    I can’t figure out what is wrong with this code, why it isn’t showing up on the page. I’ve been follow this documentation on the wiki.

    functions.php

    
/**
 * Front page carousel metabox
 */

add_action( 'cmb2_admin_init', 'front_page_carousel' );
function front_page_carousel() {

    $prefix = '_fp_';

    $cmb = new_cmb2_box( array(
        'id'            => $prefix . 'carousel_metabox',
        'title'         => __( 'Front-page carousel', 'cmb2' ),
        'object_types'  => array( 'page' ), // Post type
	'show_on'      	=> array( 'key' => 'id', 'value' => array( 18 ) ),
        'context'       => 'normal',
        'priority'      => 'high',
        'show_names'    => true, // Show field names on the left
    ) );

    $group_field_id = $cmb->add_field( array(
        'id'            => $prefix . 'carousel_repeat_group',
	'type'          => 'group',
	'options'       => array(
            'group_title'   => __( 'Slide {#}', 'cmb2' ),
            'add_button'    => __( 'Add slide', 'cmb2' ),
            'remove_button' => __( 'Remove slide', 'cmb2' ),
            'sortable'      => true, // beta
        ),
    ) );

    $cmb->add_group_field( $group_field_id, array(
        'name' => 'Titel',
        'id'   => 'title',
        'type' => 'text',
    ) );

    $cmb->add_group_field( $group_field_id, array(
	'name' => 'Image',
	 'id'   => 'image',
	'type' => 'file',
    ) );

    $cmb->add_group_field( $group_field_id, array(
	'name' => __( 'Link', 'cmb2' ),
	'id'   => 'link',
	'type' => 'text_url',
	'protocols' => array( 'http' ), // Array of allowed protocols
    ) );

}

    content-front-page.php

    
<div class="carousel">
    <?php
 
	$entries = get_post_meta( get_the_ID(), $prefix . 'carousel_metabox', true );

	foreach ( (array) $entries as $key => $entry ) {

		$img = $title = $link = '';

		if ( isset( $entry['image_id'] ) ) {
			$img = wp_get_attachment_image( $entry['image_id'], 'share-pick', null, array(
				'class' => 'full',
			) );
		}

		if ( isset( $entry['title'] ) ) {
			$title = esc_html( $entry['title'] );
		}

		if ( isset( $entry['link'] ) ) {
			$link = esc_html( $entry['link'] );
		}

		echo $entries;
	}
    ?>
</div><!-- .carousel -->

    All I get is an black page with an empty carousel div and tears in my eyes

  • Your get_post_meta() call is using the wrong meta key. You are using the metabox ID when it should be the group field id, '_fp_carousel_repeat_group'

    Hi Justin,

    Was actually the first key i tried, since that is the way it’s done in the documentation. But it’s the same. I’m still not getting anything.

    1. First I did this,
    $entries = get_post_meta( get_the_ID(), '_fp_carousel_repeat_group', true );

    2. Then added the $prefix like this,
    $entries = get_post_meta( get_the_ID(), $prefix . 'carousel_repeat_group', true );

    3. And then finally I switched,
    $entries = get_post_meta( get_the_ID(), $prefix . 'carousel_metabox', true

    But I’m gonna leave it as 2 without the §prefix . going forward and see if I can get it working.

    Sorry but I forgot some details.

    I added var_dump($entries); right before echo $entries;

    And it spits out this. So it is working, I just don’t seem to be able to echo it out.

    array(1) {
  [0]=>
  array(4) {
    ["title"]=>
    string(10) "test title"
    ["image_id"]=>
    int(112)
    ["image"]=>
    string(75) "https://example..com/wp-content/uploads/2016/09/image.jpg"
    ["link"]=>
    string(19) "https://example..com"
  }
}
