log( 'field args are ' . print_r( $field_args, true ) );
	error_log( 'field is ' . print_r( $field, true ) );
	return 'check3';
}

function user_mc_newsletter_options( $field ) {
	return [
		'check1' => 'Check One',
		'check2' => 'Check Two',
		'check3' => 'Check Three',
	];
}

I have a custom shortcode that I’m using to render this form. It works like this:

if ( ! function_exists( 'account_preferences_form' ) ) :
	add_shortcode( 'custom-account-preferences-form', 'account_preferences_form' );
	function account_preferences_form( $attributes, $content = null ) {

		if ( ! is_array( $attributes ) ) {
			$attributes = array();
		}

		$user_id = get_query_var( 'users', '' );
		if ( isset( $_GET['user_id'] ) ) {
			$user_id = esc_attr( $_GET['user_id'] );
		} else {
			$user_id = get_current_user_id();
		}

		if ( ! is_user_logged_in() ) {
			return __( 'You are not signed in.', 'user-account-management' );
		} else {
			//$attributes['login'] = rawurldecode( $_REQUEST['login'] );
			// Error messages
			$errors = array();
			if ( isset( $_REQUEST['errors'] ) ) {
				$error_codes = explode( ',', $_REQUEST['errors'] );

				foreach ( $error_codes as $code ) {
					$errors[] = $this->get_error_message( $code );
				}
			}
			$attributes['errors'] = $errors;
			if ( isset( $user_id ) && '' !== $user_id ) {
				$attributes['user'] = get_userdata( $user_id );
			} else {
				$attributes['user'] = wp_get_current_user();
			}
			$attributes['user_meta'] = get_user_meta( $attributes['user']->ID );

			return get_template_html( 'account-preferences-form', 'front-end', $attributes );

		}
	}
endif;

function get_template_html( $template_name, $location = '', $attributes = null ) {
	if ( ! $attributes ) {
		$attributes = array();
	}

	if ( '' !== $location ) {
		$location = $location . '/';
	}

	ob_start();

	$file = get_theme_file_path() . '/' . $this->slug . '-templates/' . $location . $template_name . '.php';
	require( $file );

	$html = ob_get_contents();
	ob_end_clean();

	return $html;
}

Then in my form (the template file), I have this:

<fieldset>
	<?php
	$args = array(
		'save_button' => esc_html__( 'Save Changes', 'cmb2' ),
		'cmb_styles'  => false,
		'enqueue_js'  => false,
	);
	echo cmb2_get_metabox_form( 'user_reading_preferences', $attributes['user']->ID, $args );
	?>
</fieldset>

In the browser, it renders like this:

<fieldset>
	<input name="object_id" value="1" type="hidden">
	<!-- Begin CMB2 Fields -->
	<input id="nonce_CMB2phpuser_reading_preferences" name="nonce_CMB2phpuser_reading_preferences" value="ca980bbe8a" type="hidden">
	<div class="cmb2-wrap form-table">
		<div id="cmb2-metabox-user_reading_preferences" class="cmb2-metabox cmb-field-list">
			<div class="cmb-row cmb-type-multicheck cmb2-id--newsletters" data-fieldtype="multicheck">
				<div class="cmb-th">
					<label for="_newsletters">Subscribe to these regular newsletters:</label>
				</div>
				<div class="cmb-td">
				<ul class="cmb2-checkbox-list cmb2-list">
					<li>
						<input class="cmb2-option" name="_newsletters[]" id="_newsletters1" value="check1" type="checkbox">
						<label for="_newsletters1">Check One</label>
					</li>
					<li>
						<input class="cmb2-option" name="_newsletters[]" id="_newsletters2" value="check2" type="checkbox">
						<label for="_newsletters2">Check Two</label>
					</li>
					<li>
						<input class="cmb2-option" name="_newsletters[]" id="_newsletters3" value="check3" type="checkbox">
						<label for="_newsletters3">Check Three</label>
					</li>
				</ul>
			</div>
		</div>
	</div>
</div>
<!-- End CMB2 Fields -->
<input name="submit-cmb" value="Save Changes" class="button-primary" type="submit">
</fieldset>

My error logs are empty, since the default callback isn’t called.

I hope that’s helpful?

You’re right. I tried putting this into a default wordpress running 2017, and it works fine. There is clearly something else in my theme or other plugins that I’m running, rather than something in this plugin. I’ll go ahead and mark this as resolved. Thanks.
